Mechanical Design and installation

The unit consists of two parts: (a) The power case with attached mounting plate and (b) the front part.

Mounting location

• On an easy accessible interior wall, approx. 1.5 m (4.5’) above the floor in an area of average temperature.

• Avoid exposure to direct sunlight or other heat sources, e.g. the area above radiators and heat emitting electrical

equipment.

• Avoid locations behind doors, outside walls and below or above air discharge grills and diffusers.

• Location of mounting is less critical if external temperature sensors are used

Installation

1. Connect the wires to be connected to the terminals of the power case according to wiring diagram

2. Install the mounting plate to the flush mounting box. Make sure that the nipple with the front holding screw is

facing to the ground. Make sure the mounting screw heads do not stand out more than 5 mm (0.2”) off the

surface of the mounting plate.

3. Ensure that the jumpers are set correctly.

4. Slide the two latches located on the top of the front part into the hooks at the upper side of the mounting plate.

5. Carefully lower the front part until the interconnector reaches the mounting-plate. Continue pressing in a gentle

way until the front part is fully connected. While inserting the connectors, a slight resistance can be felt. This is

normal. Do not use excessive force!

6. With a Philips-type screw driver of size #2, carefully tighten the front holding screw to secure the front part to

the mounting plate. This screw is located on the front lower side of the unit. There is no need to tighten the

screw too much.

Control Functions

Lp1: Temperature control loop: Signal input: either internal or external passive temperature probe

Lp2: Universal control loop: Signal input: analog input or internal humidity sensor (-H version only)

Each control loop may utilize 6 binary and 2 PID control sequence functions. Control sequences will be activated once

assigned to a physical or logical output.

Manipulation of the set point

Standby set point shift X

SBY

: This function shifts the set point while the operation mode is standby. The heating set

point W

is reduced and the cooling set point W

increased by the value of the standby set point shift X

SBY

Dead Zone Span X

: The dead zone span lies between the heating and the cooling set point.

Minimum and Maximum Set Point Limits: Limits the adjustable range of the loop set point. The limits for heating and

cooling sequence may be chosen individually.

Cascade Control: The output of the primary control loop determines the set point of the secondary control loop. It is

possible to choose only the direct or reverse sequence or both of them. The output of the set point providing control loop

is spanned between the minimum and maximum set point limits. The set point limits for heating and cooling sequence are

defined individually.

Summer – Winter Compensation: Shift the set point either towards the set point minimum (negative shift) or the set

point maximum (positive shift) depending on an external input signal. This is done to compensate the set point due to a

change in the environment. It is most commonly applied to outside temperature. Summer-Winter compensation is

activated through parameter 1L07 or 2L07.

IP22 selects the compensation input signal, either external temperature or analog input.

The winter compensation is active when the outside temperature drops below the upper limit of winter compensation

IP25. Depending on parameter IP23, the setpoint is now shifted towards the heating setpoint minimum or maximum.

The maximal compensation is reached when the temperature reaches the lower limit IP24. The actual set point will in this

case be equal to the minimum heating set point limit for a negative shift or the maximum set point limit for a positive

shift.

The summer compensation is active when the outside temperature exceeds the lower limit for summer compensation

Proportional Control:

Proportional-band X

: The proportional part is defined through the p-band. A narrow P-band increases the sensitivity of

the controller. Typical values used are 1 – 1.5K for heating, 2 – 3K for cooling sequences.

The P-band should be extended in case the ID-Part is active, to prevent instability.

Integral & Differential Control:

The algorithm used reduces the swinging tendency of the control loop and improves a direct approach of the current value

to the setpoint. The ID part is defined by two parameters:

The time interval TI specifies how fast the control sequence reacts. A low value (short interval) increases the swinging

tendency and with it the risk of an instable loop. A high value (long interval) slows than reaction time.

The integral gain factor KI specifies how strong the control sequence reacts. Opposite to TI a high gain factor increases

instability and a low factor delays the response of the controller.

We recommend the following values:

For air based heating systems: TI = 3s, KI = 1.0

For floor heating systems: TI = 5s, KI = 0.5

For air cooling systems: TI = 3s, KI = 1.2

For humidifying systems: TI = 60s, KI = 0.4

For dehumidifying systems: TI = 70s, KI = 0.3

Pressure Control (VAV): TI = 1s, KI = 0.8 (depending on speed of actuator KI varies)

Binary Control

Each loop has three reverse- (heating) and three direct- (cooling) acting binary sequences. The offset to the setpoint is

adjustable for each sequence. The switching hysteresis is adjustable per control loop.

Action of stages: The stages may be activated according three different patterns:

One at the time: Only one stage is active at the time. The lower stage will be switched off when the higher stage gets

active. Example: fan speed control.

Cumulative: Multiple stages are active at the same time: The lower stage stays activated when the higher stage

switches on. Example: Electrical heating stages

Binary coded: In the first step only the first stage is active; in the second step only the second stage. In the third

step both stage 1 and stage 2 are switched on. This is used for heating stages. The size of the

second heating stage should be doubled the size of the first heating stage. For example 100W for the

first stage and 200W for the second stage. With two outputs we could create the following steps: 1.

Step 100W, 2. step 200W, 3. step 300W.

Switching Hysteresis: Defines the difference between switching on and switching off of a digital sequence. A small

hysteresis will increase the number of switching cycles and thus the wear on associated equipment.

Delayed switching. Cumulative Heating/ cooling stages will not switch simultaneously with stage 1, in case of a sudden

demand or at power on. Stage 2 will not start earlier than 5 seconds after stage 1 has been initiated.

Input Configuration

General

Alarms: Each input features low and high limit alarms. Each alarm is defined with a limit, a hysteresis and an enable

parameter. The limit specifies the input signal level required to trigger the alarm. The hysteresis defines the difference

between input signal and limit required to return the alarm state to normal. Once an alarm is triggered it will be displayed

as ALA1, ALA2, ALA3 and ALA4. Each alarm needs to be acknowledged by pressing the RIGHT key.

ALA1 = Lower limit of the input signal of control loop 1 (temperature) has been reached

ALA2 = Upper limit of the input signal of control loop 1 (temperature) has been reached

ALA3 = Lower limit of the input signal of control loop 2 (universal) has been reached

ALA4 = Upper limit of the input signal of control loop 2 (universal) has been reached

Averaging function: Averaging function is used to prevent unwanted fluctuation of sensor signals. The controller

measures every second the signal inputs. The input signal is now built over a number of measured values. Select how

many values should be used to calculate the averaging signal. Control speed will slow down when a large number of

samples are used for an averaging signal. This should be taken into account when defining the control parameters.

Compensation: Adjust input values if required

The TCY3 includes an NTC-based passive temperature sensor. A sensor

of the same type can be connected as alternative control input or as

input for additional functions. The accuracy of the temperature input is

shown in the table to the right. Specified accuracy can only be

guaranteed by using a manufacturer approved temperature sensor. For

best results use Sxx-Tn10 sensors.

1.0

Choose the active temperature input (intern or extern) of control loop 1

with IP00.

Additional functions of the external temperature input:

Following additional functions are available, in case the external temperature input is not used as input for control loop 1.

Toggle of Standby and

Comfort operation modes

Standby and Comfort modes are controlled through an external contact by connecting

the external temperature input to ground

Activation Delay: Defines the delay the binary contact has to be open before

standby mode is activated.

This function may be used together with key card switches for hotels or motion

detectors for offices.

Remote Enable Opening the external temperature input will force the unit into the OFF operation

mode. The operation mode cannot be overridden by using the terminal or time

schedules. Connecting the external temperature input to GND returns control of the

operation mode to the terminal and time schedule. This function may be used as

window contact to prevent loss of energy.

Heat-cool changeover with

external switch

Control heat and cool setting of your controller from a central location by switching a

contact to GND. Note: all ground levels of involved controllers must be the same.

Choose if heat or cool is to be active when contact is open.

Auto changeover with media

temperature sensor

The external input may be used to automatically determine heating or cooling mode.

Connect a qualified passive sensor to the external input and measure the temperature

of the supply media. Heating or cooling mode are activated once the supply

temperature is above or below the respective limits. The limits may be defined in

software. Standard is 16°C (60°F) for cooling and 28°C (82°F) for heating.

Universal Input:

The analog input signals may be configured with a jumper to 0-10V, 0-5V and 4-20 mA. The jumper is

located on the front side of the power part. The drawing on the right indicates the jumper placement for each

signal type. The factory setting is 0-10 VDC. Only place the jumper vertically.

The range of the input signal can be specified in software by setting a minimum and a maximum limit. The

limits are in percent of the full range.

The display value of the input signal may be specified according to its measuring range. For example a

pressure sensor has a 4-20 mA output and a pressure range of 0 – 200 Pa. It is possible to transform the

input signal into a different dimension by setting the lower and upper measuring range limit according to the

features of the sensor device. In our example the display will read 100 for a 12 mA signal. Range values

below 100 will have a resolution of 0.5, below 50 of 0.2 and below 25 of 0.1.

Humidity Input (-H Version)

The TCY3-T0121R-H includes a capacitive-based humidity sensor with 3% accuracy. The sensor may be used as control

input, as feedback or display input. It will replace the analog input on loop 2, if configured as control input.

Output Configuration

General

An output must be assigned to a function or a control loop using the OP parameter set. Assigning an output to a control

function will automatically activate the respective function. Unassigned functions are not active.

Alarm function

The alarm setting defines how the output should respond to a specific alarm

condition. In case of an alarm the output may be switched on (100%) or off (0%).

The alarm situation takes precedence over operating state and calculated output

signal.

Analog Output

0…10V

0…20mA

█

The analog output may be configured with jumpers for 0-10 VDC or 0-20 mA control signals. The jumper is

located on the front side of the power part. The drawing on the right indicates the jumper placement for each

signal type. The factory setting is 0-10 VDC. Only place the jumper vertically. Only place one jumper for one

signal. The signal range can be specified in software by setting a minimum and a maximum limit. The limits are

in percent of the full range.

Special functions of the analog output:

Manual Positions the output directly with a set point. The number of positioning steps can be

selected: 2, 10, 100 steps

Dehumidifying

(only for 4-pipe systems)

The maximum value is taken of both direct acting PID sequences (Cooling and

dehumidifying). Cooling will start to operate if the humidity gets too high, even if there is

no cooling need, thus the heating will be forced to come into play, which in turn

dehumidifies the air.

VAV In the VAV control sequence, at peak cooling the airflow setpoint is the maximum amount

of air the VAV box is set to deliver. It may be adjusted through the maximum limit on the

analog output (OP03). As cooling requirements decrease, airflow dwindles until it reaches

its minimum setpoint. This setpoint will be based on the airflow needed at design cooling

and is typically 10% to 15% of maximum cooling airflow. Minimum airflow can be adjusted

by the minimum limit on the analog output (OP02). When it reaches this minimum, the

system is in its dead band and is neither heating nor cooling. As the system moves into

heating mode, the airflow rate increases until it reaches the maximum airflow required for

heating mode. This is typically 30 to 50% of maximum airflow of cooling mode. The

parameter for this is called VAV function: maximum limitation in heating mode (OP05).

Binary-Function

(AER-C13)

The analog output may be converted into three binary outputs by use of an accessory

(AER-C13). Instead of the PID sequence, the on/off sequence for 3 binary sequences is

enabled. The binary output may be enabled for all the lp1 and lp2 sequences.

Switching voltages are fixed to following output levels:

Stage 0 Stage 1 Stage 2 Stage 3

0% 40%

70%

100%

Sensor and setpoint

feedback

Internal humidity and temperature sensor values as well as set points may be transmitted

on the analog outputs. Minimum and maximum value of the feedback value may be set for

loop 1 (Temperature), Loop 2 is fixed to 0…100%. The alarm output level will be activated

in case a sensor is in error mode.

Feedback of floating output The position of the floating output is calculated according to the sum of opening and

closing time of the actuator. The total running time of the actuator must be entered.

Binary Outputs

If OP11 is in the OFF position, DO1 and DO2 may be used as binary outputs. They may be used for binary sequences or

other special functions:

Additional functions oft he binary output:

Dehumidifying

(only for 4-pipe systems)

The maximum value is taken of both direct acting sequences of LP1 and LP2 (Cooling and

dehumidifying). Cooling will start to operate if the humidity gets too high, even if there is

no cooling need, thus the heating will be forced to come into play, which in turn

dehumidifies the air.

Operation State (On if

operation state is ON)

The output is ON if either comfort or standby mode are active. In energy hold off mode

(EHO) the output is off.

Operation State with switch

off delay 60s

The output is ON if either comfort or standby mode are active. In energy hold off mode

(EHO) the output is off with a switch off delay of 60s. This is required for fan supported

heating or cooling coils with mold protection.

Output while demand on

any output, switch off delay

60s

The output is ON if demand exists on any other output. The output switches off with a

fixed delay of 60s if there is no more demand. This function is usefull for fan supported

heating or cooling devices.

Indication of the fan symbol

By enabling this function, the fan symbol is shown on the display whenever DO1 is active.

Floating Outputs

Enabling OP11 changes DO1 and DO2 into a floating output for a PID loop. In this case the running time of the actuator

needs to be specified. Running time is defined as the time required for the actuator to run from fully open to fully closed

or vice versa. Actuators with a fixed running time are recommended. Once fully open or fully closed the running time for

the actuator is extended for a full run time cycle. This will allow the actuator position to be synchronized in case it has

been moved during off time or an actuator with variable running time was used.

Switching difference on floating output: Use the Switching difference parameter to reduce the switching frequency of the

actuator. The actuator will only move, if the difference to the current actuator position is larger than this parameter.
