Technical manual ECL Apex 10, control parameters and functions
Introduction
This manual lists all readouts and settings of the ECL Apex
10. With the help of this list, it will be possible to enter all
relevant settings. As the ECL Apex 10 has a dynamic user
interface, each choice you make will rule out other choices.
This means that not all the listed settings will be available in
the configuration process.
The circuit type is illustrated with pictograms right above
each readout / setting depending on the circuit it is valid for:
The heating circuit as and the domestic hot-water (DHW)
as .
Provided that the Pt 1000 sensors are correctly configured,
the value 250 will correspond to disconnected or
deactivated and -150 to short-circuited.

Technical manual ECL Apex 10, control parameters and functions
Weather compensation
The ECL Apex 10 is a weather compensated flow
temperature controller, which means that the ECL Apex 10
controls the heating circuit temperature in accordance with
the outdoor temperature.
The ECL Apex is controlled according to the following
control strategies:
Constant temp. =
Constant temperature control (no weather compensation)
6-pt weather comp. =
Weather compensation according to a heat curve with 6
points
Std w.comp. + room T =
Standard weather compensation + room temperature
control
6-pt w.comp. + room T =
Weather compensation according to a heat curve with 6
points + room temperature control
Settings
-- Heat curve --
The heat curve consists of four parameters: slope, parallel
displacement and min/max flow temperature.

Is displayed if ‘Control strategy’ is ‘Std w.comp. + room T’.
The heat curve slopee depends on the heating system and
area specific design parameters.
Example I
Design parameter:
Designed outdoor temperature (T
out
) -12 °C
Designed flow temperature (T
flow
) 80 °C
Designed room temperature (T
room
) 20 °C
For designed flow temperature higher than 40 °C, the heat
curve slope (S) can be calculated as:
S =
T
flow
- 25
2.5 x T
room
- T
out
- 30
S =
80 - 25
2.5 x 20 - (- 12) - 30
S ≈ 1.7
Example II
Design parameter:
Designed outdoor temperature (T
out
) -20 °C
Designed flow temperature (T
flow
) 35 °C
Designed room temperature (T
room
) 21 °C
For designed flow temperatures lower than 40 °C, the heat
curve slope (S) can be calculated as:
S =
T
flow
- 20
1.3 (2.5 x T
room
- T
out
- 30)
S =
35 - 20
1.3 (2.5 x 21 - (- 20) - 30)
S ≈ 0.3
For quick setting, the graph can be used. The graph
is intended for a T
room
of 20 °C. If the design data from
example I is used, the slope will be approx. 1.7.

The parallel displacement has a direct influence on the flow

).
Flow temp. - max 20a
Setting range Factory setting
10 ... 150 °C 90 °C
The set max flow temperature must be higher than the min
flow temperature.
The max flow temperature is set to avoid a too high flow
temperature, e.g. when the heating system supplies the
floor heating system.
Flow temp. - min 20a
Setting range Factory setting
10 ... 150 °C 10 °C
The set min flow temperature must be lower than the max
flow temperature.
The min flow temperature is set to avoid a too low flow
temperature, e.g. when the heating system is supplied from
cast-iron boilers.
If the outdoor temperature is higher than 10 °C, it is
recommended only to change the parallel displacement.
For outdoor temperatures below -5 °C, it is recommended
only to change the slope.

-- Room temp. influence --
This limitation is based on a PI regulation where P
(influence) responds quickly to deviations and I (time
constant) responds slower and over time removes the small
offsets between the reference and actual measured values.
This is done by changing the flow temperature reference.
Influence - max 3a
Setting range Factory setting
-9.9 ... 0.0 -4
Can only be set if ‘Room temperature’ sensor is selected and
‘Control strategy’ is either ‘Std w.comp. + room T’ or ‘6-pt
w.comp. + room T’.
Influence - min 3b
Setting range Factory setting
0.0 ... 9.9 0
Can only be set if ‘Room temperature’ sensor is selected and
‘Control strategy’ is either ‘Std w.comp. + room T’ or ‘6-pt
w.comp. + room T’.
Time constant ?
Setting range Factory setting
600 .... 60000 s 6000 s
Can only be set if ‘Room temperature’ sensor is selected and
‘Control strategy’ is either ‘Std w.comp. + room T’ or ‘6-pt
w.comp. + room T’.
When the value is set to 6000 s, the I attribution is OFF.
There are two basic principles for setting the room
temperature influence:
A: Max room temperature limitation
Use this limitation if your heating system is fully equipped
with radiator thermostats and you also want to obtain a max
limitation of the room temperature. The controller will allow
for free heat gains, i.e. solar radiation or heat from a fire
place, etc.
The max influence determines how much the room
temperature should influence the flow temperature
reference.
Influence
Desired room
temperature
Ro
om
temperature
Influence - max
Example I
The actual room temperature is 2 degrees too high.
The influence - max is set to -4.0.
The influence - min is set to 0.0.
The heat curve slope is 1.8.
Result:
The flow temperature reference is changed by
2 x (-4.0) x 1.8 = -14.4 degrees.
B: Reference room temperature control
Used if your heating system is not equipped with radiator
thermostats and you select the room with room sensor as a
temperature reference for the rest of the rooms.
(However, should you have a few radiator thermostats
installed, make sure that they are fully open).
The room temperature sensor in the reference room
registers the difference between the desired and the actual
room temperature. The flow temperature reference will be
corrected to eliminate this difference.

The influence - max is set to -3.5.
The influence - min is set to 2.0.
The heat curve slope is 1.8.
Result:
The flow temperature reference is changed by
2 x 2.0 x 1.8 = 7.2 degrees.
Example III
The actual room temperature is 2 degrees too high.
The influence - max is set to -3.5.

Outdoor setpoint
If the outdoor temperature during total stop at setback
or standby falls below the outdoor setpoint, the flow
temperature reference will be increased by the difference
between the outdoor setpoint minus the actual outdoor
temperature multiplied by the gain.
Example:
Outdoor setpoint: 0 °C
Gain: 2.0
Actual outdoor temp.: -14 °C
Result:
The flow temperature reference will be increased by 2 x 14
= 28 degrees.

Reference ramping is the time in which the flow

in the supply.
Temperature ˚C
Reference ramping time
Time (min.)
In order to avoid load peaks in the supply network, the flow
temperature reference can be set to increase slowly after a
period with setback temperature. This causes the valve to
open slowly.
Boost 123
Setting range Factory setting
0 ... 99% 0%
The boost shortens the heating-up period by increasing the
flow temperature by the percentage you set.
In order to shorten the heating-up period after a setback
temperature period, the flow temperature reference can be
increased temporarily (max 1 hour). At optimizing the boost
period is limited according to the calculated pre-comfort
period.
If a room temperature sensor is connected, the boost stops
when the room temperature is reached.
The boost also stops at the end of an optimizing period.

When the return temperature falls below or gets higher
than the set value, the controller automatically changes the
desired flow temperature to obtain an acceptable return
temperature.
The return temperature limitation for the heating circuit
is based on the outdoor temperature. If no outdoor

the calculation is 0 °C. When the outdoor temperature drops,
a higher return temperature typically is accepted.
The relationship between the return temperature limits and
outdoor temperature is set in two coordinates.
The upper limit coordinates are set in X2 and Y2 and the
lower limit coordinates in X1 and Y1.

This limitation is based on a PI regulation where P

This is done by changing the flow temperature reference.
How the universal influence operates depends on type of
sensor connected to the input. This function is very flexible
and is only used for very special applications.
The universal influence allows you to modify the flow
temperature reference based on any sensor type connected
to the ECL Apex 10, e.g. temperature, pressure or analog
inputs. If the measured value deviates from the user-defined
setpoint, the flow temperature could be increased or
decreased.
