1.2 Introduction
Congratulations on your excellent choice of purchasing an Hanging Bird Scale!
In order to realize the full benefit from this product it is important that it is installed, commissioned and
operated correctly. Before installation or using the fan, this manual should be studied carefully. It is also
recommended that it is kept safely for future reference. The manual is intended as a reference for
installation, commissioning and day-to-day operation of the Munters Controllers.
1.3 Notes

2 Safety aspects
Take the following steps to ensure equipment safety and proper functioning.
2.1 Grounding
•
Always connect temperature and sensor shields to earth ground
.
•
Avoid mixing high voltage wiring with sensor and low voltage wiring
.
•
Keep the controller as far as possible from heavy contactor boxes and other sources of electrical
interference
.
•
Do not connect communication wire shields, which go from one house to another at both ends.
Connect them at one end only. Connection at both ends can cause ground loop currents to flow,
which reduce reliability
.
•
The COM connection for communications is not the shield wire. The COM, RX and TX wires must
connect to each other at all controllers
.
2.2 Checking the battery level
•
Check the battery once a year. The output must be 2.7 volts (minimum). Authorized personnel
only must replace the battery if the output is below the minimum required level or every five year
s.

(Figure 1), press the ▼▲ keys. The following hot keys are displayed (Figure 2).
Figure 1: Main screen
3.3.3 Cold Start
Cold Start procedure resets the controller to its original factory settings. It should be performed after
software version replacement, reinstallation or when instructed by Munters' electrician.
To perform cold start, press the following keys simultaneously:
▲
▼
<SELECT>
3.4 Menu structure
The Main screen is in the root, the main menus are on the next line. In order to return to the main screen
at any point, press and hold SELECT.
•
To reach a main menu (the level below the Main screen), press the SELECT key.
•
To reach any level below the main menus, press the PROG. key. For example, to view
information of HUM DELAY (m) from the main screen, the following keys should be pressed:
SELECT > TARGET HUM >PROG. , until the desired parameter is displayed.
X represents a number. For example, Growth Day: xxx means a specific growth day number, such as the
9
th
day.
Figure 2: Menu Structure
3.5 General features
•
To change the Main screen display, click the last Hot Key.
•
If a screen other than the Main screen is being displayed for five consecutive minutes, the system
returns to the Main screen display automatically (in menus only, not including hot keys).
•
When a value is being modified with the arrow keys (either ▲ or ▼), the changes occur at a rate
of 2 changes per second. After holding down an arrow key for 3 seconds, the changes will
occur at a rate of 10 changes per second.
•
If the system displays one of the Hot Keys and no alarms arise, the screen will be refreshed every
second. If the system displays a Hot Key screen and alarms arise, both the Hot Key screen and
the alarm will be displayed alternately every three seconds. If more than one alarm is activated,
the Hot Key screen will display the different alarms alternately.
3.6 Alarms
Table 2 shows the list of alarms. The alarms can be viewed on the main screen. The main screen shows
the alarms and the main screen display alternately. Smart A navigates between the alarms
automatically.

Automatic temperature adjustment
5.1.1 Working with a curve
This menu defines the target temperature curve. The next parameters display the result of the user's
selection of the Curve (YES/NO) parameter in System menu:
If Yes has been chosen: the target temperature is set automatically, according to the following
parameters:
o
1
st
TEMP: First temperature point for creating a curve.
o
FIRST DAY: First growth day to create a curve.
o
LAST TEMP: Last temperature point for creating a curve.
o
LAST DAY: Last growth day to create a curve.
5.1.2 Working without a curve
If NO has been chosen, the TRGT TEMP is the only parameter that is displayed, and it is changed
directly by the user.
NOTE The value of the
Last Day
parameter must be greater than the
First Day
parameter.
If the
First Day
parameter has the same value as the
Last Day
parameter, the
Curve
parameter (in
System
menu) will not exist, and the controller will use the
Last Temp
parameter as the
Target Temp
menu.
5.1.3 Automatic temperature adjustment
If the Growth Day is less than the First Day parameter, Target Temp will be set to the temperature
defined in the 1
st
Temp parameter. During the period between the First Day parameter and the Last Day
parameter, the controller automatically adjusts the temperature so that Target Temp changes gradually
and evenly towards Target Temp as defined in the Last Day parameter. Once the Last Day parameter is
reached, Target Temp will remain permanent at the temperature defined for the Last Day parameter.
Consider the following example (Figure 4):
•
1
st
Temp is 34.0º C
•
First Day is 5
•
Last Temp is 21.0º C.
•
Last Day is 21
As long as Growth Day is either less than or equals five, the controller keeps a Target Temp of 34.0º C.
After First Day, the system adjusts Target Temp that changes. This change is gradual and lasts until Last
Temp is reached (on Last Day). From Growth Day 21 onward, the Target Temp is 21.0º C

5.2 Target humidity
This menu enables to define target humidity. The parameters are as follows:
•
Target Hum: Above this value, humidity treatment (see below) will be performed.
•
Hum Dur (s): The number of seconds of humidity treatment
•
Hum Delay (m): The number of minutes the controller "waits" before Humidity Treatment begins.
Table 4 summarizes the target humidity parameters.

Hum Delay (m):

5.2.1 Humidity Treatment
Humidity treatment is the addition of ventilation for the specified duration time. For instance, in the table
above, if the target humidity of 65% is exceeded after the delay time has passed, humidity treatment will
start until humidity drops below 63% [target -%2].
5.2.2 How is humidity treatment performed?
Ventilation is added to the current ventilation in the one of the following ways:
•
In minimum ventilation: if a cycle is set, CYCLE ON time is increased by the duration value, and
OFF time is decreased by the duration value n (if OFF time is less than 5 seconds, operation is
continuous).
If no cycle is set, a cycle will be activated between duration (ON time) and delay (OFF time).
•
Above minimum ventilation: Humidity treatment activates the fan with the next closest ON time.
See the explanation regarding cycle in the next section.
5.3 Minimum ventilation fan cycle
This cycle defines the ON / OFF times of the Minimum Ventilation Fans. There are two ways to create a
minimum ventilation cycle: (1) without a curve or; (2) with a curve.
NOTE Defined in SYSTEM MENU - Curve (Yes/No).
•
Without a curve
•
With a curve
5.3.1 Without a curve
Fixed ON and OFF times are set.
•
Cycle on: Number of seconds in minimum ventilation to operate the fan(s).
•
Cycle off: Number of seconds in minimum ventilation in which the fans do not operate.
5.3.2 With a curve
If there is a curve, the controller builds it according to the On/Off times of the first and last days, which
were set on the temperature curve. It uses the following parameters:
The controller builds the curve of the ON / OFF times according to the first and last day, which are set
in the Target Temp menu. The following parameters define the beginning and ending reference points
(in seconds) for the curve to follow.
•
1st day on: Define the ON time (in seconds) for the minimum ventilation fans; marks beginning
reference point for the cycle’s curve
•
1st day off: Define the OFF time (in seconds) for the minimum ventilation fans; marks beginning
reference point for the cycle’s curve
•
Last day on: Define the ON time (in seconds) for the minimum ventilation fans; marks ending
reference point for the cycle’s curve
•
Last day off: Define the OFF time (in seconds) for the minimum ventilation fans; marks ending
reference point for the cycle’s curve
