1. Go to Configuration menu
2. Select Common control
3. Select functions for thermostat
Configuration - continued
The setup menu has now changed.
It now shows more settings all of
which are based on the selected
plant type.
For example, earlier we selected 3
evaporators. This means that 3 sec-
tions are now displayed.
In our example we select:
• On/off thermostat
• Individual thermostat on each
section
• Night setback
• No melt function, as this is a frost
appliance
The settings are shown here in the
display.
Depending on your settings, further settings may then
be available for the selected functions.
This list in the right-hand column contains all the pos-
sible functions that may be made available in one way
or another.
If you want to know more about the individual func-
tions than the brief description below, you will find
additional information in Chapter 5 of the manual.

Thermostat type
Choose from the following thermostat functions:
• 1 valve for all /common ON-OFF thermostat
Here, only one valve is used for all evaporators. The tem-
perature is controlled by an ON/OFF thermostat on the
basis of the settings in the A section.
• 1 valve per evap/ common ON/OFF thermostat
Here, one valve per evaporator is used. The temperature
is controlled in all evaporator sections by an ON/OFF
thermostat on the basis of the settings in the A section.
• 1 valve per evaporator / individual ON/OFF thermostat
Here, one valve per evaporator is used. The temperature
is controlled individual by ON/OFF in each evaporator
section.
• 1 valve per evaporator /individual modulating thermostat
Here, one valve per evaporator is used. The temperature is
controlled individually in each evaporator section accord-
ing to a modulating principle
External reference via voltage
Select whether to use an external voltage signal for dis-
placement of the thermostat reference.
Offset at max. signal
Offset value at max. signal (5 or 10V).
Offset at min. signal
Offset value at min. signal (0,1 or 2V).
Day/ night control
Select whether the thermostat temperature is raised for
night operation
(Night offset values must be set in the individual sections
and in Kelvin)
Night displacement via DI
Select whether night displacement is to take place with
an input signal. (Alternatively, the signal can be generated
from the internal weekly schedule or from the system
administrator via data communication.)
Thermostat band
Select whether you want the thermostat to switch be-
tween two reference settings (the values can be set in the
individual sections)
Select whether the switch should be initialised by pulse
pressure or by a switch.
Thermostat band select via DI
Select whether the reference is to be made with a signal on
a DI input.
Melt function
Select whether you want the controller to perform a melt-
ing function
Melt interval
Set the time period between two melting intervals
Melt time
Set the melting time
Flood Evap
Choose from the following functions:
• Disconnected. Liquid flow is not permitted
• Liquid flow SH only. Stopped by a signal from the system
device.
• Liquid flow Common DI. Stopped by a common DI signal
