Conguration - 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/o 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 nd
additional information in Chapter 5 of the manual.

• 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
