A prerequisite for using the heating system in cooling mode is that a room
thermostat is installed in the heating system to prevent condensate
formation.
There are two installation options:
• Room thermostat with integrated dew point monitor sensor (CR10H
or ModuLine 1010H).
• Room thermostat (CR10 or ModuLine 1010) in combination with
dew point monitor sensor in the heating system.
Use of a CR10H or ModuLine 1010H room thermostat is recommended
for non-condensing cooling mode.
Installing a room thermostat with integrated dew point monitor
(humidity sensor) increases the reliability of cooling mode since the flow
temperature in this case is automatically controlled via the control unit
with reference to the current dew point.
▶ Installing the room thermostat with integrated Dew point humidity
sensor ( instructions of the room thermostat).
▶ Electrical connection (Chapter 6.8.4).
If a room thermostat is used without an integrated dew point monitor
(humidity sensor), an additional dew point monitor (humidity sensor)
must be installed in the heating system.
▶ Fit the room thermostat in order to adjust the cooling mode of the
heating system ( observe instructions for the room thermostat).
▶ Electrical connection (Chapter 6.8.4).
5.7.5 Installation with swimming pool
NOTICE
Danger of faults!
If the swimming pool mixer is installed in the wrong location in the
system, faults may occur. The swimming pool mixer must not be installed
in the flow where it could block the pressure relief valve.
▶ Assemble the swimming pool mixer in the return to the indoor unit (as
shown in the example image for swimming pool installation).
▶ Mount the tee in the flow from the indoor unit upstream of the bypass.
▶ Do not install the swimming pool mixer as heating circuit in the
system.
A prerequisite for using the swimming pool heating is the installation of a
swimming pool module (accessory).
▶ Installing the swimming pool ( swimming pool instructions).
▶ Installing the swimming pool mixer.
▶ Insulate all pipes and connections.
▶ Install the pool module ( Instructions for the pool module).
▶ Electrical connection (Chapter 6.8.6).
▶ Set the elapsed time of the swimming pool diverter valve during
commissioning ( instructions for control unit).
▶ Make the necessary settings for the swimming pool mode (
instructions for control unit).
