Program area “Cooling”
The “Cooling” function with automatic changeover between
heating mode and cooling mode (depending on requirements)
can be used with a mixing circuit.
In order to use the cooling function with further mixing circuits,
the installation of the expansion board (extra-cost accessory) is
required.
The program area “Cooling” must be set by authorised service
personnel during commissioning.
Necessary setting:
Mixing circ 1 = Cool
 page 24, “Determining system setting“, “Mixing circ 1”
IMPORTANT
If a cooling circle mixer is connected, it is imperative to ac-
tivate the function “Cooling”, as otherwise malfunctions
will occur in the mixer connected.
IMPORTANT
The use of cooling requires that you integrate a dew point
sensor in the system. This must then either be connected
in series with the cooling sensor or used instead of the
bridge, if cooling is provided via the ow cooler.
NOTE
The minimum ow temperature of cooling is factory set to
18°C. This value can be changed in the menu “Determin-
ing temperatures” in the menu item “min. ow cooling”
IMPORTANT
For brine/water heat pumps with integrated hydraulic
components, do not set the minimum ow temperature of
cooling to <18 °C.
 page 22, “Determining temperatures“
If the cooling function is set, the symbol
