Thermal Domestic hot water preparation is
initiated or terminated via a thermostat
on the domestic hot water tank.
No temperatures can be set in the
controller
NOTE
Connect domestic hot water thermostat on the same ter-
minals as the domestic hot water sensor (low voltage). The
domestic hot water thermostat must be suitable for low
voltage (oating contact).
Thermostat closed (= signal On) = Domestic hot water re-
quirement.

CP Setting CP means circulation pump.

For the corresponding settings, please refer to the description
of the circulation pump in the operating manual part 1, pro-
gram section “Domestic hot water”, section “Circulation“.
h.wCP Setting h.w.CP means that the CP
output will be active during domestic
hot water preparation and switch o
30 seconds after domestic hot water
preparation is complete.
NOTE
If the “service water2” menu eld is not visible, you must
make this setting in the “FlexCong” menu under “OUT2”.

SW+HP max
Maximum running time domestic hot
water preparation + Heat pump
After the set time has expired, the 2nd heat generator in the
domestic hot water preparation energises, but only if this has
been released previously in the heating mode!
Defr cycle max
Defrost cycle time, maximum time
between two defrost processes
You can nd the time to be set for the relevant L/W device in
the operating manual. If you do not nd any data there, the
following applies:
