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 (floating contact).
Thermostat closed (= signal On) = Domestic hot water re-
quirement.
Service water 2 Domestic Hot Water 2
CP Setting CP means circulation pump.
 For the corresponding settings, please refer to the description
of the circulation pump in the operating manual intended for
end customers, found in program section "Domestic hot wa-
ter" under the section entitled "Circulation".
h.wCP Setting h.w.CP means that the CP
output will be active during domestic
hot water preparation and switch off
30 seconds after domestic hot water
preparation is complete.
Service water 3 Domestic Hot Water 3
with CP Additional circulation pump runs
during domestic hot water preparation
no CP Additional circulation pump does
not run during domestic hot water
preparation
Service water 4 Domestic Hot Water 4
set value Heat pump attempts to reach the set
setpoint value of the domestic hot
water temperature
Service water 5 Domestic Hot Water 5
with HSP Heating circulation pump runs always
during domestic hot water preparation
no HSP Heating circulation pump does not run
during domestic hot water preparation
par HUP Heating recirculation pump operates
parallel with domestic hot water
preparation if a heating requirement
exists. If the heating limit is exceeded,
the heating circulation pump switches
off.
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 find the time to be set for the relevant L/W device in
the operating instructions. If you do not find any data there,
the following applies:
 page 40, "Overview: Defrost cycle, Air defrost, Flow Max"
Defrost. Air Air defrost
No Air defrost not released
Yes Air defrost generally released above
the set temperature

 Approved appliances, see page 40, "Overview: Defrost cy-
cle, Air defrost, Flow Max"
ATTENTION
Do not set an "air defrost" on non-approved appliances.
Defr.Air max Maximum duration of air defrost
Defrost 2
Option only possible for L/W devices with 2 compressors
with 1CP Defrost with only one compressor
with 2CP Defrost with two compressors, if these
also supply before defrosting
Pump opt. Pump optimisation
No Heating circulation pumps always
run, unless another supply type is
requested (domestic hot water, ...) or
the device is switched off
Yes Setting only effective with an outdoor
temperature > 0 °C.
Heating circulation pumps are
switched off, if required
The heating circulation pumps will
be switched if the heat pump has
not been requested for more than 3
hours. The heating circulation pumps
will then cycle for 5 minutes every 30
minutes until the heat pump receives
another request.
If the external temperature is above
the return setpoint temperature, the
heating circulation pumps will be
switched off permanently. They will
be switched on for 1 minute every 150
hours to prevent them from becoming
stuck
ATTENTION
For multi-functional domestic hot water tank integration
with solids or solar, pump optimisation must be set to "No".
Access Data access authorisation
The "Fitter" (= Qualified technicians) provides access to
parameters without a password, which otherwise requires
"Customer service" access.
