Defrost cycle time, minimum timebe-
tween two defrost processes
Take the time to be set from the instructions for use for the
respective L/W appliance.
time 2.CP short
Shortening second compressor stage
Time before the second compressor stage cuts in. If the
dierence between the return ow set and actual values
is greater than the setting “Hysteresis 2.CP short”, then the
second compressor stage cuts in after this time.
NOTE
A compressor may not switch on in more than three times
per hour. If this gure has already been reached, cutting in
is postponed.

Freig. ZWE HZ
Duration until the additional heat
generator is released in heating mode
Freig. ZWE WW
Duration until the additional heat
generator is released in domestic hot
water preparation
The additional heat generator is activated immediately (time
setting = 0) or after the set time has elapsed in order to
support the heat pump in domestic hot water preparation
and to reach the desired domestic hot water temperature as
quickly as possible.

El. Anode
Electrical anode
Impressed current anode in the domestic hot water tank
Yes Impressed current anode present
No Impressed current anode not present
IMPORTANT
In the case of devices with an impressed current anode
tank, “Yes“ must be set in this menu eld in order to ensure
the corrosion protection of the tank.
The impressed current anode must be connected according
to the operating manual of the relevant heat pump.
Heating limit
Switching on / o of the heating limit
Yes heating limit enabled
No heating limit switched o
If the heating limit parameter is set to yes, the heating will
automatically be switched o to summer mode and vice
versa.
If the heating limit is enabled, the daily mean temperature
will be displayed under Service> Informations>
Temperatures. At the same time, the heating menu will
contain the menu item heating limit. You can use this menu
item to set the temperature from which the heat pump is not
supposed to provide any more heat. If the mean temperature
exceeds the value set here, the return setpoint temperatures
are reduced to a minimum and the heating circulation pumps
switched o. If the mean temperature falls below the set
heating limit, heating mode is resumed automatically.
parall. operation
Combination of up to 4 heat pumps
No heat pump works independently
Master heat pump is the parallel connection
master and takes over the heat control
of the system
Slave heat pump is part of a parallel
connection and receives commands
from the master HP for heating and
domestic hot water preparation

pump optim. Time
If the pump optimisation is switched on (Pump opt.=
Yes), the time be dened, according to which the heating
circulation pumps are switched o.
If the heat pump is o during this time because there is
no need for heating, the pump will loop - 30 minutes o, 5
minutes on, until there is a further heating requirement.
