reduced to a minimum and the heating circulation
pumps switched off. If the mean temperature falls
below the set heating limit, heating mode is resumed
automatically.
Parall. operation Parallel operation
No = default setting, 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 heating commands from the master HP
page 67, Program area “Parallelconnection”
Pump optim. Time Pump optimisation Time
If the pump optimisation is switched on (pump op-
timisation YES), the time be dened, according to
which the heating circulation pumps are switched
off.
If the heat pump is off during this time because
there is no need for heating, the pump will loop -
30 minutes off, 5 minutes on, until there is a further
heating requirement.
Remote maintenance
Yes = Remote maintenance function switched on
No = Remote maintenance function switched off
For further details regarding the use of the remote
maintenance function, see page 63, „Remote
maintenance“
time pump ow Feed VBO
Feed-time for the heat-source pump in brine/water
or water/water appliances can be set here. This
may be necessary if the time from switching on the
pump until the nominal rate of ow is reached is
greater than 30 seconds.
min defrost cycle Defrost cycle time,
minimum timebetween two defrost processes
Option only available on L/W appliances
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 difference between the return ow set and
actual values is greater than the setting “hysteresis
HR verk (“Temperature settings”), then the second
compressor stage cuts in after this time.
NOTICE
A compressor may not cut in more than three times
per hour. If this gure has already been reached, cut-
ting in will take longer!
ATTENTION
Only switch on compression monitoring for error
locating during maintenance work.
In the case of devices with a power supply monitor,
the compressor monitoring is switched off in the
factory setting.
Setting hc Control of the heating curves
Set. AT = ow setpoint temperature of the heating is
calculated via a set heating curve
Fixed Tp = ow setpoint temperature can be se-
lected independently of the external temperature
specication
Setting mc 1 Setting mixing circle 1
Set. AT = return setpoint temperature of the heating
is calculated via a set heating curve
Fixed Tp = return ow setpoint temperature can be
selected independently of the external temperature
specication
Screed heating
Option only possible for external energy source
(wood boiler, solar system with parallel tank,…)
w. mixer = If the mixer is dened as a discharge
mixer, it controls according to the setpoint temper-
ature in the screed heating program
wo. mixer = If the mixer is dened as a discharge
mixer, it always starts up during the screed heating
program
El. Anode Electrical anode
Impressed current anode in the domestic hot water
tank
Yes = Impressed current anode present
No = Impressed current anode not present
ATTENTION
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 instructions of the rel-
evant heat pump.
Heating limit
If the heating limit parameter is set to yes, the heat-
ing will automatically be switched off to summer
mode and vice versa.
If the heating limit is enabled, the daily mean
temperature will be displayed under Service-Infor-
mation-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
