INSTALLATION
Commissioning
At a brine inlet temperature of < 10 °C, a regeneration of the heat
source system can be implemented in conjunction with the ex-
tractor module and ethylene glycol or propylene glycol as brine.
Settings enable the determination of the run-on time of
the brine pump, after the heat pump has been shut down.
The values stated correspond to the run-on time in minutes at an
average brine inlet temperature of 0 °C.
Setting Brine pump run-on time
EXTRACT MODULE 0 1 minute
EXTRACT MODULE 30 30 minutes
EXTRACT MODULE 60 60 minutes
EXTRACT MODULE 120 120 minutes
EXTRACT MODULE 180 180 minutes
If the brine inlet temperature rises, the resulting run-on time of the
source pump reduces accordingly. If the brine inlet temperature
drops, the run-on time increases. From a brine inlet temperature
of 10 °C, the run-on time will always be at least one minute.
Note
The heat pump can only be operated as a ground source
heat pump.
13.3.4 Heating
Control dynamic
Setting range 0 to 30
The selected control dynamic is a measure of the switching inter-
val between the compressor and the electric emergency/booster
heater. Normally, the pre-selected dynamic should be sufficiently
fast and without oscillation. Heating systems that respond quickly
require a lower value, whilst very slow responding systems re-
quire the setting of a higher value.
HP sensor max
Maximum high pressure
Setting range 38 bar to 40 bar.
This setting limits the high pressure during DHW or central heat-
ing. The system implements a controlled shutdown when the
maximum high pressure is reached.
See also DHW learning function.
Heating circuit pump rating
Here you set the "Rated heating flow rate" (see chapter "Specifi-
cation / Data table").
13.3.5 DHW
DHW circuit pump rating
Set the maximum flow rate here. If this is noisy, reduce the flow
rate.
13.3.6 Compressor
Idle time
After a heat pump has been shut down, an idle time is set as
protection for the compressor. The default idle time of 20 minutes
should normally not be reduced. Where a reduction is required
because of adjustments or repair work, reset the idle time again
to 20 minutes after completing the necessary work.
Single phase operation
This parameter must always be set to OFF.
Quick start
During commissioning, you can test the heat pump function by
triggering a heat pump quick start. When this parameter is start-
ed, OFF appears at the bottom of the display. Pressing PRG initiates
a quick start. The respective pumps are switched on after the heat
pump has started. The value 60 is visibly counted down to 0 on
the display; then the display shows ON.
After that, the heat pump and the associated buffer charging pump
are switched ON.
13.3.7 Emergency mode
Characteristics in case of "Fatal Error" conditions in conjunction
with the emergency operation:
The EMERGENCY OPR parameter can be set to ON or OFF.
Emergency mode set to ON:
The program selector automatically changes over to emergency
mode as soon as faults occur and the heat pump fails.
Emergency operation set to OFF:
As soon as faults occur and the heat pump fails, the electric emer-
gency/booster heater takes over the frost protection of the central
heating system. Users can then select emergency mode on their
own initiative.
13.3.8 Heat pump reset
The heat pump can be reset if a fault occurs. Setting it to ON resets
the fault that has occurred. The compressor starts again. The fault
remains stored in the fault list.
13.3.9 Fault list reset
ON / OFF
The entire fault list will be deleted.
13.3.10 SYSTEM RESET
A system reset will reset the heat pump manager to its delivered
condition (factory settings).
You will need to select the corresponding heat pump type
again.
Note
The heat pump can only be operated as a ground source
heat pump.
Heat pump type WPFMFG must be set.
