Heat pump manager (Control and display unit)
Position I: Normal operation
This switch turns on the system. The heat pump and a possible 2nd heat source (6 kW E-heater or boiler),
load- and weather-dependent, are turned on and off - as well as regulated - automatically.
Position 0: OFF
Position II: Emergency-heat operation
This switch directly turns on all circulation pumps and the 2nd heat source (9 kW E-heater or boiler),
bypassing the heat-pump manager. Use this position only if a serious malfunction of the heat pump occurs
(e.g.: a fault in the outdoor module or in the heat-pump manager). This function might also be helpful if heat
is ever required and the outdoor module has not yet been installed or or placed in service.
NOTICE!
Make sure that no weather-driven control
occurs during emergency-heat operation.
Therefore, limit the inlet temperature at the
controller for the electric booster heater or at
the external controller for the boiler to a max-
imum temperature matched to the boiler. (e.g.:
55 °C for floor heating-systems)!
NOTICE!
When the heat pump is switched off (position 0
on the function switch), the heating system is
switched off. There is no frost protection func-
tion.
