REMKO CMF 320 Duo - Manual (Page 25)

Control panel
Mode switch
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
2. 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.

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 maximum temperature matched
to the boiler.
(e.g.: 55 °C for floor heating-systems)!
! CAUTION
When the heat pump is switched off (position
0 on the function switch), the heating system is
switched off. There is no frost protection function.
