HEAT PUMP - OUTDOOR
TEMP. FOR BIVALENT
OPERATION MODE
Setting of outdoor temperature for bivalent operation mode of heat
pump and other heat source. Below setted temperature the control-
ler makes switchover between heat sources immediately when heat
pump cannot supply requested temperature. Above setted tempe-
rature the controller makes switchover between heat sources on
behalf of temperature deficit i.e. with delay. This principle of
switchover between heat sources provides maximum efficiency and
optimal use of heat pump, even when it solely cannot cover
complete heating demand.

HEAT PUMP - DELAY OF
REPEATED SWITCH-ON
With this setting, we determine the delay time after which the heat
pump can be switched on again. The delay starts when the heat
pump is switched off and until the delay expires, repeated switch-on
of the heat pump will be disabled.
