T4_AHS_ON is the outdoor air temperature for starting the
additional heating source . When the outdoor air temperature
rises above T4_AHS_ ON, the additional heating source will
be unavailable . The relationship between the operation of ad-
ditional heating source and outdoor air temperature is shown
in the picture below:
dT1_AHS_ON is the temperature difference between T1S
and T1 for turning the additional heating source on(only when
T1<T1S-dT1_AHS_ON), dT1_AHS_OFF is the temperature
difference between T1S and T1 for turning the additional he-
ating source off (when T1≥T1S+dT1_AHS_OFF the additio-
nal heating source will turn off), t_AHS_DELAY is the time
that the compressor has run before starting the additional
heating source . It should be shorter than the additional hea-
ting source start time interval .The operation of the heat pump
and the additional heating source is shown below:
If solar energy kit is installed, please select YES at “7 .3 SOLAR ENERGY”, then the solar pump will operate when the solar
energy kit operating for domestic hot water heating, and the heat pump will stop operating for domestic hot water heating .
