1. The first grade antifreeze
protection condition: when
6°C<T1 water in temperature
<10°C and T5 ambient
temperature 3°C, water pump
should operate 30 minutes, then
stop 30 minutes in this cycle.
When ambient temperature
T5>5°C or T1 water in
temperature 15°C, water pump
stop operating will activate the
antifreeze protection.
2. The second grade antifreeze
protection condition; T1 water in
temperature 6°C and T5 2°C, it
goes into the second antifreeze
protection, the heat pump
should go into Smart mode for
water heating will to T1>15°C or
T5>7°C.
Remarks: The water pump and heat
pump must be turned ON or in
standby status.
