If you add the backup heater in the system, the backup heater
can increase the heating capacity during cold outdoor
temperatures. The backup heater also serves as a backup in
case of malfunctioning and for freeze protection of the outside
water piping during winter time. The capacity of backup heater
for different units is listed below.

① Heat pump capacity.
② Required heating capacity (site dependent).
③ Additional heating capacity provided by backup heater.
The unit have a freeze prevention function that uses the heat
pump to keep the water system safe from freezing in all
conditions. Since a power failure may happen when the unit is
unattended, It's suggested to use anti-freezing flow switch in
the water system. (Refer to 9.4 Water piping).
