10.1.3 Heat source
Basically, Heat pump produces capacity for space heating / space cooling / domestic hot water / swimming pool by
transforming renewable energy from the outside air into heat. Air to water heat pumps extract the free energy present in the
air, which is e󰀩cient to heat a home up to a comfortable temperature.
10.1.3.1
Available heat source
Besides heat pump several other complementary heat sources can be incorporated in the heat pump system to o󰀨er
complementary heat to extend the application.
(1) Auxiliary electric heater
It can be used as complementary heat source for space heating and swimming pool.
(2) DHW electric heater
It can be used as complementary heat source for DHW.
(3) solar panel
It can be used as complementary heat source for DHW.
(4) gas boiler
It can be used as complementary heat source for space heating / DHW / swimming pool.
The decision as to how to operate complementary heat sources is based on ambient temperature and heat source selection
as below.
The conguration of this option should be done through the master controller.

10.1.3.2
Emergency operation
In the event of outdoor unit failure, the required heating can be provided by complementary heat sources such as Auxiliary
electric heater/ DHW electric heater / boiler / solar panel / gas boiler. The unit can operate to o󰀨er heating capacity
intentionally as emergency operation for space heating / DHW / SWP without outdoor unit function.
Note:
1.[Point of DHW & SWP] should set as [After Hydr S] to use boiler to heat up DHW/SWP during Emergency operation and [HP
Block]. Refer to 10.1. and 10.9.5.
The conguration of this option should be done through the master controller.
