Swimming Pool - Hisense AHM-044HCDSAA Service Handbook

Control function
10.4

Swimming pool

In addition, the unit can be combined with swimming pool. When the swimming pool operation is required, the 3-way valve
for the swimming pool changes its normal position diverting to the swimming pool heat exchanger, allowing to heat the
swimming pool water temperature to a comfortable value.
The configuration of swimming pool availability should be done through the master controller.

Swimming Pool status
NOTE:
1. When swimming pool is available Auxiliary sensor on PCB1 of indoor unit need be configured as function of [Tswp] to
detect swimming pool water temperature. Refer to 10.10.
2. When swimming pool is available Optional Output signal need be configured as function of [3WV SWP] to drive 3-way
valve for the swimming pool.
3. Optional Output signal can be configured as function of [SWP signal] to drive relay of SWP pump. Refer to 10.10.
10.4.1 SWP setting temperature
The operation of this function should be done through the master controller interface of SWP.

10.4.2 SWP Demand ON/OFF and capacity control
There are 2 ways to demand SWP operation:
(1) SWP operation is demanded by request of SWP temperature (the difference of SWP setting temperature and current
SWP temperature.
● SWP operation will start if:
Current SWP temperature[Tswp] is lower than SWP setting temperature[Tswps] -1ºC
● SWP operation will stop if:
Current SWP temperature[Tswp] is higher than SWP setting temperature[Tswps] +2ºC
(2) SWP operation is demanded by request of Optional input signal of [Swimming pool Demand ON/OFF].
● SWP operation will start if:
The corresponding input terminal of [Swimming pool Demand ON/OFF] is closed.
● SWP operation will stop if:
The corresponding input terminal of [Swimming pool Demand ON/OFF] is open.
NOTE:
1. Optional input signal can be configured as function of [Swimming pool Demand ON/OFF] to operate SWP. Refer to
10.10.1.
2. When Optional input signal is be configured as function of [Swimming pool Demand ON/OFF], SWP operation is
demanded by request of Optional input signal of [Swimming pool Demand ON/OFF] instead of by request of SWP
temperature.
When SWP operation is demanded ON the heat pump will be operated to achieve the Target outlet water temperature of
SWP to heat up SWP water.
Target outlet water temperature of SWP =Current SWP temperature+ Offset Temperature [Tswpos].
