Hisense AHM-080HCDSAA - Boiler Operation During SWP

256
Control function
(7) Boiler Operation during Space cooling.
It is possible to operate Space cooling (heat pump and WP1) and DHW (WP3 or boiler) simultaneously when hydraulic
separator is available (refer to 10.2.5), [DSW5-2] set as [OFF ] and [Point of DHW & SWP] set as [After Hydr S] (refer to
10.1), in this situation cooling water circulation will not pass through hydraulic separator.
Boiler can works to meet DHW demand When average outdoor ambient temperature is more than 38°C-40°C , that is out
of heat pump heating operation range , and DHW Electric Heater is inactivated ([DHW_hts] set as [Disabled] , referring to
10.3.3) .

● Boiler ON conditions
Water temperature in the tank [TDHW] is less than [TDHWS]- [DHW_ht_di󰀨] °C and Hot water temperature [Tow3] of the
hydraulic separator is less than Boiler Target temperature -5°C.
[DHW_ht_di󰀨] refers to 10.3.3.
● Boiler OFF conditions
[TDHW] is higher than [TDHWS] or [Tow3] is higher than Boiler Target +5 °C.
10.6.4 Boiler Operation during SWP
The conguration of this option should be done through the master controller.

It is possible to use boiler to heat up SWP when [SWP_B] set as [Enabled]. And [Point of DHW & SWP] should set as [After
Hydr S] to use boiler to heat up SWP. Refer to 10.1.
(1) Boiler will only be enabled when average outdoor ambient temperature is more than 38°C-40°C , that is out of heat pump
heating operation range.
(2) Boiler Target temperature
Boiler Target temperature equals Target outlet water temperature of SWP- [kscob] °C.
Target outlet water temperature of SWP refers to 10.4.2.
(3) Boiler actual output refers to 10.6.1.
(4) Boiler Operation during special operation.
Boiler Operation during SWP Emergency operation (referring to 10.1.3.2) and HP Block operation (referring to10.9.5) as
following.
Boiler will work to o󰀨er immediate heating capacity. And Boiler Target temperature varies 60-65°C.
