Remote control setting
For this function, following items need to be set on R/C (installer menu) –
SG control = YES or NO
Capacity up setting 1
o
Heating capacity [50 ~ 150 %]
o
DHW capacity [50 ~ 150 %]
Capacity up setting 2
o
Heating capacity [50 ~ 150 %]
o
DHW capacity [50 ~ 150 %]
Control contents:
If SG control on remote control = "Yes", then following control only activate by digital input.
While Digital input is " 00 " (Normal operation)
o
Normal operation. Once detect '00' system will operate back to normal condition.
(All the target set temperature for heating side and DHW side will return back to previous set temperature
when digital signal change from "10' or"11" back to "00".)
While digital input is detected " 01 " (HP stop)
o
Heat pump & room heater & tank heater cannot operate.
(Solar control and Boiler back up and 2 Zone control can activate.)
While digital input is detected " 10 " (Capacity 1)
o
Target temperature for heating and DHW Tank is changed according to the percentage set by Remote
control setting.
o
Target water temperature of cooling is changed according to the adjustment value set by Remote control
setting.
However, which setting temperature is change depend on system setting.
While digital input is detected " 11 " (Capacity 2)
o
Target temperature for heating and DHW Tank is changed according to the percentage set by Remote
control setting.
o
Target water temperature of cooling is changed according to the adjustment value set by Remote control
setting.
However, which setting temperature is change depend on system setting.
While digital input is detected " 10 " (Capacity 1)
o
Setting temperature for heating and Tank is changed.
However, which setting temperature is change depend on system setting.
