Sg Ready Control (Optional Pcb) - Panasonic WH-UD05JE5 Service Manual

14.27 SG Ready Control (Optional PCB)

Purpose:

To set ON/OFF of heat pump and target temperature by digital input of third party device if necessary in field.
Remote control setting
For this function, following items need to be set on Remote Control (installer menu) –

SG control = YES or NO

Capacity up setting 1
Heating capacity [50 ~ 150 %]
o
DHW capacity [50 ~ 150 %]
o
Cooling capacity [-15 ~ 0 %]
o

Capacity up setting 2
Heating capacity [50 ~ 150 %]
o
DHW capacity [50 ~ 150 %]
o
Cooling capacity [-15 ~ 0 %]
o
Control contents:
If SG control on remote control = "Yes", then following control only activate by digital input.

While Digital input is " 00 " (Normal operation)
Normal operation. Once detect '00' system will operate back to normal condition.
o
(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)
Heat pump & room heater & tank heater cannot operate.
o
(Solar control and Boiler back up and 2 Zone control can activate.)

While digital input is detected " 10 " (Capacity 1)
Target temperature for heating and DHW Tank is changed according to the percentage set by Remote
o
control setting. However, which setting temperature is change depend on system setting.
Target water temperature of cooling is changed according to the adjustment value set by remocon setting.
o

While digital input is detected " 11 " (Capacity 2)
Target temperature for heating and DHW Tank is changed according to the percentage set by Remote
o
control setting. However, which setting temperature is change depend on system setting.
Target water temperature of cooling is changed according to the adjustment value set by remocon setting.
o

While digital input is detected " 10 " (Capacity 1)
Setting temperature for heating and Tank is changed.
o
However, which setting temperature is change depend on system setting.
If Buffer selection is "YES"
Room side
New Target Buffer tank temperature = Current Target Buffer Tank Temperature * Remote Control setting
(" capacity 1) %
* Max Min regulation is follow Target Buffer tank temperature control specification
** No change of Target zone water temperature, only set higher buffer tank temperature.
