B.1 When unit detect voltage is 230VAC between H and N, unit turn on.
B.2 When unit detect voltage is 0VAC between H and N, unit turn off.
When ROOM THERMOSTAT is set to YES, the indoor temperature sensor Ta can't be set to valid, unit running only
according to T1.
Method C
Hydraulic module is connected with two external temperature controllers, while user interface FOR SERVICEMAN set DUAL
ROOM THERMOSTAT to YES:
C.1 When unit detect voltage is 230VAC between H and N ,the MAIN side turn on.When unit detect voltage is 0VAC between
H and N, the MAIN side turn off.
C.2 When unit detect voltage is 230VAC between C and N, the ROOM side turn on according to climate temp curve. When unit
detect voltage is 0V between C and N, the ROOM side turn off.
C.3 When H-N and C-N are detected as 0VAC, unit turn off.
C.4 when H-N and C-N are detected as 230VAC, both MAIN and ROOM side turn on.
The wiring of the thermostat should correspond to the settings of the user interface. Refer to 10.7 Field setting/Room
Thermostat.
Power supply of machine and room thermostat must be connected to the same Neutral Line and (L2) Phase Line(for
3-phase unit only).
