7.6.12 For room thermostat:
Room thermostat type 1(High voltage): "POWER IN"
provide the working voltage to the RT, doesn't provide the
voltage to the RT connector directly. Port "15 L1" provide the
220V voltage to the RT connector. Port "15 L1" connect from
the unit main power supply port L of 1- phase power supply.
Room thermostat type 2(Low voltage) : "POWER IN"
provide the working voltage to the RT
NOTE
There are two optional connecting methods
depending on the room thermostat type.

There are three methods for connecting the thermostat
cable (as described in the picture above) and it depends
on the application.
Method A
（Mode set control）
RT can control heating and cooling individually, like the
controller for 4-pipe FCU.
connected with the external temperature controller, user
interface FOR SERVICEMAN set ROOM THERMOSTAT to
MODE SET：
A.1 When unit detect voltage is 230VAC between C and L1 ,the
unit operates in the cooling mode.
A.2 When unit detect voltage is 230VAC between H and L1, the
unit operates in the heating mode.
A.3 When unit detect voltage is 0VAC for both side(C-L1, H-L1)
the unit stop working for space heating or cooling.
A. 4 When unit detect voltage is 230VAC for both side(C-L1, L1)
H- the unit working in cooling mode.
Method B
（One zone control）
RT provide the switch signal to unit. User interface FOR
SERVICEMAN set ROOM THERMOSTAT to ONE ZONE：
B.1 When unit detect voltage is 230VAC between H and L1, unit
turns on.
B.2 When unit detect voltage is 0VAC between H and L1, unit
turns off.
Method C
（Double zone control）
Indoor unit is connected with two room thermostat, while
user interface FOR SERVICEMAN set ROOM THERMOSTAT
to DOUBLE ZONE:
C.1 When unit detect voltage is 230VAC between H and
L1 ,zone1 turns on.When unit detect voltage is 0VAC between
H and L1, zone1 turns off.
C.2 When unit detect voltage is 230VAC between C and L1,
zone2 turns on according to climate temp curve. When
unit detect voltage is 0V between C and L1, zone2 turns off.
C.3 When H-L1 and C-L1 are detected as 0VAC, unit turns off.
C.4 when H-L1 and C-L1 are detected as 230VAC, both zone1
and zone2 turn on.
