Method C
（Double zone control）
There are three methods for connecting the thermostat cable
(as described in the picture above) and it depends on the
application.

CN16
（Mode set control）
Method A
CN13
CN15
RT can control heating and cooling individually, like the
CN18
controller for 4-pipe FCU. When the indoor unit is connected
with the external temperature controller, user interface FOR
SERVICEMAN set ROOM THERMOSTAT to MODE SET：
CN31
A.1 When unit detect voltage is 12VDC between CL and COM
,the unit operates in the cooling mode.
CN35
A.2 When unit detect voltage is 12VDC between HT and COM,
the unit operates in the heating mode.
CN36
A.3 When unit detect voltage is 0VDC for both side(CL-COM,
HT-COM) the unit stop working for space heating or cooling.
4 5
A.4 When unit detect voltage is 12VDC for both side(CL-COM,
9 10
HT-COM) the unit working in cooling mode.
（One zone control）
Method B
RT provide the switch signal to unit. User interface FOR
SERVICEMAN set ROOM THERMOSTAT to ONE ZONE：
B.1 When unit detect voltage is 12VDC between HT and COM,
unit turns on.
B.2 When unit detect voltage is 0VDC between HT and COM,
unit turns off.
（Double zone control）
Method C
IN
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 12VDC between HT and COM
,zone1 turn on.When unit detect voltage is 0VDC between HT
and COM, zone1 turn off.
