a) Procedure
Connect the cable to the appropriate terminals as shown in the picture.
Fix the cable reliably.
6) 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 connect method depend on
the room thermostat type.
Room thermostat type 1 (High voltage):

There are three methods for connecting the thermostat cable (as described in the
picture above) and it depends on the application.
（Mode set control）
Method A
RT can control heating and cooling individually, like the controller for 4-pipe FCU. When
the hydraulic module is 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, H-L1) 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 230VAC between H and L1, unit turns on.
B.2 When unit detect voltage is 0VAC between H and L1, unit turns off.
