（Double zone control）
Method C
Hydraulic Module 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.

（Double zone control）
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

,the unit operates in the cooling mode.
A.2 When unit detect voltage is 12VDC between HT and COM,
the unit operates in the heating mode.
CN31
A.3 When unit detect voltage is 0VDC for both side(CL-COM,
HT-COM) the unit stop working for space heating or cooling.

unit turns on.
B.2 When unit detect voltage is 0VDC between HT and COM,
