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. When the
hydraulic module is connected with the external
temperature controller, user interface set ROOM
THERMOSTAT to MODE SET:
POWER
A.1 When unit detect voltage is 230VAC between
IN
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.
• Method B (One zone control)
RT provide the switch signal to unit. User interface
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
POWER IN
and L1, unit turns off.
