Installation Of Floor Heating Performer (Floor Heating Water Separation Valve) - Gree GMV-S120WL/A-S Service Manual

11.5 Installation of Floor Heating Performer (floor heating water
separation valve)
When connecting floor heating, floor heating performer is recommended to be installed, so
that you can control each room separately in order to save energy. This hydro box is with floor
heating performer interface (single phase 220V), which can be connected with the floor heating
performer. Through setting the linkage between IDU wired controller and floor heating performer,
indoor wired controller can control the startup of floor heating performer in that room. Indoor wired
controller can set the ambient temperature of corresponding room and control the
startup/shutdown of floor heating of that room.
(1) Before installation, please make sure the performer is normally closed type.
(2) The wiring of floor heating water separation valve in the performer is according to the
wiring diagram.
(3) Connect a pressure bypass valve between the performers.
(4) The circulating out of hydro box is connected with floor heating water separator and the
circulating in of hydro box is connected with floor heating water collector.
(5) The corresponding setting relationship between floor heating water separation valve and
IDU:
Notices:
① The corresponding relationship setting must be done in unit off status.
② Only the IDU connected with wired controller and floor heating can be set for
corresponding relationship (linkage). The IDU connected with light board or controlled by
wireless remote controller cannot be set!
Step 1: Confirm the IDU project no. which is in the same room with floor heating and the
corresponding floor heating shunt valve no.:
1) Check the IDU project no. in its wired controller. For example: The IDU project no. in
this room is ―9‖.
2) Check the floor heating shunt valve no. connected with the floor heating in the electric
box of hydro box. For example: The floor heating shunt valve no. is ―floor heating
shunt valve 3‖.
3) Make sure the IDU is in accordance with the floor heating shunt valve. As the
examples above, floor heating shunt valve 3 is in accordance with IDU project no. 9.
