Installation Of The Temperature Sensors - Gree GMV-N12U/C-T(U) Owner's Manual

AHU-KIT
.............................Protective earth (screw)
2................................High gear of fan
3................................Middle gear of fan
4................................Low gear of fan
D1/D2........................Communication wires
H1/H2........................Wired controller
① The 2, 3, 4 of fan gear lines are shorted by the factory default.
② Neutral line of fan connects to the N(1).
③ It can be connected to any of them (2, 3, 4) when there is only one gear.
④ Disconnect the short cable between 2 and 3 when there are two gears, then connect the high gear cable to 2,
and connect low gear cable to either 3 or 4.
⑤ When there are three gears, disconnect the short cables between 2 and 3, 3 and 4, then connect the high gear
cable, middle gear cable and low gear cable to 2,3,4 for each.
⑥ Pull the wires inside through the screw nut and close the nut firmly in order to ensure a good pull relieve and
water protection.
⑦ Put through the wires to the coil, tighten the coil while maintaining loose condition of wires to ensure it is not
closely tied up and is waterproof.
⑧ Wiring connection of XT4 and XT5 refer to the following contents.
4.5.2 Wire connection of multiple AHU-KIT control parts
When multiple AHU-KITs control an air handling unit, connect fan control wire and external
signal feedback signal wire of air handling unit to any one AHU-KIT. Please refer to the wiring
method of AHU-KIT for the connection method.

4.6 Installation of the Temperature Sensors

4.6.1 Refrigerant Temperature Sensors
Location of the temperature sensor: A correct installation of the temperature sensors is
required to ensure a good operation.
(1) Inlet pipe temperature sensor (Liquid Temperature sensor)
Install the IN temperature sensor after the distributor and on the coldest temperature pipe of a
heat exchanger.
(2) Outlet pipe temperature sensor (gas Temperature sensor)
Install the OUT temperature sensor 200mm(7-7/8 inch) after the outlet of the heat exchanger.
