4. Pipe temperature sensor installation
•Dx-PMV kit is connected to 3
rd
party Dx-Coil as following figure.
•A correct installation of temperature sensor (TC1, TC2, TCJ) is required to ensure a good operation.
• Maximum piping length between Dx-PMV kit to 3
rd
party coil is 16ft.

Dx-Coil Schematic
■Location of temperature sensor and sensor holder installation
Sensor holders MUST be brazed on to the Dx-Coil pope work to ensure reliable temperature sensing.
There are three coil sensors, these are inserted into the sensor holders, and secured with the sensor fix plate.
( Note : Temperature sensor is packed in Dx-Controller (TCB-IFDA1GUL / TCB-IFDD1GUL) )
TC1 : Ø4mm
(Sleeve colour : Blue)
: Install the temperature sensor at the outlet of the heat
exchanger as close as possible to the heat exchanger.
TC2 : Ø6mm
(Sleeve colour : Black)
: Install the temperature sensor between the distributor
and PMV.
TCJ : Ø6mm
(Sleeve colour : Red)
: Install the temperature sensor hehind of the distributor
on the lowest circuit of the heat exchanger
Pipe size of gas and liquid side is shown the table below.
To ensure the appropriate temperature detection, sensor
holders should be brazed as follows.
