1. Wiring: Connect the cables according to the following wiring drawing

485 communication interface

PROHIBIT

• This product must be installed by a specialized technician. Do not connect cables when the unit is active.
• Do not connect the neutral and live wires to the X/Y/E ends. Otherwise, the wired controller will be burnt.

WARNING

EN

• Check the wiring before powering on the unit. Wrong wiring may damage the wired controller.

1. Insert the cable of the rear cover into the installation box (cassette type). Use pan head screws to fix the rear cover of the wired controller on the installation box (cassette type); connect the flat cable that connects the front and rear PCBs.Use the pipe temperature sensor cable to connect the sensor to the power board.

WARNING

• Do not overtighten the pan head screws, otherwise the rear cover of the wired controller may deform and cannot be levelled on the wall surface, which makes it difficult to install or not securely installed.

EN

1. Buckle the front cover of the wired controller on the rear cover as shown in the following figure.

First buckle the upper ends of the front and rear covers of the wired controller.

Then buckle the lower ends of the front and rear covers of the wired controller.

WARNING

• Make sure that no cables are clamped when buckling the front and rear covers.
• The front and rear covers should be installed correctly. Otherwise, the front and rear covers may get loose and fall apart.
