Installation

Tip: Before installing the power unit, it is highly recommended the labeled

wires be connected to the terminals snugly according to the thermostat

terminal designations (you may also refer to the picture taken in Step3). Do not

overtighten.

NOTICE! a) The following illustration is for reference, which may be different

from the wiring for your application. b) The thermostat only works with low-

voltage wires (AC 24 V), so it is very important to make sure that the

thermostat is not connected to high-voltage wires.

8. Attach the front module horizontally, making sure that each side of the front

module fully aligns with that of the power unit, and then press the corners following

the order described in the following illustration until you hear a click sound. Note

that you need to discharge the static electricity on your body before mounting the

front module. For example, touching the wall could help on Electro-Static

discharge (ESD).

9. Switch on power to the heating/cooling system. The thermostat should be

powered up as well.

See Mounting instructions for more information.
