Thermostat Installation

Installation • 5

To fix the baseplate on a wall, pass the wires through the opening of the baseplate, 

and use either 2x self-taping screws and dry-wall anchors, or regular 6-32 machine 

screws to attach on a standard single-gang electrical junction box (2” x 4”).

2.3.3. Wires and Electrical Connection

Once the baseplate is affixed on the wall, proceed with the wiring connections to the 

terminal block. Please refer to 

Section 2.4., Wiring and Connections

 for 

configuration and signals definition.

CAUTION! Do not over-tighten the screws when attaching the baseplate on a wall as 

physical damage may occur.

CAUTION! Keep the thermostat housing and vents clean and free of any debris to avoid 

malfunction of the device.
