INSTALLING THE DISPLAY UNIT
1. Press the small tab on the bottom center of the display unit with a small screwdriver and
separate the front from the base.
2. Mount the base part on the wall, using suitable screws for the mounting surface.
Ensure the arrow points up.
3. Connect any two wires to the display unit’s terminal block situated on the back. It does not matter
which color goes to which screw terminal.
4. Make a note of the colors of these two wires as you will need to connect the same two wires to
the base unit at the other end.
5. Upon completion of wiring the thermostat, push all excess wiring into the hole in the wall.
If there is a large hole in the wall, plug the hole with suitable filler or foam to ensure an
accurate temperature reading by the
Thermostat
display unit.
6. Engage the upper tabs of the display unit with the counterparts on the base and press the
bottom gently in until you feel it click into place. Do not use excessive force. Ensure you do not
have excessive wire looped inside the enclosure.
NOTE:
Be sure that the
Thermostat
temperature sensor has not been damaged during installation.
