4. Disconnect all the labeled wires and then remove the old thermostat.
NOTICE! Do not discard the old thermostat in the trash if it contains mercury.
Contact a thermostat recycling organization, for example, www.thermostat-
recycle.org, for safe disposal of the old thermostat.
5. Check whether more wires are needed to bring AC 24 V power from the HVAC
equipment to the thermostat. If yes, prepare the wires and label them accordingly.
6. Seal the conduit and/or wall opening to prevent entrance of cold or warm air and
ensure accurate temperature readings by the internal sensor.
7. Install the mounting plate and power unit.
– If you are mounting the thermostat directly on a wall, screw the small mounting
plate enclosed with the thermostat snugly on the wall using a screwdriver,
making sure that the mounting plate is placed correctly (the part with the
upward arrow is placed on the top), and then screw the power unit on the
mounting plate.
– If you are mounting the thermostat on a conduit box, install the metal mounting
plate enclosed with the thermostat tightly on the conduit box (making sure that
the upward arrow part is placed on the top), attach the plastic trim plate to the
mounting plate, and secure by screws.
