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.
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.
