INSTALLATION CONSIDERATIONS
The thermostat is a wall mounted, low-voltage thermostat,
which maintains room temperature by controlling the opera-
tion of a heating and air conditioning system. Batteries are
not required; temperature and mode settings are preserved
with the power off.
I. THERMOSTAT LOCATION
Thermostat should be mounted:
- Approximately 5 ft. (1.5m) from fl oor.
- Close to or in a frequently used room, preferably on an
inside partitioning wall.
- On a section of wall without pipes or duct work.
Thermostat should NOT be mounted:
- Close to a window, on an outside wall, or next to a door
leading to the outside.
- Exposed to direct light and heat from a lamp, sun,
fi replace, or other temperature-radiating object which
may cause a false reading.
- Close to or in direct airfl ow from supply registers and
return-air grilles.
- In areas with poor air circulation, (behind a door or in
an alcove.)
II. INSTALL THERMOSTAT
1. Turn off all power to unit.
2. If an existing thermostat is being replaced:
A. Remove existing thermostat from wall.
B. Disconnect wires from existing thermostat, one at
a time. Be careful not to allow wires to fall back into
the wall.
C. As each wire is disconnected, record wire color and
terminal marking.
D. Discard or recycle old thermostat.
NOTE: Mercury is a hazardous waste and MUST be
disposed of properly.
3. Separate the thermostat and back plate.
4. Route thermostat wires through hole in back plate. Level
back plate against wall (for aesthetic value only - thermo-
stat need not be leveled for proper operation) and mark
