This thermostat is intended for use with a low voltage system; do
not use this thermostat with a line voltage system. If in doubt
about whether your wiring is millivolt, line, or low voltage, have
it inspected by a qualified heating and air conditioning contractor
or electrician.
Do not exceed the specification ratings.
All wiring must conform to local and national electrical codes and
ordinances.
This control is a precision instrument, and should be handled
carefully. Rough handling or distorting components could cause
the control to malfunction.

This thermostat is configured from the factory to operate a heat/
cool, fossil fuel (gas, oil, etc.), forced air system. It is configured
correctly for any system that DOES NOT require the thermostat
to energize the fan on a call for heat. If your system is an electric
heat or heat-pump system that REQUIRES the thermostat to
turn on the fan on a call for heat, locate the
switch switch

1. Remove the packing material from the thermostat. Gently
pull the cover straight off the base. Forcing or prying on the
thermostat will cause damage to the unit. If necessary, move
the electric heat switch (see
above).
2. Connect wires beneath terminal screws on base using
appropriate wiring schematic (see figs. 2 through 7).
3. Place base over hole in wall and mark mounting hole
locations on wall using base as a template.
4. Move base out of the way. Drill mounting holes.
5. Fasten base loosely to wall, as shown in fig. 1, using two
mounting screws. Place a level against bottom of base,
adjust until level, and then tighten screws. (Leveling is for
appearance only and will not affect thermostat operation.) If
you are using existing mounting holes, or if holes drilled are
too large and do not allow you to tighten base snugly, use
plastic screw anchors to secure subbase.
