FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
This wall-mounted, low voltage thermostat maintains
room temperature by controlling the operation of heating
systems. The user may program up to four time/temperature settings per 24 hour period. The thermostat stores
independent heating programs for 5-day (weekday) and
2-day (weekend) periods. Three "AA" Energizer® batteries will maintain the stored program for approximately
one year, if incoming power should fail. If power failure is
extensive and the program is lost, after power restoration,
the thermostat will automatically maintain a factory
preprogrammed heating temperature of 64°F.

INSTALLATION INSTRUCTIONS
DESCRIPTION
If in doubt about whether your wiring is millivolt, line, or low
voltage, have it inspected by a qualified heating and air
conditioning contractor, electrician, or someone familiar
with basic electricity and wiring.

PRECAUTIONS
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.
To prevent electrical shock and/or equipment
damage, disconnect electric power to system, at
main fuse or circuit breaker box, until installation
is complete.
Do not use on circuits exceeding specified voltage. Higher voltage will damage control and
could cause shock or fire hazard.
Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will
burn out thermostat and could cause personal
injury and/or property damage.

INSTALLATION
NEW INSTALLATION
You should program the thermostat with batteries
installed before attaching on subbase. See OPERATION GUIDE for programming instructions.
SELECT THERMOSTAT LOCATION
Proper location insures that the thermostat will provide a
comfortable building temperature. Observe the following
general rules when selecting a location:
1. Locate thermostat about 5 ft. above the floor.
2. Install thermostat on a partitioning wall, not on an
outside wall.
3. Never expose thermostat to direct light from lamps,
sun, fireplaces or any temperature radiating equipment.
4. Avoid locations close to windows, adjoining outside
walls, or doors that lead outside.
5. Avoid locations close to air registers or in the direct
path of air from them.
6. Make sure there are no pipes or duct work in that part
of the wall chosen for the thermostat location.
7. Never locate thermostat in a room that normally
warmer or cooler than the rest of the building.
8. Avoid locations with poor air circulation, such as
behind doors or in alcoves.
APPLICATIONS
For use with:
• Standard two-wire heat-only systems
• Gas or oil fired systems
• Millivolt systems
• 3-wire zone valve systems
Do not use with:
• Multi-stage systems
• Heat pump systems
• Systems exceeding 30v AC and 1.5 Amps

1. Probe for obstructions in partition before drilling 1/2"
hole in wall at selected location. Take up quarter
round and drill a small guide hole for sighting (see fig.
1). From basement, drill 3/4" hole in partition floor
next to guide hole. In basementless buildings, drill
1/2" hole through ceiling and into partition from above.
2. Through this hole drop a light chain, or 6" chain
attached to a strong cord. Snag cord in basement
with hooked wire. In basementless buildings, drop
cord through hole in ceiling and down partitioning;
snag cord at the thermostat location.
3. Attach thermostat wire to cord and pull wire through
hole in wall so that 6" of wire protrudes.
