Professional Fuel Saver Thermostat
Application
This thermostat provides energy saving control for a
24 Vac gas, oil, or electric heating or heating/cooling
system with independently controlled fan. System switch
positions include HEAT-OFF-COOL: fan switch positions
include ON-AUTO.
Power is supplied for the device by three AA alkaline
batteries (included in package). This allows the thermostat
to be compatible with all control applications.
Heat and cool anticipation is fixed; no adjustment is
necessary. Cycle rates are adjustable for heating.
The current rating is 1.6A maximum up to 30 Vac.
Recycling Notice
If this control is replacing a control that contains mer-
cury in a sealed tube, do not place your old control in the
trash. Contact your local waste management authority for
instructions regarding recycling and the proper disposal of
your old control.
If you have any questions, call Honeywell Inc. at 1-800-

Installation
WHEN INSTALLING THIS PRODUCT…
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazardous
condition.
2. Check the ratings given on the product to make sure
the product is suitable for your application.
3. After installation is complete, check out product
operation as provided in these instructions.
4. Allow thermostat to warm to room temperature
before operating.
CAUTION
Disconnect power supply to prevent electrical
shock or equipment damage.
IMPORTANT: Push excess wire back into the hole, and
plug the hole with non hardening caulk, putty or
insulation to prevent drafts from affecting thermo-
stat operation.
LOCATION
Install thermostat and wallplate about 5 ft. (1.5m)
above the floor in an area with good air circulation at
room temperature.
Do not install the thermostat where it may be affected by:
— drafts or dead spots behind doors, in corners, or under
cabinets.
— hot or cold air from ducts.
— radiant heat from sun or appliances.
— concealed pipes and chimneys.
— unheated (uncooled) areas such as an outside wall,
behind the thermostat.
IF REPLACING AN EXISTING THERMOSTAT
Turn off power to thermostat at furnace or boiler. A two-
transformer system may require turning off two switches or
disconnects. Remove any existing wallplate or subbase
from wall. To avoid miswiring later, label or write down
each wire with the letter or number on the wiring terminal
as the wire is removed.
IF NEW INSTALLATION
Run cable to the hole in the selected wall location, and
pull about 3 in. (76 mm) of wire through the opening.
Color-coded, 18 gauge thermostat cable with at least one
conductor for each wiring terminal is recommended.
MOUNTING WALLPLATE
Remove thermostat from wallplate (Fig. 1).
The wallplate does not require leveling for operation,
but only for appearance. The wallplate mounts directly
onto the wall with the screws included in the package. Use
the wallplate as a template, and with a pencil, mark two
mounting screw positions that best fit the application using
two of the three mounting holes in the wallplate (Fig. 2).
Use 3/16 in. bit to drill holes for anchors. Gently tap
anchors into holes until flush with the wall surface. Thread
wires through the center opening of the wallplate. Then
mount the wallplate using the two screws provided. Gently
tighten screws, level top surface of wallplate, and securely
tighten the screws.
