Honeywell CT1501 Electromechanical Fuel Saver Thermostat Instruction Manual
THERMOSTAT FEATURES
I-Front of thermostat.
Il-Hinged cover lifted.
Ill-Cover removed.
PREPARATION
Thermostat must be mounted on wallplate or subbase included in package to assure operation.
Assemble tools required, as illustrated
If wallplate or subbase is mounted on a vertical outlet box (check old
installation), order 196393A Cover Plate and Adapter Ring (see appropriate
figure under step 4). Call Honeywell Consumer Services (1 -800-468-1 502) for
ordering information, Monday-Friday, 7:30 a.m. to 500 p.m. Central time. Test
to make certain that your heating and cooling systems are working. If either
one does not work, contact your local heatingfair conditioning dealer.
NOTE : Do not operate cooling system if outdoor temperature is below 50′
F [loo C]. Turn off power to the heatingfcooling System at the main fuse
panel.
UNPACK THERMOSTAT
- Remove and discard shipping wrap. Save
- Remove thermostat cover by lifting up from the bottom.
- Carefully remove insert protecting switch 0 bulbs.
- Loosen two captive mounting screws, and 0 separate wallplate or subbase from back of thermostat base.
REMOVE OLD THERMOSTAT
- Remove cover of old thermostat. If the cover 0 doesn’t snap off when pulled firmly from the bottom, check for a screw that locks the cover on.
- Before removing the old thermostat from the 0 wall, look at it carefully to locate the heat anticipator adjustment mechanism. (See illustration to help you recognize the heat anticipator.) Make a note herellof that anticipator setting for future reference. If your thermostat does not have a heat anticipator, do not be concerned. Move on to next paragraph.
- Loosen screws holding thermostat to wallplate, subbase or wall and lift away.
One or two extra wires?
If you are replacing a Honeywell Chronotherm thermostat, you may find one or
two wires that go to the clock terminals on the Chronotherm thermostat wiring
wallplate. Do not allow them to touch, or you may damage your transformer.
Disconnect the wires, and wrap them separately, using electrical tape. Do not
wrap them together. Place the wires where they will not interfere with the
operation of the new thermostat. Record the colors and terminal designation
labels of the rest of the wires.
MOUNT WALLPLATE OR SUBBASE
WIRE WALLPLATE OR SUBBASE
NOTE: All wiring must comply with local electrical Refer to illustration and strip thermostat wire insulation as necessary.
POWER SUPPLY. PROVIDE DISCONNECT MEANS AND Wlll OVERLOAD PROTECTION AS REOUIRED.
- Connect either wire to R terminal and the other wire to W terminal. Firmly tighten screws.
- Push excess wire back into wall, and plug 0 hole In wall with nonflammable Insulation to prevent drafts from affecting thermostat operation.
NOTE: If there are four wires, connect wire marked R to terminal RH and add a jumper wire to connect to RC. If RC is left unconnected, the air conditioner will not turn on. The 4-wire drawing on this page shows how to jumper RC to RH. Strip the insulation off the wire where if connects to the terminals. Firmly tighten screws.
If the labels do not agree with the terminal
- Refer to Table 2 on page 8
- Determine correct hookup from the listed control function and the equipment control circuit
OLDSUBBASE TERMINAL
Push excess wire back into wall. and plug hole in wall with nonflammable
insulation to prevent drafts from affecting thermostat operation.
CONTROL FUNCTION
Heating transformer power to control circuit Cooling transformer power to
control circuit. Heating relay or valve. Cooling relay. Fan relay. Heating
changeover valve or damper control circuit. Cooling changeover valve or damper
control circuit. Heat pump compressor control

For CT1503 750-millivolt heating
Connect either wire to R terminal and the other wire to W terminal. Firmly tighten screws. Push excess wire back into wall, and plug 0 hole in wall with nonflammable insulation to prevent drafts from affecting thermostat operation.
MOUNT THE THERMOSTAT
Do NOT cycle heating system until Step 7 is completed.
SET HEAT ANTICIPATOR LEVER
NOTE: Not applicable on CT1503 millivolt model. The thermostat’s adjustable heat anticipator 0 must be correctly set to accurately control the on-time length of the system. An incorrect setting can result in room temperature swings or burn out the anticipator and void the thermostat warranty. Make sure you have the current draw (anticipator setting) for your system. This is the number you wrote in the box in Step 3 If you were unable to find the current draw for Step 3, this information can be found printed on the primary control at the furnace or boiler. The primary control is usually a gas valve a relay or burner controi box, Aquastat controller or zone valve with the thermostat wires connected to it These controls are usually located behind the furnace cover See next illustration

SET TIMER
clockwise direction. Do NOT reverse the knob. When time is correctly set, the Time Indicator Arrow (see illustration) must point to the correct time and the corresponding daytime (lighr) or nighitime (dark) portion of the program dial.
ATTACH THERMOSTAT COVER
Stat base have been removed. as explained in step 3 Place the two tabs on upper edge of cover into mounting slots in thermostat base Swing cover downward until it engages atch at bottom of base
CHECK OUT THERMOSTAT OPERATION AND SET TEMPERATURE CONTROL b LEVERS
The two levers on top of the thermostat control the low and high temperature for energy savings and comfort control, as shown in illustration
Do NOT check operation by shorting across terminals of relay or valve coil; this will burn out the thermostat heat anticipator, which will void the warranty.
Heating-only System
Turn on power to the furnace. Push both temperaturecontrol leverstogetherat
least 5″ F [3″ C] above room temperature. The heat should comeon.Thefan will
startwhen the furnace heats up. Move both levers5″ F [3″ C] below room
temperature. The heat should shut off. Operate the entire heating system for
at least one complete cycle.
