CT3451 Programmable Thermostat OWNER'S GUIDE If this control is replacing a control that contains mercury in a sealed tube, do not place your old control in the trash. Dispose of it properly. Contact your local waste management authority for instructions regarding recycling and the proper disposal of an old control. MERCURY NOTICE 1 PREPARE FOR INSTALLATION Programmable Heat and/or Cool Low Voltage (20 to 30 Vac) Thermostat and Wallplate Congratulations on the purchase of your new thermostat! More than 100 years of Honeywell engineering produced this thermostat that can provide you with a more comfortable and convenient living environment. Your new thermostat automatically controls the temperature in your home, keeping you comfortable while saving energy when programmed according to these instructions. Direct questions about this thermostat to our Web site at www.honeywell.com/yourhome or call the customer information line at 1-800-468-1502.

Isolating relay required for zone valves that have a 3-wire thermostat connection. CAUTION Equipment Damage Hazard. Handling wires during installation can damage equipment. Disconnect power at furnace or main breaker/ fuse box before beginning installation. Replacing Clock WIth C or C1 Clock Terminals If you are replacing a Honeywell Chronotherm® Thermostat, you may find one or two wires that go to the C or C1 clock terminals on the Chronotherm® Thermostat wiring wallplate. Do not allow them to touch, or you can damage your transformer. Disconnect the wires and wrap them separately using electrical tape; do not wrap them together. Do not place the wires where they can interfere with the new thermostat operation. Record the colors and terminal designation labels of the remaining wires. Carefully unpack your new thermostat and wallplate and save package of screws, instructions and receipt. Remove the cover from the old thermostat. If it does not snap off when pulled firmly from the bottom, check for screw that locks on the cover. Loosen screws holding thermostat to subbase, wallplate or wall and lift away. Disconnect wires from old thermostat or subbase. As you disconnect each wire, use the wiring labels (enclosed) to label each wire with the old terminal designation. If there are only two wires, they do not require labeling. Wrap wires around a pencil to keep them from falling back into the wall as shown in Fig. 2. WIRES THROUGH WALL OPENING Six or More Thermostat Wires If there are six or more wires connected to the thermostat (excluding clock wires attached to terminals), you probably have a variation of a multistage heat pump or other multistage system. The thermostat is not compatible with these systems, so return the product to your retailer. If you want information about which programmable thermostats work with your system, visit our Web site at www.honeywell.com/yourhome or call the customer information line at 1-800-468-1502. Three Thermostat Wires M5136 Fig. 2. Wrapping wires around pencil. If you have three wires for heating only and can operate the fan using the Fan On switch, this thermostat works with your system. However, some hot water (zoned) heating systems have three thermostat wires. The thermostat works only if a contractor installs an isolating relay on these systems. For details, contact a local heating/cooling contractor. 2 69-1620--1 CT3451 PROGRAMMABLE THERMOSTAT 3 MOUNT WALLPLATE IMPORTANT Level for appearance only. The thermostat functions normally even when not mounted level. Position the wallplate on the wall. Level the wallplate for appearance, if desired.

NOTE: To ensure correct mounting of thermostat, restrict all wiring to the shaded area in the center of the terminals. Loosen the terminal screws and slip each wire beneath its matching terminal. The shape of the terminals permit insertion of straight or wraparound connections. See Fig. 5. Tighten the terminals. M12202A Fig. 3. Mounting wallplate to wall. Remove the wallplate from the wall and drill two 3/16in. holes in the wall (if drywall). For firmer wall material such as plaster or wood, drill 7/32-in. holes. Gently tap provided anchors into the drilled holes until flush with the wall. Reposition the wallplate, pulling wires through the wiring opening. Loosely insert the mounting screws into the holes. Level for appearance only; the thermostat functions correctly even when not level. Tighten the mounting screws. FOR WRAPAROUND, STRIP 7/16 IN. (11 mm) FOR STRAIGHT INSERTION, STRIP 5/16 IN.

If unsure about household wiring procedures, call your local heating and air conditioning contractor. Refer to the labels you placed on wires when you removed your old thermostat. Match the letter of your old thermostat wire with the terminal of the corresponding letter on your new thermostat. Refer to Fig. 4. Fig. 5. CT3451 methods for wiring connection. Plug the hole in the wall with insulation to help prevent drafts from adversely affecting thermostat operation. The CT3451 Thermostat is powered with 3AA alkaline batteries and is adaptable to most 18 to 30 Vac heatingcooling systems.
