T8400C, T8401C Electronic Thermostats INSTALLATION INSTRUCTIONS The T8400C and T8401C Thermostats provide singlestage, non-programmable temperature control for 24V heating-cooling systems with manual changeover from heat to cool. Heating cycle rate is selectable at 1, 3, 4, 5, 6, 9, or 12 cph. Cooling cycle rate is fixed at 3 cph. Temperature indication can be set for °F or °C. The T8400C Thermostat is powered through the heating/ cooling system controls. The T8401C requires a common wire for operation. Batteries are not required because setpoints are held permanently by non-volatile memory. The T8400C and T8401C models include a thermostat, wallplate (for wiring and mounting thermostat) and owner's guide. MERCURY NOTICE If this control is replacing a control that contains mercury 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 an old control containing mercury in a sealed tube.

Check the ratings given in the instructions and on the product to make sure the product is suitable for your application. 3. Installer must be a trained, experienced service technician. 4. After installation is complete, check out product operation as provided in these instructions. CAUTION Electrical Shock or Equipment Damage Hazard. Can shock individuals or short equipment circuitry. Disconnect power supply before installation. Location Install the thermostat about 5 ft (1.5m) above the floor in an area with good air circulation at average temperature. See Fig. 1. Do not install the thermostat where it can be affected by: - drafts or dead spots behind doors and in corners. - hot or cold air from ducts. - radiant heat from the sun or appliances. - concealed pipes and chimneys. - unheated (uncooled) areas such as an outside wall behind the thermostat. This thermostat is a precision instrument and was carefully adjusted at the factory. Handle it carefully. Mounting Wallplate to Wall IMPORTANT Level only for appearance. The thermostat functions normally even when not level. Mount the T8400C and T8401C with the screws provided (see Fig. 2) as follows: 1. Place the wallplate at the desired location on the wall. 2. Pull the thermostat wire through the entrance hole on the wallplate. 3. Fasten the wallplate to the wall using the anchors and screws provided. 4. After wiring the wallplate, plug the hole to prevent drafts from affecting the thermostat; see Wiring section. ® U.S. Registered Trademark Copyright © 2004 Honeywell International Inc. • • All Rights Reserved 69-1740
