As long as AC power is continuously available to transformer, the thermostat will be compatible with most control systems. The T8611G,R models include SYSTEM and ENRG SAV LEDs near the top front of the thermostat. The SYSTEM LED lights when the thermostat is signaling for heating or air conditioning. The ENGR SAV LED lights during the LEAVE and SLEEP periods. The AUX. HT., EM. HT., and CHECK LEDS are located near the bottom center of the subbase. See Table 1. The AUX. HT. LED lights whenever the thermostat is calling for operation of the backup or auxiliary heater. Backup (auxiliary) heat is more expensive to operate than the heat pump and typically is used only when the heat pump is unable to handle the load. The EM. HT. LED lights whenever the thermostat system switch is in the EM. HT. position. The CHECK LED lights when something needs to be checked to maintain efficient operation of the system. Consult heat pump equipment literature to determine specific meaning of this LED. Heat and cool anticipation is fixed in all models; no adjustment is necessary. Cycle rates are adjustable for auxiliary heating stage. TABLE 1—Thermostat Models. Thermostat Stages Switching LEDs Changeover Terminals Comments See Fig. Heat Cool System Fan T8611G 2 1 EM.HEATONEM.

Read these instructions carefully. Failure to allow them could damage the product or cause a hazardous condition. 2. Check the ratings on the product to make sure the product is suitable for your application. 3. Installer must be a trained, experienced service technician. 4. Allow thermostat to warm to room temperature before operating. 5. After installation is complete, check out product operation as provided in these instructions. ! CAUTION 1. Disconnect power supply to prevent electrical shock or equipment damage. 2. After wiring is complete, push excess wire back into the hole, and plug hole with nonhardening caulk, putty or insulation to prevent drafts from affecting thermostat operation. LOCATION Install thermostat and subbase 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 J.H. • 3-92 • © Honeywell Inc. 1992 • Form Number 69-0348—1 by— by— cabinets. —hot or cold air from ducts. —radiant heat from sun or appliances —concealed pipes and chimneys. —unheated (uncooled) areas behind the thermostat, such as an outside wall. IF REPLACING AN EXISTING THERMOSTAT Turn off power to thermostat at furnace or heat pump. A two-transformer system may require turning off two switches or disconnects. Remove any existing wallplate or subbase from the wall. Label or write down each wire color with the letter or number on the wiring terminal as the wire is removed, to avoid miswiring later. IF NEW INSTALLATION Run a cable to a hole at the selected wall location, and pull about 3 in. [76 mm] of wire through the opening. Color- coded, 8-gauge thermostat cable with one conductor for each wiring terminal is recommended. Good service practice recommends selecting cable with one or two more conductors than the immediate application requires. MOUNTING SUBBASE The subbase does not require leveling for proper operation, but for appearance only. Remove thermostat from subbase, see Fig. 1. The subbase mounts directly onto the wall with the screws included in the package. Use the subbase as a template, and with a pencil, mark the two mounting screw positions, see Fig. 2. Use 3/16 in. bit to drill holes for anchors. Gently tap anchors into holes until they are flush with the wall surface. Thread wires through the center opening of the subbase. Then mount the subbase using two screws provided. Gently tighten screws level top surface of subbase, then securely tighten screws. Fig. 2—Mounting subbase on wall.

Disconnect power before wiring to prevent electrical shock or equipment damage. The shape of the terminal barrier permits insertion of straight or conventional wraparound wiring connections. Either method is acceptable. Refer to Figs. 4-6 for typical hookups of subbase and thermostat. NOTE: Keep all wiring restricted to ribbed area surrounding terminals to assure thermostat/subbase contact, see Fig. 3. Fig. 1—Removing thermostat from subbase.
