Type of Heating System to be Controlled Conditions/Compatibility Electric (Line Voltage)— typical baseboard and radiant •The R8239D1015 Isolating Relay or R841 Silent Switching Center must be installed in the thermostat control circuit.a Fan Coil Unit • Compatible. Assure correct subbase identity is selected for fan control. Gas—Direct Spark Ignition (DSI), Intermittent Pilot (IP), and Standing Pilot (SP) •Compatible. If not using battery backup, assure that 24V control transformer common is accessible for connection to thermostat cable conductor and power to the transformer is not regularly interrupted by high temperature or limit operation. Heat Pump • Compatible. Assure correct subbase identity is selected for fan control and changeover control (O terminal for cool and B terminal for heat). Hot Water Zone • Honeywell 2-wire valves are compatible. • Some non-Honeywell 2-wire valves require an R8239D1015 Isolating Relay in the thermostat control circuit.a • Some 3-wire valves require an R8239A1052 Isolating Relay in the thermostat control circuit.a, b Oil • If not using battery backup, assure that the 24V control transformer common is accessible for connection to thermostat cable conductor and power to transformer is not regularly interrupted by high temperature, purge cycle, or limit operation. Vent Damper • Honeywell damper motors are compatible. • Some non-Honeywell damper motors require an R8239D1015 Isolating Relay in the thermostat control circuit.a Check control amperage requirement. Warm Air Zone • Most are compatible. a If thermostat is not compatible with the system being controlled, the system will not operate. No hazard exists. The thermostat will not be damaged unless it is used to directly control a line voltage system. For proper system operation, a Honeywell R841 or R8239D1015 Isolating Relay must be added to the thermostat control circuit. b Consult manufacturer for installation requirements. D.F. • Rev. 11-94 • M3375 • ©Honeywell Inc. 1994 • Form Number 69-0638—1 Installation Installation WHEN INSTALLING THIS PRODUCT… 1. Read these instructions carefully. Failure to follow them could cause a hazardous condition. 2. Installer must be a trained experienced service technician. 3. After installation is complete, check out product operation as provided in these instructions. IMPORTANT: An incorrectly leveled subbase will cause the temperature control to deviate from setpoint. It is not a calibration problem. CAUTION 1. Disconnect power supply to prevent electrical shock or equipment damage. 2. To prevent interference with the thermostat linkage, keep wire length to a minimum and run wires as close as possible to the subbase. 3. Do not overtighten thermostat captive mounting screws because damage to subbase threads can result. 4. Do not short across coil terminals on relay. This can burn out the thermostat heat anticipator. LOCATION Locate thermostat about 5 ft [1.5m] above the floor in an area with good air circulation at average temperature. Do not mount the thermostat where it may 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. Run wires from the heating, cooling or heating/cooling equipment to the new thermostat location. Refer to the Typical Wiring Diagrams section to determine the number of wires required for your application. UNPACK THERMOSTAT Handle your new thermostat carefully; rough handling may interfere with its accuracy. Before unpacking, refer to Fig. 1. Remove and discard the shipping wrap. IMPORTANT: Save package of screws and instructions for the homeowner. Remove the thermost...
