Refer to Table 1 tools required flat bladed screwdriver hand power drill with 3 16 in drill bit wire cutter stripper or knife bubble level or plumb bob and line Order Q682B Subbase separately Notice control contains mercury in a sealed tube Do not control in the trash at the end of its useful life this control is replacing a control that contains mercury a sealed tube do not place your old control in the trash your local waste management authority for in regarding recycling and the proper disposal of this or of an old control containing mercury in a sealed you have questions call Honeywell Inc at 1 800 1 COMPATIBILITY FOR NON BATTERY POWERED THERMOSTATS power is off to the heating cooling or heating system at the main fuse panel Most buildings have separate switch box or circuit breaker for disconnecting to the heating and cooling if applicable equipment thermostat is compatible with all heating cooling or systems when thermostat is powered by If thermostat is not powered by batteries refer to 1 for thermostat and system compatibility information of Heating System to be Controlled Line Voltage baseboard radiant Coil Unit Spark Ignition DSI Pilot IP and Standing SP The R8239D1015 Isolating Relay or R841 Silent Switching Center be installed in the thermostat control circuit a Compatible Assure correct subbase identity is selected for fan Compatible If not using battery backup assure that 24V control common is accessible for connection to thermostat conductor and power to the transformer is not regularly by high temperature or limit operation Compatible Assure correct subbase identity is selected for control and changeover control O terminal for cool and terminal for heat Honeywell 2 wire valves are compatible Some non Honeywell 2 wire valves require an R8239D1015 Relay in the thermostat control circuit a Some 3 wire valves require an R8239A1052 Isolating Relay in the control circuit a b If not using battery backup assure that the 24V control transformer is accessible for connection to thermostat cable conductor power to the transformer is not regularly interrupted by high purge cycle or limit operation Honeywell damper motors are compatible Some non Honeywell damper motors require an R8239D1015 Relay in the thermostat control circuit a Check control requirement Pump Water Zone Damper Air Zone If thermostat is not compatible with the system being controlled the system will not operate No hazard exists The will not be damaged unless it is used to directly control a line voltage system For proper system operation a R841 or R8239D1015 Isolating Relay must be added to the thermostat control circuit Consult manufacturer for installation requirements Most are compatible Rev 12 94 Inc 1994 Form Number 69 0642 and discard the shipping wrap INSTALLING THIS PRODUCT Read these instructions carefully Failure to follow could cause a hazardous condition Installer must be a trained experienced service technician After installation is complete check out product op as provided in these instructions An incorrectly leveled subbase will cause temperature control to deviate from setpoint It is a calibration problem Disconnect power supply to prevent electrical or equipment damage To prevent interference with the thermostat link keep wire length to a minimum and run wires close as possible to the subbase Do not overtighten thermostat captive mounting because damage to subbase threads can result Do not short across coil terminals on relay This burn out the thermostat heat anticipator thermostat about 5 ft 1.5m above the floor in an with good air circulation at average temperature not mount the thermostat where it may be affected by drafts or dead spots behind doors and in corners hot or cold air from
