After wiring, see INSTALLER MENU for proper thermostat configuration. Wiring table shown are for typical systems and describe the thermostat terminal functions. Wiring will change when dedicated emergency heat is on (See Installer Menu #15). Terminal Designations RC RH O/B 6 (not shown) - 3 wire zone valve Y G W/E C L Y2 W2 Terminal Function Power (24V) - Cooling Power (24V) - Heating Reversing Valve or output for 3 wire zone valves Configurable as "O" or "B" Reversing Valve or 3 wire zone heat (power close) 1st Stage Compressor (conventional or heat pump) Fan Relay 1st Stage Heat (conventional); 1st Stage Auxiliary Heat (heat pump) Can operate as Emergency Heat only (See Installer Menu #15) Common wire for 24V (optional with batteries) Heat Pump Malfunction / Diagnostic terminal (input signal requires common) 2nd Stage compressor (conventional only) 2nd Stage Heat (Conventional) Can operate as 1st Stage Auxiliary Heat (See Installer Menu #15) Leveling Thermostat Leveling is for appearance only and will not affect thermostat operation. Precautions · Do not exceed the specification ratings. · All wiring must conform to local and national electrical codes and ordinances. · This control is a precision instrument, and should be handled carefully. Rough handling or distorting components could cause the control to malfunction. ! WARNING Do not use on circuits exceeding specified voltage. Higher voltage will damage control and could cause shock or fire hazard. Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will burn out thermostat and could cause personal injury and/or property damage. ! CAUTION To prevent electrical shock and/or equipment damage, disconnect electrical power to system, at main fuse or circuit breaker box,until installation is complete. ! CAUTION To prevent compressor and/or property damage, if the outdoor temperature is below 50°F, DO NOT operate the cooling system. Do not allow the compressor to run unless the compressor oil heaters have been operational for 6 hours and the system has not been operational for at least 5 minutes. 2 RC/RH Jumper Wire This thermostat electrically connects the RC and RH terminals so a jumper wire is not required. If the application provides a separate wire for RC and RH, clip the RC/RH jumper. This will isolate both terminals so they can be independently used. INSTALLER MENU Battery Location Premium AA alkaline batteries are required when C-wire is not available. When C-wire is available, the batteries provide a back-up source of power (this will maintain the clock in the event of a power outage).
