!CAUTION

To prevent electrical shock and/or equipment damage, disconnect electrical power to system, at main fuse or circuit breaker, until installation is complete.

!FAN CAUTION

To prevent personal injury and/or equipment dam- age, check equipment manufacturer’s wiring of fan relay circuit when in EMER HEAT. When the thermostat system switch is in the EMER HEAT position, the thermostat DOES NOT energize the fan relay when the fan switch is in the AUTO position.

NOTE

This typical wiring diagram shows only the terminal iden- tification and wiring hookup. Always refer to wiring instructions provided by equipment manufacturer for sys- tem hookup.

All wiring should be installed in accordance with local and national codes and ordinances.
