• All wiring must conform to local codes and ordinances.

• This thermostat is designed for use with 24 volt AC and

millivolt systems (with a separate 24VAC power adapter).

• The thermostat relay load should be limited to 1.0 amp;

higher amperage may cause damage to the thermostat.

To avoid electrical shock and to prevent damage to the

furnace, air conditioner, and thermostat, disconnect the power

supply before beginning work. This can be done at the circuit

breaker, or at the HVAC system.
