This thermostat is intended for use with a low voltage NEC Class II system. Do not use this thermostat with a line voltage system. If in doubt about whether your wiring is millivolt, line, or low voltage, have it inspected by a qualified heating and air conditioning contractor or electrician.
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.
▲! CAUTION
To prevent electrical shock and/or equipment dam- age, disconnect electric power to system at main fuse or circuit breaker box until installation is complete.
PRECAUTIONS
▲! 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 damage thermostat and could cause personal injury and/or property damage.
Thermostat installation and all components of the system shall conform to Class II (current limited) circuits per the NEC code. Failure to do so could cause a fire hazard.
