This thermostat is intended for use with a 24-volt system; do not
use this thermostat with a millivolt or 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.
To prevent electrical shock and/or equipment damage
disconnect electric power to system at main fuse or
circuit breaker box until installation is complete.
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.
