If in doubt about whether your wiring is millivolt, line, or low
voltage, have it inspected by a qualified heating and air
conditioning contractor, electrician, or someone familiar
with basic electricity and wiring.
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 compo-
nents 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 short out terminals on gas valve or pri-
mary control to test. Short or incorrect wiring will
burn out heat anticipator and could cause per-
sonal injury and/or property damage.
Do not use on circuits exceeding 30 volts. Higher
voltage will damage control and could cause
shock or fire hazard.
