PRECAUTIONS

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 famil-
iar 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 use on circuits exceeding 30 volts. Higher
voltage will damage control and could cause shock
or fire hazard.

DO NOT USE this thermostat on heat pump sys-
tems that have a spark ignition gas or fossil fuel
second stage heat source.
