INSTALLATION AND WIRING

control, then follow his recommendations. If no special
wiring instructions are given, then follow the electrical
connections shown on this diagram for a simple system.

For more complicated systems, especially for hot water
heating, consult the manufacturer of the heating plant for
full details of the desired sequence of control operation.

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 volt-
ages. Higher voltages will damage control and
could cause shock or fire hazard.

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.
