DESCRIPTION

These “Level-Temp” controls have been designed to

operate with a White-Rodgers low-voltage electric heat

thermostat to provide a system for controlling electric

warm air heaters and electric radiant heating devices

such as duct heaters, wall heaters, baseboards, floor and

ceiling cable heaters.

When required, two or more Level-Temp Silent Opera-

tors can be operated by one two-wire low voltage thermo-

stat.

The operator has been carefully adjusted. No attempt

should be made to adjust it after it leaves the factory.

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.

Do not use on circuits exceeding specified

voltages. Higher voltages will damage control

and could cause shock or fire hazard.

To prevent electrical shock and/or equipment

damage, disconnect electric power to system, at

main fuse or circuit breaker box, until installation

is complete.
