DeScripTion

These Level-Temp Silent Operator relays are designed for use
on electric heating equipment in conjunction with White-Rodgers
low voltage thermostats. They are especially suitable for use on
baseboards, wall insert heaters, etc. Some models also have
an inductive rating to permit them to be used on motor loads
where a time delay is desired.
Different models of these Silent Operator relays are available
for voltage inputs of 120, 208, 240, 277, 347 or 600 volts. Since
these relays are equipped with a self-contained transformer, the
supply voltage used must agree with the voltage rating of the relay.
When required, two or more of these Silent Operator relays can

be operated by one low voltage heating thermostat. These Silent
Operator relays have been carefully adjusted at the factory. No
attempt should be made to adjust them in the field.

If in doubt about whether your wiring is millivolt, line, or low
voltage, have it inspected by a qualified heating and air condi-
tioning 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 components could cause
the control to malfunction.

WARNING

!

Do not use on circuits exceeding specified voltages.
Higher voltages will damage control and could cause
shock or fire hazard.

CAUTION

!

To prevent electrical shock and/or equipment damage,
disconnect electric power to system, at main fuse or
circuit breaker box, until installation is complete.
