 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.
