FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE
INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL
INJURY AND/OR PROPERTY DAMAGE.
These Level-Temp Silent Operator relays are designed
for use on electric heating equipment in conjunction with
White-Rodgers low voltage thermostats. They are espe-
cially 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.
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.

INSTALLATION INSTRUCTIONS
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.
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
voltages. Higher voltages will damage control
and could cause shock or fire hazard.
Room Thermostat:
Set adjustable heat anticipator at 0.2 Amps. For fixed
anticipation thermostats, use 0.15 to 0.25 Amp. heater.
