This Dual Level-Temp Silent Operator Relay is designed for
controlling two separate loads with a single low voltage
thermostat. It is especially suitable for use with electric heating
equipment.
The Dual Level-Temp relay may be used to operate two
separate heating loads by means of a single low voltage
thermostat. It is equally well suited for use with a heatingcooling thermostat to control heating and cooling loads alternately as in motels, apartments, office buildings, etc.
This model Dual Level-Temp relay has a voltage input of 240
volts. Since this relay is equipped with a self-contained transformer, the supply voltage used must agree with the voltage
rating of the relay. This model has both an inductive and noninductive rating.

PRECAUTIONSPRECAUTIONS
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 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.

As the thermostat closes its contacts, bimetal heaters #1 and
#2 are energized. Approximately 45 seconds later, the warping action of these heaters closes line voltage switches #1 and
#2 to energize heating loads #1 and #2.
When the thermostat opens its contacts, bimetal heaters #1
and #2 cool for approximately 45 seconds before line voltage
switches #1 and #2 open to de-energize the heating loads.
