INSTALLATION INSTRUCTIONS

Operator: Save these instructions for future use!

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.

DESCRIPTION

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 heating-cooling thermostat to control heating and cooling loads alternately as in motels,

apartments, ofce 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.

The Silent Operator relay has been carefully adjusted at the fac-

tory, and no attempt should be made to adjust them in the eld.

PRECAUTIONS

If in doubt about whether your wiring is millivolt, line, or low voltage, have it inspected by a qualied heating and air conditioning contractor, electrician, or someone familiar with basic electricity and wiring.

Do not exceed the specication 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.

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 specied voltage.

Higher voltage will damage control and could cause

shock or re hazard.

WIRING AND OPERATION

All wiring should be done in accordance with local and national electrical codes and ordinances.

If a wiring diagram is supplied with the heating equipment, follow those instructions. If none is available, two diagrams are presented which show different wiring methods for the Silent Operator relay.

OPERATION

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.

WIRING AND OPERATION (cont.)

All wiring should be done in accordance with local and national electrical codes and ordinances.

OPERATION Heating

As the “Heat” contacts of the thermostat close, bimetal heater #1 is energized. Approximately 45 seconds later, the warping action of bimetal heater #1 closes line voltage switch #1 to energize the heating load. When the "Heat" contacts open, heater #1 cools for approximately 45 seconds before switch #1 opens to de-energize the heating load.

Cooling

As the "Cool" contacts of the thermostat close, bimetal heater #2 is energized. Approximately 45 seconds later, the warping action of bimetal heater #2 closes line voltage switch #2 to energize the cooling load. When the "Cool" contacts open, heater #2 cools for approximately 45 seconds before switch #2 opens to de-energize the cooling load.
