DUAL LEVEL-TEMP
SILENT OPERATOR RELAY
(Normally Open Contacts)
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, 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.
The Silent Operator relay has been carefully adjusted at the factory, and no attempt should be made to adjust them in the field.
PRECAUTIONS
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.
! 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.
!WARNING
Do not use on circuits exceeding specified voltage.
Higher voltage will damage control and could cause shock or fire hazard.

INSTALLATION
The Dual-Level Temp relay may be mounted in any position without affecting it's performance.
It can be connected using the 1/2" male conduit hub and can be mounted to any standard junction box or wiring compartment.
It can also be mounted using the two holes in the back of the case. Location of the mounting holes may be simplified by holding the control against the mounting surface and marking the proper position for drilling the holes.

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.
NOTE
Use thermostat with a .4A fixed heater, or set adjustable heater in thermostat at .4A.

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.
