WHITE-RODGERS

TYPE 829A-845

RELAY

For Use With Low Voltage Thermostats

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

Type 829A-845 Relay has double-pole, single-throw switching action.

This relay is especially suitable for use on hot water heating installations having forced circulation. It permits the use of a sensitive low voltage room thermostat to control the operation of both burner and circulator.

It is equally well suited for use on zoned hot water installations where a circulator and low voltage thermostat are used for each zone.

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 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.

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 voltages. Higher voltages will damage control and could cause shock or fire hazard.

PRINCIPLE OF OPERATION

The 829A-845 relay is provided with a self-contained transformer with a low voltage secondary output for energizing the relay coil.

Line voltage lines should be connected to the terminals marked “1 & 2” for power to reach the transformer. Closing the thermostat circuit energizes the relay coil which in turn closes the circuits between terminals 3 and 4 and also between 5 and 6.

Opening the thermostat circuit de-energizes the relay coil, breaking the circuits between terminals 3 and 4 and also between 5 and 6.
