This wall-mounted, low voltage thermostat maintains

room temperature by controlling the operation of multi-

stage systems. Use this thermostat for applications

requiring up to three stages of heat and up to two stages

of cool. Indicator lights show the system status. The user

may program up to four time/temperature settings per 24

hour period. The thermostat stores programs for seven

independent days. The thermostat will store both heating

and cooling programs simultaneously. A 9 volt Energizer

battery will maintain the stored program for approximately

one week, if incoming power should fail. If power failure

is extensive and the program is lost, after power restora-

tion, the thermostat will automatically maintain a factory

preprogrammed heating temperature of 64°F or a cooling

temperature of 82°F.

Multi-stage Electronic Digital Thermostat

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.

DESCRIPTION

W H I T E - R O D G E R S

DIGITAL COMFORT SET

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.

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 volt-

age. Higher voltage will damage control and

could cause shock or fire hazard.

Do not short out terminals on gas valve or pri-

mary control to test. Short or incorrect wiring will

burn out thermostat and could cause personal

injury and/or property damage.
