FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY

BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE

PERSONAL INJURY AND/OR PROPERTY DAMAGE.

DESCRIPTION

This wall-mounted, low voltage thermostat maintains

room temperature by controlling the operation of heating

and cooling systems. The user may program up to four

time/temperature settings per 24 hour period. The ther-

mostat stores independent heating and cooling programs

for 5-day (weekday) and 2-day (weekend) periods. The

thermostat will store both heating and cooling programs

simultaneously. Three “AA” Energizer

batteries will main-

tain the stored program for approximately one year, if

incoming power should fail. If power failure is extensive

and the program is lost, after power restoration, the

thermostat will automatically maintain a factory

preprogrammed heating temperature of 64°F or a cooling

temperature of 82°F.

Troubleshooting

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.

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 the control and

could cause shock or fire hazard.

Do not short out terminals on gas valve or primary

control to test. Short or incorrect wiring will burn

out thermostat and could cause personal injury

and/or property damage.
