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 voltage.
Higher voltage will damage 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 damage
thermostat and could cause personal injury and/or
property damage.

flexibility to design heating and cooling programs that fit your
needs.
Features:
• Separate program for each day of the week
• Simultaneous heat and cool program storage
• Preprogrammed temperature control
• Four separate time/temperature settings per 24 hour period
• LCD continuously displays set point, and alternately dis-
plays time and room temperature
• Temperature override until next program period
• Manual program override (HOLD temperature)
•

• Eight terminals for single or two-transformer systems
• O/B terminal for heat pump systems
• Armchair Programming Capability
This thermostat is intended for use with a 24 volt system; do not
use this thermostat with a millivolt or line voltage system. If in
doubt about whether your wiring is millivolt, line, or low voltage,
have it inspected by a qualified heating and air conditioning
contractor or electrician.
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.
