• Battery powered (3 “AA” Energizer
®
alkaline batteries in-
cluded)
• Same program for all days of the week
• Simultaneous heat and cool program storage
• Four separate time/temperature settings per program
• Preprogrammed temperature control
• LCD continuously displays set point, and alternately dis-
plays time and room temperature
• Temperature override until next program period
• Manual program override (HOLD temperature)
• User may select either 12- or 24-hour clock display
• °F/°C convertibility
• Temperature range 45° to 90°F
• Standard five terminals for single or dual transformer
systems
• B & O terminals for single stage heat pumps or damper

PRECAUTIONS
Operator: Save these instructions for future use!
This thermostat is intended for use with a low voltage system; do
not use this thermostat with a 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.
To prevent electrical shock and/or equipment dam-
age, 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.
