Operational Information

FIVE-MINUTE COMPRESSOR TIMEGUARD

This timer prevents the compressor from starting unless it has been off for at least 5 minutes. It can be defeated for 1 cycle by simultaneously pressing the FAN mode button and the INCREASE TEMPERATURE button.

FIFTEEN-MINUTE CYCLE TIMER

This timer prevents the start of a heating or cooling cycle until at least 15 minutes after the last start of the same cycle. Its function is to assure that equipment is not cycled more than 4 times per hr. This timer is defeated for 1 cycle when the desired temperature is manually changed. It can also be defeated for 1 cycle by simultaneously pressing the FAN mode button and the INCREASE TEMPERATURE button.

FIFTEEN-MINUTE STAGING TIMER

In multistage heating or cooling, this timer prevents any higher stage from turning on until the preceding stage has been on for 15 minutes. This timer is defeated if the temperature error is greater than 5°F (usually due to a large change in desired temperature).

THREE-MINUTE MINIMUM ON TIME

In normal operation, when a stage turns on, it will not turn off for a minimum of 3 minutes.

HEAT/COOL SET POINTS (DESIRED TEMPERATURES)

A minimum difference of 2°F is enforced between heating and cooling set points. This is done by allowing one setting to "push" the other, to maintain this difference.

AUTO CHANGEOVER

When the auto changeover mode is selected, a change from heat to cool (or vice versa) will not occur until an opposite mode demand has existed for 20 minutes. If the set point is changed, the 20 minute requirement is deleted. Auto mode may be disabled.

EMERGENCY HEAT MODE

When thermostat is configured as a heat pump and emergency heat mode is selected, all Y signals are locked out and W becomes energized upon a call for heat.

HEAT ON AND COOL ON ICONS

When a heating or cooling demand exists, the HEAT ON or COOL ON icon will either remain on or flash. If flashing, the equipment is temporarily prevented from turning on by one of the timers (see above). While the icon remains on without flashing, the equipment is on.

POWER ON CHECK

When AC power is first applied, all segments of the display are turned on for a few sec. Following this, the temperature display indicates the model/configuration via the following 2 digit code:

AC—1-speed air conditioner, HP—1-speed heat pump, A2—2-speed air conditioner, H2—2-speed heat pump.

ERROR CODES

--— If the thermostat cannot properly read room temperature, the display will indicate -- (2 dashes) and all outputs (except the fan if on) will turn off. This is to prevent operation of the equipment if the thermostat has failed.

E2 — If the AC line voltage drops below a minimum (brownout) level, all outputs are turned off and the display indicates E2. This condition will remain for 15 sec after proper line voltage is restored. If the AC line voltage disappears completely, the display will immediately go blank.

E3 — If the thermostat cannot properly read outdoor temperature, and it is needed for proper operation (Heat pump system and Option 8 is not set to OF), E3 will flash alternately with room temperature.
