4.0 OPERATING MODE

If the thermostat activates heating, cooling, or constant fan operation, the numeric display will read ON. Otherwise,

the display will read FAN OFF and will indicate the time remaining until the fan is activated again. Once activated, the

display will read FAN ON and the time remaining for FAN ON time.

The model FR-V has additional settings for outside air damper cycling. When the fan turns on, the damper will open and

the display will read VENT ON and indicate the time remaining until the damper closes. Once the VENT ON time has ex-

pired, the damper will close and the display will read VENT OFF and indicate the time remaining until the damper opens

again. This cycle continues for as long as the fan is running. The vent will be closed any time the fan is not running and

VENT ON and VENT OFF times will be reset to programmed values.

4.1 POWERING OFF

Warning: It is not recommended to turn off the AirCycler® if the unit is used as a ventilation controller. The AirCycler®

can be turned off during extended vacation periods or when the windows are open. It is very important to turn the Air-

Cycler® back on after those periods.

1. In normal Operating Mode: Press and hold the Mode Key for six seconds to turn off the AirCycler®. All thermostat

functions will continue to operate normally.

2. To turn the AirCycler® back on, press the Mode Key.

4.2 TESTING

The Test Mode will display fan activity in seconds rather than minutes. To activate Test Mode, follow these steps:

1. Press the Mode Key once and then press it again and hold for six seconds. The display will indicate TEST.

2. Exit Test Mode and return to Operating Mode by turning the AirCycler® off.

3. Hold the Mode Key for six seconds, and then press Mode again to turn on the AirCycler®.

NOTE: As a safeguard, the AirCycler® will automatically exit Test mode after ten minutes.
