the UP or DOWN arrows to scroll through the heat, cool and auto options. The last option shown on

4. Heat Pump Timer – This feature is an adjustable timer to allow the heat pump to run (Green LED ON)
and then turn OFF (Green LED OFF) for a predetermined amount of time. During the selected time frame
the Green LED Indicator is ON and the heat pump will function in the normal mode of operation and/or the

the heat pump will stay OFF when time expires. Countdown time is in hours and minutes.
