2. Restart Delay Timer
Five (5) minute timer is a protection feature for the
heat pump's compressor. This extends the life of the
compressor by not allowing it to cycle on and off
rapidly, (i.e. adjusting set point up and down around
actual temperature). Countdown time is in minutes
and seconds.

the AutoSet feature. Counts down the time until the
control board will energize the internal contactor in the
heat pump. Countdown time is in hours and minutes.

5. Heat Pump Runtime Timer
This feature is an adjustable timer to allow the heat
pump to run (green light ON) for a predetermined
amount of time and then turn OFF (green light OFF).
During the selected time frame the green light is ON
and the heat pump will function in the normal mode
of operation and/or the operator can change set
points, functions, etc. The heat pump's green light
will turn OFF and the heat pump will stay OFF when
time expires.
