Timers And Delays
1. Water Sensing Timer
One minute timer to allow water from the pool to
reach the UltraTemp
®
Heat Pump before acquiring
temperature. This timer initiates when water first
begins to run from stopped or low water flow
conditions or when the heat pump is turned ON.
Countdown time is in Minutes and Seconds.
2. Restart Delay Timer
Five minute timer is a protection feature for the heat
pump’s compressor. This extends the life of the
compressor’s by not allowing it to cycle on and off,
(i.e. adjusting set point up and down around actual
temperature). Countdown time is in minutes and
seconds.
3. Defrost Delay Timer
Fifteen minute timer where the Heat pump is in
Defrost operation. Countdown time is in minutes
and seconds. Refer to page 18 for more details on
the defrost cycle.
4. Pump Start Delay
One to Four Hour timer used in conjunction with
the AutoSet feature. Counts down the time until the
control board will energize the internal contactor in
the heat pump to turn on. Countdown time is in hours
and minutes. See AutoSet section for more details.
5. Heat Pump Runtime 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 operator can
change set points, functions, etc. The heat pump’s
Green LED Indicator will turn OFF and the heat pump
will stay OFF when time expires.
