NOTES:
1. Mechanical timer is not provided with the heat pump.
2. Example only, other timers will be similarly wired.
3. Ensure that the electrical power lines are not crossed when making connections.

manual for additional setup instructions.
In serial remote operation, the heat pump is made to
start and stop via a serial RS-485 communications link
with a Pentair automation controller. This means the
remote automation controls override the heat pump’s
local set point.
However, the high and low temperature faults are still
active; the UltraTemp

Heat Pump will not heat above
104° F. or cool below 45° F.
To use the Serial Remote mode, the Intell Address screen
from the Operator Setup Menu Tree must be assigned
to the proper address. One (1) is the most commonly
used address.
The Address on the IntelliTouch Address screen must
match the address being used on the heat pump. The
heat pump address can be changed from the Operator
Setup Menu as described below:
1. Press the UP and DOWN arrows simultaneously.
The Language Selection screen should be
displayed.
2. Then press the MENU SELECT button repeatedly
until the Intell Address screen is displayed. Once
displayed, press the UP or DOWN arrows to select
the address being used in the automation control-
ler. The last address shown on the display will be-
come active.

To enable the AutoSet feature:
1. Press the MENU SELECT button repeatedly until
the AutoSet screen is displayed.
2. Press the UP or DOWN arrows to toggle between
the ON and OFF options.
AutoSet
Enable this feature any time the filter pump is off. The
AutoSet feature periodically energizes a contactor which
can be connected to the pump to move water though
the heat pump. This allows the heat pump to sense the
water temperature.
If the temperature is not at the desired level, the heat
pump starts, along with the filter pump, until the water
reaches the desired temperature. The filter pump and
the heat pump will stop when the water reaches the
desired temperature.
AutoSet allows you to set intervals (1-4 hours) to control
when the heat pump senses the water temperature. Use
AutoSet to maintain the desired pool water temperature.
To use this feature:
Be sure the water circulation pump is wired in parallel
with a mechanical time clock, using the auxiliary relay
supplied in the high voltage power panel of the heat pump.
Set the interval (1-4 hours) from the control panel to
control when the heat pump send a signal to check the
water temperature.
For example, if you program the heat pump control
board with a pump start time interval of 4 hours, have
the AutoSet feature enabled, and have a desired water
temperature of 80° F (27° C), this is the sequence of
events that will happen:
1. The heat pump displays a countdown window after
the filter pump shuts off.
2. After four (4) hours, heat pump will switch on and
start the filter pump depending on the temperature
set point.
3. The heat pump will sense water temperature then
determine if it needs to continue to circulate water.
If the pool temperature has fallen below your set
point, the heat pump will turn on and begin heating
the pool. If the pool temperature is above the set
point, the heat pump and filter pump will shut off.
4. At the time the water circulation pump shuts off,
the heat pump will reset and begin the countdown
interval and display ‘Pump Start Delay’ again.
5. The heat pump will continue this cycle every time
the water circulation pump is shut off.
6. Once the time clock turns on in the morning, the
heat pump will stop the AutoSet feature and resume
normal operation.
