Rheem IQ Dpi-2 Link - DIGITAL PUMP INTERFACE

DESCRIPTION
The Rheem IQ® Link DPi2 controller is suitable for connection to a single filter pump
system including automated chlorinator in combination with a Rheem Thermal heat pump.

OPERATION
The DPi2 controller is designed to switch a 240V filter pump, rated to 9.98 Amps, 2395 watts from the Link DPi2 controller ‘PUMP CONNECTION’ output. The DPi2 controller is also designed to be connected to a chlorinator via the ‘CHLORINATOR CONNECTION’ lead and the ‘HEATER INTERLOCK’ output lead to a Rheem Thermal heat pump. The DPi2 has an LCD screen, which displays whether the filter pump is ‘on’ and whether the chlorinator or heat pump is demanding the filter pump to be operating.

DEMAND HEAT
Your Rheem Thermal heat pump includes Rheem IQ® which provides a range of advanced
control functions to aid operation and service. This includes a ‘CYCLE TO TEST
TEMPERATURE’ function that will assist in maintaining the temperature of the pool or spa by communicating to the DPi2. As most pools and spas are chlorinated and filtered for between 4 to 8 hours a day, extra run times are often needed to maintain the pool or spa water at the desired temperature. The DPi2 allows for Rheem IQ to monitor the pool temperature by run-cycling the filter pump outside of the hours programmed by the chlorinator.

PROGRAMMING DEMAND HEAT
To program and switch on the demand heat function in the Rheem Thermal heat pump
controller, refer to the back page of these instructions.
