DESCRIPTION
The Rheem IQ®Link DPi1 controller is suitable for connection where a separate pump
is installed on a heating circuit in combination with a Rheem Thermal heat pump.
OPERATION
The DPi1 controller is designed to switch a 240V pump, rated to 9.98 Amps, 2395 watts
controlled from the ‘HEATER INTERLOCK’ output of a Rheem Thermal heat pump.
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 DPi1. The DPi1 will start the circulator pump when heating is
called for by the Rheem IQ®controller, which monitors the pool or spa temperature.
