Connecting a heating system (Aux 4)
The Aq is compatible with all types of pool heaters such as heat pumps, electric heaters or even heat exchangers.
Connecting to a Hayward heating system fitted with a remote On/Off control
Connect a 2 x 0.75 mm² electric cable (not supplied) across terminals (13)-(14) of auxiliary contact Aux 4, then connect it across
the DI01 and GND terminals on electronic circuit board PC1001 of the Hayward heat pump or any other compatible equipment
(see the installation instructions). Set the set point of the heat pump or heating system to maximum. The Aq will use its
own water temperature probe to control the heating set point.
