Heating Priority Wiring For A Monophasic Pump - Hayward ENERGYLINE INVERTER Series Installation & Operation Manual

6.2 Heating Priority Wiring for a Single Phase Pump
Terminals 1 and 2 deliver a potential-free dry contact, no polarity, rated to 230V 16A max.
The Priority Heat Timer is an integral part of the Heat Pump software and will close the potential Free Dry Contact
across terminals 1 and 2 when the unit requires the circulation pump to run. After the Heat Pump has reached set-point
temperature, it will stop the circulation pump. It will then start the pump every 1 hour and run it for 2 minutes to check
the water temperature.
The Hayward Circulation Pump Control Module can be installed by a Pool Professional before the unit is hard-wired
and installed by a qualified electrician. Isolate ALL power feeds to the Heat Pump and then connect the Control Wires
to terminals 1 and 2 as shown in the diagram below. The polarity of the connection is not important. Alternatively a
qualified electrical contractor can connect the control circuit wires for a pump control contactor to terminals 1 and 2 in
accordance with AS/NZS 3000 Wiring Rules Latest Edition.
WARNING –
Dry contact 16A max potential free.
