The universal IntelliHeat Heat Pump Controller is a controller to use with most brands of Pool & Spa Heat Pumps. Made by Dontek. Can be used in place of a Madimack MJ box, EvoHeat J-Box, Zodiac Intelliheat and suits almost all brands of pool and spa heat pumps. This is designed to operate a pool Pump when either a Chlorinator or a Heat Pump needs the pump to run.

It allows your pool pump to be overridden by a heat pump's internal "Heat Demand" system. <-- many of the brand names of heat pumps have the ability to switch a pump on.

This works with brands such as SensaHeat, Madimack, Hayward, Rheem, Raypak, Zodiac and many others. Suitable for low-voltage switching (eg: flow switch circuit).

Choose between these options:

Standard - where your heater is installed on the same plumbing line as the pool's filtration system.
Standalone - where your heater is on its own dedicated pipework which is separate from the pool's filtration plumbing.

Note: Made by Dontek. May be branded Dontek, Zodiac, Sensaheat, Henden, Theralux depending on availability. They're all the same units with different labels.
