Universal Heat Pump Controllers - Heat Pump Pool Pump Control aka J-Box / MJ Box

The universal IntelliHeat Heat Pump Controller is a controller to use with most brands of Pool & Spa Heat Pumps. 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 only (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.
