SensaHeat Heat Pump Relay Controller - for Balboa SpaNet Gecko Davey etc

The SensaHeat Heat Pump Relay Controller is the perfect and easiest solution for plugging in Sensaheat heat pumps into spa control systems such as Balboa, Spanet, Gecko/Aeware* and other systems that normally have a 230V heater element built-in.

This kit allows you to control your heat pump via your standard spa touchpad. 

Compatible with all Sensaheat PI & ES heat pumps.

Note: As of October 2023 the unit has changed and has a 240V relay rather than the box as old photos show. Relay must be placed in a protected place by your electrician.

Basic Instructions:

1. Disconnect heater element in your spa controller.
2. Connect Active & Neutral to the spa controller heater terminals.
3. Plug Relay Controller into Heat pump. Plug 5-6 on PI & ES (later models). For Older ES models, bridge into DIN1 wire loop.
4. Set temperature on heat pump to 40°.
5. Control heat pump via spa's standard touchpad.

Note that some Gecko/Aeware control systems need a 'dummy' load. You can leave heater element connected in these situations, or your electrician can connect a dummy load to the element such as a light transformer, etc.
