Low voltage switch for 120 vac spa tub heater

Good morning,

Have a Jason spa tub with a 104 flow contolled heater. At times I would like to turn off the heater and still have the jets running. Right now heater is on whenever spa is pumping.

Does anyone have a circuit that would allow a low voltage switch to turn on\off the 120 vac heater? Thought about maybe a 12 volt or 24 volt doorbell transformer with a simple toggle switch.

Thanks for any ideas.

DJ

You would have to post a wiring diagram for help with that. Anything added needs to be done safely to maintain the integrity of the safety systems. You also don't want to create a shock hazard.

Doorbell transformers are usually neither 12 or 24 volt. What you would need is often called and an auxiliary or control transformer (and probably better quality). Actually to reduce shock you may want to use an air switch. That in turn would control the contactor ( relay) that controls the heater. Examples: Amazon.com: spa air switch. But we will need the wiring diagram PJ requested before going further.
