I would like to be able to control my hot tub, Dimension One, temperature using my home automation system. The one thing I haven't worked out yet is how to defeat the heat control to
to cause the heater to stay on regardless of its temp setting.
Ideally what I'd like to have happen is to have the heat control on the tub set to a cool setting,
just enough to keep things from freezing, that I can override with a relay to force
the heater to stay at maximum heat. I have a temp sensor attached to the tub
that my automation system will monitor the water temp and when it reaches our desired temp
will shut off the relay, hopefully putting the tubs heat control back on and shut off
I would think the easiest thing to do would be to interrupt the connection to the temp sensor
to force the heater to stay on?
Any ideas greatly appreciated!
