Or maybe you stayed at a Holiday Inn Express? I'm trying to crowdsource some knowledge as I attempt to replace my hot tub pump and motor.
So I've got a Softub which if you're not familiar is a circular foam tub with the jets and everything and then a separate egg shaped thing that connects the water input/output/air for bubbles and a couple wires for the underwater lights. The egg has holds the pump and motor and the electrical control box. There's no heating element, instead the water is circulated through coils around the pump and sucks the heat from there. It's very easy to move and set up as it's lightweight and uses 110V hookup.
So, old pump leaked and blew. I entered the model number from the old one and found what I thought was a good replacement. As I was hooking it up however there was an extra hot wire coming from the control box to the pump and only a hookup for one on the pump motor. Turns out the old motor was a 2 speed motor and the new one is a single speed. The black wire for high speed and red for low. Called the guy I bought it from and he said others had just used the high speed as the low was just for circulation and not enough to actually heat. So he said wrap up the red wire with electric tape hook the high speed to the motor. He was wrong. I did what he said and everything seemed to be working. Jets came on and off, all the controls worked. Great. The jets will go off after an hour if you leave them on but according to the guy (who does not specialize in this type of tub) it will also heat with high speed. After an hour no jets were on to heat. They'd turn on if you pressed the button but the red "heat" light was on indicating that it should be heating. So clearly it heats on the low speed.
So, send it back and get yourself a 2 speed motor mturn. I can't find one that I can put those heating coils on. All the 2 speed spa pumps have some funky hump on them.
So I have two ideas. The first is to switch and hookup the low wire. The pump doesn't have a low speed but assuming the voltage from both wires is the same it should run on high whenever the control panel tells it to (i.e. the heat cycle). But I'd lose control of the jets. They would likely come on when using it anyway in cold weather because just the heat from the motor can't keep it at high temps with the lid off. But at least I'd have a "hot" tub.
Now, my question is what if I hook both wires up to the motor. The relay won't send power from both hot wires at the same time which would almost certainly cause a short. And there are two nodes to hook up to the same hot terminal. My coworker thinks that them just sharing that therminal might cause a short as the circuit tries to complete by running back up the other hot wire that's not pushing at the time.
I'm still trying to find a 2 speed motor that will work but if not want to make something work. Thanks in advance. I'll buy you a beer or give you free tax advice in return for you reply.
