Welcome to our forum.
Out of thousands of spas we have out there with the display reading the actual temp I don't get service calls on the spa not reading correct unless it reads dramatically different and has a sensor problem or something.If that happens we are happy that the topside let us know....
Wanna bet that HotSpring changes in the next few years to an actual temp read out?
Why do many tubs not have dual temp displays? (show actaul water temp and the set water temp?)My tiger river only shows the set temp and it seems like a lot of tubs out there don't have the dual temp display. Why? It can't really be that exspesive of an option and it seems to be a great feature. I wish I had it.
If the Green "Ready" light is lit, then the water is at the set temp, which is shown on the display.l
For me it's the convenience of knowing all is well from inside my house. If for whatever reason I would not be in the tub for a few days it would be nice to know an alarm or a quick glance by me or another family member for peace of mind. I agree, If we are comfortable at a certain temp I don't care if its a few degrees off on a display I just want to know about a hard failure.
