Kids have conned me into heating up the pool to get one swim in before we have to close. So of course I had to do to. Probably the last day.

Heater works fine and controls working fine from the phone, but the heater won't go past 90 degrees (I know, that's hot, but you don't live with my wife and kids). In fact, the Intellicenter says 87F, the heater itself says 89 and the set temp is 90.

But on the Intellicenter, I turned it up to 95 and the heater won't turn on once it's at 90 on the heater lcd.

I didn't touch anything since it has been installed, was told to control everything from the Intellicenter. Heater turns off from the panel and iPhone app, so it's being controlled from the panel. Is there something else I should be looking at?

The max temp set on the heater is 95, so I'd think it could go up to 95, no?

Anything I can tweak? I just want to ensure it works.

Looks like the heater is hooked up via fireman's switch instead of rs485 in which case temp will not exceed the set temp in the mastertemp no matter what you have the ontellicenter set to. The mastertemp shows while there is a max temp programmed of 95 (ie temp cannot be set to higher than 95) it is currently set to 90
You'll need to go into the mastertemp settings (on the heater itself) to raise the set temp. Given it appears it is on the fireman's switch, it should be set to 104 max 104 set which will allow the intellicenter to cut the fireman's switch when it reaches your desired temp
