I am having an issue with my Pentair Mastertemp 400 heater. When I turn on the spa or pool from my phone using Pentair ScreenLogic, or I turn it on manually from the Pentair Easytouch Control System, the heater takes a long time cycling through its startup process and then does not fire up the gas. It is reverting to 70 degrees for the pool and 95 degrees for the spa. I have had no issues with this until recently.
Before, the heater would start up very quickly and was always set at the default of 104 degrees for both pool and spa. Now, every time I turn it on, it reverts back to 70 degrees for the pool and 95 degrees for the spa. Once I turn the set temperature up to 104, the heater starts up right away.
It is frustrating because if we have the spa on, once it reaches the set temperature, it will turn off and then will not maintain the desired temperature unless I manually go over to the heater and turn the temperature up again. PLEASE HELP!
