Hello,
I have a Pentair UltraTemp Heat Pump 110 and a Pentair Easytouch 4 control panel.
When I enable the "remote RS485" option on the heat pump to allow control from the EasyTouch, the Heater cycle's on/off every 5-8 minutes after the water drops below the set temperature. It runs for about 5 minutes and shuts back off. rinse/repeat. It sort it feels like there's no delay so when the water hits exactly the set temperature it kicks off. When it falls below the set temp even for a few seconds, the controller is calling for heat again.
This only happens when RS485 option is selected on the heat pump. When the remote setting is OFF on the heat pump, it runs for a bit and then shuts down and seems to be more of a normal function.
Has anyone experienced this before and if so have you found a solution? Looking through the EasyTouch manual, I dont see anything that sounds like it would help my issue.
I'm pretty sure the rapid cycling of the heat pump is not a good thing for a prolonged life.
Its been a few years, but hoping you are still on here.
I have had an issue with my easytouch and ultratemp h/c heat pump since i have had it (3 years).
When it is set on the RS485 option and heating the pool, it will heat it up fine...for a while. Sometimes it gets to temp, sometimes it doesnt. Eventually it will start calling for heat, run for a very short time, and shut off. Calls for heat, runs for a very short time, shuts off...keeps doing it. It's hit or miss if it will hit temp or not.
If i turn off the RS485 option and just run the heat pump manually, everything works perfectly. I have had techs and lead pentair guy over to check it out, it has the latest firmware, but still has the issue. The board on the easytouch was replaced, twice.
I'm wondering if i am having a similar issue as you. By any chance do you still happen to have the tech bulleting in a larger format where it can be read easier?
