Hey all,
Curious if anyone may have any ideas on how to solve an issue im having. My MaxEtherm 400 heater is hooked up to my Intellicenter via Rs485. System works perfectly. I also have an external bypass with an actuator to bypass the heater when there is no call for heat. This is currently controlled by the Intellicenter.
I switched the actuator off the Intellicenter and over to control by the Heater the other day and enabled the bypass function in the heater. When a call for heat is made, the Heater moves the actuator as it should, all is well. When the call for heat ends, the heater will never move the actuator back to the bypass position. It also shows “cooldown” and wont move off of it on the heater display.
If I cycle the power on the heater with the breaker, once turned back on it will move the valve back to its home (bypass) position until another heat call is made. I disconnected the RS485 from the Intellicenter and let the heater “run the show” itself, it behaves exactly how it should in that case. It moves off the cooldown phase and moves the actuator back to bypass exactly like it should.
It seems to me it’s something to do with controlling the heater with the RS485 and having bypass mode enabled on the heater. Also worthy of note, when the heater does not have the actuator bypass enabled, and its being controlled via RS485, it does not sit there in the cool down phase indefinitely after finishing a heating cycle like it seems to do when the bypass mode is enabled. I have tried having the cooldown delay set to both 2 mins and off in the intellicenter and that had no change.
I have an email in to Pentair on it, anyone have any ideas or seen this before?
