Hi! I just got this system installed. Seems to be working well. However, I hear a continuous noise that seems to be the water circuit pump, I can see it running in the vicare app even when the burner is off because there is no heat demand from the thermostat. This is a little bit disturbing due to the noise and I wonder if such a continuous run of the pump would reduce its life span. I tried changing param 1240.0 from 1 to 7 to see if the pump would stop when there is no heat demand but I got error 574 which does not make any sense to me. Here is the description of the parameter from the manual: 2 Primary pump operating mode (Parameter 1240.0) Setting Explanations - 1 "Automatic" => Switched on regardless of current temperature level - 7 => Switched off in reduced mode (in conjunction with constant operation with time program) or if there is no demand via the room thermostat. Wondering if anyone can help me with this. Thanks, Julio
