Just got my new Buderus G115 installed last week, with logamaitc, outdoor reset, and room sensor. We have a single zone and DHW.
I am curious whether the single zone circulator pump is supposed to be running constantly, even when there is no call for heat. Yesterday it was about 65-70 outside, room sensor was set to about 68, actual room temp was about 72, and the water seemed to be circulating constantly even though there was no call for heat in the house. I eventually figured out to drop the outdoor temp cutoff to 62, so summer mode kicked in, but it seemed odd that the ciruclator would be constantly running when the room temp was higher than the set temp. When the DHW production kicks on and the single zone circulator is going, doesn't that circulate hot water around my house?
Also, on the logamtic the room temp was showing 79, even though it was actually about 72 in the room accoridng to a regular thermometer. Any idea why it would have such a high difference?
