Primary Boiler Circulator Question
Posted: Sat. Feb. 25, 2012 2:38 pm
I have my radiant floor set up with a KA-2. I have a Primary loop and 3 zones off the Primary controlled by sepeate circulators. I have Tekmar 3 way valve to be able to supply the zones with apprx. 130F water temp.
Recently I noticed that while a zone is calling for heat and that circulator is running the supply temp if good. Then while being down by the boiler last eek I notice that while the zone circulator was running the Primary circulator came on and the water temp climbed about 15 degrees. The it fell back as soon as the Primary shut off.
The house is comfy and this is season #2.
I checked how the Primary is wired and it is as instructed.
So what's up?
Also,I probably should know, what is the criteriea for the Primary to turn on?
Thanks!!
