I recently installed a Froling FHG 40/50 with a US S3200 V2 controller.
I put a relay on the 230 volt pump feed so that I could run 115 volt circulators. My understanding is in the USA Tarm supplies this relay, in Canada my dealer said buy a 230 volt pump. I'm running 3 pumps that I already had so I installed a general purpose 230 V coil relay. The relay seems to work fine, it clicks the pumps on when the boiler reaches 65 degree C but it does not click off when the boiler goes to "OFF" mode or even below 65 degrees. Is this its normal operation? I do not have the storage tank sensors installed in the tank. I only have "Customer Level" access to the controller. If this is a setting in "Service Level" access, I would appreciate if anyone could give me the access code. I hope the controller doesn't have some VFD or something for the pump and that I have fried the controller.
I have an Eko 40 with a RK2001AT2 controller that I used before installing the Froling that gave me the option to turn off the circulator based on flue temperature and time. I am thinking the Froling could do the same with the additional information of oxygen percent.

I appreciate any information on what the controller can or can not do.
