its from Danfoss, which seems to be a UK supplier of hvac stuff. its got a special function that goes with our crazy hydronic /radiant system. (old school type-- black goodyear rubber tubing, hot water boiler, operating temp 160F) there appears to be a time delay function built in to the thermostat. you can switch between 8 cycles/4 min or 3 cycles/2min. not sure what the hell that means in actual practice- cycles per hour seems obvious, although the minute part i got no idea...
cant find a damn thing on the Danfoss website, i assume this is "legacy" equipment and no longer supported.
in any case, this little SOB stopped working, gives some error message and without the manual i have no idea if its fixable, but im guessing no. so what i'm hoping is that someone can tell me what kind of thermostat this is so i know what to search for online as replacement. i would assume that "adjustable cycle rate thermostat" would be close, but no luck. i tried a bunch of search terms but only found your regular everyday thermostats, none of them seemed to have adjustable cycle rates. i think that because of the weird design of our system, with the hot freakin water, the on/off cycling is part of the design and kind of important. but have had zero luck trying to find a replacement in the US. (dont want to buy it overseas)
any help appreciated.
