I set my BDR91 for underfloor heating 6 times per 1 hour with minimum run time 5 min. BDR91 is not following command, it starts and runs less than 5 min, sometimes 2 or 3 minutes and stops. Does it has something to do with Opentherm relay for boiler? if boiler goes to st-by mode ( request temp reached set point) the BDR91 stops?
If BDR91 stops for the underfloor pump, does boiler with opentherm relay should go to st-by mode directly? if not, how to achieve it?
