The controller is not acting as a thermostat as there are no heating circuits associated. Manually cycling through the 3 operation modes back to STANDBY will resolve the boiler problem until it drops to ~18 deg C and then it starts over again. Disconnecting the QAA73 from the boiler resolves the problem and the boiler works fine (CH & DHW). What is it about the QAA73 that is causing this aberrant boiler behavior? THANKS!
