No DHW preheating after a power failure
Posted: Wed Feb 06, 2019 10:31 am
I have Vitodens 100 (boiler 230V power supply) and iSense AD 289 (thermostat powered from OTG) and between them is OTG (battery power supply). Everything works well but after the 230V voltage recovery, after a voltage failure when the boiler does not work, the boiler does not heat up the domestic hot water to the set temperature, the rest is working correctly. After disconnecting and reconnecting the thermostat, everything returns to normal. Can this problem be solved by issuing a command in the OpenTherm Monitor application?
