Vitodens 200 WB2 hot water not prepared as result of reset of control unit.

Vitodens 200 WB2 hot water is not prepared by time, nor the Party option. Only way, how can I prepare hot water to switch off option - control unit behave in a reverse way.

Thank you for assistance.

Kind regards °pa

Thank you for your feedback.

Temperature for hot water is displayed correctly in control unit (compared with thermometer on boiler itself). Problem is, that hot water is not prepared in time interval set in control unit, nor by using Party option. The only way how to prepare hot water manually is by using standby mode option (leftmost option on upper rotary switch - control unit for weather - compensated mode with standard unit) or by Reduced room temperature option. In this situation the hot water is prepared, but regardless the temperature limit set by control unit (I have set 55 degrees Centigrade), hot water has 75 degrees Centigrade.

Thank you for your assistance.

Best regards.
