Questions and answers
Переключая на отопление не происжодит розжиг 3 сек моргает красный потом горит две зеленые. На горячую воду все работает.
When the Nova Florida VELA COMPACT flashes red for 3 seconds and then shows two green lights when switching to heating, it indicates a normal transition during startup. The red flashing likely signals initial system checks or ignition, and the two green lights show that the boiler is operating in heating mode with a flame present.
