Some common alarms are:
Internal immersion heater: This is most often caused by poor flow or air in the coil inside the hot water tank or heating circuit, or
before the circulation pump. Bleed thoroughly and reset overheat protection T1 on the electrical cabinet when the temperature has
decreased.
High pressure: This is most often caused by poor flow or air in the coil inside the hot water tank or heating circuit, or before the circula-
tion pump. Bleed and reset alarm.
Low pressure: Make sure the evaporator is free from leaves, pollen, seeds, snow, ice or other debris. Make sure the fan is rotating freely.

hot water consumption.

"Normal" (default) is the best compromise between energy efficiency and hot water availability.
▪
"Comfort" is the choice for customers with large demands of hot water availability.

"Low" is a setting to use typically during time away from home. The hot water function can never be turned off completely, to
