INFORMATION
When the DHW tank booster mode is active, the risk of
space heating/cooling and capacity shortage comfort
problems is significant. In case of frequent domestic hot
water operation, frequent and long space heating/cooling
interruptionswillhappen.
Scheduledmode
In scheduled mode ( ), the DHW tank produces hot water
corresponding to a schedule. The best time to allow the tank to
producehotwaterisatnight,because:
▪ Thespaceheatingdemandislower
▪ Electricitytariffsarelower
