6.14 ELECTRICAL UTILITY LOCK
6.14.1 Electrical Utility Lock
Default setting is Disabled.
Electrical Utility Lock or EUL is used in some countries, where the Industry has a high
demand on electrical power one or multiple times a day. The electricity distribution
companies send a signal to Households that stops all high power electrical consumption
systems. The heat pump belongs to this group, meaning it needs to stop during this time. If
there is an additional heating source that is not in this EUL group, it can be automatically
switched on during this period (see chapter 6.13.3).
A potential free contact is used and connected to the terminals ES and COM.
There are two possibilities of signal used for this function
– Normally open (NO) and normally
closed (NC).
If this function is enabled and a signal comes the compressor will stop for heating mode,
DHW mode and Cooling mode.
For systems with active Electrical Utility Lock a buffer is recommended, so that the heat
stored in the buffer can be used for heating the house.
