BLOCKING
In "BLOCKING" cases, the system changes to "emergency mode economy". The heat
pump is switched off. The system is controlled at reduced temperatures (heating and
warm water) and the additional heat generators (electro auxiliary, furnace) take over the
heating (if installed). An automatic restart is only possible when blocking function is no
longer active.
