Multimaster function
The multimaster function can control up to six cooling connected cooling units (bus functions). It regulates the
cooling mode as follows:
The first cooling unit that reaches the "TSet + 2K" switching threshold activates cooling mode in the bus
function.
The cooling mode is ended by the last unit that undercuts the switching threshold "TSet 2K".
Energy-saving mode is ended by the cooling command of one of the cooling units in bus function.
Energy-saving mode is re-activated 30 minutes (condition as supplied) after the last cooling command of one of
the cooling units in the bus function.
All cooling units in the bus function can activate or end cooling mode or energy-saving mode. There is no
"master and slave function".
