2.4.9 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".
 For electrical connection, see
