temp.
MC Ther. toggle Master control signal used for switching case load
ON/OFF depending on the load condition
MC Load request Master control signal used to control the load balance
between multiple case controllers on the same suc-
tion line
MC Max. Te offset Requested offset to actual evporating temperature in
order to keep the air temperature at the actual set-
point
MC Liquid control Master control signal allowing switch to adaptive liq-
uid control
MC Night setback Master control signal for changing between day and
night time operation
MC Case shutdown Master control signal used to shut down a case for a
time period. During shutdown there will be no alarm
