Lock individual sequences
In operating mode "Heating", the sequence assigned to function block
"Refrigeration demand" is locked.
In operating mode "Cooling", the sequence assigned to function block "Heat
demand" is locked.
Heat / refrigeration demand
In operating mode "Heating", "Refrigeration demand relay" is locked, refrigeration
demand set continuously to 0%, and no refrigeration demand signal is sent to the
bus.
In operating mode "Cooling", the heat demand relay is locked, heat demand set
continuously to 0 %, and no heat demand signal is sent to the bus.
Locking time
To prevent the refrigeration machine from switching on immediately following
switch-off of heat generation, a locking time can be set.
Control is locked during the "Locking time"; as a result, no heat or refrigeration
demand is generated or signaled.
Excessive inlet temperature at the refrigeration machine can damage the
refrigeration machine.
