1 Defrost sensor (evaporator sensor)
2 Supply air sensor
4 Return air sensor/room air sensor
y = Case part 1..8 Case part 1..8
All leads running to and from the UA 300 D − especially those of the CAN bus − must be shielded! No
shielding is required on sensor leads when installed exclusively inside the refrigerated display case
and when external interference (for example from parallel power wires) is not to be expected.
