DencoHappel ZGF.1E series Operation Manual page 113

Flex-Geko Fan Coil Unit
PR-2011-0115-GB • Subject to modifications • R4-12/2015
Unit printed circuit boards of the MATRIX 3000 control system and MATRIX
OP3X/44/5X control panels are equipped with terminating resistors.
Terminating resistors are placed at line start and end (Fig. 7-9):
• Set the DIP switch on both users (e.g. control panels, unit PCBs or modules)
in "ON" position.
The line beginning and line end correspond to the start and end of the bus cable.
The terminating resistors must also be switched on for stand-alone units.
