Configuration and electrical connection
Connecting setpoint adjusters HCU 23 and HCW 23
Setpoint adjusters of type HCU 23 and HCW 23 are hard-wired.
Use cables in accordance with the table on Page 24.
►
Attach the connectors of the setpoint adjusters to the connector of the
►
storey controller as shown in the following diagram.
One setpoint adjuster (max.) can be used with the central
operating device HCM 100.
If you are using only one four-lead cable for the setpoint
adjuster HCU 23, you must place a jumper between terminal
19 and a ground connection (e.g. terminal 17). You can
connect it to the ground connection of the storey controller
(terminal 5).
