Overview
For your information
Technical terms are explained in the glossary (Page 20). They are identified in the text by an *.
The setpoint adjuster HCU 23 is a component of the storey controller system HCE 40 from Honeywell. It controls the setpoint temperature* of a room. To do so, it measures the temperature in the room and sends the setpoint temperature information to the storey controller HCE 40. The setpoint adjuster is equipped with a series of convenient functions:
•You can set your own times and choose from two different setpoint temperatures to set up your own heating programme for each day of the week
•The unit can be switched between automatic mode* and manual mode* at any time
•Integrated room temperature sensor
•Automatic switching between summer/winter time

Start-up
You can assign each temperature zone* of the storey controller to the setpoint adjuster. Connection and assignment occur via the cabling. The HCU 23 functions as a setpoint adjuster* and time program transmitter*.
Assigning setpoint adjuster as setpoint transmitter
►Lay out the zoning plan* of the storey controller.
►Attach the connector of the setpoint adjuster to the connectors of the storey controller as shown in the diagram on the following page.
If you are using only one four-lead cable, you must bridge terminal 19 to a ground connection (e.g. terminal 17). You can renounce the ground connection of the storey controller (terminal 5).
