CIAT V3000 KNX - Connecting the Frame Contact; Input Configuration (P51;P52); Window Contact Wiring

● Universal inputs
The V3000 controller is equipped with 2 congurable potential free inputs. These 2 inputs D1-C and D2-C are delivered from the
factory with a bridge. If you want to connect contacts to the inputs (frame contact for example), the bridges must be removed.
- Universal input D1
 This input can be congured using parameters P49 and P51
- P49: Action direction of contact, NO or NC
- P51: Enables you to slave controller operation to contact opening or closure, with the possible set-up below:
- 0: Inactive
- 1: Window contact comfort → Frost protection (local override impossible)
- 2: Presence contact comfort → Eco (local override impossible)
- 3: Presence contact comfort → Standby (local override impossible)
- 4: Condensate pump alarm: fan coil unit switched off and cold valve closed
- 5: Fan unit motor alarm: Complete fan coil unit shutdown
- 6: General alarm: Complete fan coil unit shutdown
- 7: Air quality information: enables you to send via the bus a "low air quality" signal to the room. An On-Off controller output
may be synchronised with this information.
- 8: Clock for switching Comfort → Eco (local override authorised)
- 9: Clock for switching Comfort → Standby (local override authorised)
- Universal input D2
 This input can be congured using parameters P50 and P52
- P50: Action direction of contact, NO or NC
- P52: Enables you to slave controller operation to contact opening or closure, with the possible set-up below
- 0: Inactive
- 1: Window contact comfort → Frost protection (local override impossible)
- 2: Presence contact comfort → Eco (local override impossible)
- 3: Presence contact comfort → Standby (local override impossible)
- 4: Condensate pump alarm: fan coil unit switched off and cold valve closed
- 5: Fan unit motor alarm: Complete fan coil unit shutdown
- 6: General alarm: Complete fan coil unit shutdown
- 7: Clock for switching Comfort → Eco (local override authorised)
- 8: Clock for switching Comfort → Standby (local override authorised)
- 9: Air quality information: enables you to send via the bus a "low air quality" signal to the room. An On-Off controller output
may be synchronised with this information.
- 10: Frost protection for "Fresh air": fan coil unit switched off, with hot valve 100 % opened
Note regarding D1 and D2:
- Make sure that the settings of inputs D1 and D2 are always different (to avoid any risk of conict between identical values on
two different inputs).
Parameters P51 or P52
Frame contact to be wired to input D1-C or D2-C, according to your device's conguration (refer to the corresponding wiring
diagram).

contact
The cable used has a maximum length of 10 m, and minimum section of 0.9 mm². It is recommended to use a twisted and shielded
cable.
Note: the window contact must be insulated from earth. If there is shielding present, it must be connected to the fan coil unit earth
- Direction of window contact
- If the window is open and the controller has a display terminal, this will display "_ _ _" instead of the temperature.
N.B: - When the window re-closes, the unit restarts automatically
- The terminal display will return to "normal" after 10 seconds, the synchronisation time between it and the controller
