The wires of the weather sensor may not be properly grounded. When the rain sensor is activated, the LED light will light up. This activates a 15 minute timer that can be reactivated by rain or wind. During this period, the ventilation mode cannot be used. Also check that terminals 21-22 are not short-circuited, which could be caused by a clock, building alarm or CTS.

If LED light 4 is on continuously: there is a problem with the actuator. This can be caused by an incorrect connection or because no resistor has been installed.
If LED light 4 is flashing: there is a problem with a wire that connects to the mass. Note: this can cause the limit switch to break.

• J2-J3 is not set correctly
• Output fuse defective (8 A fuse)

Correct functioning

Alarm: the opening system is open (indicated by LED 1)
Reset: the opening system is closed (indicated by LED 2)

Regarding the fire push button:

• The 10KΩ resistor in terminals 13-14 must be removed when the fire push button is installed.
• J1 in the fire push button is not installed.
• The wires are not placed correctly.
• J1 must be “ON” only in the last (or only) fire push button. This is the correct setting for the fire push button.

Regarding the priority switch:

• There is an incorrect connection. Check the attached diagram for the correct order.
• The resistors on terminals 24-25 to 27 are not removed.

• Wires are not connected properly to the detector.
• Detector not correctly “clicked” (turned) into the contact
• Resistor 10K missing in the last detector

• Make sure the 230 V fuse in the control panel is switched on.
• Check if the power supply under the main PCB is defective. A green LED light should always be lit on the power supply behind the PCB.

• Check the internal LED lights on the main PCB to determine which output or input is giving a line fault.
• Make sure the ribbon cable from the hood is connected correctly (with the sticker facing right) or that the jumper is set to "No Foil" correctly.

• First check the connections on each fire push button or detector to make sure they are installed correctly.
• Then check if the connector cables in connection 16-17 and 13-14 do not touch each other.

Make sure that you always have a NO contact on external connections and that there is a 10k resistor in parallel. Also check that external systems do not transmit an alarm status.

The Snitch function (DIP5) is enabled. To solve this problem, reset the function by first turning DIP5 OFF and then turning it ON again.

If a control unit shows an error, but still shows a green "OK" LED, this usually means: "I am functioning fine, the problem is probably with another control unit that is also connected to the connector." Please note: by default, DIP5 is set to "OFF".
