Start-Up; Test Mode - Theben FCA 2 Manual

Fan Coil Actuator FCA 2

4 Start-up

4.1 Test mode

During initial operation (i.e. before the first download) the device is permanently in test mode.
Test mode serves to check the system, e.g. at start-up
or during troubleshooting.
In this mode, the valves and the fans can be set as required using the appropriate keys.
A temperature sensor (Order No. 907 0 321) or the window contacts can also be checked.
Important information about the test mode:
• Both the control and the bus telegrams are ineffective
• All settings are possible without any restriction.
• The valves are actuated until they are switched off again by hand.
• Condensate alarm is not taken into account
• The prevention of improper operating conditions (e.g. heating and cooling valves are
open simultaneously) lies in the responsibility of the user.
Allow / suppress test mode:
The test mode is allowed or suppressed via the Test mode after reset parameter on the General
parameter page.
Activate test mode:
Trigger Reset, i.e. via download or applying bus voltage:
 The test mode LED flashes for 1 minute.
During this time, the test mode can be started by pressing the valve / or fan button
 The FCA 2 switches to test mode and the "test" LED is permanently illuminated.
End test mode
Test mode is ended:
- by simultaneously pressing both buttons (A+B)
- by downloading the application (parameter Test mode after Reset = blocked)
If no button is pressed while the test mode LED is flashing, the FCA 2 automatically moves
to normal operation after one minute.
At initial operation, i.e. no application program, the LED flashes without time limit.
