Operating instructions for the

X2 operating system

The X2 operating system was designed for universal controllers and sensors. Devices based on the X2
operating system contain a multitude of standardized functions and application possibilities. From simple
ventilation controllers for domestic applications to HVAC system solutions for entire buildings. There is a
suitable solution for almost every application. With the EasySet program, the controllers can be conveniently
read out, programmed and transferred to other controllers.

Applications

These operating instructions apply to devices of the X2 series with integrated control unit, as well as to devices of the
OPA2 and OPU2 series.

Idle Display

• The idle display is activated when no key has been pressed for 30 seconds.

• The idle display can be deactivated by the technician. Last active control loop or manual output will remain displayed.

Display of control loop

• Active when changing set points. Large digits show input value. Small digits show set point. Horizontal bars top left

show which loop is being displayed.

Override of secondary set point in cascade control

• With cascade control, manual override of the secondary circuit can be activated. This is defined by the technician in

the controller settings.

• If cascade control is active (with VAV for example) the user can override the primary loop and manually select the set

point of the secondary loop (the loop is then changed to constant air volume mode). This function is helpful for tuning
the VAV system. While the secondary loop is displayed change the set point with UP/DOWN. The hand symbol
appears. Change setpoint again to cancel cascade override. The hand symbol disappears.

Manual Mode

• The hand symbol is displayed during a pending delay. For example, if a start -up delay is active. The controller

remains switched off and displays the hand symbol until the delay has elapsed. Then the controller switches on and
the hand symbol goes out.

Status-LED

• A status LED is located on the upper left side of the controller housing. During normal operation the LED blinks

briefly once every 5 seconds. It will blink every second in case there is an alarm or fault condition.

Power Failure

• All parameters and set points are memorized and do not need to be re -entered. The switch-on behaviour on return

of the power supply is set by the technician.

• Clock and time schedule settings are retained for 48 hours after being powered for at least 10 hours.

Error Messages

Err1: Communication error
Err2: Internal error: Firmware version of the memory does not match firmware.
Err3: Timer error: Set time and acknowledge error. If an error occurs again at a previously set time, the watch is

faulty. Time switching functions are not guaranteed in this case.

Err4: Configuration error: An assigned input is not activated or has failed. Check all settings and ensure that all

inputs used are activated and functional.
Err5: Copy error: Communication error with external memory AEC-PM1 or AEC-PM2.
Err6: Copy error: Checksums of the data record are incorrect. The data record is invalid .
