activated since the last exercise. The pump is activated 3
minutes during the exercise.

been activated since the last exercise. The exercise consists of
opening and completely closing the actuators:
• 5 minutes to open an actuator
• 9 minutes to close an actuator

executes the fallback mode to maintain the temperature in the
room (heating or cooling) until the problem is resolved.In fallback
mode the actuators will be controlled as follows:
• 7 min open
• 14 min closed
If the wire is broken, the preceding thermostat in order control
the actuators. If this is not possible, the fallback mode will be
activated.
11.3.2 Resetting the controller
If the controller does not work as expected, for example due to a
hang-up, it can be reset to solve the problem:
