Wireless small actuator operating modes
!
NOTICE
All operating modes including self-controlled mode and frost protection function become available
after startup, i.e. after successful teach-in on a radio partner
Actuator mode
If a 0 to 100% EnOcean telegram is received from an external radio partner for controlling the radio
small actuator, the internal loop controller is not active.
The transmitted actuating signal is translated into a positioning movement.
A suitable radio single room controller takes over the control functions.
Self-controlling operation
The integrated room temperature controller is activated if no external 0 to 100%
EnOcean radio telegram is received.
- Without external operator panel (= emergency mode):
The temperature is controlled to a fixed setpoint of 20 °C using the integrated temperature sensor
(actual value) and the integrated control function of the actuator.
- With external operator panel (EnOcean technology):
Using the operator panel, the users can freely determine the setpoint or enter their own schedule.
The actual value and the setpoint are transmitted via an EnOcean telegram (EEP A5-20-01).
The integrated control algorithm makes room control easy and convenient.
Battery monitoring
The battery capacity is continuously monitored. If the battery capacity is too low, a radio signal is
transmitted to the radio partner and 2 acoustic signal tones are emitted in succession every 6 hours.
If this message is activated, the remaining capacity of the batteries is < 10%.
!
NOTICE
The batteries must be replaced within the next 30 days.
As the battery level decreases, the interval between the audible signals becomes shorter and the
number of signal tones increases to 4 signal tones in succession every 3 hours.
If the remaining battery capacity is insufficient to maintain motorized operation, the actuator moves
into the safety position of 50%.
The radio communication with the radio partner still functions in this operating state.
