Electric Operators
Communication test
A communication test can be started manually by pressing the button located under the hood.
Pressing this button (approx. 2 s) checks the signal path to the wireless partner saved in the device. A successful
communication test is visually acknowledged (by the status LED) and acoustically acknowledged after the
pushbutton is released. The status LED lights up for approx. 3 s.
An unsuccessful communication test is signaled by rapid blinking of the status LED for approx. 3 s.
Energy block (automatic “Window open” recognition)
When a window is open, the flow of heat energy to the room is interrupted. An open window is signified by a
large and rapid temperature drop at the MAC-WSA small actuator. If such a drop is measured by the internal
temperature sensor, the small actuator closes the valve for 30 min.
After 30 min, the small actuator returns to normal operation and the energy block function is active again.
Frost protection function
If the temperature at the integrated temperature sensors drops below 43 °F, the small actuator opens the valve
until 48 °F is reached.
Wireless Interface
Communication with the wireless partner is cyclical (wireless cycle approx. every 10 minutes). At this time, the
entire wireless protocol is sent to the wireless partner and values are received from the wireless partner.
NOTICE
This product uses only EnOcean radiograms.
When choosing a wireless partner, make sure that the wireless interface works with EnOcean radiograms and
that the wireless actuators being controlled support the particular heating valve standard actuator profile (EEP
07-20-01).
