Monitor batteries
The battery-powered devices (room unit, room temperature sensor, meteo
sensor, radiator control actuator, door / window contact and smoke detector)
constantly monitor their batteries’ capacity. If batteries are low, a message is
forwarded to the central apartment unit.
In that case, the central apartment unit switches from the quiescent picture to
info page “Device state“ to show the device with the exhausted batteries
(provided there is no more severe fault). After a certain period of time, the
display will return to the quiescent picture and show the error symbol
.
On the battery-powered devices themselves – with the exception of the room
unit, the door / window contact and the smoke detector – the result of auto-
matic battery monitoring is not displayed.
Room unit QAW910
The room unit indicates when its batteries are close to exhaustion.
If the batteries are exhausted in
about 3 months’ time, the “low“ sym-
bol is displayed.
Door / window contact wave AP 260
If batteries must be replaced, the LED will briefly flash every 10 seconds.
DELTA reflex smoke detector
If batteries must be replaced, the LED will briefly flash 3 times every 48 sec-
onds and a short acoustic signal is given.
Manual capacity check
With the room temperature sensor, the meteo sensor and the radiator control
actuator, battery capacity is also checked when a binding test is made (refer
to page 90).
If, during the binding test, the green LED of the respective device is lit, battery
capacity is sufficient.
If, during the binding test, the red LED of the respective device is lit or is dark,
battery capacity is insufficient.
