a) "FHT8R" heating control

If the battery symbol ("
the battery voltage is low and they have to be replaced.
In addition, the heating control generates an acoustic alarm
every 2 minutes.
At night the acoustic alarm is not generated, but only during
the following three periods of time:
- from 10.00 hrs to 11.00 hrs
- from 17.00 hrs to 18.00 hrs
- from 21.00 hrs to 22.00 hrs
Proceed as follows to replace the batteries:
• Take the heating control off the wall holder and open the
cover of the battery compartment (slide down).
• Remove the empty batteries from the battery compart-
ment and dispose of them according to applicable envi-
ronmental regulations
• Insert two new AA batteries; pay attention to the correct
polarity. If possible use alkaline batteries.
• Close the battery compartment.
• Like during first commissioning the heating control asks
you to enter date and time.
• However, the settings of the time program, the comfort/
lowering temperature, etc., have been maintained.
• Since the heating control and the valve operating mecha-
nisms are no longer synchonised after a battery replace-
ment the heating control performs an automatic synchro-
nisation that takes about 2 minutes ("SYnc Auto").
After the synchronisation the heating control returns to
the normal operating mode.
