If the heating has been switched on via this function, it may
occur that the automatic control switches the heating off
again. This may be due to an external signal, for example, or
because the desired temperature has been reached.
The heating can also be switched off by the control itself:
• by an external signal on the unit’s input, see
menu > Configurationmenu > Configuration > 60. Func-

Filter
Dirty filters make the unit less effective. It is therefore neces-
sary to clean or replace the filters at regular intervals. The
contamination of filters is measured with the optional filter
sensor or calculated on the basis of the lifespan.
The lifespan of the filter is calculated on the basis of the usage
of the unit if no filter sensor has been installed. You can adjust
this by setting the maximum lifespan of the filter.
When the filters are contaminated or when the maximum
lifespan has elapsed, a message appears on the Home screen.
Also, a signal can be generated on one of the outputs.
New filters are available from Biddle.
Cleaning the display
The screen can be cleaned using a damp, soft cloth.
Use this function to disable the touch screen for 20 seconds in
order to be able to clean it.
Timer
The b-touch control panel has a week timer. You can set two
start and stop times for each day of the week. The unit is on
between the start time and the stop time. The second start
and stop times are optional. When the ON/OFF button is dis-
played on the screen, the unit can also be switched ON or
OFF manually. From the next switching moment, the unit fol-
lows the timer again. When the timer is switched on, the sym-
bol
@
is displayed on the Home screen.
