Caution!
Under the most unfavorable conditions, the signals from the extension
modules to the LMS14..., and vice versa, may take up to 40 seconds to be
refreshed in the LMS14… via the BSB. This can lead to functional restrictions
and detrimental effects on the limit thermostat functions. For such functions,
use BX1, BX2, BX3 or BX4.
Note!
Sensor input BX4 is firmly assigned to sensor B7.
