BAS 918S/929S Manual Introduction: Thank you for choosing a BAS 918S/929S controller. Please make sure that you have received the correct controller version and all the materials included. The difference between the two controllers are only the supported I/O. Please look at the following illustrations.
Produkt front 4 pcs. of , 3.9mm x 32 mm screws for wall mount Cable relief bracket for cable retention at socket 2 pcs. of 3.0mm x 8 mm screws for cable relief bracket mounting (4) BA Systems—Petershvilevej 1—DK-3200 Helsinge—http://www.basystems.dk...
Use a sharp knife to cut the plastic along or within the lines of the markings. When cutout is made in the connector end of the front, cables are inserted here and may be retained in the socket using the cable releif bracket. BA Systems—Petershvilevej 1—DK-3200 Helsinge—http://www.basystems.dk...
Generic socket connections are defined in placement and function in the following draw- ings and descriptions. This indicates the maximum I/O configuration for the BAS9XXS controller. Please note that the variant you have bought may have reduced configuration. BA Systems—Petershvilevej 1—DK-3200 Helsinge—http://www.basystems.dk...

An advantage of this is that there is only one common reference. As shown above, a 5 wire cable is sufficient for connection to 4 pcs of thermal sensors. Please note though, that sensor calibration is recommended because of increased voltage drop over the common reference. BA Systems—Petershvilevej 1—DK-3200 Helsinge—http://www.basystems.dk...
