Connect the Local / Remote / BMS 0-10V control to “0-10V Input, Sensor One“ (J3 pin 3) and “0V“ (J3 pin 6). The external signal 0-10V signal will then control the fan speed over the 0-10V fan speed control voltage range. For local manual control an ebm-papst RM-ECv is recommended. 210-OMI13277_Iss1.doc... - Page 8 To invert Speed Control Output (Heating Profile), make S2 setting higher than S3 setting, set S2 to the maximum speed and S3 to the minimum speed. 210-OMI13277_Iss1.doc ORIGINAL INSTRUCTIONS Page 8 of 15 © ebm-papst UK Ltd, 2012 Chelmsford Business Park Chelmsford Essex CM2 5EZ Telephone: +44(0)1245468555 Fax: +44(0)1245466336 e-mail sales@uk.ebmpapst.com...
