Secware Posted October 10, 2011 Share Posted October 10, 2011 I bought a new DT7550UK2 from you last week to replace an existing faulty one. The existing one is a DT7550UK so assume this must be the older version. Looking at the existing wiring, it is wired as follows F1 - empty F2 - empty T1 - resistor to C T2 - yellow C - resistor back to T1 and to NC EOL - empty NC - resistor to C and blue V- - black V+ - Red Both resistors have the following bands (Brown, Black, Black, Brown, Brown) or I guess could be (Brown, Brown, Black, Black, Brown)? Looking at the installation instructions for the new one, it implies I should not use the existing resistors and wire up as above. Is this the case? Also, will the factory jumper settings we ok?
