Hello everyone, I've just recently had a Room Humidity Sensor throw an alarm in insight as "FAILED". I contacted a local dealer and told them that I needed a replacement for a two wire Siemens Humidity Sensor PN# 544808A. He said my old sensor needed to be replaced with a Siemens QFA3001.BU. The problem I have is that I don't have the knowledge to know exactly what terminals the wires go to. Here is the link for the installation instructions. http://w3.usa.siemens.com/buildingte...ts/129-505.pdf I've also attatched the pdf for the Humidity sensor. The link shows the terminal block on page 2. I'm thinking terminals 9 & 2 but am unsure. If there is someone who has knowledge in this area could you help out? AttachmentRHT.pdf (808 Downloads) |
