Replacement cabled Vantage Pro2 Integrated Sensor Suite (ISS) PCB which includes the rear plastic mounting case. Suitable for worldwide use and a replacement for the earlier part number 7345.977 (note below). Not suitable for wireless models or the original Pro weather station (pre 2006).
Suitable for all cabled sensor suites manufactured after January 2009 (see Mfg code on existing ISS transmitter label).
Using a post December 2015 transmitter with your original temperature / humidity sensor will result in the temperature reading 0.5C (0.9F) low. To counteract this error a calibration offset should be applied in the console to increase the temperature by 0.5C (see page 26 of your console manual for calibration details).
If you are using a new temperature and humidity sensor then no offset is required.
