For heaters manufactured since February 2010 all Heatsource product have been fitted with an integrated air flow sensing device from Omron.  This is a new MEMS D6F air mass sensor and, importantly,  works with no moving parts.  This has overcome an issue in older heaters where, if left unused for long periods or subject to a very hostile environment, the spinning wheel sensor may become sluggish and not want to spin up.  This kit allows the Omron sensor to be retroffited into the older models including the HS1600, HS1800, Pre Feb 2010 HS2000  and the HS2800 and so doing away with the Air flow sensing fan and infrared detector.  The fault is displayed on the thermostat as a five flash code
