You’ll probably find that the sensor positioning for the temperature pick up are in different locations. The boiler stat can also be ‘modified’ to adjust to certain locations and of course finally, sensors can be inaccurate 

Most likely different temperature sensors between the IHD and your boiler remote. It happens. This won’t cause your meter to get messed up though - the temperature sensor in the IHD is only a guide. Nothing more, nothing less.

It could also be that they’re reading from different locations. Remember that heat rises, so it’s warmer higher up than lower down for the most part.

Yep well aware that heat rises .. I IHD is lower than the controller for my boiler.. Thought it was perhaps just meant to be a guide.. Just was curious why 2 degree difference. :) 

I’m curious that way .. lol

Do you find the temperature feature on the In Home Display helpful, @Amerififer? 

Am I right in thinking this feature is available in newer Chameleon IHD6’s @Blastoise186? Any other In Home Displays have this feature? 

The only Chameleon ones I know to have a temp sensor are the ivie Bud and the Chameleon IHD7 (including variants like the IHD7-CAD-PPMID and IHD7-CAD-PPMID-S1). I think I’ve also seen it on a few Geo and Hildebrand IHDs as well.

What I can confirm is that I’ve not seen it on the IHDL SmartView range.

IHD6 has a temperature reading .. well at least on mine it does 

Ah yeah, I forgot about those. It’s possible a few later ones had it after a hardware refresh.

Could you check under IHD Info for me as to what model you have?

IHD6-CAD-PPMID 

Thought so. That means you’ve probably got the hardware refreshed version :)
