I changed from a T80 to a T100 HTM last winter
realy easy to do all you have to do is remove the extra wires from the T100 loom for the temp sensor and fit to your existing one everything else is identical
I have the timer but never ever use it as the T100HTM includes a predictive timer as well, you tell it what time you are leaving and it works out when it needs to switch on
I then sold the T80 on here
