Evohome how to fit HR92s to Giacomini TRVs

[Ubernoob]

Hi,

I have an Evhome system setup with my heat only boiler / vented cylinder, to date I have 3 x HR92s but am building my system. Has anyone been able to fit the HR92s to Giacomini's TRVs (see link below)? The thermostatic head has a clip on system to the TRV valve. I have tried using the collar that cam with the HR92 but the shaft inside does not seem long enough to push down the TRV.

Any thoughts (thanks in advance).

For the sake of £9 per rad and 10 minutes of a plumbers time I would strongly suggest replacing the radiator valves with Honeywell ones.
