Horstmann HRT4-ZW thermostat and UI3

Since upgrading to UI5 I can’t get my Horstamnn HRT4-ZWA thermostat paired with my Vera2. Vera simply just does not see the thermostat anymore.

Any one has a clue on how to solve this?

Did you exclude (unpair) the thermostat first?

I double clicked P until PP appeared yes.

Suggest you exclude the ASR with the HRT and next exclude the HRT with Vera.
Then go ahead according to the process decribed here: http://forum.micasaverde.com/index.php/topic,4575.120.html
