Hello!
my first post to the forum, and im afraid its a problem - sigh..... So I have had the evo home system installed for about 4 months and then all of a sudden I noticed that I could not override the temperature in my study, for some reason it is just not calling for the heating to turn on. The installer came out but basically had to leave after 4 hrs and to be honest got really fed up with having to wait every 4 minute. He called up Honeywell who told him it was interference by the WLAN or the computer in the study - which it is not, as I have turned all this off to prove it... so I have a few questions...
1) What is the actual message flow from the HR92 to make the heating turn on, for example...
---- Radiator valve has override set and opens the valve
---- Radiator valve sends packet / message to evohome controller - controller updates display showing new overridden temperature
---- Controller then sends packet/ message to the Heating Relay? Is there an ACK sent to the rad valve etc?
---- Heating relay turns opens valves, turns on pump, fires up boiler etc?
are there any acknowledgements or messages sent between these processes? Do all the messages go to the evohome controller, and then this in turn sends the required message to the relay etc?? I have searched and searched for this but cant find the information
2) In my scenario I have tested the radiator valve to the controller = 4/5 signal on all tests - it actually updates the value on the evohome controllers screen
3) I have tested the evohome controller to the HR91 relay, 5 flashing red lights....
4) I have used the phone app to change the value in the office, the evo home controller updates the display showing the new value, the new value gets sent to the radiator valve and is updated.
5) The radiator valve can talk to the evohome controller (as proved in step 2), the evohome controller can talk to the HR91 (as proved in step 3).....
5) ALL the other zones work fine, I can override them - heating turns on - I can use controller to change temp - heating turns on - I can use phone app - heating turns on.
5) why oh why is it not working for the study zone!
Any help really appreciated, its driving me nuts.. I have properly removed the binding, deleted the zone and rebound and STILL the same problem - I just don't get it... There are also no fault logs at all for COMMS etc etc!
