Opentherm gateway and Vokera Unica HE

[david_wallis]

Hi,

I have built the gateway and connected it to my boiler, at the moment I don't have an opentherm thermostat.. Seem to be in short supply in the UK at a sensible price.

My plan was to wire the original thermostat into the opentherm board initially, but allowing me to monitor when the boiler is coming on etc.

When connected the boiler it is recognised and its two seven segment displays change to ot

however Shorting the cables has no effect on firing the boiler up... (it does recognise it on the log.)

here is the log:

[hvxl]

what should I try next?

Firmware 4.2

[david_wallis]

Thanks, I thought I was on the latest firmware, but looking at the release date, I was at the time when I last tried, so didnt think to check for another release..

Just upgraded to that and it still doesn't fire..

logs show the version change too.

Looks to me like the gateway is now doing what it is supposed to do. Starting at 10:59:32 it sends the CH enable bit in the status message and a control setpoint of 80 degrees. According to the opentherm specification that should cause the boiler to start heating. But then at 10:59:56 it falls back to the idle state. At 11:00:06 it tells the boiler to start heating again. Did you manually short the wires, or did you use an actual thermostat?

Perhaps you need to give the system some time. If the boiler was heating just before you connected the OTGW, it may have some internal timers that prevent it from heating again within some set time after its previous cycle. According to the manual this is "at least 3-minutes after the set-point hysterisis (set-point + 5-deg)". The on/off/on cycle you did may have restarted the timer. So you may have to be a bit more patient.

The manual also shows that the boiler uses different connecting points for an on/off thermostat and an opentherm thermostat. Perhaps it sticks to one or the other once it has seen one. You could try to power-cycle the boiler and then make sure the on/off thermostat doesn't interact with the boiler (disconnect it, or set it very low).

Finally, if you're unlucky, the boiler may not properly follow the opentherm spec and will only work with a specific thermostat that sends some non-standard opentherm messages to make the boiler operate.

Tried Disconnecting std thermostat, power cycling boiler and leaving a while.. no luck.

Then your boiler wants to see something more/different from what the specs prescribe. Someone else reported that his boiler operates based on the current room temperature and the room setpoint. If you're up to it, you can try to use the interface firmware to send your own messages and figure out what the boiler wants to see.

You can also try to contact the manufacturer, but experience of several people shows that most of them are not able/willing to provide such details.
