Hey all,
I want to buy a Remeha Tzerra Plus boiler. Does it support OpenTherm ID 18 'CH water pressure'?

According to the boiler information table at http://otgw.tclcode.com/matrix.cgi#boilers, the Tzerra does not support ID18.

I know, but I suspect al lot of these logs are incomplete. If the thermostat doesn't support the DataID the boiler isn't queried. I see OT Monitor does send the DataID 18 so it should have been marked with a cross if the boiler responded with an Unknown-DataID message, otherwise it should have been marked with a bullet.D_Hailsham wrote:According to the boiler information table at http://otgw.tclcode.com/matrix.cgi#boilers, the Tzerra does not support ID18.
Clarification of the tables
- A bullet (●) next to a DataID in the thermostats table means the thermostat has been observed to send the specified DataID.
- A bullet (●) next to a DataID in the boilers table means the boiler responded with a Read-Ack or Write-Ack message to a request from the thermostat for the corresponding DataID.
- A cross (×) means the boiler responded with an Unknown-DataID message to a request from the thermostat for the corresponding DataID.
- A question mark (?) indicates that logs have been uploaded with conflicting results for the DataID.
- If there are very few bullets listed for a boiler, that does not necessarily mean that the boiler has very limited Opentherm support. If there are also very few crosses, the boiler was probably used with a thermostat that doesn't send many different Opentherm DataID's. Only a large number of crosses indicates poor Opentherm support by the boiler.

Enigma solved.
The boiler returns a Data-Invalid message.
