Re: Opentherm Gateway 4.0 alpha/beta testers wanted

According to the equipment matrix, the TF30 never asks for a setpoint override (MsgID 9). Starting to learn more and more. Did not realise the thermostat was leading, not the boiler. So that means that the gateway mode is useless for this thermostat and monitor mode is what I should use (monitor is...

Appologies, thought the boiler was leading... :? I am using the Bosch TF30 as thermostat.

Re: Opentherm Gateway 4.0 alpha/beta testers wanted

Verry hot this morning in my house... The communication stalled from my thermostat (Error 01) and the right temperature was not sent to the boiler so it kept on heating. Changing from gateway to monitor restored the communication and put the boiler on ease. (Perhaps a future failsave option in OTG?)...

Re: Opentherm Gateway 4.0 alpha/beta testers wanted

Using Bosch HRC 30 I have many Error 01 (about once a sec) with 3.4 in GW mode. Just upgrade the OTG to 4.0b3. After the upgrade the Diagmostic window only showed a Txxxxx message and underneath Error 01. Over and over again, nothing else so all communication failed. Then I checked the option Tools ...

Re: Bosch: Error 01 looking for VR=2.5

After 3 weeks running (can see the boiler temp, flame status, DHW, not able to set anything yet - using VeraLite) I installed the Diagnostic firmware. Used the bit test #2 where the thermostat quite often fails with the only last byte < 900 (but close), the boiler interface #3 is al lot of red, lots...

Bosch: Error 01 looking for VR=2.5

I'm using the Bosch TF30 and HRC 30 with OTG. Unfortunately the OTG gives a lot of Error 01 @ VR=3 already whith the initial testing (http://otgw.tclcode.com/debugging.html#slave). Setting the value VR=2 fixed the problem however after a while the communication was stopped completely. So perhaps the...
