No signal from boiler
Posted: Mon May 06, 2013 4:55 pm
I bought an assembled opentherm gateway (http://www.opentherm-gateway.com/openthem-gateways.html, the USB version) but sofar I failed in receiving data from the boiler. I tested the gateway with two boilers (remeha quinte and intergas) and three thermostats (two remeha celcia 20 and one honeywell round modulation).
This is my result when following the troubleshooting starting at slave interface (http://www.tclcode.com/opentherm/debugging.html)
- After connecting the thermostat to the gateway I see the expected T80190000 messages in the opentherm monitor program
- After connecting the boiler to the gateway does not give the expected result (messages from the boiler).
- The GW=0 command didn't give any data
How to proceed?
Best regards,
Pieter
