Hi to all.
I am new for this forum. I checked if there was a similar post but could not find it.
Ok now the problem.
I have built a Open Gateway kit and all the (not connected boiler and thermostat) tests were succesfull.
When I connected only the thermostat (Honeywell Chronotherm Vision modulation) the display comes up with connection error (aansluitfout).
The thermostat supply is in accordance with spec (6.7 V).

Running diagnostic (V1.1) with only thermostat connected give for

test 2 a lot of numbers
00030000 Read-Data Slave configuration: 00000000 0
510,1004,508,500,508,500,509,499,509,499,508,500,508,500,509,499,511,499,509,499,509,500,508,500,509,500,508,500,1012,500,509,1006,508,499,509,499,508,499,509,499,509,500,509,499,509,500,511,499,509,499,509,499,509,500,509,499,509,499,509,500,508,500,1007.

Enter test number: 5
Thermostat: 0.79, 2.12
Boiler: 0.00
Reference: 1.22

Anyone an idea were to look or what to do

regards
Piet

by connecting the boiler too the connection error disappeared and there was a normal view on the display.

So error solved continue with testing the next steps.

There was no error. Everything you reported was exactly as expected.
