Thank you for this information, very useful as the potential difference is (as you say) related to the resistance on the circuit. I have checked the status of each zone using the A? command in the comfigurator UCM I/O window, and I have a question to ask and an observation to make.

1) I can get readings on Comfort and Slaves (Zones 1-8; 17-24; 33-40; 49-56) with all hex results in 63-65 range, so this is useful to check on the health of these zones. However, you said that the LEMs cannot be read in this way (not analogue?). I have found that for the four LEMs involved (32 zones) they do give a reading (60). In one case however (window sensor) it gave a 70. When I investigated the sensor a bit it came back to 60. Question: Are the LEMs reporting a level (in increments of 10?) to Comfort and if so how does each relate to the analogue scale? If they are reporting on some scale or other, even the LEMs could be interrogated for zone wiring health.

2) In Comfigurator in the Zone/Inputs window if "module status" is set to "on", normally the on/off indication for each zone is reported. I see that when I interrogated Comfort with the A? command for each zone, the decimal value of the zone replaced the "On/Off" indication (e.g. "off" is replaced by "101"). This is very useful, but it also suggests that Comfigurator could be used to monitor/report zone health. Once I understand the LEM behaviour more, I will make some suggestions.

Thanks
