[Trace-users] Control Panel & Interlocks

[Oscar Buchely]

Hello Mike

I had the same problem. The reviewer asked me why I got electric 
consumption for a gas boiler. In the reply I explained him about the 
interlock component and it was fine.
After that question I always  deleted the interlock component so I don´t 
get any comments on that. I don´t think is a good idea to put them as 
process load because its part of the hot water system.
