Question on etc and 0-10 Vdc
I see some posts concerning 0 -10 control signal . I have not dug into to deep and most I know could care less but here it goes . Can u use say a ranco etc w a 0 -10 signal out put to control say a variable speed pump or a control valve which would have a fixed set point . Not talking about any type of temp reset just for controlling a set point . I use these instead of aquastat on indirects usually for service and installs and always think what other good can be accomplished w this little device and its control sign hum . Just wondering if anybody out there has looked in other possibilities for applications utilizing its signal output . I always had great luck w etc in refrigeration where they are used a lot but not much on the heating side especially when it’s hydro air .i ve of course seen it used commercial but mostly as on off and not much more . Any thoughts peace and good luck clammy
