Ranco A12 and A30 thermostats

[Timber]

Quick question , Is the cut-in adjustable on these ?

[pecmsg]

No Cut In is fixed, the dial adjusts the differential.

The cut-in can be adjusted with a tiny screw on the end of the stat. It was intended for an altitude adjustment, but you can use it to change the control. Just make sure you have a lot of time to kill!

Ya what he said. You can adjust cut out and cut in, but generally the cut in is 38 with the 1506, 41 with the 701.
