Stego Compact Thumbwheel Thermostats

Applications
Normally Closed (N.C.)
Normally Closed adjustable thermostats
have a red adjustment dial and contacts
that open when the air temperature rises
above the setpoint. Uses may include
regulating heaters or switching signal
devices when temperature falls below the
setpoint value.
Normally Open (N.O.)
Normally Open adjustable thermostats
have a blue adjustment dial and contacts
that close when the air temperature
rises above the setpoint. Uses may
include regulating cooling devices (heat
exchangers, lter fans vortex coolers,
etc), or switching signal devices when
temperature rises above the
setpoint value.
