The indicating mechanical temperature controllers are self-operating, requiring no operating power. On-off controllers are available with one or two switches, for heating, cooling, or heat-cool applications. Proportional units are for use with position proportioning motors, pneumatic devices, or provide time proportioning outputs. Some controllers have dual setpoints for alarming or auxiliary heating.
The mechanical, non-indicating, temperature controllers are self-operating, on-off controllers for use in a wide variety of applications. They provide simple control and require no operating power.
