Thermostats
line Guide
Precision engineering. Commercial sense.
From the exacting
needs of high-end industrial and aerospace applications to
commercial safety and office equipment usage, Honeywell
Sensing and Control (S&C) thermostat solutions are the
recognized, respected leader. Both our commercial and precision
snap-action thermostats include automatic and manual reset
options, phenolic or ceramic housings and a wide variety of
mounting brackets and terminal options — while our precision
line includes both hermetic and non-hermetic devices. And
each thermostat’s design is configured from a base unit, and
can be customized for temperature tolerance and mechanical
configurations, meeting any of your needs for accuracy and
exactitude. It makes sense to trust industry-leading engineering
and innovation.
