Commercial and Precision Thermostats

Honeywell Commercial and Precision Thermostats provide temperature control and over-temperature circuit protection by breaking the electrical contact when a specified temperature is reached. The Precision Thermostat line includes hermetic-sealed, non-hermetically-sealed, highly reliable aerospace and aviation versions, and pre-configured REDI-TEMP Thermostats. The snap-action Commercial Thermostats series features automatic and manual reset options, a phenolic or ceramic housing, and a variety of mounting brackets and terminal options. Honeywell Commercial and Precision Thermostats can also be integrated into higher value cable assemblies, incorporating wire harness and connectors.
