Low Temperature Thermostats
The TC-5231, TC-5232, and TC-5241 low temperature
thermostats are used to control temperature in air
conditioning or refrigeration systems.
Features:
• 20 ft. (6.1 m) element senses temperature over a large area.
Control responds to coldest one-foot section of the sendor.
• Adjustable setpoint with 5 F degrees (3 C degrees) fixed
differential.
• SPST, SPDT and DPST versions.
• Capillary mounting clips provided.
