The TC-5231, TC-5232, and TC-5241 low temperature 
thermostats are used to control temperature in air 
conditioning or refrigeration systems. The low 
temperature thermostat measures the coldest one-foot 
section along the entire 20-foot sensing element.

The low temperature thermostats are applicable to 
various applications such as: low temperature control 
of steam coils; frost indication in storehouses or 
orchards; temperature control of freezer cabinets, 
display cases, beverage coolers, milk cooling tanks, 
and air conditioners.

Features

20 ft. (6.1 m) element senses temperature over a 
large area. Control responds to coldest one-foot 
section of the sensor.

Adjustable setpoint from 35 to 60°F (1.7 to 15.5°C) 
with 5°F (3°C) fixed differential.

SPDT and DPST versions.

Rated for use at 17 full load amps (120/208/240 
Vac), 24 non-inductive amps (120/208/240 Vac), 
and 16 non-inductive amps (24 Vac). Capable of
