Manual Thermostat Control Unit


Convert any freezer into a kegerator! Just plug the freezer into the outlet cord, place the gas-filled sensor in the area to be controlled and program the temperature. This manual thermostat simply turns off the freezer when it reaches the specified temperature. Other features include rotary dial temperature adjustment, a 6-foot power cord and a 6-foot outlet cord.

The A19AAT type thermostats are single-stage cooling controls with Single-Pole, Single-Throw (SPST) switches that open on temperature drop.

The A19AAT type thermostats are designed to override on-board refrigerator thermostats and provide accurate temperature control outside of the range of the on-board thermostats.

The A19AAT-2 model thermostat has an adjustable 20 to 80°F (-7 to 27°C) set point range, a fixed differential, and is enclosed in a rugged steel NEMA 1 enclosure.

Great thermostat for deep freeze
by:BoycoCmd (03-30-2016)

Comments:This is my 2nd Johnson control thermostat in 8yrs. I just gave my 1st one to my dad after the 3rd time he has borrowed it. We process our own beef on our small family farm and use these thermostats to convert our large chest freezers into refrigeration units to store fresh beef up to 2 weeks to age the meat. My older thermostat has worked flawlessly and accurately (storing meat right now at 30┬░f. as does my new one. Great device!
Bottom Line:I would recommend this product.

Comments:Easy to use and easy to set. Dail temp and measured temp differ by several degrees. I have the thermostat prop in a mason jar of h20 at the bottom of the cooler. When setting up us a thermometer in the jar of h2O until you find your desired temp. Note the tamp on the dial of controller.
Bottom Line:I would recommend this product.

What is the purpose of the remote sensor bulb on the A19AAT type cooling thremostat?
by cheese lady on March 04, 2019
The remote sensor is what is going to relay the temp of the unit to the controller and if the set point is passed it will turn the whole unit off and stop cooling.
