Description

Features and benefits

Control front panel LCD

Displays the temperature, parameters, and status. You can adjust the backlight intensity for ambient light conditions. Custom icons display the system and control status.

Basic and Advanced programming menu

Provides two levels of parameter adjustment and control. You can set up advanced features in one menu and easily adjust basic parameters in the other menu.

On/Off temperature adjustment

Select the temperature values at which the relay turns On and Off, which automatically defines the Heating or Cooling mode of operation.

Switch-activated temperature setback

Shift the On or Off temperature by an adjustable setback value. When a user-supplied switch closes the binary input control circuit, the control operates at the defined setback temperatures.

Adjustable anti-short cycle delay

Select the minimum time the output relay remains off before the next on cycle; avoiding short cycling, hard starts, and nuisance overload outages on compressors and other inductive applications.

Adjustable sensor offset

Adjust the displayed temperature to the actual sensed temperature.

Optional restricted adjustment mode

Restrict the On or Off adjustment to your defined temperature range.

Sensor failure mode

Select the relay On or Off state in the event of a sensor or sensor wire failure.

Backlight brightness level

Adjust the LCD backlight intensity.

So easy to use

I like this A421AEC-02C single stage temperature controller because it just performs well. I can see where things are going within the device thanks to its LCD screen. The menu contains at least two levels of controls so I could easily adjust its settings. It is durable thanks to its electronically insulated wires, which are built for high voltage 120/240 VAC models like the ones used in my fridge. In fact, I bought a few of these temperature controllers not only because I do own a fridge, but also a few air conditioners to combat the summer heat outside. It pays to have something smart to control them. Highly recommended.

Reliable & durable temperature controller

I first saw this temperature controller when I was planning to upgrade my own heat system inside the house. It is single staged, and can handle temperatures from as low as -40 to as high as 212 degrees Fahrenheit. For those more used to the Celsius measurement, theres an option for it too. Im also glad to see that it is electronically insulated so it can tolerate such range in heat. Of course, it comes with an adjustable LCD screen so I can easily view the temperature and the status of its functions. The A421AEC-02C is reliable, durable, and worth buying.
