The Johnson Control’s A421 digital temperature controller is great for the brewers kegerator or keezer. You can use this to keep your beer or wine at exactly the temperature you like it. Excellent for fermenting lagers as well. The A421 Series controls are single stage, electronic temperature controls with a single-pole, double-throw (SPDT) output relay. The controls feature an adjustable backlit LCD for viewing the temperature and status of other functions, and a three-button touchpad for setup and adjustment. An LED indicates the On/Off status of the output relay. The A421 control is 120 VAC. The A421 controls provide heating or cooling control, sensor offset, temperature setback, adjustable anti-short cycle delay, and a restricted user adjustment mode. The temperature units can be displayed in °F or °C. The temperature adjustment range is -40 to 212°F or -40 to 100°C. The A421 automatically changes from heating and cooling.

This is an AC 110V Fahrenheit Digital temperature controller. It can control the power to a freezer to prevent it from getting too cold, or control the power to a terrarium to prevent it from getting too hot, maintain a stable environment.

This controller provides heating and cooling modes and temperature alarm function.
For example:
If you choose heating mode, set control Value to 100°F, set span value to 10°F. The relay will be connected when temp drop to 90°F. The relay will be disconnected when temp reaches 100°F;
If you choose cooling mode, set control Value to 100°F, set span value to 8°F. The relay will be connected when temp reaches 108°F. The relay will be disconnected when temp drops to 100°F

The WH1436 temperature controller can turn on/off an electric appliances at desired temperature.
For example, you can use the controller to turn on a heater at 99.9 F and turn it off at 100 F. Or turn on a freeze at 52 F and turn it off at 45.3 F.
(Please be noted that the controller itself doesn’t change temp. You need to use heater or refrigeration equipment with it.)

Main features:
1-YEAR WARRANTY: From the date of purchase.
Plug and play. No worry about wiring.
