Description
The Johnson Controls A19ABC-39 is an adjustable differential thermostat that will help maintain temperature in your HVAC system. It has an SPDT switch to initiate heating or cooling at a user’s preference or the current temperature of the environment. The main control unit with durable plastic housing helps you to set the desired temperature and change the range of the temperature difference from 3°C to 14°C. This differential setting defines how much the temperature changes before the thermostat makes a switch, thus avoiding the unnecessary cycling between on and off and therefore saving on energy. Due to its flexibility, this can be used in quite a lot of HVAC equipment, including boilers, furnaces, air conditioners, and ventilation.
