Johnson Controls A19BAB-3 Penn Series 35°/95°F Coiled Bulb Open-High

The Johnson Controls A19BAB-3 Penn Series is an application specific thermostat ideal for use in heating and cooling systems. It runs within a temperature variation of 35°F to 95°F, thus fits most heating and cooling systems. This microprocessor based control unit is installed in a NEMA 1 type enclosure and consists of an air coil sensor element used to measure temperature changes. Functionally, the A19BAB-3 benefits from a single pole, single throw control output that turn ‘on’ or ‘off’ the circuit according to the set temperature point to maintain climate control.
