Johnson Controls A70BA-18 Temperature Control R-410A this York HVAC furnace limitThe Johnson Controls A70BA 18 Temperature Control is a heavy duty low limit freeze protection thermostat engineered for critical refrigeration and heating applications. Designed with a single pole, single throw (SPST) contact structure, this "Open Low" control is specifically built to protect HVAC coils from freezing by opening the circuit when the sensed temperature drops to the user defined setpoint. With a temperature range of 15F to 55F and a
