Johnson Controls A70BA-18 Temperature Control R-410A this assembly is a critical

this assembly is a critical fix for ignition problems or poor flame quality caused by oxidized or clogged ports

ensuring the combustion blower is generating sufficient negative pressure before allowing the ignition sequence to proceed

this start relay effectively manages the initial torque required by coordinating the start capacitor during the motor’s start-up phase

Key Benefits High-Precision Cutoff: Opens exactly at 218°F (104°C) to prevent terminal equipment failure during a rollout or overheating event

significantly reducing installation time for contractors

Johnson Controls A70BA-18 Temperature Control R-410A this assembly is a criticalThe 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
