Description
The Johnson Controls A19ZBC-6 is a heavy-duty utility thermostat engineered for reliable temperature control across a wide range of commercial and industrial HVAC applications. Featuring a remote bulb sensing element with a 5-foot capillary tube, this thermostat accurately monitors temperatures at a distance from the control unit, making it ideal for duct, pipe, or space sensing installations.
Key Features
- Wide voltage compatibility: 120/208/240 Vac for flexible installation across single- and multi-phase systems
- Temperature sensing range of 0°F to 70°F for low-temperature monitoring and control
- Adjustable differential temperature range of 12°F to 40°F for precise switching hysteresis
- SPDT (Single-Pole, Double-Throw) switching action supports both heating and cooling control circuits
- 5-foot capillary length with remote bulb sensing element for accurate remote temperature measurement
- Automatic reset operation — restores normal function once temperature returns within set range
- Convenient dial adjustment for easy on-site setpoint configuration
Application
The A19ZBC-6 is well-suited for freeze protection, refrigeration, ventilation, and general-purpose temperature switching in commercial and light industrial environments. The remote bulb design allows the sensing element to be positioned precisely where temperature monitoring is needed, while the control body can be mounted in a convenient location.
