Johnson Controls A70HA-14 Temperature Control Overview
The Johnson Controls A70HA-14 is a heavy-duty temperature control designed for demanding refrigeration and heating applications. Built to handle a wide voltage range of 120–240 VAC, this single-pole, single-throw (SPST) controller delivers reliable open-low operation with a built-in lockout and manual reset function — providing an essential layer of protection against runaway temperature conditions. The reverse-acting auxiliary contact adds versatility for alarm or secondary control circuit integration.
Key Features
- Wide voltage compatibility: 120–240 VAC for flexible installation across commercial and industrial systems
- Single-pole, open-low (SPOL) switching action for refrigeration and heating control
- 20-foot capillary length for remote sensing in hard-to-reach locations
- 1/2″ conduit opening for standard conduit wiring connections
- Lockout with manual reset — requires intentional operator intervention after a limit trip, enhancing safety
- Reverse-acting auxiliary contact for alarm, indicator, or secondary circuit control
- Suitable for refrigeration and heating applications
Application
The A70HA-14 is engineered for use in commercial refrigeration systems, walk-in coolers and freezers, heating equipment, and process temperature control where a safety lockout is required. The manual reset feature ensures that the system cannot automatically restart after a temperature fault, protecting equipment and product from damage caused by undetected failures. The 20-foot capillary allows the sensing bulb to be positioned precisely at the point of measurement, even when the control must be mounted remotely.
