Johnson Controls A27AA-9250X Electronic Temp Control Module [Refurbished]

The Johnson Controls A27AA-9250X is a module from the A27 modular electronic temperature control system. Rather than a single self-contained thermostat, the A27 range is a family of plug-together modules - one-stage and two-stage thermostats, differential and frost protection thermostats, S27A stage modules, D27A display modules and Y27L signal converters - assembled to suit the plant being controlled.

The modules are electronic rather than mechanical, using a remote sensor instead of a liquid-filled bulb, and are designed for DIN rail or panel mounting inside a control cabinet.
