Johnson Controls announced the launch of new PENN System 550 C550A web-enabled control modules designed to streamline the transition from analog to digital temperature, humidity and/or pressure sensing within commercial HVAC-R equipment. System 550 C550A is a functional replacement for legacy System 350. PENN System 550 C550A control modules support one temperature, humidity or pressure sensor input and serve as functional replacements for System 350 A350 (temperature), P352 (pressure) and W351 (humidity) control modules, which was recently discontinued. C550A control modules feature a guided setup that allows users to configure the device to match the System 350 control module being replaced.

All C550 control modules (C550C and C550A series) provide two-way remote connectivity with an annual subscription to the Johnson Controls optional Controls System Cloud. On-board Wi-Fi connectivity allows authorized users to remotely monitor HVAC-R system health via the PENN Controls System Cloud.
