Johnson Controls, the global leader for smart, healthy and sustainable buildings, 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 an easy-to-configure 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 were recently discontinued. C550A control modules feature a guided setup that allows users to easily configure the device to match the System 350 control module being replaced. 

“We’ve designed the new C550A control modules to retain the popular legacy System 350 qualities, while facilitating ease of replacement with a guided setup,” said Keith Gifford, senior global product manager, Johnson Controls. “All System 550 control modules include the option to connect to Johnson Controls System Cloud platform, which is a significant benefit, especially when there’s high risk associated with equipment downtime.”

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. Backed by Johnson Controls service expertise, when an issue is detected, cloud-based connectivity can automatically notify a technician via email or text to help expedite service and maximize uptime. This capability is amplified by Johnson Controls field leadership, anchored by a global network of service technicians with deep technical knowledge in building systems.

A full-character, LCD display screen enhances ease-of-use and offers customized sensor and output naming to simplify maintenance and serviceability. 

System 550 modules are not backwards compatible with System 350 modules. All System 350 modules must be replaced with the required System 550 module. By transitioning to new C550A control modules, OEMs can increase sensing outputs, including A2L refrigerant leak detection, using fewer modules than legacy systems have typically allowed. This can result in cost reductions and space savings within equipment designs. The C550A supports hundreds of applications, with the most popular being heating and/or cooling control, staged boiler or chiller control, boiler and chiller loop water temperature rest control, humidification and dehumidification control and combination temperature and humidity control.
