Johnson Controls S350CC-1 Module

The Johnson Controls S350CC-1 Module is a professional-grade temperature slave stage module designed to expand the multi-stage capabilities of your System 350? setup. This unit integrates seamlessly with an A350 temperature control, utilizing a 5 Vdc reference and a 24-volt power supply provided directly through the master controller?s plug-together connectors. Built for rigorous refrigeration and HVAC control applications, it features an adjustable setpoint range of -30 to 130?F (-34 to 54?C), allowing for precise sequencing and independent stage management. The SPDT relay output is rated for 10 amps non-inductive, providing reliable switching for heating or cooling loads. A clear LED output indication allows for immediate field verification of relay status, while the jumper-selectable mode ensures straightforward configuration between heating and cooling operations. Housed in a durable NEMA 1 enclosure, this module maintains high accuracy in environments with up to 95% non-condensing humidity, making it a staple for commercial chiller and furnace installations.

• Modular Scalability: Easily add multiple stages to a single A350 controller using the convenient plug-together wiring system, reducing installation time and field wiring complexity.
• Independent Setpoints: Features a dedicated potentiometer allowing for a specific setpoint adjustment that is entirely independent of the main control module.
• Flexible Application: Operates efficiently in both cooling and heating modes via simple internal jumper selection, suitable for high-impact industrial environments.
• Rugged Reliability: Enclosed in a high-impact plastic NEMA 1 case, ensuring the electronic components are protected during standard mechanical room operations.

Can the S350CC-1 operate as a standalone temperature controller?
No, this unit is a slave stage module and must be connected to an A350 series master control to receive power and sensor input.

How do I change the module from heating to cooling mode?
The mode of operation is determined by the internal jumper position. Move the jumper to the horizontal position for cooling or the vertical position for heating before powering the system.

What type of sensor is compatible with this module?
The S350CC-1 shares the A99B temperature sensor input from the master A350 controller, eliminating the need for redundant sensors in multi-stage applications.
