Johnson Controls C-2220-13 Pressure Selector

The Johnson Controls C-2220-13 serves as a high-performance pneumatic pressure selector designed for complex HVAC sequences requiring logic-based signal arbitration. Functioning as a master module, this unit is engineered to receive two input signals and accurately transmit either the higher or lower pressure signal to the output, depending on your system configuration. Built for high-volume applications, the C-2220-13 features a 0-25 psig input range and delivers a precise 1-19 psig output at 25 scim. Contractors often utilize this module in multi-zone setups where pressure signal transmission must be centralized. Its modular design allows for significant scalability; you can integrate up to 19 C-2221 slave modules to manage up to 20 individual zones from a single master station. This ensures consistent pneumatic control system performance and streamlined maintenance when managing HVAC zone control logic in commercial environments.

Key Benefits for Technicians

• Scalable Architecture: Supports the addition of 19 slave modules for comprehensive 20-zone control.
• High Volume Output: Delivers 25 scim to maintain signal integrity across long pneumatic runs.
• Versatile Logic Selection: Reliable high-low pressure selection for cooling/heating changeover or damper positioning.
• Field Proven Durability: Standardized Johnson Controls pneumatic parts footprint for rapid retrofit or replacement.

Common Questions

How do I configure the C-2220-13 for high vs. low pressure selection?
The module selection logic is determined by the internal diaphragm orientation and port connections. Refer to the specific piping diagram for your sequence to ensure the master module is correctly biased for the required signal priority.

Can this master module drive multiple actuators directly?
While the 25 scim capacity is robust, exceeding the air volume requirements of the connected branch lines can cause signal lag. In large-scale deployments, utilizing the slave module expansion is recommended to maintain response times.

Is the C-2220-13 compatible with non-Johnson pneumatic systems?
Yes, as long as the system operates within the 0-25 psig input parameters and standard pneumatic signal ranges, this selector can be integrated into most legacy pneumatic HVAC controls.
