Description
The Johnson Controls P100AP-352 is a precision-engineered encapsulated pressure control designed specifically for condenser fan cycling applications in commercial and residential HVAC systems. Its direct-mount, open-construction design simplifies installation while delivering reliable, repeatable pressure-based switching performance.
Key Features
- Encapsulated pressure control with open construction for easy field inspection
- Direct-mount design eliminates the need for remote sensing tubing
- SPST (Single-Pole, Single-Throw) switching action — opens on pressure drop
- Automatic reset restores operation once system pressure returns to normal
- Engineered specifically for condenser fan cycling duty
Electrical Specifications
- Contact Configuration: SPST
- Contact Action: Open on Pressure Drop
- Contact Voltage Rating: 120/240 Vac
Pressure Specifications

Application
The P100AP-352 is ideally suited for condenser fan cycling control in air-cooled condensing units. By opening the fan circuit at low refrigerant head pressure (110 PSIG) and re-engaging the fan once pressure recovers to 170 PSIG, this control helps maintain optimal condensing pressure during cold ambient conditions — protecting compressor operation and improving system efficiency. Its 120/240 Vac dual-voltage contact rating provides broad compatibility with a wide range of commercial and light-industrial HVAC equipment.

- Trusted Johnson Controls quality and engineering
- Plug-and-play direct-mount installation saves labor time
- Automatic reset minimizes service calls and downtime
- Precise pressure differential (60 PSIG) ensures stable fan cycling without short-cycling
- Open construction allows visual inspection without disassembly
