IO Hvac Controls ESP-400 Control Panel R-22 While the standard 200RB isThe iO HVAC Controls ESP 400 is an advanced static pressure control module designed to modernize residential and light commercial zoning systems. This 4 zone ESP panel utilizes a proprietary algorithm and a high precision ZPA SPS static pressure sensor to maintain ideal duct pressure without the complexity of a bypass damper. By continuously monitoring the discharge air plenum, the ESP 400 detects when static pressure exceeds the user defined setpoint
