The Prolon PL-C1050-VAV-PI is the pressure independent version of the C1050 zone controller, supplied with the air flow sensor so the zone can control to an airflow setpoint rather than damper position.

Specifications on this page are taken from the Prolon Zone Controller datasheet, REV 7.3.0 / PL-DATA-C1050VAV-C/F-EN, and the Prolon VAV Zone Controller Hardware Guide, REV 7.3.2 / PL-HRDW-VAV-C1050-C/F-EN.

The PL-C1050-VAV-PI is the C1050 zone controller supplied with the air flow sensor, which is ordered separately on the base PL-C1050-VAV. With the sensor in place the zone controls to an airflow setpoint, so zone delivery holds as duct static changes elsewhere in the system.

Everything else matches the base zone controller: outboard floating or modulating actuators, four triac outputs, one 0-10 VDC analog output, and configurable sequences for radiant floor and duct heater.

The network port is configurable for Modbus RTU or BACnet MS/TP over RS485, with a second RS485 port for a digital room sensor or computer interface.

Best For

  • Variable air volume zones controlled to an airflow setpoint
  • Zoning using outboard floating or modulating damper actuators
  • Zones with a radiant floor or duct heater sequence

Key Features

Pressure independent control

Supplied with the air flow sensor that is ordered separately on the base PL-C1050-VAV, so the zone controls to an airflow setpoint.

Flow sensor 0-2 inch WC (0-500 Pa)

The installed sensor reads 0-2 inch WC (0-500 Pa), roughly 0-3500 ft/min depending on the flow cross used.

Identical control platform to the base VAV

Same four triac outputs, 0-10 VDC analog output, dual RS485 ports and sequence set as the PL-C1050-VAV.

Modbus RTU or BACnet MS/TP

The network port is configurable for Modbus RTU (RS485) or BACnet MS/TP (RS485), up to 127 nodes, with a second RS485 port for a digital sensor or computer interface.

Outboard floating or modulating actuators

Designed to use single or multiple outboard damper actuators, floating or modulating.

Configure from the wall sensor

Monitoring and configuration can be done from a digital room sensor, as well as locally or remotely in Prolon Focus.

Frequently Asked Questions

What is the difference between the PL-C1050-VAV and the PL-C1050-VAV-PI?
The VAV-PI is the pressure independent version, supplied with the air flow sensor that is ordered separately on the base VAV. Control, outputs and communication are otherwise identical.
What is the flow sensor range?
0-2 inch WC (0-500 Pa). Depending on the flow cross used, that works out to roughly 0-3500 ft/min.
Does it support BACnet?
Yes. 1x Modbus RTU (RS485) or BACnet MS/TP (RS485), up to 127 nodes, plus 1 RS485 port for a digital sensor or computer interface. BACnet MS/TP is enabled by moving switch 8 of the addressing dipswitch to ON; no extra communication card is required.
Does it include a damper actuator?
No. It is designed to use single or multiple outboard damper actuators, floating or modulating. The actuator is ordered separately.
What is the analog output range?
0-10 VDC, 40 mA max, with resettable fuse. The output signal is configurable for 0-10 VDC, 2-10 VDC or 0-5 VDC.
