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 is the zone controller in a Prolon VAV or VVT system. The actuator is outboard rather than integral, so the same controller works across damper sizes and you pick the actuator to match the box.
It works with or without a flow sensor. Without one it runs pressure dependent; with the optional sensor fitted it reads velocity pressure over a 0-2 inch WC (0-500 Pa) range. Configurable sequences for radiant floor and duct heater are included.
Two RS485 ports are provided: one for the network, configurable for Modbus RTU or BACnet MS/TP, and a second for a digital room sensor or a computer interface. Monitoring and configuration can be done from the digital sensor at the wall, without a laptop.
Best For
- Variable air volume zoning using outboard floating or modulating damper actuators
- Zones running with or without an air flow sensor
- Zones with a radiant floor or duct heater sequence
Key Features
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.
Works with or without a flow sensor
Runs with or without a flow sensor. The optional sensor reads 0-2 inch WC (0-500 Pa). For a factory-installed sensor, order the PL-C1050-VAV-PI.
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.
Radiant floor and duct heater sequences
Configurable sequences for radiant floor and duct heater are included.
FlexiZone weighted demand
FlexiZone facilitates multiple zone management by evaluating the average weighted demand of the zones using customized groups.
