Specifications from the Prolon Zone Controller (PL-VC2000) datasheet REV 7.3.0 (PL-DATA-VC2000-C/F-EN) and the VAV Zone Controller VC2000 Series Hardware Guide REV 7.3.2 (PL-HRDW-VC2000-EN), reviewed September 19, 2026.
The Prolon VC2000 series zone controllers are designed for variable air volume zoning systems. The built-in microprocessor offers precise digital control to maximize performance. The outputs and control sequences are all fully configurable, either locally or remotely, using free software or from the digital room sensor. The on-board brushless actuator provides electronic feedback on damper position. When in a network, the VC2000s can share information such as the occupancy state, the demand, the supply temperature and more.
Best For
- Pressure independent VAV zones that must hold a CFM setpoint, not just a damper position
- VAV boxes or zone dampers with a 6-20 mm (0.25-0.75 in) damper shaft and at least 37 mm (1.5 in) of usable spindle
- Zones that add reheat: the triac output drives a duct heater or radiant floor sequence
- Modbus RTU or BACnet MS/TP integration into an existing building network

Frequently Asked Questions
Does the Prolon PL-VC2000-PI support BACnet?
Yes. The PL-VC2000-PI has one RS485 network port that runs either Modbus RTU or BACnet MS/TP, with up to 127 nodes on the network. A second RS485 port is reserved for a digital sensor or a computer interface.
Does the PL-VC2000-PI include the airflow sensor?
Yes. The PL-VC2000-PI ships with the pressure independent airflow sensor installed, reading 0-2 inch WC (0-500 Pa), so the controller regulates to an airflow setpoint rather than damper position alone.
How much torque does the integrated actuator produce?
45 in-lb. The actuator is a Belimo unit using Halomo technology and mounts to damper shafts 6-20 mm (0.25-0.75 in) in diameter with at least 37 mm (1.5 in) of usable spindle length, matching the Belimo LM mounting range.
What outputs does the PL-VC2000-PI provide?
One digital output and one analog output, both protected by resettable fuses. The digital output is a triac rated 10-30 VAC dry contact, 300 mA max, configurable ON/OFF or pulsed for heating or cooling. The analog output is 40 mA max with a configurable signal of 0-10 VDC, 2-10 VDC or 0-5 VDC, and runs modulating, ON/OFF or pulsed for heating or cooling.
What power supply does the PL-VC2000-PI need?
24 VAC ±10%, 50/60 Hz, Class 2. Typical consumption is 3 VA and maximum consumption is 5 VA. When one transformer powers several PL-VC2000-PI controllers, allow 5 VA per controller.
What can the analog input monitor?
The general purpose analog input accepts 0-5 V, 4-20 mA or thermistor signals and can monitor discharge air, occupancy, CO2 levels and more. Zone temperature comes in separately over the RS485 digital sensor port.
Can the PL-VC2000-PI run standalone?
Yes. It runs standalone or networked up to 127 nodes. Outputs and control sequences are configured locally from a digital room sensor or remotely with the free Prolon Focus software.
