The Prolon PL-M2000-HP is a Modbus RTU heat pump controller that runs in air-to-air or water-to-air mode, stages 2 compressors and 2 auxiliary heating stages, and acts as a FlexiZone master on a Prolon network.

Specifications sourced from Prolon datasheet PL-DATA-M2000HP-C/F-EN, REV 7.3.1. Verified September 18, 2026.

Overview

The M2000 HP controls air-to-air and water-to-air heat pump units, with the mode selected in configuration rather than in hardware. It stages up to 2 compressors and 2 auxiliary heating stages, and adds economizer, preheating, emergency auxiliary heating, and static pressure functions. On a Prolon network it acts as a master controller, and its FlexiZone system manages multiple zones by evaluating the average weighted demand of customized zone groups. All 9 analog inputs are individually configurable for thermistor, dry contact, 4-20mA, or 0-5 VDC.

Best For

  • Air-to-air or water-to-air heat pump units, selectable in configuration
  • Heat pumps with 2 compressor stages and 2 stages of auxiliary heat
  • Zoned systems where the rooftop unit acts as the FlexiZone master
  • Units that need economizer, preheat, or static pressure sequences on board

Frequently Asked Questions

Does the PL-M2000-HP work with water source heat pumps?

Yes. It is configurable to run in air-to-air mode or water-to-air mode, and the input list includes a water supply temperature point.

How many compressor stages does the PL-M2000-HP control?

Up to 2 compressor stages, plus 2 stages of auxiliary heating.

Can the PL-M2000-HP act as a network master?

Yes. It acts as a master controller when connected to a Prolon network, and its FlexiZone system manages multiple zones by evaluating the average weighted demand of the zones using customized groups.

What input signal types does the PL-M2000-HP accept?

Each of the 9 analog inputs is individually configurable for thermistor, dry contact, 4-20mA, or 0-5 VDC.

What outputs does the PL-M2000-HP provide?

5 triac digital outputs rated 10-30 VAC source, 300 mA max with a resettable fuse, plus 3 analog outputs at 0-10 VDC, 40 mA max. Each of the eight outputs has a manual/off/auto switch.
