Specifications on this page are taken from the Prolon Heatpump Controller datasheet, REV 7.3.0 / PL-DATA-C1050HP-C/F-EN.
The PL-C1050-HP controls air-to-air and water-to-air heat pumps, with the mode selected in configuration rather than by part number. PI control loops manage compressor and auxiliary heat staging.
It handles up to two compressor stages plus up to two auxiliary heating stages, with economizer, preheating and emergency auxiliary heat sequences built in. All four inputs are configurable, so the same terminals can be assigned to outside, return, supply or water intake temperature, night setback, proof of fan or alarm.
On a Prolon network the HP acts as the master controller and supports FlexiZone weighted-demand grouping across the zones below it.
Best For
- Air-to-air and water-to-air heat pump units and systems
- Up to 2 compressor stages with up to 2 auxiliary heating stages
- Multi-zone networks where the heat pump acts as master over Prolon zone controllers
Key Features
Air-to-air or water-to-air
Works in Air-To-Air mode or Water-To-Air mode, selected in configuration.
Modbus RTU or BACnet MS/TP
Communication is Modbus RTU (RS485) or BACnet MS/TP (RS485), up to 127 nodes.
Two compressor stages plus auxiliary heat
Controls up to 2 compressor stages with up to 2 auxiliary heating stages.
Four configurable inputs
4 configurable inputs with selectable functions: outside temp, return temp, supply temp, water intake temp, night setback, proof of fan or alarm.
FlexiZone weighted demand
Manages multiple zones by evaluating the average weighted demand of the zones using customized groups.
Economizer and emergency heat
Sequence set includes economizer, preheating and emergency auxiliary heating.
