Specifications on this page are taken from the Prolon Standalone Heatpump Controller datasheet, REV 7.3.0 / PL-DATA-C1050HPS-C/F-EN.
The PL-C1050-HPS is the standalone version of the C1050 heat pump controller, built for unitary systems that serve one space from a single space temperature sensor.
It works in air-to-air or water-to-air mode, controls up to two compressor stages or two stages of auxiliary heating, and includes economizer, preheating and emergency auxiliary heating sequences.
All four inputs are configurable and can be assigned to outside, return, supply or water intake temperature, night setback, proof of fan or alarm. It runs stand-alone or on a Prolon network of up to 127 nodes.
Best For
- Unitary heat pump systems running from a single space temperature sensor
- Air-to-air and water-to-air units
- Up to 2 compressor stages or 2 stage auxiliary heating
Key Features
Built for single-zone unitary systems
Designed for unitary systems using a single space temperature sensor.
Air-to-air or water-to-air
Works in Air-To-Air mode or Water-To-Air mode, selected in configuration.
Two compressor or auxiliary heat stages
Controls up to 2 compressor stages or 2 stage 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.
Configurable protection limits
Built-in protection sequences with configurable temperature limits and minimum delays.
Protected outputs
All 4 digital outputs and the analog output are protected by resettable fuses.
