A3 series temperature controller -RPT
A3 Series Temperature Controller - RPT: Equipped with refrigerant pressure detection, featuring a simple and exquisite design, it supports more installation environments. With an external dimension of 32x74x78mm, it is suitable for use as a micro temperature controller in medium and low-temperature refrigeration systems. It has two output channels: one for the compressor and one for defrosting (either electric heating or hot gas). Additionally, it has two NTC probe inputs: one for the storage temperature and one for the evaporator temperature.
The USB port allows users to insert a programming key (HOT KEY) for uploading or downloading the parameter table.
