FCR013 - Communicative room temperature controller for heating and cooling panels and VAV damper

Description

FCR013 is a communicative controller of heating and cooling panels and a VAV (variable air volume) damper. It measures temperature in the room air using a room unit and it may either work autonomously, or be connected to a primary controller (MiniPLC or SoftPLC) or SCADA (RcWare Vision or any other SCADA able to act as Modbus master). As a room unit, UC013 is used.
