HL8102 PID Temperature Controller to control modulating or floating valves

Product Description

●The HL***2 series digital temperature controller is a microprocessor-based controller with digital  LCD display.
●The controller is used to control room temperature in industrial, commercial and residential environment via controlling electric modulating valve / damper with ***0Vdc (***0mA) signal or floating control.
●The controller provided proportional plus integral (PI) control with modulating and floating control output.
