The HL***2 series digital temperature controller is a microprocessor-based controller with digital LCD display. The controller are used to control room temperature in industrial, commercial and residential environment via controlling electric modulating valve or damper with ***0Vdc (***0mA) signal or floating control. Features: Digital display of sensing temperature and user selected temperature setting on demand Proportional plus integral (PI) advanced control with analog signal output **5Vdc, **5 Vdc, ***0Vdc or ***0Vdc signal and floating output Direct / reverse acting output Output limited for over load protection Energy saving mode-external energy savings (ESI) from card key or occupancy sensors Adjustable unoccupied setpoint for heating and cooling mode control Sleep mode control Model available for build-in or remote sensor (RS) function Remote control (RC) output for interlocking on / off control application Non-volatile memory (EEPROM) retains user settings during power loss Large LCD display with blue backlight °F or °C display unit Adjustable maximum and minimum setpoint limits Adjustable deadband (some dual outputs model) Control off output when system switch at??OFF??position RS***5 network interface Modbus RTU protocol
