HL8102 Digital Temperature Controller

Descripción del producto

GENERAL The HL***0 series digital temperature controller is a microprocessor-based controller with digital LCD display. The controller provided the floating control for damper actuator to adjust air volume in pressure-dependent variable air volume (VAV) box. Models are available for floating cooling control for damper actuator to adjust air volume, and modulating control for heating device to reheat temperature. The controller provided proportional plus integral (PI) control with modulating and floating control output. FEATURES - Digital display of sensing temperature and user selected temperature setting on demand - Proportional plus integral (PI) advanced control with analog signal output - Selectable **5Vdc,**5 Vdc,***0Vdc or ***0 Vdc signal output - Selectable 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 - &#****6;C or &#****6;F 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.
