- The HL8102 series digital temperature controller is a microprocessor-based controller with digital LCD display. It is used to control room temperature in industrial, commercial and residential environment via controlling electric modulating valve or damper with 0-10Vdc (4-20mA) signal or floating control
Application
- Temperature control for variable air volume (VAV) box
- Temperature control for VAV with reheat box
- Modulating/floating valve
- Modulating/floating damper
- Constant temperature control
Specifications
- Digital display of sensing temperature and user selected temperature setting on demand
- Proportional plus integral (PI) advanced control with analog signal output
- 0-5 Vdc, 1-5 Vdc, 0-10Vdc or 2-10 Vdc signal and floating output
- Direct/reverse acting output
- Output limited for overload protection
- Energy-saving mode - external energy savings input (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 intelocking on/off control application
- Non-volatile memory (EEPROM) retains user settings during power loss
- °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-485 network interface
- Modbus RTU protocol
Mounting
