General
The HL2023 series thermostats are stand-alone microprocessor based thermostats with LCD display. The thermostats are designed to on/off control
the fans, valves, dampers or electric heaters in fan coil units and heating applications.
Models are available for heating/cooling/ventilating control of 2-pipe or 4-pipe fan coil units.
The fan speed can be manually controlled by the fan speed control push button.
It is wired to run high/medium/low speed continuously or to automatically change the fan speed.
The thermostats provide RS-485 communicating interface and MODBUS protocol for system integration. The thermostats can be controlled by local
manually, master controller or operating by the BAS.
