HC4201TA
LCD Thermostat (HC4201TA)
HC4201TA series of LCD thermostat with a high voltage
version (100~240VAC) and a low voltage version (12VDC). It is used for Fan-Coil control (FCU) either for two-wires or 3-wires valve control. Its large LCD screen with internal sensor monitors indoor temperature and automatically control the cooling/heating to maintain the temperature desired.
Features:
- Low profile mounting either in single-gang frame or part of
multi-gang frame (Infinit series: 2,3,4 or 5-gang frame). - Large screen LCD with good visual effect, low reflection and slim.
- touch screen operation with back light.
- Touch screen feedback with beep sound (can be muted).
- RS-485 communication port, MODBUS protocol (optional).
- Function status display on LCD screen.
- Temperature compensation (±5 ℃).
- Auto Off with timer control.
- Data retention after power failure .
- Energy saving or Eco mode.
