Modbus fan coil thermostat
NRFC 413, 422...424
How energy efficiency is improved
Precise comfort control in individual rooms through precise temperature detection.
Features
-
Single-room controller for heating and cooling by means of air conditioning units in commercial and residential buildings
-
For 2- or 4-pipe fan coil units, two-stage heating systems or water-bearing heat pumps
-
Can be integrated into building management systems via Modbus/RTU
-
Large configurable display with backlight
-
Integrated on/off timer
-
Deactivatable button operation for public installations
-
Valve control via 2-point or 0…10 V output
-
Supports 3-speed fans or fans with EC motor
-
Summer/winter changeover in 2-pipe applications
-
Automatic deactivation of internal temperature sensor when using a cable temperature sensor
-
Installation via mounting plate without opening the controller
-
Universal design and low installation height of 14 mm for inconspicuous fitting
