INTENDED AREA OF USE
MULTIFUNCTIONAL
ROOM CONTROLLER
e RMFPX-2R are multifunctional room controllers featuring
adjustable temperature, relative humidity and CO2 setpoints. ey
have a wide range of low voltage power supply. e control algorithm
controls one single analog / modulating output based on the measured
T, rH and CO2 values. All parameters are accessible via Modbus RTU.
Code Supply Connection
RMFPG-2R 18—34 VDC / 15—24 VAC ±10 % 3-wire
RMFPF-2R 18—34 VDC 4-wire
