● ETS RDF870KN only
Functions
For room controllers
● Maintain PM2.5 or CO
2
level or both via controlling a fan of fresh air units or air purifiers
● Display of room temperature via built-in temperature sensor or bus
● Setpoint adjustment for PM2.5 and CO
2
only
● PM2.5 and CO
2
values are received from external sensor or via bus.
● CO
2
control has higher priority than PM2.5 control if both controls are available.

● Display outside temperature via bus or outside sensor input in °C
● Display PM2.5 via bus or outside sensor input in μg/m
3
● Display CO
2
via bus or outside sensor input in ppm
● Display VOC via bus or outside sensor input in mg/m
3
or %
