digital electronic fan speed controller rel. humidity/time
These automatic speed controllers are fully digital and control the rotational speed of single phase (230 Vac/50 Hz) voltage controllable motors according to the RH level. They can be used to maintain a stable and constant RH level in a target area. These controllers provide a great number of user adjustable options.
rh2s controllers provide auto and manual operation modes, possibility for input/output adjusting, kickstart with programmable time duration, min and max speed limitations, off level with adjustable hysteresis, digital readout, TK protection, internal real-time clock (day/week programmable), outputs for valve (230 Vac), slave/power units (0-10V/ 0-20mA) and an RS485 interface.
Auto mode in function of RH: speed rises when RH increases
Manual mode speed rises/decreases on user demand untill the next switching point set by the clock,
automatic return to auto mode
Extra input remote on/off, to max. speed
Adjustable settings min safety speed, min speed, max speed,2 setpoints, proportional range, kickstart, mode
change, hysteresis, off-level, TK delayed detection, time to max speed
Motor protection by connecting thermal (overheating) contacts of the motor, option for delayed detection
Analog output selectable between proportional and digital (for alarm function on TK input)
RS485 interface for connecting remote sensor or to have BMS compatibility
