digital electronic fan speed controller temperature/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 temperature. TE2S controllers can be used in ventilation and in heating applications and provide a great number of user adjustable options. All data is visualized on a liquid-crystal display (LCD), presented by user friendly and intuitive multilingual menus. The parameters can be set through four-button keypad (supplied with a lock function). There are user and installer priorities set by passwords. The standard temperature range is from -25 to 65 °C.
TE2S controllers provide auto and manual operation modes, possibility for calibration and input adjusting, additional remote control input (heat/cool - day/night switching), kickstart with programmable time duration, min and max speed limitations, off level with adjustable hysteresis, digital readout, TK protection, internal real-time clock with two level switching (day/night, day/week programmable), outputs for valve (230 Vac), slave/power units (0-10V/ 0-20mA) and an RS485 interface.
Auto mode COOL: in function of temperature; speed increases when temperature rise / HEAT: in function of temperature; speed decreases when temperature rise
Manual mode speed rises/decreases on user demand untill the next switching point set by the clock
Adjustable settings min safety speed, min speed, max speed, off level, 2 set points, hysteresis, proportional range,
kickstart, calibration parameters, mode change , TK delayed detection, time to maximum speed
Input for remote control remote heat/cool switching, remote on/off switching, max. ventilation
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)
