SL808 wireless controller of temperature and humidity of fan-coil
Abstract:
SL808 controller which widely apply in industrial¡¢commercial and familial
field. The results which compare temperature and humidity in room with setted
temperature and humidity by controller can control terminal unit of the fan-coil of
air condition and humiditiy and electric control valves,and user may adjust
temperature and humidity by controller. As a result of energy saving,the controller
which includes key-lock function and other practical functions is very fit for
installing in the public area.
Product features:
􀂾 Aesthetic appearance £º It has six touched keys and a large LCD with colored
backlight.
􀂾 Powerful functions£º
It has some modes such as cooling,heating,aeration,humidification and
dehumidification.
It can extend some new functions for exchanging new wind,electric heating,water
pumps,and so on.
It can selecte a running function between manual operation and automatic
operation,also selecte speed of wind among high,middle,low under cooling mode
or heating mode.
It can operate low temperature protection,lock key-presses,convert temperature
display mode between Fahrenheit and centigrade.
􀂾 safe and reliable£ºIt consists of high anti-jamming MCU£¬relays which is safe and
reliable as output control devices.
