The XW70LH dimension is 38x185mm, it is a microcomputer control for medium temperature or low temperature forced air cooling system device. It has five relay outputs to control compressor, evaporator fan, electric defrost or reverse cycle (hot gas defrost) and lighting. The last relay output can be used for auxiliary output or alarm signal. It provides built-in real-time The clock RTC can be used for up to 6 defrost cycles per day, and can also be divided into two situations: holidays and working days. Work. A "day and night" function with two different setting values ​​can be adapted to different times of day and night. Energy saving operation. It also provides four NTC or PTC probe inputs, the first for temperature control and the second for temperature control. circuit placed on the evaporator to control the defrost termination temperature and manage the evaporator fan, one of the two digital inputs can be used as a third temperature probe. The fourth temperature probe can be used as condensation temperature or display temperature alarm signal. The HOT KEY output of the programming key allows connection to the device, which can be converted to an external communication converter XJ485-CX ModBUS-RTU protocol can be connected to the X-WEB series monitoring system network of dIXEL monitoring system. The controller program can also be programmed from the keyboard using the HOT KEY. The controller provides a fully functional configurable parameter table setting that can be easily programmed by the user via keyboard buttons program operation.
