This main controller is the center of the guest room control system. Equipped with a 24MHz eight-digit CPU with a 32KB RAM capacity, the high-tech device offers ample control terms. The guest room controller separates strong and weak current wires and avoids the interference of signals. The main board adopts the SMT productive technology and foreign relay. The controller has been tested under high temperature, moisture and high load to ensure the product can work well in an adverse environment.
