The weather station consists of an outdoor unit with integrated wind, rain, light, temperature & GPS sensor and an evaluation unit with power supply in a 2-TE housing. The outdoor unit is mounted either on the roof (mast) or on the wall (south side) and connected to the evaluation unit with a 4-pin low voltage cable. The evaluation unit establishes the connection to the LCN bus via the I connection of a customer-provided LCN-SHS, -SH, -HU, -LD or -UPP, -UPS from serial number 150101 (from Jan 2012). Thanks to the GPS receiver, LCN-WIH transmits the precise time and date to the LCN bus. The evaluation unit supports all time zones worldwide and the local summer/winter time changes in all countries of the world. The wind sensor works without moving parts: A measuring resistor is heated electrically. The passing wind cools the resistor. The wind speed is calculated from the temperature loss and written into the T variable. The LCN-WIH is a complete weather station for controlling all weather-dependent systems and functional processes in a building. The parameters for the corresponding functions are set in the included LCN bus modules.
