480 1000 041/01 Humidity Sensor Installation Instructions
This unit can be wall or mast mounted. It should be fitted where there is free movement of air and away from heater /ventilation outlets, chimneys, warm walls and flat roofs etc. The length of the cable affects the calibration and therefore should not, if possible, be shortened or lengthened.

The cable is connected in the junction box with the white two core cable (blue and white cores) connected to the AIR TEMP terminals and the grey (Red Black and White cores) to the rain sensor and RH terminals as per the
diagram.

If another air temperature probe is being used, such as the one on the wind sensor, then there is no need to connect the temperature probe on the "Hummiter" as this probe does not have a bearing on the humidity reading and is only there if another air temperature is not already in use.
