The key can be operated with a sharp object (paper clip, tip of a pen, etc. ) (single short pressing of the key). 3.

This status is then recognised by the fact that on the left-hand side of the display neither the symbol nor the number in the channel display is flashing. In such a case, the operation is activated by pressing one of the 3 keys. The corresponding symbol then flashes in the field to be operated ( or `CH' with corresponding number). humidity directly and also receives the measurements of up to a maximum of 5 IROX radio sensors. In the two ) the temperature currently measured is displayed in °C (or °F) and the information windows (radio sensors CH1. . . . 5 and relative Humidty in %. The following operations can be made in this function: 5. 2. 1 Reading of the temperature and the rel. humidity from each channel Activate the CHANNEL key briefly to jump from channel to channel. The next channel is displayed with each press of the button and activated for other operations. The sequence of the activation is --> CH1 ---> CH2 --> CH3 --> CH4 --> CH5 --> --> CH1 --> etc This is independent of whether a radio sensor is available in the system or not. Note: The measurement is always depicted in the lower window; the channels 1-5 one after the other in the middle window. 5. 2. 2 MIN/MAX memory a) With the `MEMORY' key you can read the Max/Min memory of the active channel by pressing it briefly (flashing symbol or CH1 . . . .

The setting on the display appliance or the sensor is to be made independent of one another and only affects the display of the corresponding device. 5. 2. 4 Temperature and humidity alarm The alarm function is programmed individually per channel ( / CH1. . . . Each alarm is defined by an upper and lower limit of the temperature and/or the rel. If one of them is exceeded or undercut, an acoustic and optical alarm is triggered. Important general information about the thermo/hygro alarm: - An alarm programmed on Channel 1 can only be triggered by the sensor 1.
