Information for the installer – Control box
Assembly / Connection of rain sensors
Operation
The rain sensor records both moisture on the sensor surface and decreases in outside temperature to
below +1 °C or -20 °C. Its sensitivity can be set electronically. The measured precipitation is transformed
into electrical digital signals. These are evaluated by the control system, which triggers the corre-
sponding control commands. The sensor surface is heated for faster drying. This significantly reduces
the time until the “rain end” message and, if necessary, the sunshading devices can be re-extended
immediately.
Rain 1
°C, article-no. 010830
If the outside temperature lies between approx. +1 °C and +30 °C and rain is detected, the sensor
surface will be heated to aid drying. In the case of higher temperatures or frost, there will be no heating.
If the temperatures are below +1 °C, frost will be recorded and the connected systems will be retracted
or closed and manual operation will be blocked.
Rain sensor -20
°C, article-no. 010825
If the outside temperature lies between approx. +1 °C and +30 °C and rain is detected, the sensor
surface will be heated to aid drying. In the case of higher temperatures, there will be no heating; if the
outside temperature is between approx. -20 °C and approx. +1 °C, the sensor surface will be heated
continuously. The connected systems will remain operational even in the case of temperatures down to
-20 °C (if no rain).
Assembly of rain 1 °C or rain sensor -20 °C
The rain sensor can be easily installed onto the aluminium mounting bracket article-no. 01100510 using
the angled mounting bracket supplied. Use clips, cable ties or similar fasteners to attach the measuring
cable securely to the mounting bracket so that the cable cannot be damaged by flapping and fraying
during high winds.
Choice of assembly location
The rain sensor should be mounted using the supplied bracket such that the surface of the sensor is
directed towards the weather side. It should be angled at around 15 degrees so that large water droplets
run off quickly and the sensor’s rain signal is quickly reset following a shower.
Maintenance / Cleaning
If the device is subject to extreme weather conditions, it may only be assembled at angle of around
15 degrees, otherwise water could penetrate the device over a long period of time and impair its
function. If the device is installed properly, it will work maintenance-free. If the rain sensor becomes
excessively soiled, it can be cleaned with standard household cleaning products as long as they do not
contain any aggressive or abrasive ingredients.
Cable lengths
The signal cable can be extended up to 100 m with a cross section of 0.8 mm
