Planning and Installation manual VV600/VV602Plus 21
The VM610P, floor mounting box is mounted in the same way as the VM602P.
5.5.2. The VM603P weather protection box
To protect the sensor from vandalism or high humidity, use a VM603P protection
box. In an environment with high humidity and large variations in temperature it is
recommended to mount a heat resistor (a few Watt is sufficient, 12 VAC/
100 Ohm/2 W gives approx. 1,5 W) in the mounting box and drill a small drain hole
in the lowest point of the box. This will give a far better result then trying to seal the
box with silicone, which will only result in condensation problems.
