FS20-Funkschaltsystem

Hi
(Again sorry for using english)
I have a problem with the above mentioned two dewices that the range is very short. I made everything work and then placed them about 5 meters from each other and then they didn't work anymore. It's an ordinary old house from 1924 so it's just brickwalls, but of course som pipes and electric installations - also I have a burglar alarm using same radio 868 mhz - but it works, and in much longer distance.

Any ideas ?

Thanks in advance

Hello Mr.Hoyer

In our opinion either the FS20STR-2 thermostat (transmitter) or the FS20 SU-2 receiver is defective. Please return both devices for an overhaul to your distributor.
