I have been using Honeywell Evohome for the 3rd year now and it works like a charm. Although, I am trying to minimize my WiFi devises at home (most of my networking is cabled at home), and I was wondering how safe/healthy HR92's are. My main problem is that one of the HR92's is about 1-1.5 meters away from my 3 year old son, so I was wondering whether I should do something about it. In the technical manual of HR92 it states : "Radio communication SRD (868.0 ... 870.0 MHz)
RX Class 2 -R ange: typically 30 m within residential buildings". I tried to contact Honeywell directly about this and the reply i got was an email reply:
"When the evoohme system is not used for a longer period of time ( during summer/vacation) there is no need to make any changes other than changing the temperature/schedule accordingly (turning the heating off, lowering the temperature, etc). If you take the batteries out or uninstall the HR92 it will lead to a lost of communication between the evohoem controller and the device and the binding might need to be redone once the system is to be used again. With the heating turned off, the controller would only communicate from time to time with the rest of the devices in the system to make sure they are still connected, and after some time it would go into a standby mode so the level of radiation would automatically decrease. We do not recommend turning the controller off or any of the other devices since that you reset the whole configuration of the system and you would not have any control over the hot water."
Then I asked "do you happen to have any official indication of the radiation levels the HR92/BDR91/Evohome Touch controller emit in winter (when fully functional) and while the system is on standby (during summer)"
and received the the below response:
" The radio frequency (not radiation) regulations are in the data sheet of each device (I attached the one for the HR92).The current regulation are the RED 2014/53/EU This is a Receiver Category 2 ISM(686.0-870.0MHz) Devices that work in this frequency band must not transmit more than 1% of the time."
I am also attaching an extract of the sheet Honeywell provided.
My question is whether HR 92 might impose any health risks (radiation) provided that its powered with 2 AA batteries? Anyone in this forum that could enlighten us in this subject?
