Thermostat Problem

[Chewy56]

Hi, First post and would be very grateful for any help.

I have a Honeywell DT92E Thermostat that is only intermittently communicating with the wireless relay box BDR91.

There is a full green light on the BDR91 and if I switch the Potterton programmer on HW and CH the radiators come on and switch off when it it reaches the temperature on the DT92E after that any communication stops. The BDR91 is in a very inaccessible place. Is there any way I can sort the problem out on the DT92?. I have seen a video showing how to rebind the two but I don't think I will be able to get to it!

Sounds like the BDR91 was installed in the wrong place to begin with, if rebinding operations need to be done... it should be where it can be accessed.

I dont know the devices, but could it just be needing new batterys in the thermostat?

What about interference.... does it work if the thermostat is moved to another place?..... or something near the relay blocking the signal?

Many thanks for your reply. I replaced the batteries when this started. I have also tried moving the thermostat without success. The DT92e now shows the temperature clearly but there is no sign of any wireless signals. Does that mean the DT92E is faulty? I am not sure how it communicates with the relay. Does it use wi-fi?

It is wireless communication but not wifi.

Just googled it '!

Just googled it 'There are many short-range wireless technologies used in connecting today's devices to establish local area networks. Bluetooth, WiFi, and Zigbee are three common standards used for wireless local area network (WLAN) connectivity.'

and all can be affected by local inference.

Any big lumps of metal in the vicinity of the reciever? such as water tanks or boilers?

Thick stone walls between transmitter and reciever?

I have had the DT92E for a couple of years and this is the first time this has happened. The receiver is in the loft above the room.
