Hi Richard. I fitted one of these with a vaillant heat pump recently and I piped it up A to rads and B to cylinder, I wired it the opposite way around to what you suggested. It seems to work fine but is there any downside to doing one way or the other?

Hi, we have a dying CM927 (up button for temperature no longer works) and it is paired to a BDR91 receiver. (Gas boiler). Can we just buy a wireless thermostat - either Pro or T3R wireless and pair it to the existing receiver? Thanks

Hi, do I need to use the relay? I have a building with 8 rooms and each room has 2/3 zones and I’d like each room to be able to set their own temperatures, as the TRVs currently installed are inaccessible behind rad covers. So ideally each room would have a controller, sensor in each room and HR92s on each rad.. Do I need the relay for this, I’m not sure the WiFi would reach the boiler room. Hope this makes sense.
@MWPHSАй бұрын
Normally you would use the relay to control the heat source, otherwise the heat source would have to run 24/7 ready for when there was a demand.

Hi, I do hope that you can help. I have just watched how to remove a Honeywell clicky thermostat and the video was 100% accurate. It shows/I have red, yellow and blue wires powering it . The rest of the house setup is exactly as you show … I have the Honeywell timer for hot water/heating. Can I fit the thermostat you suggest and is so what are the wiring positions? Thanks in advance.
@MWPHS2 ай бұрын
The DT4 can replace any existing non-programmable thermostat. Unfortunately, I can only comment about the thermostat we used in the video (which is also the equivalent to a Honeywell T6360 clicky stat). The wires that are in wiring terminals 1 & 3 on the existing thermostat, are the live and switched live wires. You use these wire (and these wires only) in the DT4 switching terminals, the rest of the wires are made safe as I've shown. If you need any technical support with the DT4 product, please contact Resideo on 0300 130 1299. Thanks for watching the video.

That's a BDR91 thermostat! Not like the one that your sister company MWPHS sent me!! Now, after sending it back, you refused to refund me claiming it was damaged!! My engineer only tried to connect to the Honeywell thermostats and didn't install it on the wall! Even Honeywell didn't recognise the model of the receiver you sent me when we called them to try to fix the issue. The worst is that I'm sure Waseem believed his own lies!! Your company shouldn't be ashamed!!
@MWPHS4 ай бұрын
The BDR91 is manufactured in many different shapes under many different product codes, so they won't always look like the one in this video. Essentially they all do have the same PCB, so do work exactly the same as in this video. If you have a look at the video we did 9 months ago (kzbin.info/www/bejne/ql6pmYKtfLxqhdksi=xBGuYJCwbxrz4bQO), both the BDR91 and the DT2 wireless relay box (which is essentially a BDR91 with a different plastic fascia) are fully compatible with all Ramses 2 Honeywell thermostats. The DT2 wireless relay box supplied on MWPHS (mwphs.co.uk/product/wireless-relay-box-bdr91-replacement-replaces-all-pre-2021-honeywell-bdr91/) is fully compatible with all Ramses 2 thermostats? What was the problem you had maybe I can look into this for you? Thanks, Richard.
@alexojus4 ай бұрын
@@MWPHS Hi Richard, sorry if I can't call, but as mentioned to Waseem, I can only send emails when I'm at work. I ordered two BDR91, one from Amazon and one from you. Both are to connect with a DT4 thermostat. The one I bought from Amazon connected straight away to my DT4, the one I ordered from you didn't connect. We didn't install it, no screws, nothing. We did nothing to that receiver apart from trying to connect to the thermostat. I didn't check the receiver when I received it but I only noticed that it was in a bubble wrap rather than in its box like the one I received from Amazon. Waseem said that the box had been destroyed in transit... It's only when my engineer came to install everything that he noticed the difference between the two receivers. You claim that they are the same, they are not or yours is faulty...Waseem or your company keep saying you sent the right receiver but you didn't and that the receiver was damaged or in used condition. If it was damaged, ( I saw the pictures and unless, you look for it, you wouldn't noticed), it wasn't by us! I paid for a delivery postage, a return postage and a receiver that it's either the wrong one or is not working and you're refusing for a refund. As I said, next time, I'll go to Amazon, much easier and they don't blame the customer for things they haven't done.

@@alexojus I had replied to you before realising you had left our business two 1 star reviews on Google and a negative Trustpilot review? I have physically seen the wireless relay box you returned with my own eyes and I don’t think I have seen many items returned to us in such poor condition? It is completely unsaleable. It is now not about the money, it’s about the fact we are being call liars and scammers when we have refused to refund an item that has been returned in unsaleable condition. We are not Amazon, we are a small family owned heating supplier who has been running for 10 years. Some of our items are bought direct from the manufacturer as an OEM replacement. All the wireless relay boxes we supply are checked/picked to order by our warehouseman (who is called Nick, been with us 7 years and religiously checks all items before dispatch) and they are packed in electrostatic packaging to protect them from physical and electromagnetic damage. This is not bubble wrap. If you want the detail on the bags we use they are here ( www.kitepackaging.co.uk/scp/bags-for-electronics/open-top-antistatic-bag/ ). When I get into work tomorrow I will get the DT4R I use for my KZbin videos and test the wireless relay box you have sent back for operation, however the reason you have given for return was that it wasn’t a BDR91. So is the reason for return that the item is faulty? If that is the case that wasn’t clear from the returns paperwork or discussion I had with Waseem?
