Hello , iam french sorry for my english. If i want to use the dt4r like your video with 2 hr92 in the bathroom i dont need to pairing the dtr4 with my boiler exact?

Thanks for the demo. Maybe helpfull to show as well that if there was a previous binding how to clear this. I had to use clr before it would bind again to a zone. The manual is not so easy to follow. But there are some QR codes to find extra info

I have checked with Resideo and this is a production issue where they are testing the thermostats in the factory but not clearing them, so they are effectively coming out 'bound' and you are having to clear them using 'CLr' first. The procedure we have shown is correct and once Resideo have rectified the issues will work fine.

Hi, I have mine set up and working but does not show when it's demanding heat. Also is there a way to adjust the tempreture it thinks the room is as its out be 3 degrees. Thank you.

It shows the setpoint when you press the up or down button but nothing else no? All the DT4R’s I have tested here are all 100% correct temperature? Maybe contact support - 0300 1301299?

Hi, Helpful video thanks. If you have a system with more than 12 zones I understand you can link a second evohome controller for and additional 12 zones. Do you know how this looks in the app? Does it come up with all 24 zones together or is it in different areas in the app etc? Thanks

@MWPHS 2 ай бұрын

In the TCC app, the second controller shows as a different location which is a 2 button swap over from one set of 12 zones to another (its quite simple).

Hi, thanks for the helpful video. What would be the reason to use a HR92 in this setup (instead of a second HR91 which is cheaper than the 92 I believe), while the room temp can be seen and set using the DT4R?

@MWPHS 2 ай бұрын

No reason. Just showing both HR91 and HR92 can be controlled in this way.

Is it possible to add the DT4R to an existing zone without having to rebind the TRVs? If a rebind is necessary can it be done without deleting the device/zone?

Yes you can do this. Give tech support a call and they can help you with this - 0300 130 1299 option 3.

What a great demo video! Do you know if the wired version, the DT4 thermostat, can also be linked the same way to the evohome? btw, which is the morel of the other thermostat which appears behind the HR91 , is it wired or wireless?

@MWPHS 2 ай бұрын

The evohome system can only control wireless Honeywell thermostats (so only the DT4R).

Thanks for the video. I have a zoned Evohome system connected to a combi boiler via an R8810A opentherm relay. Evotouch is running as the temperature sensor in the living room, a Y87RF as a temperature sensor in the master bedroom and elsewhere it's HR92s. I would like to replace the Evotouch as the sensor in the living room with a standalone temperature sensor for better accuracy/comfort and I wanted to confirm if the DT4R linked above is the correct sensor for my requirements? Many thanks.

I’m thinking of moving to an intergas boiler and will run it as open therm but it will be a heat only boiler. Wondering if the opentherm is smart enough to distinguish if it needs heating (

@jimmyc38 3 ай бұрын

That’s my setup with an Ideal Vogue S15, I can independently control DHW temps and heating temps separately. I have HW at 55°C and Heating at 40°C. I have UFH so it works fantastic with low temps.

@MWPHS 2 ай бұрын

There are a few ways to do hot water with an Intergas boiler, but my favourite is Priority Domestic Hot Water or PDHW for short. Honeywell evohome can do PDHW on any OpenTherm boiler when installed and setup correctly. Thus would mean one temperature for space heating (which can easily be under 55°C) and a higher flow temperature for hot water (say 70°C). Google search Intergas PDHW and you should find more information. 👍🏻

Is it possible to set up a room with two radiators with only 1 hr92 as actutor and sensor, and 1 hr91 as actuator for the other radiator? Thanks for your answer

@markjoseph4646 Жыл бұрын

Hi, do the TRVs monitor the temperature of the room or the water passing through the radiator?

@theheatingconsultant Жыл бұрын

When the HR91 or HR92 is bound as an actuator, it simply controls the flow of water into the radiator. They can be bound as the sensor and then they control the flow of water and act as a room sensor.

@MWPHS Жыл бұрын

The smart TRV's detect air temperature.

@sderooy 4 ай бұрын

I have an issue with this setup. Because both radiators are quite enclosed the demanded temperature is reached much earlier close to the radiator instead of the sensor in the room, and the controllers on the radiators are being closed automatically when they reach the requested temp. How can this be fixed?

@MWPHS 3 ай бұрын

Just setup an external sensor using a DT4R and evohome would use this as a temp sensor instead of the sensor on the HR91/HR92.

@@MWPHS well, I now use the round wireless sensor from honeywell (T87RF2025). But it seems the sensor in the HR91 is overruling the round wireless sensor

@@sderooy The TRV temperature sensors are a bit of a gimmick. You usually need a separate wireless (expensive) thermostat in the same room.

Can the room stat be locked in the same way that the trv head can?

@MWPHS Жыл бұрын

You can temperature limit the range of the temperature sensor (DT4R) bound to an evohome zone, but you cannot lock it from adjustment like you can with HR91's or HR92's.

Hi what does this do that Tado doesn't? (Other than Honeywell being twice the price?) I assume you won't respond if you are selling this product.

@MWPHS 2 ай бұрын

Maybe ask another question like why we don’t sell Tado? 😂 There is plenty of evohome information out there that you can simply Google, but from my perspective this is the only heating control system that can genuinely control a whole heating system using Class VIII modulation control logic.
