Drayton Wiser heating app question
Discussion
Morning all,
I've fitted a Drayton Wiser room stat with smart TRV's on the radiators, all working ok.
What I don't understand is the relationship in the app settings between overall temperature (on the "main" wireless stat) compared to the individual temp settings on the radiator smart TRV's.
If all radiator TRV'S are set to 20 degrees and are up to temp, if I set one TRV to 21 degrees the boiler fires up and the central heating pump runs until that room reaches 21 degrees, all good.
If all TRV's are set to 20 degrees and I set the main "house" wireless stat to 22 degrees, should that overide the TRV settings (20 degrees) so that the radiators can pump out more heat, otherwise surely it would be impossible to raise the "home" stat temperature reading past the lower TRV setting?
Conversely, the main "home" wireless stat is currently set at 19 degrees but indicating an actual temp of 14 degrees, yet the heating doesn't come on. That doesn't sound right? The only way I get the heating on is to set the radiator TRV's temp above the indicated room temp that the TRV "sees".
I'm probably doing something stupid but I don't know what!
Any help much appreciated! :-)

My understanding is that the ‘wall’ thermostat should not and does not override the radiator thermostats.
You may know this already but the room where your ‘wall’ thermostat is should not have radiators with smart thermostats fitted
No, I didn't know it shouldn't be positioned in a room with rads with smart TRV's!You may know this already but the room where your ‘wall’ thermostat is should not have radiators with smart thermostats fitted
If it doesn't overide the radiator TRV's, I don't get what it's purpose is. If you set the temp of the "wall" thermostat higher than the temp settings on the smart TRV's then it sounds like nothing will happen. Surely it's pointless?
With "dumb" system if you want the house temp raised you just turn the wall stat up a degree or two , the boiler fires up and the rads kick out heat until the stat reaches its set to then switches the boiler off.
I must be being thick but I don't get the point of the main stat with this Wiser smart system?
Thanks for all the replies gents
I replaced all radiators in the house before adding wiser smart TRV's to ALL of them with the exception of the "wild" rad in a bathroom.
Currently I am setting the temperature of the house by adjusting each room smart TRV up or down. Some rooms (that aren't being used) have the temp of the smart TRV set to 14 so they are effectively "off" all the time. It just seems a bit of a faff having to keep adjusting (via the Wiser app) each room radiator smart TRV.
I am not using the wireless Wiser thermostat at all

Back to the OPs question... it's not clear if you've "told" the hub that the thermostat exists. Link it to a room or house area without Wiser TRVs and it will act just like an old standard wired themostat:
- when it measures the temperature as below the set temp it will call for heat and the boiler will run until that room is heated to the set temp
- the rooms with Wiser TRVs should not be affected - they can still call for heat independent of that thermostat
- however, a TRV's call for heat takes precedence over a thermostat. so if by setting a TRV to 20 degrees and a thermostat in a non-TRV area to 14 degrees that area may get to over 14 degrees before the TRV gets to 20
I'm not sure how I "tell" the hub that the thermostat exists. When I look in the Wiser app on my phone or tablet, I can see the thermostat which its current temp set point and actual temp it's detecting. Do I need to do something else?- when it measures the temperature as below the set temp it will call for heat and the boiler will run until that room is heated to the set temp
- the rooms with Wiser TRVs should not be affected - they can still call for heat independent of that thermostat

Go into Settings,
Select Devices,
Select “Room Thermostats”
Select Location
Pick which room you have it in (it will then control that rooms Wiser TRV’s)

Just had a look, my thermostat is currently "unallocated". It looks as if I can only allocate it to one smart TRV so effectively one room. Does this mean the thermostat can only control one TRV, or can you allocate multiple TRV'S /rooms to it? I don't seem to be able to add more than one. If this is the case, then I think my expectations were wrong as I thought I could just turn the thermostat up if I wanted ALL radiators to come on?
Many thanks for posting those instructions, I wish my kit came with an idiot guide!

You can set individual schedules for each room; have you done that?
No I'm a luddite with this sort of stuff. I'm literally opening the app each time I want to turn the temp up/down on a radiator and manually making the adjustment.
Is there some sort of online idiot guide anywhere, something that treats you like a child in explaining how this fking thing works?

I don't mean to sound like a d*ck but it's not clear why you've bought the system if technology isn't your thing.
A thermostat needs to be linked to a room; you can't just have it "floating".
Through the app you can "boost all" to heat each room for x degrees for y minutes or you can create "moments" to control multiple devices such as all bedrooms or the kitchen and the lounge or whatever combination you chose. Look under automation.
Have you watched Drayton Wiser's video on youtube?

I bought the system for a (larger) house I've moved into. Other half works from home most of the time, so I thought a "smart" heating system would save on energy bills as it's much easier to control individual room heating rather than heating the whole house when just the "office" room is being used. I do like the new setup, being able to adjust individual room temps from a phone or tablet is super convenient. I suppose the thermostat issue derives from the fact I'm only used to "dumb" heating systems where you turn the temp up and all the rads come on until the set point is reached.
I did work out the "boost" function (only took me about a month ). I will look at the automation section like you suggested. I will also watch the vids you linked.
Many thanks
