Announcement: Flow Temperature Optimization now available for V generations and tado° X (OpenTherm)
Hello community,
We are pleased to announce the release of a new Flow Temperature Optimization feature for tado° customers with V2, V3, V3+, and X devices directly connected to a boiler or heat source.
Flow Temperature Optimization at a glance
With Flow Temperature Optimization, you can avoid overheating your central boiler or other heat source. This is done by setting a maximum flow temperature that ensures your flow temperature is high enough to heat your home, but not so hot as to overwork your boiler or heat source unecessarily.
A typical maximum flow temperature for a boiler is about 50°C - 60°C. Homes with underfloor heating may only require 35°C - 45°C for optimal efficiency. If you have already set a maximum flow temperature directly on your heat source, tado° will never exceed that maximum. Even if you set a higher maximum flow temperature in the app, tado° will not override the maximum that you set manually.
🚨 OpenTherm required 🚨
You can use Flow Temperature Optimization if:
- Your heat source supports and uses OpenTherm
- Your heat source is connected to tado° via a Wireless Receiver or at least one Wired Smart Thermostat
The feature can be controlled via the tado° app by going to Settings > Flow Temperature Optimization
Automated Optimization
With Auto-Assist, users can access an advanced setting within Flow Temperature Optimization called Automated optimization, which adjusts your maximum flow temperature based on the current weather conditions in your area.
Automated optimization won’t affect the room temperature you set in your home, yet the energy savings can be significant.
To find out more about Flow Temperature Optimization, you can access our dedicated articles in the tado° X Help Center and the V Help Center.

Brilliant, nice to have spotted this earlier. Feels like it could be on by default. I also feel that being able to enable a Tile to show the flow temperature on the home screen for this feature would be really nice to have..

You can always make a feature request 😊0 -
Is this strictly Opentherm or does it also work with EMS on Worcester Bosch boilers?0
-
Does it not work with an expansion unit using opentherm?

Hi unfortunately only max is able to be set. For my Vitodens 100 elwhen one flame is running sometimes even two flames I guess temp is too low so boiler is only circularing with pump with no actual heating0

Great feature, thanks for adding.
Is it possible to see what the automatic option has set the max temp to over time, maybe on a graph?
Thanks1 -
@Rob is there any plan to enable it for EMS etc in the future or will it remain opentherm only?0

I don't think so. For Opentherm, the thermostat overrules the boiler flow temp setting. So, it makes sense to enable thermostat users easy access to the feature. Easier than the professional app (+tado support) which could set this setting before.
For EMS, the thermostat does not overrule the boiler flow temp setting, so unlike for Opentherm there is no hard demand for tado to set this setting. Additionally, our professional app and support cannot change this setting for EMS either, as far as I know.

@Rob Fair enough, thanks for the reply. Unless I'm misunderstanding though what difference does it make than Opentherm can override the boiler setting? The guidance surely would just be to set your boiler flow temp manually to a high temperature, such that Tado could work out the rest.
I am definitely of the belief that there is demand for this feature when using EMS - After writing my original comment I found this pre-existing feature request for it https://community.tado.com/en-gb/discussion/18672/ebus-max-flow-temperature-setting-like-the-one-just-released-for-opentherm#latest

Well I've got a Viessmann Vitodens 100-W (Set to OpenTherm with Tado V3+) and I've just switched this on as I had the email today.
I'm not really clear on exactly how it works but it says its more efficient so I'll give it a go.The Viessmann app is now showing (The flow temp was showing 70 before I enabled the bit in the Tado app):
I set the Tado app to:

I already have a boiler that sense the out side temperature and adjusts the temperature of water going to my radiators. Would this feature still be of use to me?0
