Atag One Controller or similar?

To test the sensor - heat it with hair dryer - with the heating set to 25 degrees - the flow temperature should fall significantly.

The room influence setting should have been determined and set by your installer. The setting is to adjust the impact ( positive or negative ) of the precise positioning of the external sensor against the pre programmed temperature curves in the boiler software.

What you are aiming to achieve is to maximise the duration that the boiler is condensing ( ie. return flow below 55degrees C ) Obviously that is not the case on very cold days - where the driver is to maximise the flow temperature, whilst keeping the temperature delta across the heat exchanger to around 15 degrees C - I think, unless my memory fails me.

If you cannot reengage your installer, set the influence setting to 1. Stop tinkering and leave the system to operate. Observe how it behaves, then after a few weeks make any required adjustments and repeat the process again.

Constant adjustment of the system settings is unlikely to deliver an effective result.

Try to understand over time how the complete system behaves - optimisation ( if applicable), boiler modulation and external temperature flow temp compensation

Any questions get back to me

Thank you - that's very helpful. I have done as you suggested apart from the hair dryer part as it's raining here just now. I'll monitor what goes on. So far the return flow has been in the 30 degrees area.

The installer was out again this morning just to finish off. I have spoken to him about this but he admits he's not totally sure on all of the weather compensation himself. He did offer to contact Atag and ask all the questions but I can probably do that myself if necessary.

I'll come back if I have more questions. I'll post up a screenshot of the system diagnostics too at some point.

Thank you again for your help.

It will not pair with the virgin network very easily , is difficult to set up and the app is not user friendly

Just came across this.
I recently changed my Virgin Hub 3.0 to "Modem" and added a new Netgear wireless router.
The ATAG controler absolutely refuses to find the new wifi system.
ATAG help, isn't.

I'm going to change from the ATAG controller ASAP.

I fitted a Nest and it works perfectly. Kop

Thank you.

I've asked the local guy (who also installed the system for me) to switch to a Nest.

He's trying to talk me into taking the new ATAG "Tado"?

Aside from that, ATAG have simply abandoned me. I was emailing and chatting on the phone to someone at ATAG who was trying to help me get the network configured, but he's just stopped responding. Absolutely shocking.

So, meantime, I can only set the controller manually.

I have no problems with the Boiler - it seems like a decent piece of kit and has been for the last 3 years. But the controller? Arghhh!

I can only speak from experience I'd have a nest every time.
