Yet another question about Flow & Return settings....

[jchasty]

I have a British Gas 330+ Condensing Boiler.

Quick question on operating the above, if I may?

I've looked at the manual - it really doesn't answer my question....

There is an LCD display and an Up / Down toggle switch.

I can set the CH flow temp up and down using the toggle switch and having read up on condensing boilers, I understand that this should be around 75C?

Obviously, the display shows the temp going up & down in line with the switch - stay with me here.....

When I let go of the switch, another number (between 50 & 56C) is displayed permanently on the screen.

The exam question is: What does this denote? Is it the temperature of the returning flow?

Thank you!

The exam question is: What does this denote? Is it the temperature of the returning flow?

On most boilers that would usually be the temperature of the flow leaving the boiler.

Yes, thank you! I've managed to confirm that through the diagnostic menu. So, I have an issue then....despite setting the flow to 75C, the display never gets past 50C....
