- Baxi trainer Richard takes a closer look at the IFOS (In Flue Outdoor Sensor) system boiler kit, for the Baxi 600/800 System boiler ranges.
The Baxi IFOS provides an easy and cost effective way to comply with the requirements of Boiler Plus when combined with a timer and temperature control. Saving energy and reducing carbon emissions, the IFOS can also provide additional SAP benefits for new build developments.

I know it's been a year but I've only just seen this video as I'm considering having Weather Compensation fitted.
The instructions for my 824 boiler clearly state in several places that "The 230V switched signal for external controls (frost thermostat - room thermostat - timer) must always be taken from terminal 2 at the boiler".
I assume this is to ensure that if either of the 5A Fast Blow fuses go, there is no 230V feed back to the boiler PCB, which there would be if terminal 2 was fed from the SFU.
Unless there is some other reason, this video therefore doesn't show the boiler connected correctly according to Manufacturers Instructions. I'm not a Gas engineer, but I can read a book and a circuit diagram, and I'm in dispute with an Electrician over it as I think he ought to come back and correct it.
Hi Tony, thanks for your message. I have just spoken to our training manager and here's what he said - You're absolutely right, the fuses are there to protect from the 230V supply. However, the weather compensation connections are low voltage and therefore do not come through the 230V supply.
The point I'm making is that you have a wire in terminal 1 but not in terminal 2. So it was wired up incorrectly before the IFOS was fitted according to the Manufacturers Instructions I have, which is a bit concerning considering you are a Baxi training centre. Also, the System Boiler IFOS kit has a relay PCB *does* connect to 230V as it requires "A 230V switched live from the DHW cylinder thermostat ..."
Fit them as standard, or I'm not using them
?? I didn’t understand at first.
But you mean Baxi should fit them seen as sold ... Day1??
Or you won’t fit them? Is that correct? Sorry... I don’t mean any disrespect, if it comes across.
How can they fit them as standard the majority of systems won't have the extra wire at the old existing boiler to start with?
