We're then going to go to commissioning and you'll notice that these are greyed out and a lot of installers have got to this point and realised they can't do any test runs or air purges.

And this is because the operation of the unit is probably on.

So if we go back out of here, back to our operation menu, into here and make sure both of these are off.

Once they're off we can go back to our menu, back down to commissioning, go into commissioning and you can see now they've lit up so we can actually operate these systems.

We've got the operation test run, actuator test runs and the air purge.

The air purge is really great for commissioning to get rid of all that air that's in that system.

So we're going to make sure all our automatic air vents are open and we can start an air purge.

Click into air purge and it's going to ask you what type of air purge you would like.

You can do a manual air purge or you can do an automatic air purge.

The automatic air purge will turn the mid position valve over and backwards.

It will modulate the pump and move all the air around the system that it can.

If you put it in manual mode it will ask you how fast you want that pump to run.

So you can run that pump at 100%. So we set it to a manual for this one.

We can set what circuit we want so we can air purge our tank, we can air purge our space heating and then we're going to tell it what pump speed we want.

We can go on a high pump speed to get that air out of our system.

Start air purge, okay and it comes up with a menu and it will show us our flow rates, our water pressures and what circuit it's actually air purging at that time.
