I've tried to add a system profile manually by adding the profile to the appropriate .pdb and .pro files. However when I then import these profiles from the system folder to a project, I find a slight difference.

the formula I'd like to use: controller is on if room temp is less than 20C and CO2 concentration is greater than 450ppm

manually added system profile:
PERCENT,DAY_3605,DAY HEATING
(int(ta<20) & (int(co2)>450), 00.00,
(int(ta<20) & (int(co2)>450), 24.00,

the formula as imported into a project:
PERCENT,DAY_3605,DAY HEATING,0,0,
0.01*((int(int(ta))<20) & (int(int(co2))>450)), 0.00,
0.01*((int(int(ta))<20) & (int(int(co2))>450)), 24.00,

As you can see there is an additional '0.01*' added before the formula, - any thoughts on why this might be?

Thanks

It's a fine guess! My understanding is that a modulating profile begins with 'PERCENT,' and an absolute begins with 'ABSOLUTE,'.

Both the profiles I've posted below are modulating, however the fact that there has appeared this 0.01 factor does imply some kind of automated correction. I'm lost as to why this might be.

HI,

Sorry I've been keeping an eye on this but not responded yet. Been a bit busy of late but I'll have a look at this at some point and try work out what's going on.

I don't see any problem in theory with what you have done but editing the project files is a risky business so there may be some correction the software applies that you will have to be aware of.

I'll let you know if I find anything out.
