What is room number n

[lutinfr]

Hi IES,

I'm searching for a way that can control air flow but depends on temperature of other room, kind of double skin facade,

In help for formula, I see:

ta ta(n) Return value of variable ta for room number n
tdr tdr(n) Return value of variable tdr for room number n
tr tr(n) Return value of variable tr for room number n
rh rh(n) Return value of variable rh for room number n
g g(n) Return value of variable g for room number n
co2 co2(n) Return value of variable co2 for room number n
sol sol(n) Return value of variable sol for room number n
e1 e1(n) Return value of variable e1 for room number n


I use Room ID for n, but it doesn't works, can you give more detail on room number n and how do I identify this number for each room.

Thank you.

Within ModelIT when you click on a room, a number is displayed near the bottom of the screen to the left of the room name (the Room ID is on the right). These are the numbers that are referenced within the formula I think.

One word of warning is that the numbers within ModelIT start on zero but the numbers seen by apache might actually start at 1. In that case, n would actually be [ModelIT Number] + 1. You'll have to experiment a little to see which is correct I think.

Additionally, I think these numbers can change if you reorder the room list or change geometries.

Oh yeah, thank you, our double skin works very well with n.
