1st (first AC of a group)

Screen: Room Devices (step 5 of 7) — Air conditioning card, AC groups (shown only for a room with two or more ACs).

What it is

The 1st mark on an AC in a group, or in All AC. The first AC gives the readings shown on the group's card.

What to enter

Press the grey 1st on the AC you want first. It turns gold.

What it changes

In the house: The project saves by itself. The hub does not use the groups; it gets commands for each AC.

In the app: At the next Save & Deploy, the AC screen shows All AC, then your groups, then each AC. A group's card shows the readings of its first AC. A command from a group goes to every AC in it, and any AC that does not answer is named.

If it goes wrong

• If the card shows the wrong temperature, make another AC first.
• By default All AC uses the room's first AC, and a group uses its first ticked AC.
