Reef Radiance DM-165e

How old is this box?
At one point in the past, the dimming booster was optional. If your box is really old, you may not even have it.
The only way to find out is to open the box and find the revision number in the board.

It is stamped 8.1.

Wait you said expansion relay box? I believe you can't control dimming on that one.. Only main relay.

[rschneider77]

I read that some where also. My ato is connected the main relay box. Can I switch them, as in ato to expansion box and dimming to main box.

[lnevo]

ATO? Thats not dimming ports...

[rimai]

8.1 is definitely new, so you are good on that box.

[rschneider77]

Inevo, you are correct. My brain was seeing main relay box and my mouth was speaking head unit.

Rimai, can the 2 - 2 pin ports on the expansion relay box be used, when the same ports on the main relay box are being used by Jebao pumps.

[rimai]

Negative.
Only the ports on the main relay box are usable.
If you need more channels, you need the dimming expansion module.

Well, I guess that will be my next purchase.
