Would this work?

I currently run 24vdc AB relays for lights and my temp if possible could I replace my controls with just the reef keeper head unit to activate my relays? Then would you sell just the head unit if it was 24vdc output?

Saltybob,

The Remote Display by itself cannot drive a 24V relay. All the drive circuitry for the switching is in the Power Controller and it isn't for 24V relays. They arn't even traditional relays at all, they are triacs and only switch AC power (if you care). Anyway, good question but sorry I can't say yes.
