CAN I USE THE DC8 THAT COMES WITH THE ACJR FOR THE ACIII?

Yes, you can. They are the same.

The only differences that I can think of between DC8's are that some have the reset button / breaker with a 15 on them; where as, the older ones have a 15 amp fuse to change out. Also, newer DC8's have relay controllers on plugs 4 and 8 which are designed to control low wattage devices like the Aqualifter. Other outlets on the DC8 may fail to turn an Aqualifter off correctly. This supposedly only occurrs on the DC8's, not DC4's or DC4HD's. I think Neptune Systems calls this a soft start which supposedly puts less wear and tear on devices. The triacs (soft start) are on Plugs 1-3 and 5-7. The 2 relays outlets (4 & 8) are for use with higher current devices, or pumps which have a poor power factor.


HTH!

Wrt relay ports; DC8s with S/N > 9000 have ports 4 and 8 changed to relay ports which better handle small deviced (e.g., Aqualifter pumps, C02 valves, etc).

and a minor correction:

The 2 relays outlets (4 & 8) are for use with higher current devices

Ports 4 and 8 are NOT intended for use with higher current devices. This will cause the relay contact to fuse together and the port will stop working. Devices like lights, chillers are especially bad for these ports.

Ken,

Thanks, I copied the above from one of Curt's messages. Possibly Curt was referring only to the EB8 and not the DC8.

Cajun Reefer,

Yes all direct connect boxes will work with the Apex. Apex is expandable to thousands of controlled outlets. The expandability is virtually unlimited.
The EB8 is rated for 5 Amps on outlets 1-3 & 5-7 (triacs), and 10 Amps on outlets #4 & #8. The 2 relays outlets are for use with higher current devices, or pumps which have a poor power factor.

No worries; I'm not sure what Curt was referring to.

You may recall some recent messaged where people had stuck relays and the suggestions was to smack the DC8??? Running high-power devices on the relay ports is what causes this problem and (sometimes) a good smack will unstick the relay.
