I am having a problem with my RK2 multi-timer feature on channel 5. I have it set up as an auto topoff running a pump for 1 minute at 6AM and 1 minute at 6PM. Problem is that the LED on channel 5 goes out after 1 minute but the circuit is still energized and continues to run the pump. Last time it happened it dumped 5 gallons of RO water into the sump before I manually pulled the plug to shut the pump down.

I am switching channel 4 and 5 as hopefully a temporary fix for now.

Any else having this problem?

reftalker,

If the light turned off then the Power Controller should be turning it off as well. Definitely use channel 4 (or 8) as you suggest, that is why those hard relays are there, for devices that don’t “like” to be turned off by solid state switches.

Give me an update after you try that.

Thanks for the response Nick. I will let you know after a few tests tonight.

Switching the pump to channel 4 has solved the problem I was having. The pump has turned off every single time since my last post. The only other problem I am seeing now is the first time setting on the multi-timer is not working. I have it set to come on for 1 minute at 6AM, but nothing happens, no light on the RKII, pump doesn't turn on. The 2nd and 3rd timers work fine. I first noticed this on channel 5, but it seems as though channel 8 has the same problem.

Any ideas?

Good, about channel 4. Not sure about the timer question. Let me try a couple things and get back to you.
