chiller on controller

[lilrobb]

So, a little dilemma just dawned on me.

My chiller has always been run with its own separate controller, mainly because I never had a spare plug on my controlled outlets, haha
Now that I have a few to spare - should I run the chiller off of the controller? I am worried that switching the chiller completely on and off might not be the best thing for it.

Any input?

that is how I do mine, but I am new to any of it. Did you get my PM?

I don't think it should be a problem. The only reason I could think of would have to do with the temp sensor/probe receiving power but you should be able to supply it with it's own power source if it's needed.

Oh, and the LCD if it has it maybe N/1 or normally closed.

Mines independent robb...fwiw

Let it run on its own controller and have it plugged into a port on the reefkeeper so if for some reason it sticks on the power can be cut. Just a thought for an extra safety.

That sounds like a good idea... maybe set the Apex to kill it at something like .2 F higher than the chiller's own controller is set.

FWIW, I've been running my chiller off a PC4 on my RKL for two summers now, and no issues.

I assume this isn't THE chiller, it's 220v, right?

I have had a 1/4hp chiller fry the small relay on my DC-8 from to much power on startup, so just make sure the socket can handle the power.

set it up so that the on and off temperatures are governed by the chiller itself, then set up your Apex/DA controller so that IT acts as the "failsafe" for the system..

for instance:
DA/APEX will come on at 82.5* and go off at 77.5*
chiller/controller will come on at 83* and go off at 78*

set your lights to turn off at 83.5*


that way you'll be using both temperature probes independently (probably located in different parts of the system) to monitor the temperature..
