How to DIY CHiller Fan

[David5077]

hi all,

I wanted to DIY an additional chiller fan that only operates when the chiller kicks in.

Anyone know how to do it?

Thanks!

buy external thermostat. connect chiller n fan power pt to that.

if not u can ask derrick to hook it up for u.

is it expensive ? i'm thinking of doing that as well.

But will it damage the chiller , keep turning on/off?

mm sounds easy with a recommended tech to fix it. less than $100?

I been running my chiller when external thermostat since i started to kniw about this product few years back. No issue for all my chiller. I used it for my resun, pacific cool, hailei and currently 1hp aircon compressor. If u have basic wiring skill, u can get the thermostat at sim lim.

nice.. simlim... i see what i can do over the weekend. thanks!

So the temperature of the chiller must set higher, to ensure that it will run in whatever condition ?

[angmoh]

Sorry I think is to set lower

[David5077]

i think the concept is the external thermoset replace the chiller's temp setting.

[angmoh]

David5077 yeh, so we have to either deactivate the chiller thermostat or set the thermostat temperature to lower, so that the chiller will kick-in when the power is on.

If i remember correctly, it is the 2nd shop on the left at the basement. Tell the boss u are using for fish tank so he will get the correct thermostat for u. Mine is fox 2001. If u are kiasu like me, buy a contactor also. This will prevent the chiller high load from burning the thermostat. I had a bad exp when i connect the thermostat directly to my 1/2hp chiller. It burnt my thermostat 2 mths later, sending my temp to 33 degree. I lost all my corals, a lineatus and flame wrasse. Expensive lesson learnt.

I plan do connect an extra fan to my chiller so that it run when the chiller kick start. Electronics stuff and wiring will be nightmare for me. You have derrick contact?? Maybe I try contacting him to see if he help to do modification...
