My chiller comes on every 5 minutes for 1 min 30 sec. I read on another forum just change the flowrate and chiller will rest for 1 hour, so I lowered the Eheim output to minimum, and once the chiller kicks off, the temperature falls lower than what I set and the heater comes on instead so it seems to be worse off this way.
I've tried pressing +2 or -2 with the CA LED displayed, but I don't understand what I'm doing and the thermometer on the glass still reads 27 degrees while the chiller reads 25.
I don't have an instruction manual. Can anyone please help out?
Thanks.
Warm regards,

Baton courtesy.....service with a smile!
GaspingGurami, I have use a Resun before but that was a long time ago. It was my 1st chiller. But sadly, I can't help you now as I have forgotten what the setting are. Even my present chiller, a Sfiligoi chiller for my shrimp tank has not been disturbed after being setup around 2 years ago. I had tried to manipulate some of the setting but I can't figure out what they are. My chiller is set at 25 degrees for the time it has been in operation until now. Sorry for not being able to assist you.
If you've learnt, teach, if you have, give.
Don't walk behind me as I might not lead, don't walk in front of me as I might not follow. Walk beside me, as my friend.

Appreciate your response, BFG.
I now switched the Eheim pump to a higher output. Now the chiller runs for a longer period: 2min 30sec, then stops for 4 minutes before coming back on again. But this time, the inbuilt heater didn't come on, and the thermometer on the tank registers a lowered temperature (26deg) that tallies with the temperature reading on the chiller.
Now that I know it is working, can anyone teach me how to set it up such that it will not kick in so often only to run for so short a duration? I worry that all these frequent start-stop will prematurely wear out the machine.

First of all, it is not unusual that the temp. readings on the chiller and the readings from the thermometer differ. This is because the reading on the chiller is the temp. of the water going into the tank! The reading from the thermometer is the temp of water in the tank! Therefore after the chiller kicked in, just before it stopped, you can get the temp you set, if not close!
After it stopped, it will allow the water in the tank to rise about a degree or so before coming on to chill the water again. This should explain the difference in readings on the chiller and thermometer!
Secondly, how big is your tank?
Cos if your tank is small, the water capacity is also small! The ablity of your water retaining the coolness is greatly reduce with the volume. Therefore your water drop and rise in temp. rapidly!
This should explain why your chiller kick in so often
GaspingGurami,
The CAL thing of Resun Chiller is to sync the chiller display temperature with your tank temperature. Play with + or - vlaue so that tank temperature by a themometer show the same as the one display by the chiller.
Now you have to decide which is accurate? If your themometer on glass is accurate, you may one to adjust the CAL value so that your chiller display actual temperature of tank water.
Adjusting the CAL vlaue will not help if your chiller is under power to drive the tank. You can adjust the temperature setting a degree up, that could make quite a bit of compressor run freqence.

Thanks for your replies. My tank small volume, no wonder it kicks in often. Now why didn't I think of that instead of getting caught up with the "technical clutter"

Hi,
I am owning 1 HP chiller for the 6' tank.
My experience is,
a) always get a chiller 1 size up at least which can support your current tank. This is to ensure your investment is protected when your upgrade your tank or increase your lighting. Also, low HP chiller actually will drag logger and waste electricity in order to chill the desire temp.
b) I replaced my chiller internal thermostat with another thermostat (Korea Fox brand bought in Sim Lim Tower basement) in which the temp sensor is placed inside my tank. With this, the chiller will not kick in as often , and the temp on the thermostat will reflect the actual tank temp .
c) I like this FOx thermostat , reasons are :
- sensor can put inside the tank
- can set temp at desire temp with extra 1 decimal digit
- set the offset temp if higher than the desire temp.
Ie desire temp 26, offset +/- 0.5. Chiller to start when it reach 26.5, and chiller will stop will it reach 25.5
- can delay the chiller starting if reach the offset , ie delay 10mins when it reaches 26.5
- it can be calibrated also if the sensor is off compare tank thermometer.
Cheers
Wow, bro Neon!
Can share how much you pay for your 1 HP chiller?
Wat brand is it?
How much does it cost to replace the thermostat?
Thanks!
I bought 2nd hand around $900 over. It is hailea , which is actually AquaMedic full parts but made in China. I used to own a 1/2 HP Hailea also, and it was equally good to chill my 6' but drag much longer as expected.
Around $80How much does it cost to replace the thermostat?
Neon bro!
Thanks!
Did you install it by your own?
What Has Ended Marks A New Begining
Yes, but do it at your own risk. Although I am not electronic or electrical trained, but I still manage to figure out .Did you install it by your own?
There is not much difference when I compare my Hailea thermostat with the Fox brand. There always be 2 wires for power input and one of the live wire split out to another port. There is one port for the temp sensor. I can not use the internal temp sensor with this fox brand as it is not compatible. Anyway, it suits my purpose to control base on my tank temp.
Cheers
Hmm...but does the Fox brand work for resun chillers?
What Has Ended Marks A New Begining
I wan to automate my tank!
Hi Neon,
When you use the fox controller, how do u connect ur chiller to the controller? Do you have to open up the chiller to bypass its internal sensor?
Thanks

Put it this way :
a) something to control the power on and off for the compressor to chill the passing water.
b) using a thermostat :
* you can make your settings to your liking
* there is a series of ports for wiring , there will be some for power input DC source , some for power output to the compressor
* when it reaches the desire setting, the thermostat will pass thru the current like a on/off switch to the compressor
* there is 1-2 port for the temp sensor
To have a simple illustration, if one want to chill your tank water using fans , one would :
a) may get a thermostat , and hook up the power input source onto the ports
b) hook up the fans cables on the power output ports
c) hook up the temp sensor on the port(s) and drop the sensor into the tank
When temp rises in the tank, the thermostat will kick in the power and start the fan. When it reaches the temp according to your settings, it will cut off of the power output to fan.
Cheers
Yes, any one or any device which take 220 v.Hmm...but does the Fox brand work for resun chillers?
Cheers
