Hailea Chiller with External Temperature Controller without modification to the chiller and without DIY risk (Part 2)
I brought two different types of temperature controllers from the Internet, http://www.taobao.com/ .
Let me review the first type of temperature controller, it is a very simple one. I have been running it for one to 2 months since the end of May. So far, no problem and very reliable.
It have three buttons only, and you just set the kick in temperature. When the temperature is above the set temp + 1 degree C, it turns on the switch and turns on the chiller.
It have a 3 meters temperature sensor, that is long enough to put into anywhere in the tank, eg in sump or main tank.
It have an output of 2000W (about 8A output current) which means it can be used for 1HP chiller.
The best is it is about Chinese Yen 35 to 50 plus shipping cost. I paid about S$15 for it included shipping cost. Cheap or not ......
Cons:
1. There is a large temperature offset for my unit, I set to 32 degree C to get the tank temperature of 30 degree C. So two degree difference, Offset is not a problem at all. That means if I want to get tank temperature of 28 degree C, I need to set the unit to 30 degree C.
2. Another thing I find is that the temperaturen difference to turn on and turn off is only 0.5 degree C not 1 degree C. That means more kick in. :(
I have another type of temperature controller that can set the temperatures to turn on and turn off. It is much more expensive than this one. Will do a review when I have run in the controller.
Overall, I still find it useful for chiller with demage controller. It is value of money and it is reliable until now.
