Could turning on and off of the Chiller by the computer cause any problem at the chiller itself? I am using a TECO TR20 with the temp setting calibrated to match the temp reading from GHL and the setting 1C less so whenever it switches on the plug the chiller would kick in within a few seconds.

I don't know it - better you ask TECO this question

I asked a similar question of D&D, I have a Deltec Dc-750 Cooler

Message response below, that I'd like to share:-
Paul
I do not run my own cooler through my computer but David Saxby does.
If you power off and power on the cooler I do not know what the long term effect of this would be to the controller however David does it anyway.

You need to set the cooler to a lower temperature - say 25C and the computer at 25.5C so that it will always come on. Do not set the on/off temperature difference to less than 0.5C or the cooler will be switching off and on too often and that will definitely shorten the life.

I hope this helps

I used to have a Hailea chiller that lasted all of a week... so I bought a Teco instead.

I bought the Hailea because I saw it could be modified to use an external probe.

Unforntuatly the Teco TC10 I have isnt very accurate and I have recently requested the wiring diagram, but am too busy to look at it, please let me know if you have any luck.

Also noteworthy is the fact that simply turning it on and off at the switch may be ineffective, this is due to the fact these units work like fridges, it takes time to charge up and become cold, probably using far more energy than usual (these arent cheap to run). I am sure I hear the compressor running even when the chiller is not required...
