Old Tunze Temp Controller

[viper357]

Hi all

I have just bought myself a 2nd hand 7027/2 temperature controller. Here is a pic of it.

The guy I bought it from has never used it. It didn't come with any instructions, I have no idea how to set the HI and LO temp settings on it, although I can set the LO setting but can't seem to figure out how to set the HI one.

Google is not helping much either

Please help guys, thanks

Viper,

I'm not sure this will help, but at the Tunze website, they do have a manual for the 7028 thats downloadable in PDF, and the functions "MAY" be similar enough to help you out?

Here is a link;

I've tried that Ed, but they talk about adjusting a screw on the side, which I don't have and the 7028 has more buttons than my 7027.

Thanks for trying

Maybe I am just confusing myself here, maybe the LO setting is the desired temperature, then when the temp drops below that it will switch the heaters on until it reaches the desired LO setting, but it still confuses me why it says LO, surely it should say HI as well ?????

From what I've read on this controller... you set a temp, and it will either turn on or off the supplied power block... depending on which setting in the battery compartment you have set.

Not being the best with words... I'm trying to say, if you have it set to "HEAT" in the battery compartment, if the temp goes lower than your setpoint... it turns on power to the powerblock where hopefully you have your heater plugged into. Once temp raises above that setpoint... turns off power to powerblock. Works in reverse if you set it to "Cool" in the battery compartment, to turn on your chiller.

Yeah, I think you're right, will give it a test run and see how it goes, thanks for the help Appreciate it.

Sorry I didn't have any direct experience with this piticular Temp controller. Good thing is, this post will remain on the server, and hopefully someone that does have the 7027 will see it for you!
