Cooling operation is less obvious - I think the cooler itself runs to a very coarse setting and the heater is used for fine control. In particular, I think you have to set an auxiliary control output on the temperature controller to enable the cooler. I have had this working so it's not impossible but may require a bit of fiddling. | Cooling operation is less obvious - I think the cooler itself runs to a very coarse setting and the heater is used for fine control.

I had a go at using the envirmental chamber to make sure some welding rods were free of moisture. | |||
The user interface is still a mystery to me but I pressed buttons until the top red numbers showed current temperature the lower red numbers showed "100.0" (desired temperature) and the XK1 and "hand" red LEDS were illuminated. I left the green switch with a snowflake symbol off. | |||
The temperature shut up to 50degC quite rapidly then took a couple of minutes to get to 100degC | |||
to get to 100degC. The XK1 led flashed when it was at 99.9degC. | |||
I have not worked out how to change the desired temperature. --AJP | |||
