Could not be simpler.

Easier than ever. My UT 200 had given up the ghost. Since this probably happens more often within 1-2 years, I've been looking for an alternative. Important was a moisture resistance, as in our garden shed are often more than 80% humidity. The device can only be set to a temperature not like the UT200 to a temperature range. The display is always lit red and displays the current temperature, a small red LED also displays if just is unlocked power.
