The theromostat display is large and the backlight is bright. The temperature accuracy is poor. The temperature is off by as much as three degrees at night, then slowly gets accurate to within one degree during the daytime. This drifting on and off temperature by three degrees is continuous and a real pain for level operation.

Large display with bright back light

Temperature accuracy and precision very poor
