model. All the features you want without too many buttons. Simple

is always better. We have added backlighting to the full-size display

and an on/off switch to control the illumination. On the front two

simple buttons control the temperature up and down, while all the

programming keys are hidden under the front cover, protected

from wandering, unauthorized ﬁngers. Comfort and convenience is

always our primary goal at King.
