The ESP Electronic Programmable offers “Best In Class” 22Amp Max Rating for larger heating circuits. Featuring 7 individual day programmability for maximum temperature control; four time and temperature settings. 3 wire, line powered. Large back-lit display. This thermostat took years to develop and has become a popular 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.
