Self Learning Setback on Demand Thermostat SDHW1001

Self Learning Setback on Demand Thermostat


The Columbus Electric model SDHW1001 setback on demand thermostat is a self learning 7 day setback thermostat designed specifically for commercial and industrial applications. Unlike most setback thermostats this thermostat doesn't require programming. With the use of a motion sensor, it learns your schedule, and changes automatically with schedule changes. Regardless of your schedule, it automatically returns to economy after you leave. The Auto Comfort feature recovers to the comfort mode before you arrive. The holiday feature automatically sets back the temperature to the economy setting on any day that no-one shows up. This one model will work on single and multistage equipment up to 4 stages of heat, 4 stages of cool, or any combination of heat and cool up to 4 stages. Also compatible with 2 stage heat, 1 stage cool heatpumps.
