Model T1900 Slimline Platinum residential thermostat has a built-in humidity module, which allows the thermostat to not only automatically control temperature but humidity as well. It is compatible with dual-fuel systems and equipped with reheat for dehumidification demands. Features include Energy Watch, which tracks heating and cooling runtime hours, and Energy Save, which intelligently recalculates the start time of the morning period, depending on environmental factors, to reach the programmed set point quickly and efficiently. The thermostat is equipped with a drain pan alert, enabling the thermostat to shut down the cooling system in the event of a leak. It is programmable for seven days per week, with up to four time periods per day, and has an auto changeover, three-stage heat/two-stage cool feature, and can be used with gas/electric, heat pump, electric, and hydronic heat systems. It is compatible with the manufacturer’s line of wired and wireless remote temperature sensors. A large, easy-to-read backlit display shows the temperature in both Fahrenheit and Celsius. An LED indicator glows green or red to indicate cooling or heating for an at-a-glance view. The thermostat offers a programmable output for control of outdoor lighting systems, attic fans, and auxiliary devices.
