Programmable Thermostat

The Resideo HONTH1100DH1004 PRO 1000 Series is a non-programmable digital thermostat engineered for single-stage heating applications in residential and light commercial settings. This horizontal wall-mount unit delivers precise temperature control within +/-1 Degrees F accuracy, making it ideal for maintaining consistent comfort in spaces heated by gas, oil, electric, or hydronic systems, as well as millivolt systems up to 750mV. Designed for straightforward operation, the thermostat features a backlit LCD display and intuitive slide-switch controls that require no programming or complex setup. The unit operates in standard mode with a temperature range of 40 Degrees F to 90 Degrees F, with an optional garage mode extending the low-end to 35 Degrees F, accommodating seasonal variations and diverse facility requirements. Power flexibility is a key advantage of this model. The thermostat accepts 24VAC power supply or operates independently on AA alkaline batteries, providing reliable performance even in applications where hardwired power installation is impractical or unavailable. This dual-power capability ensures uninterrupted temperature management across various commercial and residential HVAC installations. The compact horizontal form factor measures approximately 3 15/16 inches in height by 2 7/8 inches in width, fitting seamlessly into standard wall spaces without requiring extensive modifications. Construction quality meets Honeywell/Resideo standards for durability and long-term dependability in demanding environments. The PRO 1000 Series thermostat is the practical choice for facilities requiring straightforward, reliable heat control without advanced programming features. It suits retrofit applications, maintenance operations, and budget-conscious installations where simplicity and accuracy are essential.
