Programmable Thermostat

This 120 VAC line-voltage programmable thermostat serves as a reliable replacement for the Resideo TH115-A-120S/U and compatible models, engineered specifically for electric heating applications. Designed for hardwired installation on 50/60 Hz circuits, this unit delivers robust control for baseboard heaters, radiant ceiling systems, convectors, and fan-forced heating equipment with a maximum load capacity of 16.7 A at 2000 W resistive load. The thermostat features a backlit LCD display for clear visibility and intuitive operation, combined with an SPST epoxy-soundproof relay switch for reliable, quiet switching performance. Its 7-day programmable functionality allows facility managers to establish customized heating schedules throughout the week, optimizing energy efficiency across multiple zones or buildings. Temperature control ranges from 40 to 86 Degrees F in active operation, with an extended operating range of 32 to 140 Degrees F and ambient tolerance up to 158 Degrees F. The precision thermistor sensor maintains a 1 Degrees F differential, ensuring accurate temperature maintenance. The compact white enclosure measures 4.9 x 2.8 x 0.9 inches and mounts vertically, featuring a hidden programming button to prevent accidental adjustments. This industrial-grade replacement unit is ideal for facilities requiring dependable climate control in commercial buildings, manufacturing spaces, or multi-unit residential properties. The tinned copper leads provide superior corrosion resistance for long-term durability in demanding environments. Compatible with Honeywell Home and Resideo legacy systems, this thermostat combines proven technology with straightforward installation and maintenance for cost-effective temperature management solutions.
