Programmable Thermostat

This replacement thermostat is compatible with the Resideo TH135-01-B/U and similar models, offering reliable low-voltage control for central heating systems. Designed for precise temperature management, this non-programmable electronic thermostat operates on millivolt power and is suitable for gas, oil, electric, radiant, convection, and hot water circulator applications. The unit features three preset temperature modes: Comfort at 20 Degrees C/68 Degrees F, Economy at 18 Degrees C/64 Degrees F, and Vacation at 10 Degrees C/50 Degrees F, allowing facility managers to optimize energy consumption based on occupancy and operational requirements. Users can select between 15- or 20-minute cycle intervals, providing 3 to 4 cycles per hour for responsive temperature regulation. The thermostat offers two operational modes to suit different heating system configurations. Proportional Adaptive Mode analyzes heating cycles to deliver optimal regulation, making it ideal for central heating and radiant heating systems that require sophisticated control. Alternatively, Conventional Mode with Anticipation provides a 0.5 Degrees C deadband and is well-suited for multi-zone installations or furnaces with extended purge cycles. The LCD display clearly shows room temperature and allows easy adjustment of settings for facility staff. This replacement unit provides a cost-effective solution for maintaining consistent climate control in commercial and industrial heating applications where precision and reliability are essential. Compatible with existing Resideo TH135-01-B/U installations, it enables straightforward retrofitting without requiring system modifications.
