Resideo TH105PLUS Programmable Thermostat
The Resideo TH105PLUS is a high-performance line voltage programmable thermostat purposefully engineered for precise control of electric baseboard heaters, convectors, and fan-forced heating systems. Operating on a 120/240 Vac supply, this unit features advanced Triac switching technology, which provides 100% silent operation by eliminating the mechanical clicking common in traditional relay-based models. Industrial-grade Triac for electric heat ensures a tighter temperature swing (±0.27°F), preventing the "cold-hot" cycles that reduce comfort and increase energy consumption.
For professional contractors, the 5-2 day programming allows for distinct weekday and weekend schedules with up to four daily periods. The vertical mounting design fits standard electrical boxes, while the battery-free backup preserves setpoints during power interruptions without requiring maintenance visits. The backlit display and integrated heating power indicator provide real-time feedback on system demand, making it an ideal SPST thermostat for high-density residential and light commercial applications where noise reduction and reliability are paramount.
- Silent Triac Switching: Eliminates mechanical noise, making it the superior choice for bedrooms and quiet spaces.
- High Accuracy Control: Maintains temperature within ±0.27°F to eliminate fluctuations and maximize efficiency.
- No Battery Required: Hardwired resideo TH105PLUS/U design utilizes a permanent memory to save schedules during outages.
- Broad Compatibility: Supports resistive loads up to 14.6 Amps (3500W @ 240V / 1750W @ 120V).
Does the TH105PLUS work with fan-forced heaters?
Yes, this model features a selectable 15-second or 5-minute heating cycle. The 5-minute cycle is specifically designed to protect the motor and optimize the performance of fan-forced heaters.
Can this thermostat be used with central heating systems?
No, the Resideo TH105PLUS is designed exclusively for line voltage (120/240V) electric heating. It cannot drive low-voltage 24V HVAC systems or inductive loads like contactors and relays.
What is the benefit of the heating power indicator?
The on-screen indicator displays the percentage of heating intensity being used. This helps technicians verify system load and allows users to monitor their energy consumption in real-time.
