Resideo TL8230A1003 Thermostat

The Resideo TL8230A1003 is a high-performance LineVoltPro 8000 digital thermostat engineered specifically for 208/240 Vac resistive heating systems. This 7-day programmable thermostat features a DPST switching action, effectively breaking both sides of the line for a positive "off" during the shoulder seasons. Designed for contractors who prioritize precision, it provides electronic line voltage control within +/- 1°F, significantly reducing the "swing" common in mechanical bimetal controls. This unit is built to manage electric baseboard heaters, radiant ceilings, and fan-forced convectors with a robust 15 Amp maximum rating, supporting up to 3600 Watts at 240Vac. The 2.67-square-inch backlit display offers high visibility in low-light conditions, while the soundproofed induction housing eliminates the loud clicking associated with traditional relays. With a temperature setting range of 40-86°F, it ensures reliable operation in demanding residential and light commercial applications.

• Precise Temperature Control: Electronic thermistor sensing maintains a tight differential for improved comfort and energy-efficient heating.
• Double Pole Disconnect: The DPST switching action ensures safety by disconnecting both L1 and L2 lines when the unit is set to off.
• Silent Operation: Soundproofed construction makes this an ideal choice for bedrooms and quiet living areas where relay noise is an issue.
• Flexible Programming: 7-day scheduling with four periods per day allows for customized temperature setbacks to reduce utility costs.
• Non-Volatile Memory: Preserves user settings during power interruptions, requiring only the clock to be reset after extended outages.

Is the Resideo TL8230A1003 compatible with 120V systems?
No, this model is specifically rated for 208/240 Vac line voltage applications only. For 120V systems, a single-pole alternative is required.

Does this thermostat require batteries?
This is a hardwired unit that draws power directly from the line; it does not require or utilize batteries for operation or memory retention.

Can I use this with a fan-forced heater?
Yes, the Resideo TL8230A1003 is compatible with fan-forced convectors, electric baseboards, and radiant heating systems, provided the total load does not exceed 15 Amps.
