Product Highlights
Description
The Honeywell TL8230A1003 LineVoltPro 8000 thermostat delivers precision temperature control for 208V and 240V electric baseboard heaters, radiant ceiling heat, convectors, and fan-forced heaters. This programmable line voltage thermostat features 7-day scheduling that helps reduce annual heating costs by up to 10 percent when used as directed. Designed for residential and light commercial electric heating applications, it combines electronic accuracy within plus or minus 1 degree Fahrenheit with a user-friendly digital interface. The double-pole (DPST) design provides safe, complete circuit isolation for line voltage electric heating systems.
Key Features & Benefits
- 7-Day Programming: Set unique temperature schedules for each day of the week with four programmable time periods daily, allowing you to heat only when and where you need it for maximum energy savings.
- Electronic Temperature Control: Maintains accuracy within plus or minus 1 degree Fahrenheit, eliminating the temperature swings common with mechanical thermostats and keeping your space consistently comfortable.
- On-Demand Backlight Display: Large, clear digital screen lights up when you press a button, making it easy to read in any lighting condition from dim hallways to bright rooms.
- Early Start Function: Calculates when to activate heating so your programmed temperature is reached exactly when scheduled, ensuring comfort the moment you need it.
- Soundproofed Operation: Reduces the clicking noise commonly heard with conventional line voltage thermostats, providing quieter operation in bedrooms and living spaces.
- Heating Indicator Light: At-a-glance confirmation shows when the heating system is actively running, so you always know your system status.
- On/Off Switch: Built-in switch lets you turn the thermostat completely off at the end of the heating season, preventing accidental activation during warmer months.
- Double Pole Design: DPST switch configuration breaks both hot legs of 208V or 240V circuits for complete electrical isolation and enhanced safety.
Compatibility & Requirements
The TL8230A1003 is designed for line voltage electric heating systems operating at 208V or 240V AC, 50/60 Hz. It controls resistive-rated electric baseboard heaters, radiant ceiling heating panels, convectors, and fan-forced heaters. The thermostat is rated for 15 amps at 208V (3120 watts) or 15 amps at 240V (3600 watts). It requires hardwired installation and mounts vertically on a standard electrical box. The unit uses 5.5-inch tinned copper leadwires for connection and does not require batteries.
Installation & Care
The thermostat mounts vertically in a standard electrical box using the included hardware. Installation requires connecting the line voltage power supply wires to the line terminals and the heating load wires to the load terminals, following the double-pole wiring configuration shown in the installation instructions. The unit measures 4 7/8 inches high by 2 3/4 inches wide by 7/8 inch deep. Consult the installation manual for detailed wiring diagrams and safety precautions before beginning installation.

Frequently Asked Questions
Q: Can this thermostat be programmed separately for each day of the week?
A: Yes, the TL8230A1003 offers true 7-day programming, allowing you to set a unique schedule for each individual day. Unlike 5-2 day programmable models, this thermostat lets you program Saturday differently from Sunday or any weekday differently from another. Each day supports up to four separate time periods with different temperature setpoints.
Q: Does this thermostat need batteries?
A: No, the TL8230A1003 is hardwired directly to your line voltage electric heating system and does not require batteries. It draws power from the 208V or 240V electrical circuit, so it remains operational as long as the circuit breaker is on.

Verified Reply- SupplyHouseHello Stan, unfortunately no. Since they are two different types of line volt thermostats they would not replace one another as the TH115AFGA is still a available part.

Q: RE: TL8230A1003 DESCRIPTION SHOWS 4 WIRES. MY PERSENT STAT HAS 2 WIRES. WHY ARE THERE 4 WIRES
Asked by GARRY 11 years ago
Add your answer
Hi, Garry - The thermostat is constructed as a two-pole (meaning it can switch two live lines) single-throw (meaing on-off). The one of the two black wires are for one 'hot' leg of the power source being used (204-240 VAC) and the other black goes to the unit being supplied with power. Same applies to the white wires. So, to hook it up to a 204-240 VAC heater, remove the old thermostat and disconnect the wires. Usually, in a two-wire system, a black wire from the main supply goes to one side of the switch and the other black lead hooks to one side of the device being used. The white wires are most often tied together and go directly from the power supply (fuse box) to the heater. In this configuration, the switch being used is a single-pole single-throw, meaning only one leg of the supply line is being switched. You'll want to make sure that you separate the main power supply wires from the heater wires so you have a white and black coming from the fuse box (or junction box) and a white and black wire coming from the heater. Now, connect the black power supply lead to one black lead on the thermostat (it should show as "line" and connect the white lead from the power supply (or junction box) to the white lead shown as "line" on the thermostat. You can now connect the leads from the heater to the corresponding white and black leads on the thermostat (shown as "load"). Make sure that any copper ground wires are connected for shock protection and you should be set to go. These are great thermostats and I've been very happy with the three I purchased several heating season's ago. Hope they meet your needs, as well.

Q: I am questioning if my baseboards will draw too much wattage/too many Amps. I have 2 8' baseboards, and one 4' baseboard in series. Are they too much for this thermostat?
Asked by MN Cabin guy 11 years ago
Add your answer
Verified Reply- Supplyhouse Staffwe would need the electrical specs on the heaters, not the sizes.
The load calculation baseboard heat is 250 Watts per foot (as seen fit by those in the electrical installation/design field). Then get rated components that can withstand 125% of that calculated load. So, you have a total of 20 feet of baseboard heat. That is 5000 watts. An additional 25% is 1250 watts. 6250W / 240V = 26 Amps. These are rated for 15 amps each. Side note: your heaters are not wired in series (at least, they should not be). If they are on the same circuit then that circuit is a 30A circuit. You are likely better having a t-stat for each of the heating units. Then none of those units will exceed the amp rating of this t-stat.

Q: Can I connect more than one baseboard electric heater to this thermostat?
Asked by David 12 years ago
Add your answer
Yes, as long as you don't exceed the wattage rating of the thermostat. Typically an electric baseboard heater is 250 watts per foot of length at 240 volts ac. So a 5 foot baseboard would be 1250 watts at 240vac. Two 5 footers would be 2500 watts. Which would be about 10.5 amps. Two 8 footers would be 4000 watts and 16.5 amps. Sent from my Verizon Wireless 4G LTE DROID
yes, as long as you don't exceed the spec for the thermostat.
I have 3 baseboard heaters connected to mine. Just be careful that the combined wattage of the heaters does not exceed the capacity of the thermostat. Sent from my iPad
