Honeywell TL7235A1003/U – Frequently Asked Questions

1) Will the Honeywell TL7235A1003/U work on a 240V electric baseboard heater?
Yes. The TL7235A1003/U is a line voltage thermostat for 208 or 240 VAC circuits, rated 15 amps max, which works out to 3600 watts at 240 VAC and 3120 watts at 208 VAC. Add up the wattage of every heater on the circuit and stay under that number. It is built for electric baseboards, convectors and fan forced heaters (resistive rated loads).
2) Is the TL7235A1003/U single pole or double pole, and does that matter?
It is double pole, DPST switching through a relay. That means both legs of the 240V circuit break when the thermostat is satisfied or switched off, so the heater is fully de-energized. Single pole units leave one leg hot. If local code or your electrician calls for a double pole disconnect at the thermostat, this is the one you want. Note it also has an on/off switch to shut the heat down at the end of the season.
3) Can I wire this Honeywell line voltage thermostat in place of my old mechanical baseboard stat?
Connection is by four 5.5 in. (140 mm) tinned copper lead wires, so it wires with wire nuts the same way a mechanical line voltage stat does. Two differences to plan for: it must be a double pole application (both heater legs switched), and it mounts vertically only, so a horizontal box orientation will not work. No batteries or common wire needed, it is powered from the line.
4) Will the TL7235A1003/U cover the wall plate opening left by my old thermostat?
The body measures 4 7/8 in. high x 2 3/4 in. wide x 7/8 in. deep (124 x 70 x 23 mm). It is a tall, narrow vertical profile, so it covers a standard vertical single gang opening but will not hide a wide horizontal cutout. Finish is Premier White.
5) How low can I set this thermostat for an unoccupied unit or a garage?
Setpoint range on the TL7235A1003/U runs 40 F to 86 F (5 C to 30 C), so 40 F is your minimum, which is enough to hold a vacant apartment or a shop above freezing. The unit itself is rated to operate in ambient conditions from 32 F to 122 F (0 C to 50 C). For unheated spaces that drop below freezing, that ambient limit is the one that governs.
6) Is the Honeywell TL7235A1003/U programmable, and should I get a programmable model instead?
It is non-programmable, one heat stage, with a backlit display and manual setpoint only. That is what you want for rentals, common areas, and any unit where tenants or staff should not be fighting a schedule, and it needs no batteries so there is no maintenance call when they die. If you want setback scheduling for energy savings in an owner-occupied space, look at a programmable line voltage model instead.
7) Does this Honeywell baseboard thermostat carry a UL or CSA listing for a commercial job?
Both. It is UL Listed under 9R12, file number E183695, and carries cCSAus approval under file LR76030, compliant to CAN/CSA-C828-06. That covers it for use in the US and Canada, which matters if you are submitting for a spec-driven or institutional install.
8) How tight does this thermostat hold room temperature compared to a mechanical stat?
The TL7235A1003/U uses a thermistor sensor with electronic control accurate to plus or minus 1 F (plus or minus 0.5 C). That is a much narrower swing than a bimetal mechanical stat, which is where the claimed savings of up to 10 percent on heating bills come from. It is also soundproofed, so you avoid the clicking tenants complain about.
