Honeywell TL8230A1003/U – Frequently Asked Questions

1) Will the Honeywell TL8230A1003/U work on a 240V electric baseboard heater?
Yes. The TL8230A1003/U is built for line voltage electric heat at 208 or 240 VAC, rated 15 amps max, 3600 watts at 240 VAC and 3120 watts at 208 VAC. It suits electric baseboards, convectors and fan forced heaters with resistive rated loads. Add up the wattage of every heater on the circuit it controls and stay under those limits.
2) Is this Honeywell line voltage thermostat single pole or double pole?
Double pole. The TL8230A1003/U uses a DPST switching action, so it breaks both legs of the 240V circuit when the heat is satisfied or the thermostat is switched off. If your existing stat has only two wires coming out of the wall, it is a single pole and this is not a direct swap; a double pole needs four conductors.
3) Is the Honeywell TL8230A1003/U approved for use in Canada?
It carries cCSAus approval under File Number LR76030 and is compliant to CAN/CSA-C828-06, plus UL Listing 9R12 under File Number E183695. That covers both US and Canadian installations for spec work.
4) How does the TL8230A1003/U wire in, screw terminals or leads?
It comes with 5.5 inch (140 mm) tinned copper lead wires, so you splice to the heater conductors with wire nuts in the box rather than landing screws. Plan for enough box depth to fold four splices behind the body, which is 7/8 in. deep.
5) Can this thermostat be mounted sideways or on a horizontal box?
No. The TL8230A1003/U is a vertical mount unit, measuring 4 7/8 in. high x 2 3/4 in. wide x 7/8 in. deep. Mounting it on its side will leave the display and the mounting holes out of orientation.
6) What temperature range can tenants set on the TL8230A1003/U?
The setpoint range is 40 F to 86 F (5 C to 30 C), held to within plus or minus 1 F by a thermistor sensor. The thermostat itself is rated to operate in ambient conditions from 32 F to 122 F (0 C to 50 C), so it is fine in an unheated space over the summer shutdown.
7) Does this Honeywell baseboard thermostat need batteries, and will the program survive a power outage?
No batteries. The TL8230A1003/U is powered from the line and is maintenance free, so there is nothing to change out across a portfolio of units. It is a 7 day programmable control with an early start feature that brings the space to the programmed temperature by the programmed time.
8) Will this thermostat match the other white devices in an apartment unit, and is the display readable in a dim hallway?
Finish is Premier White, which lines up with standard white device plates. The display is backlit and 2.67 sq in., readable in low light, and there is a heating indicator so a tenant can see at a glance that the heat is calling.
9) Tenants complain about clicking from the old baseboard thermostats. Does this one fix that?
It is soundproofed specifically to cut the clicking that mechanical line voltage stats make as they cycle. It also has an On/Off or On/Standby switch so units can be shut down at the end of the heating season without pulling the breaker.
