Can this thermostat be installed with multiple Cadet baseboard heaters? Installed in parallel on the same circuit, similar to the BTF1. For example (1) 4F1000W & (2) 2F350W baseboard heaters.

Asked by: glo
Glo, This thermostat has a low setting but no off. So if you have it turned all the way down, the heater will not provide heat unless the room temperature drops to about 50 degrees F. If you want an off setting, you want the T522-W thermostat: https://www.homedepot.com/p/Cadet-Double-Pole-22-Amp-120-Volt-240-Volt-Wall-Mount-Mechanical-Non-programmable-Thermostat-in-White-T522-W/303733757

Your description says the set points for this device are 40 to 80 deg F. Cadet's own website says it is 50 to 90 deg. The picture here also seems to indicate 50 to 90. Which is correct?

The photo of the dial displays the correct temperature range.

Single-Pole 22 Amp 120-Volt/240-Volt Wall-Mount Mechanical Non-Programmable Thermostat in White is rated 4.5 out of 5 by 17.

( unless you turn off the breaker ) but with only two wires, they are much easier to install. price was also reasonable.
