Breaking 120v VS 240v Thermostat Warnings and Training.

[@Sparky-ww5re]

Thank you for pointing out the importance of a positive OFF. Myself being a journeyman sparky I've installed my share of baseboard heaters, all but maybe 2 of them were 240 volt units and I've always used 120V thermostats because they were cheaper than the double pole thermostats, and the homeowners never wanted to spend more than necessary. Most of the heaters I've installed were in additions like a spare bedroom or new bathroom (wall heater for the bathrooms) . Never had any issues with shocks or fire hazards. Inspectors were okay with it.

here in WA you must replace any single pole stats with a two pole. and never allowed on a new construction.

Ran across a wild set up last month. Fed Pacific stat with a common. Took me a min to understand how the system was laid out and was prevalent throughout this entire community of townhouse built in 1984. 120v was always laying on the heating coil at all times. Really weird way of laying out a system.
