Negative Positive
Title: Functions, but too big of temp swings.
Review: This mechanical based thermostat has a huge temperature swing to it. It wired in-line wity my electric heater (high voltage - 240v, 2 powered lines in and out) easily. When I think it should turn it, I have to physically tap the dial and the heater turns on. When I think it should be done, I have to physically tap it again to turn off. Temp swings from below 68F to above 72F without me intervening with a tap. Looking for another thermostat now that is digital based.
