    Water heater thermostats
    Hello, Could anyone suggest what these specifications mean: Wh9 thermostat, 208V through 440/480V. These describe a lower thermostat for an electrical water heater. Do these voltages mean the maximum voltage allowed in the circuit? And why are there several voltages in the description? Appreciate any advice. Thanks, H.
