Volts
The computer chips in your tankless water heater are
programmed with the expectation that your incoming line
voltage is 240 volts. If you have less than 240 volts [i.e.
208V or 220V], it may aect the reading on your water
heater’s digital display and cause it to read slightly higher
than the actual output temperature. To compensate
for this, increase the setting on your water heater if you
need or want hotter water.
