Indoor Unit (IDU)
The boiler electric elements are rated at 240 volts. If operated at 208, there will be an approximate 25% reduced capacity. Also, the internal transformer may or may not adequately operate the control system from 208 volt source. Voltage measurement between R and C must be greater than 23VAC when the system is in complete operational mode.

Working of Boiler – Explanation, Parts, Working Principle
The boiler is a closed vessel, where the water is stored. Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler's basic principle is to convert water into steam with heat energy.
