unit heaters can be operated from one thermostat pro- vided that the sum of the motor locked rotor currents or the sum of the full load currents does not exceed the electrical rating of the thermostat. The Type 11B09 Reverse-acting Surface Hot Water Control is used to prevent operation of the fans when the steam is off or when the water temperature is too low for proper heating.
