All heater model variants include a toggle switch which has three positions. The toggle switch position options are Low, Off and High power.
When high power is selected the heater will perform as described here. When the heater is switched into low power mode the heater will use one third (1/3) to one half (1/2) of the power described here.
These heaters use different numbers of heating elements and the toggle switch from low to high determines how many elements are powered on. For heaters that include two heating elements the low toggle position will power just one element, the high position powers both.
Heaters with three elements with the toggle in the low position two of the three elements will be powered.
Heaters built with four elements with the toggle in the low position two heating elements will receive power while the other two remain powered off.
