heater will operate continuously but during the last one degree the operation will be proportionally reduced
until the required temperature is achieved.
When the red indicator (4) is visible the heater will operate in comfort mode and maintain the higher

comfort mode to economy mode. The red indicator will go out and the green indicator (5) will come on,
the heater then will operate in economy mode and maintain the lower setting (2).
