Space Pi Filament Dry Box Plus - low temperature

Hi,
The dryer is in my workshop and the ambient temperature is close to the outside temperature. When the room temperature is under 15°C, the dryer prints “EA” instead of the box temperature and the fan is off. It may easily take 1 hour to reach 15 °C.
When the box temperature is at least 15°C, it heats very quickly and everything works fine.
Preventing the heating because it is too cold seems a bit counterintuitive. Is there a way to make the dryer heat whatever the outside temperature is?
