Heating a room to the preferred temperature
Note: Bear in mind that factors such as the size of the room, the outside temperature
and how well the building is insulated, all affect the ability of the heater to warm
the room up. If the room is too large the ability of the heater to warm it up to
the desired temperature may be insufficient. The temperature range of the thermostat
is approx. 5–35 °C.
