(The calibration must be done after 12Hours working with the same setting temperature)
- To check the temperature in the room, put a thermometer at 1.5m distance to the floor in the concerned room and wait 1
hour to be sure that the thermometer shows the correct temperature. Then you can enter the value saw on the thermome-
ter with (-◄) or (►+) keys.
