For technical reasons, the temperature is not expressed in degrees but by a line increasing in thickness. We therefore recommend that when starting up the appliance, the thermostat be turned to maximum (thick green line = maximum cold, thick pink line = maximum hot). When the desired temperature has been reached, move the cursor slowly away from the maximum cold or maximum hot position until the appliance is switched off by operation of the thermostat. In this way the appliance has been programmed with the exact temperature degree required, which is then maintained automatically by the thermostat. This appliance is fitted with a safety device that blocks its operation if at least 3 minutes have not elapsed from when it was last switched off. 26 HOW TO START UP THE CONDITIONER (see control panel on the opposite page) Plug the appliance into the mains. signal lamp goes Press the key for the function required: AIR-COOL.
