the message “critical supply temperature” is shown on the remote control. By activating this function it is possible to choose how long low temperature
may be supplied before the message is shown.

Night ventilation – room cooling by bringing in night-time air. It is normally on, where outdoor temperature in the daytime is >26°C, and in the night-time
it is <16°C. In the night-time room temperature must be >17°C. Every 3 hours the unit switches on for 5 minutes: it measures the supply air and room
temperature. If the room temperature becomes higher than the desired temperature 5 minutes later, and the outdoor temperature is lower than the set
night-time outdoor temperature, the unit is on until the outdoor temperature starts exceeding the set night-time outdoor temperature OR the room is
cooled down to the set temperature. Standard parameters can be changed in the service menu.

• “day T” – {15-40}°C maximum outdoor temperature
• “Night T” – {0-15}°C minimum outdoor temperature
• “Room T” – {10-30}°C room temperature
