SCHEDULE ANTICIPATION START-UP

Function
The CLIMATIC™ 60 allows the start up of the unit before the pre-specifi ed hour of the fi rst zone (zone 1) of the day.
Description
This function is able to start the unit during zone 0 earlier if the outdoor temperature is under a specify threshold. The typical application
is to start the unit in heating mode if the weather is too cold compare to the actual season.
zone 1 start time (h)
(2142) Z1 start time
Calculates Z1 start time
Example:
• (2142): zone 1 start time: 8h00,
• (2161): foot anticipation: 10.0°C,
• (2162): gradient anticipation: 10 mm/°C.
In this example the foot is set to the value 10.0°C, which means zone 1 will always start at 8h00 if the outside air temperature is higher
than 10.0°C. If the outside air temperature is less than 10.0°C zone 1 will start according to the selected gradient and the difference
between the foot value and the actual outside air temperature (10.0 - 7.0 = 3.0 x 10 = 30 min). Then, the new start time for zone 1 is 7h30.
Settings
The different settings to adjust the anticipation are available in the menu:
(2161): Foot anticipation
(2162): radient anticipation
