Gradual door response: the unit responds to the opening
and closing of the door. The speed of response is based on
the open/closed ratio.
Note:
n
With the door closed, the unit can be set to keep
the room at a minimal room temperature.
Note:
n
In some situations the unit is not active, even though
it is on.
1.3.4 i-sense infra red technology
The i-sense infra red technology makes it possible to use the
automatic CHIPS control without adding external controls
such as an outdoor temperature sensor and a door contact
switch.
Next to the discharge grille is an IR sensor which measures
the temperature in a strip of 8 planes perpendicular to the
door opening. As a result, the sensor provides the controller
with diverse information:
Note:
n
The temperature of a floor surface changes gradually.
•
indoor temperature (T8)
•
outdoor temperature (lowest measured value of T1, T2
and T3)
Note:
n
An outdoor temperature is only measured if the IR
sensor recognises the door as being open.
•
door position
If the difference between T5 and T1, T2 or T3 is at least
3°C is, it is assumed that the door is open.
Note:
n
An outdoor temperature can only be recognised if
the unit is on and climate separation is active.
•
signal for quick start or 30 minutes on (T7 and T8)
If the measured value briefly changes, it is assumed that
someone is walking below the sensor.
