Room Operator Display Green Leaf Function
Energy efficiency is indicated by a leaf icon. The icon is either Green or Red. A green leaf signals to the occupant that
the Artus is operating at its most optimised energy efficient mode. A red leaf indicates that setpoint parameters have
changed locally (a manual override). The red leaf indication does not mean that the unit is in fault, it’s just that the unit
could be operating more efficiently. If indicating red, the unit can be reset back to its normal, energy efficient operating
mode by pressing the leaf button on the room operator unit display.
Return Air Temperature Sensor
The return air temperature sensor shall be fitted to the return air of the unit. The sensor shall be positioned within the
unit under the filters.
Room Sensor (optional)
Passive sensors for acquiring the temperature in the room instead of the return air temperature sensor in the ceiling
void. The room sensor is to be positioned on an inner wall of the space to be treated. It must not be obstructed by items
such as recesses, shelves, curtains etc. and must not be opposite or near heat sources (both hot or cold). The unit must
not be exposed to direct sunlight or draughts.
The room sensor shall be wired back to the unit and replaces the unit’s return air temperature sensor. To install, simply
unwire the factory return air temperature sensor with the tool provided and replace with the 2 core cable from the room
sensor. There is a grommeted hole on the side of the unit adjacent to the connection points where the cable can be fed
into the unit. Do not coil excess cable within the unit.
