7.13.7 Filter replacement indication
This function calculates the filter contamination level using the operation times of
the respective fan speeds. The necessary filter replacement message is dis-
played and entered as a warning only on the MATRIX OP50 or MATRIX OP51
control panel.
The "filter change" message is indicated after the "service period" or "minimum
service interval" is exceeded or generated by a connected differential pressure
switch.
Confirmation of the warning is followed by the recalculation of the remaining ser-
vice period.
Upon successful filter replacement the internal runtime counter is reset using the
menu selection at the control panel.
7.14 Setting for room air flow (SWIRL)
The menus to calibrate the room air flow and reset the data to default setting
(factory setting) are available via home screen "Additional menus", "Menu
option", "Setting" in the submenu "Rroom air flow"
7.14.1 Calibrate
In this menu, the air-throw depth of cold air can be calibrated in "Automatic" mode.
For this purpose, set the adjustment of the room air flow for any reference point.
The control principle consists of keeping the air-throw depth constant and optimiz-
ing the direction of discharge caused by changing air volume and temperature
conditions, to reduce the risk of draughts.
