Cleaning The Exchanger - LU-VE Emeritus LU1W Manual De Usuario

8.3
The cleaning function of the exchanger activates the fans with an inverted rotation direction. The function only starts
when the unit is on.
Cleaning can be programmed via parameter PC01; cleaning is performed daily or weekly, depending on the setting:
•
Daily cleaning: with parameter PC01 = 1, cleaning is performed every day at the preset time (parameter
PC02).
•
Weekly cleaning: with parameter PC01 = 2, cleaning is performed weekly on the set day (parameter PC03)
and set time (parameter PC02).
When the cleaning procedure is activated, the fans are switched off for a fixed time of 60 seconds and then turned on
for anti-rotation PC05. After finishing the procedure, they remain off for a further 60 seconds before returning to the
normal setting.
You can also start the cleaning cycle manually from the ADVANCED → MANUAL menu. On the CLEANING screen, move
the cursor over the UP and DOWN keys in the Fans window to Run, then press ENTER.
