Recirculation - Daikin UATYA-BBAY1 Manual De Operación

5.8.5

Recirculation

Full air recycling at system start-up or after a washing cycle is intended to achieve the temperature and humidity
setpoints more quickly.
If air recycling only is required at unit start-up, parameter "DA52" must be set to "2".
If parameter "DA52" is set to "3", a washing cycle is performed before recycling.
While recycling is in progress, the controller keeps the exhaust air and external air dampers closed and it keeps the
recycled air damper open for the time setpoint stored in parameter "DA55".
If the value in parameter "DA53" is set to "0", the washing cycle takes place without any thermoregulation of the air.
If the value in parameter "DA53" is set to "1", thermoregulation is active.
While recycling is in progress, a button flashes on the main screen which is pressed to stop the cycle manually before
the time set in parameter "DA55" elapses.
