The control panel includes a lithium cell CR1220 with a limited time
resource.
The battery keeps the internal clock running while the unit is disconnected
from power mains. If the unit is disconnected from power supply and the
battery is low, the clock stops and the day and time settings are reset. This
leads to incorrect date and time indication when the unit is on and, as a
result, to incorrect scheduled operation of the unit. In this case, the battery
should be replaced. To replace the battery use a new battery only.
Cell replacement:
1. Disconnect the air handling unit from power supply.
2. Remove the two screws in the bottom of the service panel.
3. Remove the casing cover to enable access to the upper circuit board.
Replace the cell.
4. Assemble the control panel in the reverse order. If the wires from
the terminal block on the upper circuit board are disconnected, be sure to
connect those correct.
Wrong connection of the wires may result in the equipment malfunction.
5. Connect the air handling unit to power mains and set date and time
on the control panel.
