Daikin EWADC16BJYNN [222/346] Lvg water temp

Functional Control ESIE07-04

2–82 Part 2 – Functional Description

Outdoor ambient

temperature reset

The OAT mode can be used to modify the setpoint in function of the ambient temperature. The user is

able to choose to use the OAT mode or not. The result of using the ambient mode is that the unit will

be used more efficiently and that the modified setpoint will be displayed under the normal setpoint.

The OAT setpoint parameters and function can be set in the user menu.

This function is only available when the optional pCOe (expansion board) is present. This is because

the ambient sensor is connected to this pCOe.
