3.9 Floating Setpoint

3.9.1 Floating Setpoint - Ambient Mode

Introduction The ambient mode can be used to modify the setpoint in function of the ambient temperature.

The user is able to choose to use the floating setpoint 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 floating setpoint parameters and function can be set in the user floating setpoint settings menu.

Explanation When in cooling mode the load of the unit drops (by drop in outdoor temperature), then the setpoint

will be changed upwards by the floating setpoint value. Because of this the unit will evaporate at a

higher temperature and thus the performance of the unit will be better.

Remark: When you use the floating setpoint, the value of the setpoint on the readout and set point

menu can be different. The readout screen will show the calculated value and the setpoint screen the

set value.
