Setting Up The Sliding Temperature - Daikin DCM601A51 User Manual

8-5 Setting up the Sliding Temperature

Sliding Temperature is a function that changes the indoor unit setpoint in accordance with the
changes in the outdoor temperature so that the difference between the outdoor and indoor
temperatures is not excessive in rooms with direct access to/from outside the building. This function
works only when the indoor unit is working in Cool mode.
The setpoint of an indoor unit registered with a Sliding Temperature group you have created and
have this function enabled may change every 5 minutes depending on the outdoor temperature
measured at the Ai management point.
The outdoor temperature and setpoint are linked through the following expressions:
• When the outdoor temperature is higher than the upper limit outdoor temperature
Setpoint = Upper limit setpoint
• When the outdoor temperature is lower than the lower limit outdoor temperature
Setpoint = Lower limit setpoint
• When the outdoor temperature is within the range specified by the upper and limits of the outdoor
temperature
Setpoint = (Outdoor temperature – Lower limit outdoor temperature) × (Upper limit setpoint –
Lower limit setpoint) / (Upper limit outdoor temperature – Lower limit outdoor temperature) +
Lower limit setpoint
NOTE
• The value of the calculated setpoint is round off.
