Optimization
When operation in the heating mode, Daikin VRV systems continue
to circulate a small volume of refrigerant gas through indoor unit that
are in an acceptable condition (thermo-off). As the fan will continue
to run at low speed or set speed, a rise in room temperature is
possible.
Therefore, this function starts / stops the air conditioner based on the
room temperature (intake air temperature) and the set temperature
during heating operation to prevent the temperature rise.
<Overview of Function>
¡
Operation interruption control
When the room temperature for the air conditioner in heating operation becomes
higher than the set tempe 1
°
C, the air conditioner is stopped. However,
because the stop control (operation interruption) by this function is the optimum
control for turning off of the thermo-switch during heating operation, the system
regards this status as in operation, and the screen display on the unit remains “In-
operation.”
∗
After the unit is interrupted by this function, it restarts when the specified
conditions are met. Therefore the user’s explicit stop command is effective.
¡
Operation restart control
When the room temperature for the air conditioner under the stop control by this
function (during heating operation interruption) becomes lower than the set
temperature – 1
°
C, the air conditioner is restarted.
