CLIMATIC RT_UNITARY-IOM-1508-E
COMPONENTS
CONDENSER FAN
Function
The CLIMATIC is used to maintain the high pressure as stable as possible in order to increase the performance of the unit.
Description
The CLIMATIC uses a PI algorithm to command fan stages or a speed inverter, depending on the unit type.
Moreover, for units with variable speed fans (option), the CLIMATIC controls the fan speed limit which allows progressive adaptation
of the unit to the building load and reduces the noise level - See hereunder operation of «Quiet» and «Auto Quiet»
It also exists a “Fixed “ mode where the fan speed is adjusted to the set point (3523) .
The maximum speed and the fan management can be adjusted according to the schedule mode in order to bene t from the different
fan control types in heating or cooling.
