For entering water temperatures below 7.5 °C at start-up, contact Carrier.
** If the leaving water temperature is below 5 °C, a frost protection solution must
be used. Please refer to option 6 for evaporator leaving water low-temperature
applications (< 5 °C).
*** The minimum entering air temperature is based on the drycooler selection.
**** The maximum entering air temperature is based on the drycooler selection.
† For applications with a low condenser entering air temperature the use of a
three-way valve is recommended. This thre-way valve can be controlled by the
0-10 V analogue output of the Pro- control.
