Entering/leaving water temperature difference K
(1) For entering water temperatures below 7.5 °C at start-up, contact manufacturer.
(2) 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).
(3) For applications with a condenser entering temperature below 15 °C the use of
a three-way valve is recommended. This three-way valve can be controlled by
the 0-10 V analogue output of the TouchPilot Junior control.
(4) For a water flow rate that corresponds to a maximum water-side temperature
difference of 5 K.

Note: Do not exceed the maximum operating temperature.
(1) A frost protection solution must be used.
(2) For applications with a condenser entering temperature below 15 °C the use of
a three-way valve is recommended. This three-way valve can be controlled by
the 0-10 V analogue output of the TouchPilot Junior control.

operation
(1) For entering water temperatures below 7.5 °C at start-up, contact Carrier.
(2) 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).
(3) The minimum entering air temperature is based on the drycooler selection.
(4) The maximum entering air temperature is based on the drycooler selection.
(5) 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 TouchPilot Junior control.
