C7000 INSTRUCTIONS fOR a/C UNITS
External Setpoint:
Using the sensor purposes 17 and 18 an external setpoint can be provided.
The external setpoint takes priority over the internal setpoint.
NOTICE
For dry cooler control you have to configure an outside temperature sensor
and a water temperature sensor.
You need two water temperature sensors for:
1. GCW-units with dry coolers
Water temperature 1 is always the temperature for the CW-circuit.
Water temperature 2 is the cooling water temperature, by which the dry coo-
lers are controlled.
2. CW2-units
Water temperature 1 is always the temperature for the CW-valve which is acti-
ve, when no change-over has taken place (no voltage at DIN 3).
Water temperature 2 is the temperature for the second CW-valve, which is
active after a change-over.
