5. Configuration
First steps
1. When several units shall operate in a bus: Establish bus wiring and configure bus.
2. Check the equipment by command "equip".
3. Configure additional components like e.g. glycol pump, drycooler, outside temperature sensor.
At the C7000AT you can do this in the Config-level in the submenus of the menu point "Components". Part
of the configuration is the activation of the component, the allocation of an output for the component cont-
rol, the assignment of an alarm input and setting the start value / hysteresis.
4. Calibrate the sensors by reference instruments (menu Operate/Components/Sensor),
important for condensation pressure sensor.
5. Adjust setpoints.
6. Adjust special operating modes like week program, zone operation.
