Start of controller
When the electric wires have been connected to the control-
ler, the following points have to be attended to before the
regulation starts:
1. Switch off the external ON/OFF switch that starts and stops
the regulation.
2. Follow the menu survey and set the various parameters to
the required values.
3. Switch on the external ON/OFF switch, and regulation will
start.
If the temperature fluctuates
When the refrigerating system has been made to work
steadily, the controller's factory-set control parameters should
in most cases provide a stable and relatively fast regulating
system.
If the system on the other hand oscillates, you must register
the periods of oscillation and compare them with the set
integration time T
, and then make a couple of adjustments in
n
the indicated parameters.

4. If the system has been fitted with a thermostatic expansion
valve, it must be set to minimum stable superheating. (If a
specific T0 is required for the adjustment of the expansion
valve, the two setting values for the actuator temperature
(n01 and n02) can be set to the belonging value while the
adjustment of the expansion valve is carried out.
Remember to reset the values).
5. Follow the actual room temperature on the display.
(Use a data collection system, if you like, so that you can
follow the temperature performance).
