Appendix 1
Interaction between internal and external start/stop functions
and active functions.
Connection between the evaporating temperature and the
actuator’s temperature (the values are approximate).
n01: The highest regulated room temperature will have a be longing t
o
value which
in turn indicates the value of the n01 setting. Due to tolerances in the actua-
tor, the setting value must be 10 K
higher
than shown in the curve.
n02: The lowest occurring suction pressure will have a belonging t
o
value which in
turn indicates the value of the n02 setting. Due to tolerances in the actuator,
the setting value must be 10 K
lower
than shown in the curve.

Appendix 2
Cable length for the
CVQ
actuator
The actuator must be supplied with 24 V a.c. ± 10%.
To avoid excessive voltage loss in the cable to the actuator, use a
thicker cable for large distances.
