MAXIMUM COMPRESSOR SPEED AS A FUNCTION OF THE EXTERNAL TEMPERATURE
The maximum compressor speed can be set differently based on the external air temperature, within 2 limits that can be set using parameters
133X
“Ext.temperature high threshold:” and
133Y
“Ext.temperature low threshold:”, as follows:
- if External air T <
133Y
, maximum speed = par.
133W
“Max speed inverter custom 2:”
- if
133Y
<External air T <
133X
, maximum speed = par.
1368
“Max speed inverter:”
- if External air T>
133Y
, maximum speed = par.
133V
“Max speed inverter custom:”
Note: for parameter
133Y
, the hysteresis is 0.5°C fixed right; for parameter
133X
the hysteresis is 0.5°C fixed left.
See the following chart as an example.
For the default values of the various parameters, see the parameters table
