Example 2 with full speed range from 30rps (1800rpm) to 140rps (8400rpm)
Safeties required
High-pressure switch, Low pressure switch, Discharge gas thermostat set @135°C (275°F) if
necessary see Discharge temperature protection.
Drive setting
No parameter change required, keep default value
Envelope control
The unit controller continuously measures evaporating and condensing temperatures, as well as
maintains compressor speeds according to
specific
zone restrictions.
