Par CO06 = 2 inverse action with sequential step
1= the steps are turned on in sequential mode, the outputs are anabled or disabled depending on the output polarity. In case of
thermoregulation request one of the step is turned on or off while the other steps do not change their status.
Eg: # 1 capacity compressor with 3 partializations: 4 Power steps.

ATTENTION
When working with capacity control in sequential step in direct or reverse modes: if the power requested is 50% and 75% the unit turn
on also the step 25% that must be enabled to make run the other two.

Par. CO07
configuration of the start-up with minimum load and compressor type.
It allows to configurate the 1
st
partialization valve of the compressor that can be the partialization start-up valve of an alternative
compressor or the minimum load for screw compressor.
In this way the lower value of partialization (normally is configured as the 1
st
output with the 25%) can be used as minimum start-up load
and also as thermoregulation step or only as minimum start-up load and never as thermoregulation step.
EXAMPLE
Having one compressor with 3 partializations, at the compressor start-up, with
CO07=0
, the partialization valve is enabled only for the
time CO13 but it won’t be never used during the thermoregulation. After the compressor stops running the time CO13 will be reloaded.
Having one compressor with 3 partializations, at the compressor start-up, with
CO07=1
, the partialization valve is enabled for the time
CO13 and it will be considered also as thermoregulation step. After the compressor stops running the time CO13 will be reloaded.
