6.20.4.
Speedtroll
A mixed step-VSD control are used; the first fans step are managed using a VSD (with
related PID control), next steps are activated as in the step control, only if the cumulated stage-up
and stage-down error is reached and the VSD output is at maximum or minimum respectively.
6.20.5.
Double VSD
Two VSD are managed to keep controlled parameter at a setpoint; the second VSD are
activated when the first one reaches the maximum speed and the PID control requires greater air
flow
6.20.6.
Fans control at startup in heating mode
At the compressors start in heating mode fans are started before that the compressors begin
their normal start up sequence if the outside ambient temperature is below a fixed temperature of
10.0°C (50.0F). If the condensation control is either speedtroll or fantroll each step is activated after
a fixed delay of 6 seconds. The control is released to automatic control if the outside ambient
temperature is greater than a fixed threshold of 15.0°C (59.0F).
6.21. Other functions
The following functions are implemented.
6.21.1.
Hot Chilled Water Start
This feature will allow the unit startup also in case of high evaporator outlet water
temperature.
It will not allow the compressors loading above an adjustable percentage until the
evaporator leaving water temperature falls below an adjustable threshold; another compressor is
enabled to start when the others are limited.
6.21.2.
Fan Silent Mode
This feature will allow to reduce unit noise limiting fans speed (only in case of VSD fan
control) on the base of a time schedule. A maximum output voltage for the VSD could be set for
FSM operations (default value 6.0V).
6.21.3.
Double evaporator units
This feature will allow to limit freezing problems on units with two evaporators (3 and 4
compressors units).
In this case compressors are started alternatively on the two evaporators.
