Fantroll
A step control is used; fan steps are activated or deactivated to keep compressor operating
conditions within the allowed envelope.
Fan steps are activated or deactivated keeping condensing (or evaporating pressure) change
to a minimum; to do this one next fan is started or stopped at time.
Fans are connected to steps (digital outputs) according to the scheme in table below

6.20.1.1.1. Control of condensing pressure
A stage up is executed (the next stage is activated) if the condensing saturated temperature
(saturated temperature at discharge pressure) exceeds the target setpoint (default 43.3 °C (110 F))
by an amount equal to a stage up dead band by a time depending by the difference between the
reached values and the target setpoint plus stage up dead band (high condensing temperature error).
In particular the stage up is executed when the integral of the high condensing temperature
error reaches the value 50 °C x sec (90 Fxsec).
At the same manner a stage down is executed (the previous stage is activated) if the
condensing saturated temperature falls below the target setpoint by an amount equal to a stage
down dead band by a time depending by the difference between the reached the target setpoint
minus the stage down dead band values and the reached value (low condensing temperature error).
In particular the stage down is executed when the integral of the low condensing
temperature error reaches the value 14 °Cxsec (25.2 Fxsec).
The condensing temperature error integral is reset to zero when condensing temperature is
within the deadband or a new stage is activated.
