Variable Unit Description Default Value Range Field Value

Destage % Percentage of the stabilized speed at which the lag pump 85 0-100

will stop

Destg s Proof timer prior to stopping lag pump 30 0-999

Pr Timer

HD Spd % Lowest speed at which parallel pumps will operate prior 50 0-100

to destaging the lag pump

HD Pr Tm s Proof timer prior to destaging the lag pump when 30 0-999

operating below the HD speed

Table 9: PV Destage Variables

Variable Unit Description Default Value Range Field Value

Pump GPM Maximum flow allowable prior to starting a lag pump 0 0-9999

Max Flow

Stg Proof s Proof timer prior to end of curve staging 30 0-999

Flow GPM Flow rate of constant speed pump supplying variable 0 0-999

offset speed pump; input only required on series pumping

applications. The flow rate of the constant speed pump is

deducted from the total system flow rate in order to pro-

vide end of curve protection for the variable speed pump
