CONFIGURATION
8.D.6.a Variable Speed Pump Control
Variable speed pump control and the Vari-Prime Screen allows the adjustment of the
following parameters:
• On Delay – Upon a call for heat, once the unit ignites, this is the amount of time the unit will wait prior to
modulating the pump speed.
• Proportional Gain – This value is the corrective action that is proportional to the error (Set Point – Control
Temperature).
• Integral Time – This value is applied to the sum of the error over a period of time.
• Derivative Time – This value is applied to the rate of change of the error.
• Minimum Speed – This is the minimum speed to which the Vari-Prime will control the pump.
• Maximum Speed – The is the maximum speed to which the Vari-Prime will control the pump.
•ODelay– Once the heat demand is satised, Vari-Prime will control to the maximum pump speed until the O
Delay time expires.
• Delta T – Vari-Prime will control the pump to maintain this delta T (temperature rise) across the unit.
Note: Variable Speed Pump Control applies only to Boilers.
