HVAC Forum Forum October October 2005 2005 II New Multi Pump Offer High Performance Setpoint Ramping On transition from any state into PID control, the reference is ramped from the current feedback level to the required setpoint This prevents an unwanted initial large error System Drained Pipe fill algorithm On initial start-up pipes may be empty Starting PID control under these conditions would result in the PID ramping up, due to a low feedback Pipe fill runs the system at a preset speed until a start pressure is reached and then transfers into PID control HVAC HVAC Forum Forum October

to switching off, the pressure is boosted up, to have more margin against “pressure leakage” Duty selection modes available, mono joker and auxiliary pumps permutation or mono joker and auxiliary pumps permutation with the limitation of the operating time Staging and de staging Reduced Undershoot Staging and de staging conditions can be based on speed, pressure, PID error or any combination of these A delay allows for further fine tuning During this operation, the speed of the variable speed pump is set to adjustable values This ensures smooth pick up and drop off for fixed speed pumps HVAC HVAC Forum Forum October October 2005 2005 II New Multi Pump Offer Standard no demand detection impossible Pump Compatibility Special Sleep Function for flat curve pumps H If pumps with a flat H-Q curve are used, it may be difficult to identify a no demand situation.This algorithm detects a no demand situation via the response to a step decrease in setpoint Pump priming Q Some pump systems require the main pump to be primed with fluid prior to starting to prevent them from running dry for too long HVAC HVAC Forum Forum October October 2005 2005 II New Multi Pump Offer Enhanced System
