Methods as disclosed herein are generally configured to help determine a pressure differential (or pressure head) in a fluid circulation system of for example, a HVAC system, for controlling the fluid circulation system. The method may include obtaining a correlation between a fluid flow rate and a pressure differential in the fluid circulation system by varying an operation speed of the pump. The method may also include obtaining a desired fluid flow rate for matching a cooling capacity of the HVAC system and determining a pressure differential setpoint corresponding to the desired fluid flow rate based on the correlation between the fluid flow rate and the pressure differential. The methods can be executed by, for example, a controller of the HVAC system so as to eliminate the requirement of a user to set up the pressure differential.
