General

The Series P215PR/RM direct-mount and remote- mount pressure-actuated condenser fan speed controllers are designed for speed variation of single-phase motors. Head pressure control of a refrigeration system, through speed variation of the fan on an air-cooled condenser, results in optimum performance throughout the year. Once the output drops below 30%, the fan is cut off. The Series P215PR/RM controllers are designed for non-corrosive refrigerant systems. See Table 1 for a list of features and benefits.

A pressure-actuated control provides the most direct and fastest response to pressure variations in the refrigerant system. The controller varies the supply voltage to the motor from 30% to at least 95% over the proportional band using the phase-cutting principle. This principle provides speed variation of a permanent split capacitor or shaded pole motors that do not draw more than 4 A (RMS) full-load current. The motor manufacturer should have approved the product for this speed control principle.  

We recommend confirming with the electric motor manufacturer that the motor can be used with a controller, using the phase-cutting principle for speed variation. You can also provide a copy of this product data sheet to the motor manufacturer or supplier for review.
