Series P215PR/RM
Direct- and Remote-Mount Pressure-Actuated Condenser
Fan Speed Controllers for Single-Phase Motors
Introduction
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 Figure 1: P215PR Direct-Mount Pressure-
refrigerant system. The controller varies the supply Actuated Condenser Fan Speed Controller
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.

IMPORTANT: Use this Series P215PR/RM
Pressure Actuated Condenser Fan Speed
Controller only as an operating control. Where
failure or malfunction of the P215PR/RM could lead
to personal injury or property damage to the
controlled equipment or other property, additional
precautions must be designed into the control
system. Incorporate and maintain other devices,
such as supervisory or alarm systems or safety or
limit controls, intended to warn of or protect against
failure or malfunction of the P215PR/RM
Controller.

Electro-Magnetic Capability
The controller includes a built-in suppression filter
and meets required (EC) directives. However, when
two or more Electro-Magnetic-Compatibility (EMC)
compliant components are combined, the entire
system may not be compliant. It is the end user’s
