1. GENERAL
This document provides you with the necessary
information to install and operate the CPS-3M. The
document is presented as follows:
•Introduction
•Installation
•User’s Guide
•Appendix
Congratulations on your purchase of a CPS-3M natural
ventilation system. With options such as motor activated
curtains and integrated heating units, this product is
designed to provide optimal temperature control in
ventilated buildings.
The CPS-3M controls natural ventilation, either
simultaneously on both sides with a single actuator, or
independantly on both sides with 2 actuators. Those
options can be selected from a dip switch, located behind
the electronic card, inside the faceplate.
Moreover, the CPS-3M is equiped with state of the art logic
for extra-accurate ventilation and heating control.
The present manual has been published in order to make
custom installation and control easier. Initially, the CPS-3M
was designed for 3-wire actuators. If, however, four-wire
actuators are used, external relays will have to be installed
according to the wiring diagram (fig. 5) on page 14. Before
choosing any type of relay, make sure to consult the
specifications table (p. 41) of this manual. It contains the
minimum load information for CPS-3M’s relays.

CHAPTER 3 - USER’S GUIDE
The CPS-3M’s faceplate shown above features a LED
status window and two control dials which are
usedrespectively to select a function and select a setting.
LED Status Window
The LED status window features a 3 digit LED readouts
display of temperature in Fahrenheit or Celsius, and
programmable settings.
In addition, the LED status window displays the operational
status of zone 1 and 2 via 2 LEDS per zone(see above
picture). When illuminated, each LED indicates that the
actuator motor is operating. A fifth LED is for the heating
unit and a sixth one is for the Hi / LO temperature alarms.
Control Dials
The center dial is the selector dial and is used to select one
of the CPS-3M’s 12 primary or 8 secondary functions. The
dial to the right of the selector dial is the adjustor dial and is
used to adjust the setting of each function or to enter
secondary mode.
The 12 primary functions are:
•1 Zone 2 room temperature
•2 Zone 2 temperature main set point
•3 Zone 2 actuator max run time

ZONE 2 ROOM TEMPERATURE
DISPLAY
This position displays the actual room
temperature (zone 2). When monitoring only 1
zone, the displays shows three horizontal bars
for this position.
Room temperature is displayed to the nearest
0.1 degree from a minimum display of 42.0°F
(5.5°C) to a maximum display of 111°F (44.0°C).
If temperature is lower than 42.0°F, Lo is
displayed. If temperature is higher than 111°F,

CPS-3M
ZONE 2 MAIN SET POINT TEMPERATURE
(MANUAL MODE)
The main set point establishes the target
temperature in the building. The main set point
temperature is adjusted in 0.5 degree increments
from a minimum setting of 42.0°F (5.5°C) to a
maximum setting of 111°F (44.0°C).
Adjusting the main set point temperature:
•rotate the selector dial to position (2),
•rotate the adjustor dial counterclockwise to
decrease the setting, and clockwise to increase
it.
The main set point temperature is displayed on the
CPS-3M.
Manual mode:
The actuator motor may be manually controlled by
adjusting the main set point to OPN or CLO,
thereby causing the air inlet to either remain fully
open or closed.
To open the air inlet:
•rotate the selector dial to position (2), then, the
adjustor dial counterclockwise to the minimum
setting, until the display shows OPN. At that
particular moment, the air inlet is opening.
To close the air inlet:
•rotate the selector dial to position (2), then, the
adjustor dial clockwise to the maximum setting,
until the display shows CLO. At that particular
moment, the air inlet is closing.
www.monitrol.com

Page 19
ZONE 2 MAXIMUM RUN TIME
The air inlet timer establishes the maximum period
of running time for the actuator’s motor, which
shouldn’t count for more than 25% of the inlet’s
total movement, according to the actuator’s
manufacturer.
The timer is adjusted in 1 second increments from
a minimum setting of 1 second to a maximum
setting of 4 minutes.
Adjusting the inlet timer:
•rotate the selector dial to position (3),
•rotate the adjustor dial counterclockwise to
decrease the setting, and clockwise to increase
it.
CHAPTER 3 - USER’S GUIDE
The CPS-3M automatically calculates a run time
according to temperature variations and the difference
between room temperature and the main set point.
Example:
The timer is set to 30 seconds. When the control
determines that the air inlet must open, the timer’s delay
set by primary function (3) must run until the end. Then
the actuator motor will operate for 30 seconds before
stopping.
