Page 5: Chapter 1 - Introduction
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. -
Page 6: Definition Of Terms
CPS-3M DEFINITION OF TERMS TEMPERATURE MAIN SET POINT The desired temperature in a room. ROOM TEMPERATURE The actual room temperature AIR INLET/ CURTAIN A device which regulates airflow into a building by controlling the opening or closing of an air passage. -
Page 7: Unpacking
Failure to do so may void the warranty! 2.1 UNPACKING Unpack the CPS-3M from its box and inspect contents for damage. Should the contents appear to be damaged, contact your local distributor to return the material . -
Page 8: Switch Settings
The CPS-3M is configured for a variety of options via the two following switches: 2.3.1 - Line Voltage Selector Switch This switch is located on the surface of the main (bottom) board and adapts the CPS-3M to 115 VAC or 230 VAC line voltage. 230V 115V See figure 1 2.3.2 - Software setting switch... -
Page 9: Connection Procedure
2.4.1 - Input power Use a screwdriver to remove cable knock-outs for the installation of cables on the CPS-3M. Do not power up the CPS-3M until all connections have been completed! 2.4.1.1 - 115 VAC Make sure that the line voltage selector switch is set to 115 VAC. -
Page 10: Temperature Probe
These cables can measure up to 500 feet (150 meters). Probes longer than 10 feet (3 meters) must be shielded with a #18AWG aluminum wire, or one bigger. The shield must be connected to the CPS-3M’s SHLD terminal. The connections for 2 temperature probes are illustrated in figure 2, whereas the connections for temperature averaging are illustrated in figure 3. -
Page 11: Alarm
Make the normally closed (NC) or normally open (NO) connections as indicated in figure 2. Momentary power interruptions may trigger false alarms! To avoid them, when the CPS-3M is connected to an alarm system, install a time delay relay between the CPS-3M and the alarm system. - Page 12 CPS-3M Figure 1 Wiring for 2 actuators and 1 heating unit WARNING!!!

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. - Page 16 (12) to any other secondary function. When secondary functions (2) through (11) are selected, the status window displays a blinking value along with a scrolling LED display. Selection of function (12) switches the CPS-3M back to primary mode. Page 16 www.monitrol.com...

Page 17: Zone 2 Room Temperature Display
If temperature is lower than 42.0°F, Lo is displayed. If temperature is higher than 111°F, Hi is displayed. Viewing the room temperature: • rotate the selector dial to position (1) The room temperature for zone 2 is displayed on the CPS-3M. Page 17 www.monitrol.com... -
Page 18: Zone 2 Main Set Point Temperature
CPS-3M ZONE 2 MAIN SET POINT TEMPERATURE (MANUAL MODE) main point establishes 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). -
Page 19: Zone 2 Maximum Run Time
• rotate the selector dial to position (3), • rotate the adjustor dial counterclockwise to decrease the setting, and clockwise to increase The CPS-3M automatically calculates a run time according to temperature variations and the difference between room temperature and the main set point. -
Page 20: Zone 2 Record High Temperature
Viewing the highest temperature recorded in zone 2: • rotate the selector dial to position (4) Clearing the high temperature value: • quickly rotate adjustor dial counterclockwise, then clockwise. CLr will be briefly displayed on the CPS-3M Page 20 www.monitrol.com... -
Page 21: Zone 2 Record Low Temperature
Lo is displayed. Viewing the lowest temperature recorded: • rotate the selector dial to position (5) Clearing the low temperature value: • Quickly rotate adjustor dial counterclockwise, then clockwise. CLr will be briefly displayed on the CPS-3M. Page 21 www.monitrol.com... -
Page 22: Heating Set Point
CPS-3M HEATING SET POINT The CPS-3M has an absolute heating set point; meaning that this function establishes the temperature at which heating goes ON. It stops, then starts again when temperature reaches the heating differential set by position (7). When 2 zones are selected, the temperature considered is the average temperature of the 2 zones. -
Page 23: Heating Differential
Adjusting the heating differential: • rotate the selector dial to position (7), • rotate the adjustor dial counterclockwise to decrease the differential, and clockwise to increase it. The differential is displayed on the CPS-3M. Page 23 www.monitrol.com... -
