Although the manufacturer has made every effort
to ensure the accuracy of the information
contained herein, this document is subject to
change without notice due to ongoing product
development.
WARNINGS AND PRECAUTIONS
Equipment, probe failure, blown fuses and/or
tripped breakers may prove harmful to the
contents of the building. Therefore it is strongly
recommended to install backup devices and alarm
or warning devices. Spare equipment should also
be available at the owner’s site. Equipment
manufactured by the manufacturer is protected
against normal line surges. High surges caused by
thunder storms or power supply equipment may
damage this equipment. For added security
against line voltage surges it is recommended that
surge and noise suppression devices be installed
at the electrical distribution panel. Use of shielded
cable for probes is recommended for protection
against lightning. These devices are available from
most electrical supply distributors.
RECOMMENDATIONS
The manufacturer recommends that all installation
procedures described herein be performed by a
qualified electrician or installation technician.
Further more the manufacturer recommends to
test all the functions and equipment connected to
the ECS, including the alarm system and backup
devices, after installation, after changes to the
installation and every month after that.
Fuse verification and replacement, as well as the
proper setting of control values shall be the
responsibility of the owner of this equipment.

1. GENERAL
This document provides a description of the ECS-3M
control panel. It is organized as follows:
•Introduction
•Installation
•User’s Guide
•Appendix
1.1 DESCRIPTION
Congratulations on the purchase of your ECS-3M
environmental control system. The ECS-M product line
provides you with full control over temperature, humidity,
air flow, and heat, resulting in a comfortable environment
for your livestock.
The ECS-M product line offers a number of added features
over existing ECS controls, such as:
•Compatibility with DIP-1 control.
•Hi/Lo temperature indication.
•Automatic temperature reduction (ramping).
•Adaptable variable speed outputs for a wide selection
of fan model types.
•Humidity probe.
•Full torque fan start to prevent motor damage.
The ECS-3M provides microprocessor control over a three
stage output.
The first stage controls a variable speed fan which can
operate at a continuous low speed to ensure good quality
of air when room temperature is below the main set point.
In addition, the first stage may be programmed to cycle
ON and OFF. When room temperature rises above the
main set point, the fan accelerates to increase the airflow.
CHAPTER 1 - INTRODUCTION

ECS-3M
DESCRIPTION CONTINUED...
The second stage provides control over a second variable
speed fan to help the first fan when higher room temperatures
require increased airflow. This second stage is also fully
programmable for settings, such as minimum speed, relative
set point, etc.
The third stage controls either a heater for colder climates, or
a third fan where additional cooling is required.
The ECS-3M provides you with full control over all three
stages via the use of an easy to follow display panel. All
programmable features can be customized to meet your
requirements. The ECS-3M keeps you constantly informed by
displaying the status of all of its outputs as well as the room
temperature. With an optional humidity probe, the ECS-3M
displays current humidity levels.
Safety of livestock is ensured by the continuous control of
climate and timely alarm notification, should environmental
conditions exceed alarm set points. Further security may be
obtained by connecting all ECS controls in a network
configuration to a computer via the use of an optional RCM-
40 remote monitoring unit . This provides remote control
monitoring of each room. All control panel variable outputs
are fused, and all programmable settings are maintained,
whether the ECS-3M is powered or not.
The ECS-3M provides an automatic constant temperature
reduction (ramping) feature for your maturing livestock. A
built-in low temperature safety factor prevents temperatures
from reaching dangerous limits.
With an ECS-3M in control of your climate, you are assured of
optimal living conditions for your livestock.

DEFINITION OF TERMS
DEFINITION OF TERMS
MAIN SET POINT
The desired room temperature. Other temperature
settings on the ECS-3M are relative to the main set
point temperature.
RELATIVE TEMPERATURE
A value added to, or subtracted from the main set
point, which results in a new temperature at which a
desired action starts or stops.
ROOM TEMPERATURE
The actual temperature in a closed area.
ROOM HUMIDITY
The actual humidity level of a closed area.
MINIMUM FAN SPEED
The desired minimum speed for variable speed fans.
RAMPING
An automatic daily reduction in the main set point and
all temperature settings relative to this.
DIFFERENTIAL
ON/OFF (relay). Range of temperature where two
conditions are possible. The output depends on
whether the temperature was increasing or decreasing
when it enters that range.
VARIABLE. (Bandwidth) Temperature range where a
variable fan speed fan accelerates, as the
temperature increases. Minimum value at relative set
point and 100% at relative set point + Bandwidth.

CHAPTER 2 - INSTALLATION
Chapter 2 describes the installation of the ECS-3M
control panel.
2.1 UNPACKING
Unpack the ECS-3M and inspect contents for damage.
Should the contents appear to be damaged, contact
your local distributor for return procedures.
The package should contain the following standard
items:
•1 ECS-3M control.
•1 installed temperature probe (model number 2004-
1K).
•3 cable fasteners or fuses.
•1 Instruction manual.
The following optional items may be added:
•3 additional temperature probes for temperature
averaging,
•1 humidity probe. The ECS-3M requires the RHT-1
humidity probe for maximum accuracy of monitoring
and control of humidity levels.
The manufacturer recommends that the following
instructions be adhered to as closely as possible,
and that all work be performed by a certified
electrician. Failure to do so may void the warranty!

2.2 MOUNTING
Use a screwdriver to remove the faceplate and the plate
on the power compartment.
Once both faceplates are off, install the mounting screw
on the wall and install the unit on it. Use two more screws
to secure the ECS-3M in place using the bottom mounting
holes.
2.3 SWITCH SETTINGS
The ECS-3M is configured for a variety of options via two
switches as follows:
2.3.1 - Line Voltage Selector Switch
This switch is located on the surface of the main (bottom)
board and adapts the control panel for 115 VAC or 230
VAC line voltage.
Refer to Figures 1, 2, and 3.
Mounting hardware is not shipped with the unit.
230V
115V
To limit the unit’s exposure to noxious gases, install the
unit in a hallway.
Make sure the unit is mounted right side up with the
cable entry holes facing down.
The ECS-3M operates in a temperature range of 32°F -
120 °F (0 °C - 50 °C).
The enclosure is watertight, it is not splash proof or
immersion proof. DO NOT WATER the control. Cover it
carefully with plastic when cleaning the room.
* It is prohibited to use overhead cables outside the building.
