ECS 2M
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. Furthermore the
manufacturer recommends to test all the functions and
equipment connected to the ECS, including the alarm
system and backup devices, after installation, after
modifications, and once a 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-2M
control panel. It is organized as follows:
•Introduction
•Installation
•User’s Guide
•Appendix
1.1 DESCRIPTION
Congratulations on the purchase of your ECS-2M
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:
•Compatible with DIP-1.
•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 preventing motor damage.
The ECS-2M provides microprocessor control over a
two 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 air flow.

ECS 2M
DESCRIPTION CONTINUED...
The second stage controls either a heater for colder climates,
or a second fan where further cooling is required.
The ECS-2M provides you with full control of two stages via
the use of an easy to follow display panel. All programmable
features can be customized to meet your requirements. The
ECS-2M 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-2M 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 series 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 or not the ECS-2M is powered.
The ECS-2M 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 the ECS-2M in control of your climate, you are assured
of optimal living conditions for your livestock.

MAIN SET POINT
The desired room temperature. Other temperature
settings on the ECS-2M 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 of 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.
HYSTERESIS
Range of temperature where two conditions are possible.
The output depends on whether the temperature was
increasing or decreasing when it enters that range.

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

ECS 2M
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-2 M in place using the bottom mounting holes.
2.3 SWITCH SETTINGS
The ECS-2M 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.
To limit the unit’s exposure to noxious gases install it in
a hallway.
Make sure the unit is mounted right side up, with the
cable entry holes facing down.
The ECS-2M will operate in a temperature range of 32°F -
120 °F (0 °C - 50 °C).
* It is prohibited to use overhead cables outside the building.
Mounting hardware is not included with the unit.
