ECS 5M
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.
WARNING 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
change to the installation and at least 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 5M
control panel. This document is organized as follows:
•Introduction
•Installation
•User’s Guide
•Appendix
1.1 DESCRIPTION
Congratulations on the purchase of your ECS 5M
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 5M offer these features:
•Compatible with IPM-1 and 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 5M provides microprocessor control over a five
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 the room temperature is below the main set
point. In addition, the first stage may be programmed to
cycle on and off. When the room temperature rises above
the main set point, the fan accelerates to increase the air
flow.
CHAPTER 1 - INTRODUCTION

ECS 5M
DESCRIPTION CONTINUED...
The second stage provides control over a second variable speed
fan. The second stage is also fully programmable for settings such
as minimum speed, relative set point etc.
The third stage controls a third single speed fan to aid the second
fan for increased air flow.
The fourth stage controls either a fourth single fan or a drip cool
unit with programmable duty cycle and adjustable timer setting.
The fifth stage controls either a heater for colder climates, or a
fifth single speed fan where even cooling is required.
The ECS 5M provides you with full control over all five stages via
the use of an easy to follow display panel. All programmable
features can be customized to meet your requirements. The ECS
5M keeps you constantly informed by displaying the status of all of
its outputs as well as the ambient temperature. With an optional
humidity probe, the ECS 5M 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
ECS variable outputs are fused, and all programmable settings
are maintained whether or not the ECS 5M is powered.
The ECS 5M provides an automatic constant temperature
reduction (ramping) feature for your maturing livestock. A built in
low temperature safety factor prevents temperatures reaching
dangerous limits.
With ECS 5M in control of your climate, you are assured of
optimal living conditions for your livestock.

Page 7
MAIN SET POINT
The desired room temperature. Other temperature
settings on the ECS 5M 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.
AMBIENT TEMPERATURE
The actual temperature of the room.
AMBIENT HUMIDITY
The actual humidity level of the room.
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
increase. Minimum value at relative set point and 100% at
relative set point + Bandwidth.
DRIP COOL
A device used to cool down livestock.

Chapter 2 describes the installation of the ECS 5M control.
2.1 UNPACKING
Unpack the ECS 5M from its box and inspect contents for
damage. Should the contents appear to be damaged,
contact your local distributor for return material procedures.
The package should contain the following standard items:
•1 ECS 5M control .
•1 installed temperature probe (model number 2004-
1K).
•5 cable fasteners or fuses.
•1 User’s manual.
The following optional items may be included:
•3 additional temperature probes for temperature
averaging,
•1 humidity probe. The ECS 5M requires the RHT-1
humidity probe for maximum accuracy of monitoring
and control of humidity levels.
The manufacturer recommends that the installation
instructions which follow be adhered to as closely as
possible, and all work be performed by a certified
electrician. Failure to do so may void the warranty!
CHAPTER 2 - INSTALLATION

ECS 5M
2.2 MOUNTING
Mont the control panel to the wall using the mounting
holes located on the flange of the control housing.
Once the ECS 5M is in place, use a screwdriver to
remove the six screws holding the faceplate to the
housing.
2.3 SWITCH SETTINGS
The ECS 5M 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.
To limit the unit’s exposure to noxious gases install the
unit in a hallway.
Make certain that the unit is mounted right side up with
the cable entry holes facing down.
The ECS 5M 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 shipped with the unit.
