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.

RECOMMENDED CONTROL BACKUP
WARNING AND PRECAUTIONS
Equipment failure, blown fuses and/or tripped breakers
may prove harmful to the content of the building. It is
therefore strongly recommended to install backup devices
and alarm or warning devices (see example fig. 7).
BACKUP THERMOSTAT. If the control is defective, then
the thermostat will start the dedicated fan at full speed
when the temperature will reach the T15-WD set value.
Therefore, the T15-WD should be accessible for its
adjustment and it should be set at the same temperature
as the alarm, i.e. approximately 5ºC above the fan relative
set point.
BACKUP POWER SOURCE. The DPDT relay connects
to the source 1 in normal operation but will switch to the
source 2 if source 1 is off. The relay shall be chosen to
support the load connect to it.
ALARM CIRCUIT. In normal operation, the alarm circuit of
the Varifan control is a short circuit. But if the control is
defective or if there is no power applied to it, then the
alarm circuit of the control will be an open circuit.

LED status window and two control dials which are used
respectively to select a function and adjust a setting.
LED STATUS WINDOW
The LED status window features a 3 digit LED readout for
the display of temperature in Fahrenheit or Celsius,
humidity level, and programmable settings.
In addition, the LED status window displays the
operational status of Fans 1, 2, and Fan 3 or a heater via
four additional LEDS (shown above in LED window).
When ON, each LED indicates that its associated fan or
heater is operating. The fourth LED lights up to indicate a
low or high temperature alarm condition.
CONTROL DIALS
The center dial is the Selector dial and is used to select
one of the control panel’s 12 primary or 10 secondary
functions. The dial located to the right of the Selector dial
is the Adjuster dial and is used to enter secondary
function mode and to adjust the setting of each function.
