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.
Page 5
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 RCM40 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 5º C 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.

SECONDARY FUNCTIONS
RELATIVE HUMIDITY SET POINT
RH
This setting regulates room humidity only
when a humidity sensor is connected to the
ECS. The humidity setting affects Fan 1 only.
When humidity in the room exceeds the
relative humidity set point, Fan 1 minimum
speed increases gradually and proportionally.
If relative humidity rises in the 10% range
above the humidity set point, minimum speed
also increases proportionally up to the value
set by secondary function (3). The humidity
level is adjusted in 1% increments from a
minimum setting of 30% to a maximum setting
of 80%.
Adjusting the relative humidity level:
•rotate the selector dial to position (12),
•rapidly rotate the adjuster dial back and forth
to enter secondary function mode,
•rotate the selector dial to position (1),
•rotate the adjuster dial counterclockwise to
decrease the humidity set point, clockwise to
increase it.

This function establishes the minimum speed
of Fan 1 when the relative humidity level of
the room exceeds the relative humidity set
point. The speed setting for humidity must be
set higher than the speed setting for
temperature. This value is entered as a
percentage of maximum speed.
Humidity
The Fan 1 minimum speed is adjusted in 2%
increments from a minimum setting of 12% to
a maximum setting of 100%.
Adjusting the Fan 1 minimum speed for
humidity:

Heater/Fan 3 when room temperature is
exactly at the relative set point, the
differential setting separates this ON/OFF
threshold into two: one ON threshold and
one OFF. This feature greatly reduces
equipment wear.
Diff
The temperature difference between the two
thresholds is the differential.
The differential is adjusted in 0.5 degree
