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 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 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.

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 fig. 7).
BACKUP THERMOSTAT. If the Varifan control fails, 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
adjustment and should be set at the same temperature as
the alarm, i.e. approximately 5ºF above the fan relative set
point.
BACKUP POWER SOURCE. The DPDT relay connects
to source 1 in normal operation but will switch to source 2
if source 1 is off. The relay shall be chosen to support the
load connect to it.
ALARM CIRCUIT. In regular circumstances, the alarm
circuit of the Varifan Control is a short circuit. But if the
Varifan control is defective or if there is no power applied
to it, then the alarm circuit of the control will be an open
circuit.

REL. HUMIDITY SP
If the ECS is equipped with an optional humidity
sensor, this setting regulates the humidity level of the
room. The humidity setting affects the operation of Fan
1 only. When the humidity level of the room exceeds
the relative humidity setting, Fan 1 runs at a new
minimum speed set by secondary function (3). The fan
operates at this speed as long as room temperature is
below the main set point.
When the temperature of the room is greater than the
main set point temperature the fan speed increases
until the maximum speed for the fan is reached. 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 Adjustor dial back and forth to enter
secondary function mode,
•rotate the Selector dial to position (1),
•rotate the Adjustor dial counterclockwise to decrease
the humidity setting, clockwise to increase it.
The humidity setting is displayed on the ECS.

FAN 1 MIN. HUM.
This function establishes the minimum speed
of Fan 1 when the relative humidity level of the
room exceeds the relative humidity setting.
The speed setting for humidity must be
configured higher than the speed setting for
temperature. This value is entered as a
percentage of maximum speed.
The Fan 1 minimum speed is adjusted in 2%
increments from a minimum setting of 12% to
a maximum setting of 100%.
Adjusting Fan 1 minimum speed for
humidity:
• rotate the Selector dial to position (12),
• rapidly rotate the Adjustor dial back and
forth to enter secondary function mode,
• rotate the Selector dial to position (3),
• rotate the Adjustor dial counterclockwise to

FAN 1 PERIOD
This function sets the maximum speed of Fan 1 when
room temperature is higher the main set point. This
value is entered as a percentage of maximum speed.
Fan 1 maximum speed is adjusted in 2% increments
from a minimum of 60% to a maximum of 100%.
Adjusting the maximum speed of Fan 1:
• rotate the Selector dial to position (12),
• rapidly rotate the Adjustor dial back and forth to enter
secondary function mode,
• rotate the Selector dial to position (4),
• rotate the Adjustor dial counterclockwise to decrease
the maximum speed, clockwise to increase it.
The Fan 1 period is displayed on the ECS.

HEAT/FAN 2 DIFF.
In order to minimize erratic behavior of Heater/Fan 2
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.
The temperature difference
thresholds is the differential.
between
the
two
The differential is adjusted in 0.5 degree increments
from a minimum setting of 1°F (0.5°C) to a maximum
setting of 6°F (3°C) degrees.
Adjusting the differential setting:
• rotate the Selector dial to position (12),
• rapidly rotate the Adjustor dial back and forth to enter
secondary function mode,
• rotate the Selector dial to position (8),
• rotate the Adjustor dial counterclockwise to decrease
the differential setting, clockwise to increase it.

MINIMUM RAMPING
Minimum ramping is the lowest value that the ramping
function can adjust the main set point to. This is a
security feature.
The minimum ramping setting is adjusted in 0.5 degree
increments from a minimum setting of 13.5°F (-9.5°C)
to a maximum setting of 105.0°F (41.0°C).
Adjusting the minimum ramping setting:
• rotate the Selector dial to position (12),
• rapidly rotate the Adjustor dial back and forth to
enter secondary function mode,
• rotate the Selector dial to position (9),
• rotate the Adjustor dial counterclockwise to decrease
the minimum ramping setting, clockwise to increase
it.
The minimum ramping setting is displayed on the ECS.
NOTE: When the main set point

LO TEMP. ALARM
This function establishes the temperature difference
below the main set point that the room can reach
before a low temperature alarm is signalled. When a
low temperature alarm occurs, an alarm contact is
activated and the alarm LED lights up on the front
panel.
The low temperature alarm is adjusted in 0.5 degree
increments from a minimum setting of -32.0°F (-18.0°C)
to a maximum setting of 0.0°F (0.0°C)
Adjusting the low temperature alarm setting:
• rotate the Selector dial to position (12),
• rapidly rotate the Adjustor dial back and forth to enter
secondary function mode,
• rotate the Selector dial to position (10),
• rotate the Adjustor dial counterclockwise to decrease
the setting, clockwise to increase it.
The low temperature alarm setting is displayed on the
ECS.

HI TEMP ALARM
This function establishes the temperature difference
above the main set point that the room can reach
before a high temperature alarm is signalled. When a
high temperature alarm occurs an alarm contact is activated and the alarm LED lights up on the front panel.
The high temperature alarm is adjusted in 0.5 degree
increments from a minimum setting of 0°F (0°C) to a
maximum setting of 32.0°F (18.0°C)
Adjusting the high temperature alarm:
• rotate the Selector dial to position (12),
• rapidly rotate the Adjustor dial back and forth to enter
secondary function mode,
• rotate the Selector dial to position (11),
• rotate the Adjustor dial counterclockwise to decrease
the setting, clockwise to increase it.

RELATIVE HUMIDITY
This function displays the relative humidity of the room.
Relative humidity is displayed in 1% increments from a
minimum display of 30% to a maximum display of
90%. If a humidity level lower than 30% is monitored,
F2 is displayed. On the other hand, if a humidity level
higher than 90% is monitored, Hi is displayed.
Displaying the relative humidity level:
• rotate the Selector dial to position (12),
• rapidly rotate the Adjustor dial back and forth to
enter secondary function mode.
The humidity level is displayed on the ECS.
