Appendix
1.1 DESCRIPTION
Congratulations on the purchase of your ECS 1M
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 EPM-10 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 1M provides microprocessor control over a
single stage output.
This 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.

ECS 1M
DESCRIPTION CONTINUED...
The ECS 1M provides you with full control over one
stage via the use of an easy to follow display panel. All
programmable features can be customized to meet
your requirements. The ECS 1M 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 1M 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. The control panel variable
output is fused, and all programmable settings are
maintained whether or not the ECS 1M is powered.
The ECS 1M provides an automatic constant
temperature reduction (ramping) feature for your
maturing livestock. A built in low temperature safety
factor prevents temperatures reaching dangerous
limits.
The ECS 1M can control an EPM-10. This control is
designed to position an air inlet baffle board or air inlet
curtain without the use of a feedback potentiometer or
0 - 10 volts analog signal. The EPM-10 provides an
automated positioning of your air inlet according to
the signal sent by the ECS 1M, or alternatively by
manual position knob control on the EPM-10 .
With ECS 1M in control of your climate, you are
assured of optimal living conditions for your livestock.

VARIFAN 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.
6).
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
its adjustment and it 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 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 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.
