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.

WARNINGS 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. Furthermore the

manufacturer recommends to test all the functions and

equipment connected to the ECS, including the alarm

system and backup devices, after installation, after

modifications, and 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-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 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 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.

MAIN SET POINT

The desired room temperature. Other temperature

settings on the ECS-2M 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.

ROOM TEMPERATURE

The actual temperature of a closed area.

ROOM HUMIDITY

The actual humidity level of a closed area.

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.

HYSTERESIS

Range of temperature where two conditions are possible.

The output depends on whether the temperature was

increasing or decreasing when it enters that range.

Chapter 2 describes the installation of the ECS-2M control

panel.

2.1 UNPACKING

Unpack the ECS-2M and inspect contents for damage.

Should the contents appear to be damaged, contact your

local distributor for material return procedures.

The package should contain the following standard items:

•1 ECS-2M control .

•1 Installed temperature probe (model number 2004-

1K).

•2 Cable fasteners or fuses.

•1 User manual.

The following optional items may be added:

•3 additional temperature probes for temperature

averaging,

•1 humidity probe. The ECS-2M requires the RHT-1

humidity probe for maximum accuracy of monitoring

and control of humidity levels.

The manufacturer recommends that the following

installation instructions be adhered to as closely as

possible, and all work be performed by a certified

electrician. Failure to do so may void the warranty!

ECS 2M

2.2 MOUNTING

Use a screwdriver to remove the faceplate and the plate

on the power compartment.

Once both faceplates are off, install the mounting screw on the

wall and install the unit on it. Use two more screws to secure

the ECS-2 M in place using the bottom mounting holes.

2.3 SWITCH SETTINGS

The ECS-2M 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.

Refer to Figures 1, 2, and 3.

To limit the unit’s exposure to noxious gases install it in

a hallway.

Make sure the unit is mounted right side up, with the

cable entry holes facing down.

The ECS-2M 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 included with the unit.
