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.

WARNING 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. Further more the

manufacturer recommends to test all the functions and

equipment connected to the MST, including the alarm

system and backup devices, after installation, after

change to the installation 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.

1. GENERAL

This document provides a description of the MST-5 control

panel. This document is organized as follows:

•Introduction

•Installation

•User’s Guide

•Appendix

1.1 DESCRIPTION

Congratulations on the purchase of your MST-5 Multistage

Thermostat. The MST product line provides you with full

control over temperature by heating or cooling, resulting in

a comfortable environment for your livestock.

The MST-5 provide the next features:

•Compatible with 2 speed motors

•Hi / Lo temperature recall

•Timer on first stage non active above the set point

•Timer for drip cool unit

•Automatic temperature ramping

•Adjustable differential for cooling and heating stages

The MST-5 provides microprocessor control over a five

stage output.

The first stage controls a single speed fan or the first

speed of a 2 speed motor. The stage also includes a

programmable duty cycle and adjustable timer setting.

The second stage provides control over a second single

speed fan or the second speed of a 2 speed fan.

The third stage provides control over a third fan or the first

speed of a 2 speed fan. The third stage can be used for a

drip cool unit with an adjustable timer setting.

The fourth stage controls a heater for cooler climates or a

fourth single speed fan or the second speed of a double

speed fan.

CHAPTER 1 - INTRODUCTION

MST 5

DESCRIPTION CONTINUED...

The fifth stage controls another heater for colder

climates or an other single speed fan.

The MST-5 provides you with full control over all five

stages via the use of an easy to follow display panel. All

programmable features can be customized to meet

your requirements. The MST-5 keeps you constantly

informed by displaying the status of all of its outputs as

well as the ambient temperature.

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 MST

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 MST-5 provides an constant automatic

temperature reduction (ramping) feature for your

maturing livestock. A built in low temperature safety

factor prevents temperatures from reaching dangerous

limits.

With MST-5 controlling 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 MST-5 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 the room.

RAMPING

An automatic daily reduction in the main set point and

all temperature settings relative to this.

DIFFERENTIAL

ON/OFF (relay). Range of temperature where two

conditions are possible. The output depends on

whether the temperature was increasing or decreasing

when it enters that range. The differential helps to avoid

frequent starts and stops of the actuator when

temperature is close to the relative set point.

DRIP COOL

Cooling system using evaporation to cool down

livestock.

Chapter 2 describes the installation of the MST-5 control.

2.1 UNPACKING

Unpack the MST-5 and inspect contents for damage.

Should the contents appear to be damaged, contact your

local distributor to return the material.

The package should contain the following standard items:

•1 MST-5 control

•1 installed temperature probe (model number 2004-1K)

•1 User’s manual

The following optional items may be included:

•3 additional temperature probes for temperature

averaging.

2.2 MOUNTING

The manufacturer recommends to closely observe the

following installation procedure, and that all work be

performed by a certified electrician. Failure to do so may

void the warranty!

CHAPTER 2 - INSTALLATION

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

unit in a hallway.

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

cable entry holes facing down.

The MST-5 will operate in a temperature range of 32°F to

120 °F (0 °C to 50 °C).

The enclosure is watertight, but it is not splash proof or

immersion proof. DO NOT WATER the control. Cover the

control carefully with plastic when you are cleaning the

room.

It is prohibited to use overhead cables outside the

building.

MST 5

Use a screwdriver to remove the faceplate and the plate

of the power compartment.

Install mounting screw on wall and hang the unit in place

by sliding the rear mounting hole of the MST-5 over the

screw.

Use two more screws to secure the MST-5 in place using

the bottom mounting hole.

2.3 SWITCH SETTINGS

The MST-5 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 MST- 5 for 115 VAC or

230 VAC line voltage.

Refer to Figures 1, and 2.

2.3.2 - Software Settings Switch

This switch is located at the rear of the MST-5 faceplate

and adjusts the following options.

Switch 1 Selects between a Fahrenheit or Celsius

display on the front panel.

Switch 2 Locks/unlocks user settings. All settings

except for main set point, record low, and

record high temperature are locked while this

switch is off.

Mounting hardware is not shipped with the unit.
