MICRO CONTROL SYSTEMS MCS-THERMOSTAT Micro Control System

MCS Thermostat’s Interface

The MCS-THERMOSTAT’S interface allows the viewing of 17 different parameters and has the ability to adjust 9 settings, including cooling & heating set points, operational schedules, holiday schedules, calibration and password protection.

The primary means of cycling through the thermostat’s options, menus, and settings- press the up button or down buttons to cycle thru the options.

Thermostat’s Display (Display Test)

The LCD screen displays seven icons reporting operational mode, current status and alarms.

Installation

The MCS-THERMOSTAT is powered by a +5vdc supply from an MCS controller via a two wire connection that can be wired with the communication network cabling. Improper wiring or installation may damage the thermostat. Wiring must conform to local and national electrical codes.

WARNING!
Before installing the thermostat, turn off all power to the unit. There may be more than one power disconnect. Electrical shock can cause personal injury or death.

NOTE: DO NOT INSTALL THE THERMOSTAT WHERE IT MAY BE AFFECTED BY AIR FROM NEARBY DUCT WORK, ELECTRONIC EQUIPMENT, ETC.

REQUIRED FOR INSTALLATION

• An MCS-THERMOSTAT with a +5 volt power supply
• 1/4” Phillips screwdriver
• 5/64” flathead screwdriver
• 2 ½ pan machine screws (included)
• 1 Wire cutter/stripper
• 4 Wire 22 to 20 awg Shielded Cable
• J-Box (USA or International)

MOUNTING LOCATION

• Install the MCS-THERMOSTAT on an interior wall. Exterior walls that are poorly insulated can affect the Thermostat temperature and humidity readings and may lead to wasted energy.
• Install the MCS-THERMOSTAT away from drafts, direct sunlight or anything that would cause the temperature to be artificially high or low.
• Install the MCS-THERMOSTAT so that it’s not blocked by doors or other obstructions.
• The Thermostat should be mounted approximately 5’ (1.5m) above the floor.

WIRING AND DISTANCE

Use 4 wire 22 to 20 awg Shielded Cable for installation. The MCS-THERMOSTAT can be installed up to 1000 feet from the MCS CONTROLLER.

Installation Mounting

UTILIZING J-BOX

MCS recommends you install the MCS-THERMOSTAT utilizing a J-Box. Prior to installing the MCS-THERMOSTAT punch out the corresponding mounting holes on the MCS-THERMOSTAT housing based on the J-box you are utilizing.

PUNCTURE SMALL HOLE

Puncture a small hole in the grommet on the back side of the thermostat. You want the wires to be tight so no air passes through affecting the thermostat’s reading.

OUTPUT WIRES

Push the output wires from the MCS Controller through the rear hole of the

• MCS-THERMOSTAT’S mounting plate. It may be good practice to wait until the wires are in position to be attached to the
• MCS-THERMOSTAT before they are stripped or cut with a tool.

The user will be able to see all functions of the thermostat if the controller’s configuration file is setup to allow this. Some functions of the thermostat may be turned off in the configuration file to help protect unauthorized users from making changes.
Authorization Levels- The MicroMag and MAGNUM allow several levels of password protection that have been setup in your thermostat – ‘Service’, ‘Supvsr’ (Supervisor), and ‘Factory.’ The Installer can setup the Authorization Levels at this time. This will allow a user with the correct password to make changes. OPERATION OF THE THERMOSTAT CAN BE CONTROLLED BY THESE LEVELS OF AUTHORIZATION. SEE EXAMPLE NEXT PAGE

UNIT = DEGREES
Hit ‘ENTER’ -Allows the user to change between Celsius and Fahrenheit. Directions: Use the Up/Down arrows to move between Celsius and Fahrenheit. Press ‘Enter’ to select the desired unit degrees and the display will confirm the change.

MODIFY SCHEDULES
Unlike Thermostats that are used at home and in an some office buildings, the MCS Thermostat ‘SCHEDULES’ control the run/stop of the controller’s cool target and heat target setting only. Think of the Thermostat ‘SCHEDULES’ as controlling whether a building or room  OCCUPLIED or ‘UNOCCUPLIED’. We can still allow the building or room to be cooled or heated, but with target setting, we can lower (or raise) the temperature depending on whether the building or room is ‘OCCUPLIED’.
For example if you set ‘SCHEDULE ONE’ to start at 8:00am the thermostat will start either the cooling process or heating process of the unit based on the cooling/heating targets that you have setup in the Thermostat or configuration of the controller. Setting ‘SCHEDULE ONE’ to end at 17:00 (5:00pm) the Thermostat can change how the building or room is heated or cooled. The advantage of the MCS Thermostat is that you can override the target settings of the UNIT’S heating, cooling and humidity from the thermostat without the going to the actual unit. See an example of setting up the schedules and holidays on the next pages.

SETTING EACH DAY OF THE WEEK

Schedule setting start with Sunday as the first day.

1. Press Menu button to ‘CONFIG MENU’, press ‘ENTER’
2. Use  ‘DOWN’ to ‘MODIFY SCHEDULES’, press  ‘ENTER’
3. The first schedule day will appear on the screen ‘SUN Schedule 1 start’ press  ‘ENTER’ to accept this day.
4. The next screen display will show the Hour ‘BLINKING’ – enter the hour, press  ‘ENTER’ to move to the minutes. After you set the minutes, press ‘ENTER’ to accept, the following screen will appear ‘Prs Enter to continue’. The information will be sent to the controller.
5. Be sure to set the ‘START and ‘END TIMES’ for each day for ‘SCHEDULE 1’ and for ‘SCHEDULE 2’ before proceeding to the next day on the Thermostat.
6. IF YOU DO NOT SEE THE ‘HOUR BLINKING’ YOU FORGOT TO PRESS ENTER FOR THE NEXT SCHEDULE DAY.

Below is a screen shot from MCS-CONNECT showing what the schedule settings look like in the configuration setup. Basically this is what you are setting up when you are setting the ‘SCHEDULES and HOLIDAYS’ times in the Thermostat.

MODIFY HOLIDAYS

These settings allows the user to adjust the thermostat’s “START and END’ times for holidays that

have been setup in the configuration file or thru MCS-CONNECT. Press the Up/Down arrows and Enter buttons to make adjustments. See screen shot on previous page as an example.
