Page 6: Introduction
The manual contains a complete description of all the functions of the climate computer and the structure of the manual follows the menu structure of the computer. As the MC 135CT software is modular software, this manual may include sections that are irrelevant to the setup of your computer. -

Page 12: Connecting Or Disconnecting Heat Supply
The house ventilation consists of an air intake and an air outlet. Apart from supplying fresh air to the house, ventilation is to remove humidity and excess heat, if any. MC 135CT continuously adjusts the ventilation according to a calculation of the current ventilation requirement. Thus, the computer will increase or limit ventilation according to whether the inside temperature and air humidity are too high or too low. -
Page 13: Maximum Ventilation
MC 135CT calculates the necessary minimum ventilation according to the animals’ need for fresh air. This varies depending on race and weight. You can find the correct figure in the technical literature or ask your consultant if in doubt. -

The inside temperature where the Tunnel ventilation is to stop (this function is not Stop temperature active when MC 135CT is set up to work in pure Tunnel mode). -
Page 15: Pressure Control
By means of a pressure sensor, the MC 135CT computer can control the pressure level in the house. On the basis of the sensor measurements, MC 135CT controls the opening of the flaps and in this way it maintains the required pressure level in the house,... -
Page 16: Humidity
Water consumption MC 135CT sums up the water consumption in litres to provide an overall view. In order to expose sudden changes, the water consumption is also summed up in per cent. Under normal conditions, the percentages will rise by a few per cent per day as the age of the animals progresses. -
Page 17: Management

On the other hand, if you want the system to close when batch status is empty house, you should reset the settings of the in-between function empty house. In batch status, MC 135CT will also reset all changes of curves, which you may have made in the previous batch course. -
Page 19: In-Between Function
The in-between functions are partly designed for facilitating your cleaning activities when the house is depopulated, partly to ensure the air change and temperature in the empty house. MC 135CT Climate Computer can only activate the in-between functions when is set Batch status (in the house data menu under management). -

Page 22: Active Alarms
5.3 Alarm Limits MC 135CT Climate Computer contains a number of alarms, which the computer will activate if a technical error occurs or the alarm limits are exceeded. A few of the alarms are always connected, e.g. -
Page 23: Alarms Not Maintained
When the outside temperature increases, the alarm limit will also increase. Thus, it will postpone the time when the high temperature alarm is activated. MC 135CT Climate Computer only activates the alarm if the inside temperature also exceeds the high temperature alarm. -
Page 24: Sensor Alarms
Alarm for Error in Humidity Sensor MC 135CT Climate Computer activates an alarm when the humidity sensor is disconnected or the air humidity is lower than humidity setpoint. The alarm limit is factory preset at such a low level (5 %) that the alarm is only triggered by actual sensor errors. -
Page 25: Emergency Opening
Emergency Opening Emergency opening is a standard function in the MC 135CT Climate Computer. As long as there is power, the computer will open the ventilation system 100 % in case of a relevant alarm - even if it is cold outside. -

Page 30: Maintenance Instructions
You should test the alarm system every week. 7 Cleaning Clean the MC 135CT with a damp cloth without using solvents. Do not expose the computer to water or cleaning with a high-pressure cleaner. Like all types of electronics, it prolongs the life of the MC 135CT to be continuously connected to power as this keeps it dry and free from possible condensation. - Page 32 BIG DUTCHMAN International GmbH • Calveslage • Auf der Lage 2 • 49377 Vechta Tel. 04447/801-0 • Fax 04447/801-237...
