Thomas climate controller

Thomas climate CL controller



Thomas Climate is a versatile climate and management computer. This computer is characterized by its ease of use. Icons on the large screen show the available functions. Thomas Climate controls and manages your animals’ living environment to ensure optimum results.

With the ThomApp, you can control one or more barn computers remotely with your smartphone or tablet. This gives you full control over all processes, anytime, anywhere.

It is possible to copy all the settings, simultaneously or separately, from one room to other rooms. With the curve settings, you can adjust the climate according to the age of your animals.


The ventilation is controlled by means of proportional and/or step ventilation. Up to 10 fan groups can be configured, including a maximum of 3 proportional groups.

In each room, the ratio between controlled and measured ventilation capacity is monitored. It is possible to set an upper and lower limit for this ratio. As soon as the ratio is no longer within the set limits, an alarm will be issued. With central ventilation, this also includes the ratios of the other rooms. This also prevents the deviating room from disrupting the ventilation of the other rooms.

Air Inlets

The air inlets can be controlled per room:

  • on temperature (max. 2 controls)
  • synchronous with the ventilation (max. 1 control)
  • on negative pressure (max. 1 control)


For each room 2 heating controls can be set; you can choose between an ON/OFF control or a proportional control. The set temperature of the heating control may be room temperature dependent, e.g. the set temperature of the piglet nest heating can be configured according to the room temperature. It is possible to regulate the heating as a 2nd temperature control, with its own temperature sensors.


Cooling takes place by means of an ON/OFF contact; optionally, it can operate by means of pulse/pause. It is possible to link the cooling to the RH level.

Easy Buttons

To override the lighting and/or to switch from one phase to another.

(LED) Lighting

The (LED) lighting can be controlled in two ways, with an ON/OFF control or a dimmable control. It is possible to override the lighting with the Easy Button.


You can use the Easy Button to switch between various preset phases. In this way, Thomas Climate ensures that the settings for the climate are perfectly matched to the room’s current phase at that moment. The phases to which the room can be set are: Production / Move out / Empty / Soaking / Cleaning / Drying and Warming up.


The humidifier is controlled by an ON/OFF contact, and is linked to the RH level.

RH/CO /NH level

The RH/CO2/NH3 level can be monitored using a sensor and, if necessary, Thomas Climate will adjust the ventilation accordingly.


Using a water counter, it is possible to record the water consumption. In addition, the water valve can, if desired, be controlled via a timer with a maximum of 24 set times.


Thomas Climate is equipped with one timer per room that can be set to a maximum of 24 switching times. You can choose between: ON/OFF times or times with duration ON.

Stocking Density

The minimum and maximum ventilation is dependent on the stocking density in the room. The stocking density per room can be entered in various ways. It is possible to display the stocking density and the ventilation in percentages or in m3 per animal.

Central Weather Station

The weather situation can influence the prevailing barn conditions. For this reason, Thomas Climate has the ability to measure and record the weather influences, such as temperature, RH, wind speed and wind direction. If necessary, Thomas Climate can react to these, so that your animals always have a perfect climate.


Thomas Climate has two types of messages: a warning or an alarm. In the case of a warning, a message will appear on Thomas Climate display. In the case of an alarm, the alarm contact will also be broken. All messages are saved in the alarm log with start and end times.

Fire Alert

The fire alert system works by monitoring a number of configurable temperature sensors. If a sensor measures a temperature higher than 58 °C or if the measured temperature rises by more than 5 °C within 1 minute, a fire alert will be issued.
