Vision Control

The Vision Control is an intelligent storage computer that controls temperature and relative humidity as well as CO2 level by regulating fans, hatches, heaters and refrigeration devices. This results in minimal storage losses as well as optimal energy saving.

Clear and informative

The screen of the Vision Control shows a diagrammatic view of the storage and of the refrigeration. The status of the product and the installation are cleary shown. Furthermore, the Vision Control gives the uses automated tips for the optimal settings of the climate computer.

Energy management

The Vision Control energy management module (15 inch model) is an energy efficient module. By setting the maximum allowed energy consumption and setting the system priorities, the storage and other energy consuming facilities are automatically switched on or off. This results in the least storage losses and highest energy savings.

Weather in Control

Weather in Control is an optimalization module which, based on a 10-day weather forecast, takes intelligent decisions regarding the ventilation and refrigeration strategy. The module’s advantage is maintaining a more precise desired storage temperature of the product with lower weight loss and reduced energy costs. The profit of the system is being made by making efficient use of the available moments when cold outside air is available. Weather in Control will adjust the climate computer’s settings so that, depending on the situation (periods with either predicted lower or higher temperatures), start sooner or later with external ventilation or mechanical refrigeration. The decisions are made based on:

  • expected outside temperatures
  • the set target temperature
  • energy rate structure
  • possible present mechanical refrigeration

Online control

The climate computer can be controlled via internet connection (PC, tablet, smartphone). This gives the user continuous insight in the storage facility and the possiblity to adjues the settings.

Tolsma Alert

Tolsma-Grisnich’s Vision Control climate computer is developed to keep a close grip over the products that are being controlled by the system. If desired, our storage specialists can support the Vision Control to further increase the storage efficiency. For this purpose, the Tolsma-Alert service package was developed. Ask one of our storage specialist for the possiblities.

The Vision Control:

  • Optimal control of temperature, R.H. and CO2
  • Automatic control of ventilation, refrigeration and heaters
  • Maximum energy saving
  • Lowes storage losses
  • Available in 10 inch and 15 inch screen


The Tolsma app

Using the renewed Tolsma app, you can now view the data from the Vision Control climate computer (temperatures, running hours, status, alerts) on your smartphone or tablet. You can download the app from the Apple App Store or Google Play Store. The app is only suitable for Android smartphones or iPhones, and some elements of the app can only be used in combination with an app subscription.

It has already been possible to benefit from all facilities provided by the free Tolsma app for some time:

  • Viewing running hours and storage measurement values at a glance
  • Receiving push notifications for alerts
  • Up-to-date storage tips.


The version of the app which involves a paid subscription provides enhanced features:

  • Control status overview of groups within Vision Control
  • Read-out and adjustment of the major settings of your Vision Control.


If you would like to make use of these new functions (control status and settings), please register for a subscription. To register for a subscription, or for any other questions, please contact your Tolsma representative or send a mail to appsupport@tolsma.com
