Page 7: Guidelines
DOL 834 CE 1 Guidelines This user manual deals with the daily operation of the house controller. The manual provides the fundamental knowledge about the functions of the controller that is required to ensure optimum use of it. Some functions are optional and only used in specific set-ups of the house controller. These func- tions are shown with an optional icon. -
Page 8: Product Description
The house controller is available in two variants, both of which are used in a total insect ventilation system: • DOL 834 Insect (section ventilation) • DOL 834 CE Insect (central exhaust) The climate controller is operated via a touch display with graphical views of e.g. the ventilation status, icons and curves. - Page 9 See the section about CO2. DOL 834 CE is used for controlling the pressure in an exhaust duct for a central exhaust ventilation system. It can also be used in houses where fresh air needs to be heated up or cooled down before it enters the house.

Page 10: Operating Instructions
DOL 834 CE 3 Operating instructions 3.1 Operation The climate and production controller is operated by means of the touch display. The view in the display is called a page. You can scroll both up/down and right/left to see the entire page. -
Page 11: Daily Use
DOL 834 CE 3.2 Daily use The controller is operated via created pages giving access to settings and information. We recommend that you create pages with the content you need for daily operation. The pages provide infor- mation about and status of the operation. Furthermore, the content of the pages works as shortcuts to the set- tings menu for quick and easy access to changing settings. -
Page 12: Activity Log
DOL 834 CE 3.3 Activity log The controller registers operation, events and alarms with the information of when they took place and when they were deactivated. It often happens that several alarms follow each other because one defective function also affects other functions. -
Page 13: Selecting Default
DOL 834 CE 3.4 Selecting default pages The climate and production controller comes with a number of default pages that vary according to the ventila- tion system and animal type. In order to simplify the set-up of controller, you can use default pages. - Page 14 DOL 834 CE The new page is displayed. Press the gear wheel icon in the bottom right corner.

Page 30: Maintenance Instructions
DOL 834 CE 7 Maintenance instructions The house controller requires no maintenance to function correctly. You should test the alarm system every week. Use only original spare parts. Note that the service life of the house controller will be extended if it stays connected all the time, as this will keep it dry and free from condensation. -
