Notes concerning alarm systems
Breakdowns, malfunctions or faulty settings may cause substantial damage and financial losses when regulat-
ing and controlling the climate in a livestock house. It is therefore essential to install a separate, independent
alarm system that monitors the house climate concurrently with the climate and production controller. According
to EU-directive No. 98/58/EU, an alarm system must be installed in all mechanically ventilated houses.
We would like to draw your attention to the fact that the product liability clause of general terms and conditions
of sale and delivery specifies that an alarm system must be installed.
In case of an operating error or inappropriate use, ventilation systems can result in production
losses or cause loss of lives among livestock.
We recommend that ventilation systems should be mounted, operated and serviced only by
trained staff and that a separate emergency opening unit and an alarm system be installed as well
as maintained and tested at regular intervals, according to terms and conditions of sale and deliv-
ery.
Installation, servicing and troubleshooting of all electrical equipment must be carried out by quali-
fied personnel in compliance with the applicable national and international standard EN 60204-1
and any other EU standards that are applicable in Europe.
The installation of a power supply isolator is required for each motor and power supply to facilitate
voltage-free work on the electrical equipment. The power supply isolator is not included.

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.
If a function is not used, e.g. 24-hour clock, it is not shown in the user menus of the controller. The manual may
therefore contain sections that are not relevant to the specific setup of your controller. See also the Technical
Manual or, if necessary, contact service or your dealer.
This manual's Operating Instructions consists of a general introduction, which describes briefly how to operate
the house controller.
This is followed by descriptions of the controller functions.

2 Product description
DOL 834 is a house controller developed for insect farming systems with a focus on the soldier fly and meal-
worms. It is thus intended for breeding and growth of larvae and pupae, but can be adapted to most types of in-
sect farming systems.
Insect farming is an intensive form of production. The insects generate a lot of heat, just like the level of CO2
and NH3 can be high in relation to the room. It requires efficient ventilation with high and uniform air change en-
suring good production conditions throughout the insect house.
DOL 834 meets the insects' special needs for climate control with recirculation, humidification, ventilation boost
and curve control, which is performed on an hourly basis. The ventilation can be controlled as an equal pressure
system and as a central exhaust system.
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 views may be adapted in accordance with the user requirements so that the most frequently
used working procedures are easily accessible.

Figure1: Ventilation components in an insect house with grow-out crates
In production systems for soldier flies, humidity control and removal of humidity with the ventilation air is crucial
in pupa, nursery and growth sections. The flies are produced here in a moist substrate, and the heat production
of the larvae is released especially in the form of water vapor.
During the growth-out period, the moisture content of the substrate changes. Typically, the substrate has a dry
matter content of approx. 30 % at the start, while at the end it must have a dry matter content of 50-60 %. Dur-
ing the production it is important to maintain such a high moisture content in the substrate that the larvae can
eat the dry matter. The larvae have no teeth and therefore they have to suck in the food. Likewise, it must be
avoided that the surface dries out, as this can make the substrate inaccessible to the larvae, and cause it to
form cakes/crusts, which will be sieved off together with the larvae at the end of production. At the end, it must
be so dry that the larvae can be sieved from the frass. See the section about Humidity.

Figure2: Ventilation components in an insect house with fly cages.
In fly houses, the focus is on good air quality. Here the flies hatch, after which they mate and lay eggs in fly
cages over a period of 10-14 days. They consume no nutrition and only a little moisture from a damp surface.
Therefore, they have a very modest heat and humidity production. However, it is also important to avoid humid
areas inside the fly cages. 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.

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.
For instance, a flap alarm can be followed by a temperature alarm as the controller cannot adjust the tempera-
ture correctly with a defective flap. Thus, the previous alarms give you the possibility of following an alarm
course back in time to detect the error that caused the alarms.
The activity log contains information about alarms such as:
• When the alarm occurred.
• When the alarm ended.
• The value that triggered the alarm.
Other active alarms are marked on the list.
• Hard alarms are marked in red.
• Soft alarms are marked in yellow.
• Deactivated alarms are gray.
The icon for Activity log indicates the number of active alarms, as long as an alarm situation has not ended.
Furthermore, it is displayed when a value/setting was changed and when.
