SPEED CONTROL - SERVOMOTOR Instruction Manual
Periodical airing
Airing is one of the functions performed by the controller, which activates when the temperature in the
room drops below the temperature value set by the user. Such function guarantees a constant air
circulation inside the breeding room to provide a regular air supply for the animals, at the same time
extracting already used air. There are three parameters available in the airing mode:
•“Time airing” - indicates the time duration of the activated ventilator (in minutes)
•“Break time” - determines the amount of time during which the ventilator is not working
•“Airing level” - indicates the power value of the ventilator in “Time airing”
For example, the configuration 60s/120s informs, that the airing process is in the time mode. It simply
means that the ventilator is turned on for 60 seconds and then it becomes turned off for the next 120
seconds – one minute of work, then a two-minute break.
All of the parameters above can be set by the user. However, there are some rules to be remembered
while adjusting the values in the airing process:
•airing is turned on only when the temperature in the piggery drops below the value previously set
by the user,
•the primary function of airing is to provide a constant fresh air supply for the animals, and not
maintaining the temperature that had been set in the room,
•airing the room frequently for short periods is strongly recommended
•longer airing periods should be avoided, because they can lead to major temperature variations
•the parameters must be adjusted properly according to the behaviour of animals in the breeding
room and all the conditions that occur not only inside, but also outside of the building.
•it is possible to completely turn off the airing function; to do so, both in time and percent mode,
the values should be set to zero e.g. 0/120s for the time mode or 0%/3min for the percent mode.
Device working scheme
The controller smoothly regulates the ventilation from “Min 1” to
“Max1” within the range of “Setting temp.” and “Airing band 1”.
“Vent 2nd stage” will be active above that range and “Level min.
1” will immediately change to “Level min. 2”. As the temperature
continues to grow, it will change to “Level max. 2” at the end of
“Airing band 2” range. If “Airing band 2: equals “0”, but “Level
max.1” is enabled, “Vent. 2nd stage” will be activated, causing further increases in the temperature to
have no effect on changes in the ventilation process (dotted part of the graph). In the case of the
temperature in the room dropping below the “Setting temp.”, the controller turns on the airing process
periodically and if it continues to drop, heating is additionally activated. Every action is based on the
adjustments that the user had implemented before. When the temperature in the piggery has different
parameters than those set by the user, the programme of the controller may connect with the alarm
control panel and activate the alarm.
Controller programming
The sensor has a built-in set of default settings entered to the non-volatile device memory in two cases:
•during the first device start-up
•when the memory data error occurs
In case of the power outage, the controller is not losing any of the settings that had been adjusted earlier
by the user.
