3.8 Side Cooling
This section is relevant only to houses with side cooling systems.
Humidity to stop side cooling
Requirement incl. humidification
Table 5: Overview of the complete Side cooling menu.
Cooling is used in houses where ventilation alone cannot reduce the inside temperature sufficiently.
Cooling has the advantage over ventilation in that it can bring the inside temperature down below the outside
temperature. On the other hand, cooling will also increase the air humidity in the house.
The combination of a high inside temperature and high air humidity can be life-threatening to
the animals. As cooling makes the house humidity increase, DOL 53X automatically disconnects
cooling when the house humidity exceeds Humidity to stop side cooling (normally 75-85%,
factory setting: 85%).
The number of degrees by which the temperature is to increase above the
Temperature setpoint + Comfort temp. before cooling starts.
Humidity to stop side
cooling
The air humidity percentage that makes DOL 53X stop the cooling function.
Furthermore, a humidity limit can be set for the tunnel cooling.
Display of the current cooling requirement.
Requirement incl.
humidification
This reading is displayed when humidification is also connected to the relay for high-
pressure cooling system. The reading shows how big a percentage of the high-
pressure cooling system's capacity that is currently active.
This feature is particularly useful in hot and dry areas where high-pressure cooling
will run alternately to the humidification, respectively to cool and increase humidity.
