As soon as it gets warmer outside, the house temperature may also rise. If no outside temperature sensor is installed, a temperature alarm may go off unnecessarily. This wastes time and causes disruption. An outside temperature sensor solves this problem. You can use the farm computer to automatically raise the (relative) maximum alarm limit based on the current outside temperature. This is known as outside temperature compensation. It’s particularly useful in warm weather.
If the outside temperature rises above the set temperature, the maximum temperature alarm limit automatically adjusts upwards in line with the outside temperature. This function applies to all control modes, except for nest heating. This compensation prevents the alarm from being triggered unnecessarily at high outside temperatures. However, the adjusted alarm limit can never exceed the set absolute temperature limit.
If the current temperature rises above the absolute value, for example 35°C, an alarm is triggered. This absolute alarm limit serves to warn you that the pen temperature has become far too high. This is the point at which you, as a livestock farmer, must take additional measures to protect the animals.
Figure 1.
See Figure 1. Here you can set the alarm limits for the room temperature. If you are using an outdoor temperature sensor, temperature compensation will be activated. The (relative) maximum alarm limit will then be adjusted automatically. See the examples below for further explanation.
Explanation:
Situation 1: Outside temperature < Set house temperature -> Calculated alarm limit = Set house temperature + Set maximum alarm limit.
Situation 2: Outside temperature > Set temperature -> Calculated house temperature = Outside temperature The calculated alarm limit shifts upward to prevent unnecessary alarms.
Situation 3: Maximum alarm limit > Absolute alarm limit -> Maximum alarm limit = Absolute alarm limit The calculated alarm limit is capped at the absolute maximum. The alarm limits displayed are calculated values, based on factors such as the set house temperature limits and the control system’s temperature settings.
It is also important to note that, for the poultry computers, the setting for whether or not the maximum alarm limit is compensated for when a cooling system is in use, can be adjusted: Cooling system settings > Compensation > Maximum alarm limit > auto / always
Always: The outside temperature compensation functions as described above, increasing the maximum alarm limit at higher outside temperatures.
Auto (default): The increase in the alarm limit is disabled when cooling is installed and activated (even if the system is not actively cooling).
In short, warmer weather doesn't have to lead to false alarms. Thanks to an outdoor temperature sensor, the alarm limit automatically rises as the temperature increases. This helps to avoid unnecessary concern and manual work. All in all, this saves time straight away.
