Table 12: Survey of the menu for stir fans (changeable values are highlighted in bold types).
A stir fan improves circulation of the air and thus provides a more uniform temperature in the
livestock house.
The Viper can regulate up to six stir fans at a time. Each stir fan can be regulated in connection with a
heat source, a temperature sensor or a 24-hour clock.
Controller Stir fan – method of operation
Heat source
(up to 6)
1) Together: The stir fan runs while the heat source supplies heat, but starts and
stops with a set time delay (Start delay/Stop delay).
2) Separate: The stir fan runs after the heat source has supplied heat. It starts
with a time delay (
Start delay) and runs for a set period of time (Runtime).
Temperature
sensor (up to 2)
1) One temperature sensor: The stir fan runs for a set ON-time, when the
temperature deviates more than set in Temperature setpoint.
2) Two temperature sensors: The stir fan runs for a set ON-time at a set
temperature difference between the two sensors.
24-hour clock
1) The stir fan runs for a set ON/OFF-time at set times.
