Setting the Stir Fan Start and Stop Temperatures
1. Using the menu select arrow keys, navigate to Start / Stop Temps→Stir Fan .
This parameter is accessible if the stir fan output is enabled.
2. Set the following parameters:
Hot temperature Select Yes if you want to use the stir fan output in hot temperature
conditions.
Cold temperature Select Yes if you want to use the stir fan output in cold temperature
conditions.
Probe differential Select Yes if you want to use the stir fan output to reduce temperature
differences between probes.
Hot start/stop temperature If stir fans are used in hot temperature conditions, set the room tem-
perature above which the output starts and below which it stops.
Cold start/stop temperature If stir fans are used in cold temperature conditions, set the room tem-
perature below which the output starts and above which it stops.
Probe differential If stir fans are used to reduce temperature differences between
probes, set the maximum allowable temperature difference. The
output starts when the difference between two probe readings
exceeds this value.
Cold and probe timer Stir fans operate according to a timer when they are used in cold tem-
perature conditions and when they are used to reduce temperature
differences between probes. Set the on and off times of the stir fan
timer.
