7. Current Stir ON Time
Current Stir ON Time is the current amount of Stir On Time. If (TMP) is displayed the Stir Fan
(s) are on by temperature.
The "stir on" Timer is different than
the other Timers. It can only be at-
tached to Stir Fan Outputs in the "Out-
puts" screen. The "stir on" time value
is set in this screen. The purpose of
this feature is to allow you to cause a
Stir Fan Output to run for the "stir on"
amount of time immediately following
the end of the Minimum Ventilation
Timer's "on" time. Because of this, the
Stir Fan is synchronized with the min-
imum ventilation Timer. The "stir on"
setting can be any value up to the "off"
time of the minimum ventilation Tim-
er. The Stir Fan Outputs will come on full when the temperature rises to the "on" temperature val-
ue set in the "Outputs and Temperature" screen.
8. Temp. Influence
is the amount of time added by Ventilation timer ramping- If the sensor(s) that are assigned to the
Minimum Ventilation fan(s) temperature is at or below set temperature then the fans will use the
ON and OFF times that are listed for the Minimum Ventilation Timer. If the sensor (s) assigned
to the Ventilation Time Ramping temperature is between set temperature and the fans' ON tem-
perature the Control will adjust the amount of ON time between the Min Ventilation value and the
Max value. The OFF time will be adjusted by the same amount of time that the ON is adjusted,
thus keeping the total cycle time constant. The temperature is checked 30 seconds before the be-
ginning of the ON time cycle of the Minimum Ventilation Timer. Once the fans' temperature sen-
sor(s) reach the fans' ON temperature, the fan will turn on and run continuously until the fans' OFF
temperature is reached.

Example:
The set temperature is 70.0°F and the fans assigned to the Min Vent timer ON temperature is
72.0°F. The Minimum Ventilation Timer values are 30 seconds ON time and 270 seconds OFF
time. The maximum ON time is 210 seconds. If the sensor(s) assigned to the Ventilation Time
Ramping temperature is 71.0°F at the beginning of the anticipation cycle, then the fans will have
an ON time of 125 seconds and an OFF time of 175 seconds.
9. RH Influence
The actual amount of influence time the RH function is adding to the minimum ventilation timer.
The Control may not always add the full amount of time if the amount of influence would add up
to be more than the maximum allowed.
