Minimum Speed Curve
Temperature Curve
NOTE:
If the room temperature falls below "Set Point - 5.0
o
F (2.8
o
C) - heater offset
- heater 1 differential", the fans will begin to run at the minimum speed
specified for the first point of the curve and will continue to do so as
long as the room temperature remains below the set point. When the
room temperature rises above the set point, the fans will return to the
current minimum speed, calculated according to the minimum speed curve.
The user can define a minimum ventilation speed curve to adjust the Stage
1 minimum speed automatically over a given time period. Each curve is
defined by six points. Each point specifies a day number and a fan speed
for that day. Once the points are defined, the minimum speed curve must
be activated. When the minimum speed curve is activated, the controller
adjusts the Stage 1 minimum speed every hour in a linear fashion be-
tween two consecutive points.
When the last point of the curve is reached, the curve is deactivated. The
controller maintains the minimum speed specified for this point until the
curve is reactivated or until a new single minimum speed is specified using
the first method.

Adjusting the Mist Offset
The mist offset is the temperature difference from the set point at which the
mist units turn off. The offset can be adjusted between 0.5°F and 40.0°F
(0.3°C and 22.2°C).
n
Set the parameter selection
knob to
M I S T — T I M E R /
DIFF.
The current mist time
on is displayed, alternating
with the word "
On
".
n
Press the push-button twice.
The mist offset is displayed, al-
ternating with the letters "
OFT
".
n
Use the adjustment knob to set the offset to the desired value.
2
Adjusting Mist Differential
The mist differential is the variation in room temperature between the moment
the mist units turn on and the moment they turn off.The differential can be
adjusted between 0.5°F and 20.0°F (0.3°C and 11.1°C).
n
Set the parameter selection knob to
MIST — TIMER/OFFSET/DIFF
.
The current mist time on is displayed, alternating with the word "
On
".
n
Press the push-button three times. The current differential is displayed,
alternating with the letters "
diF
".
n
Use the adjustment knob to set differential to the desired value.
