Pswrd
Set at System Manager.
DI1
Set to
Filter
by System Manager.
(Value cannot be changed)
(Filter):
A Filter alarm is displayed. This alarm can be connected to
a differential pressure switch that monitors a filter.

Disabled by System Manager.
MenuScro
Gives the option of having the
display continuously scroll the
parameters.

(off):
The scroll is inactive.

Access
(2). Value cannot be changed.
Pwr del
2
Sets the delay time period at
thermostat controller powerup, or
each time power is removed and
reapplied, before any operation
(fan, heating, or cooling) is
authorized. Also can be used to
sequence the startup of multiple
units in one location.
Default:
10.0 sec
Range:
10.0
to
120.0 sec
Frost pr
Provides a minimum heating
setpoint of 42.0°F/5.5°C to prevent

Pband
Proportional Band used by the PI
temperature control loop of the
thermostat controller.
Pband is not converted with C or F
scale and is always shown with a
range of 2 to 8.
Default:
2
(
2.0F°/1.1C°
)
Value
F Scale Pband/C Scale Pband

6
6.0F°/3.3C°
7
7.0F°/3.9C°
8
8.0F°/4.4C°
Note:
The use of a larger proportional band is not to use the
thermostat controller as a discharge air controller device. The use of
a larger proportional band can be used to solve issues for flawed
HVAC design with basic sizing and thermostat controller location
errors that cannot be worked around.
