occupied deadband Screen.
Enter
an occupied deadband. This is +/- the
setpoint where no control is done, during
the occupied time period. This is a num-
ber from 0 to 100% of input span.
unoccupied deadband Screen.
Enter
an unoccupied deadband. This is +/- the
setpoint where no control is done, dur-
ing the unoccupied time period. This is a
number from 0 to 100% of input span.
AI2 Control Mode Screen.
Choose
the control mode for AI2. Select from
Remote Setpoint, Reset or Monitor.
Select Monitor if AI2 is not used. Note:
Must be MONITOR if dew point control
is selected.
Setpoint Low Limit Value Screen.
Enter a setpoint low limit value. The set-
point will not be allowed to be set lower
than this setting.
Setpoint high Limit Value Screen.
Enter a setpoint high limit value. The set-
point will not be allowed to be set higher
than this setting.
Setpoint Screen.
Enter a setpoint value
for control. (This screen does not appear
if the AI2 Control Mode is chosen to be
Remote Setpoint.)
Reset Setpoint Screen.
Enter a setpoint
value for AI2. (This screen only appears
if the AI2 Control Mode is chosen to be
Reset.)
Reset Ratio Factor Screen.
Enter a
reset ratio factor. This is the number
of units +/- (%RH, °F, etc.) that the AI1
Setpoint is raised when the AI2 input
falls 1 unit below its setpoint. (This
screen only appears if the AI2 Control
Mode is chosen to be Reset.)
Analog output Range Screen.
Choose
whether the analog output range will be
0-20mA or 4-20mA.
Analog output Action Screen.
Choose
whether the analog output will be direct
or reverse acting. (When DI2 is set to
Aquastat, the output will automatically
reverse action when DI2 is closed.)

Analog output Type Screen.
Select
whether the analog output will be
modulated from an endpoint or the mid-
point. Note: Set to MIDPOINT if dew
point control is selected.
Analog output unoccupied Action
Screen.
Select whether during unnoc-
cupied mode the analog output will
modulate go to 0 to 4 mA, or go to 20
mA.
Analog output Mode Screen.
Choose
whether the analog output mode will be
Heat or Cool. With heat mode, modula-
tion occurs when the input is below the
setpoint. With cool mode, modulation
occurs when the input is above the
setpoint. (This screen only appears if
the Analog Output Type is chosen to be
Endpoint.)
Analog output Setpoint offset
Screen.
Enter a setpoint offset. This is
a value below the setpoint (Heat Mode)
or above the setpoint (Cool Mode)
where the analog output begins to
modulate. (This screen only appears if
the Analog Output Type is chosen to be
Endpoint.)
Analog output unoccupied Action
Screen.
Choose whether the unoccu-
pied analog output will be Modulating,
0mA or 4mA, or 20mA.
Analog output Proportional Band
Screen.
Enter a proportional band.
This is in percent of input span. It is
how much AI1 must change to have the
analog output change from 0 or 4 mA
to 20mA.
Analog output Integral Value Screen.
Enter a integral value. This a number
between 0 and 100%. Choose 0 if inte-
gral is not used.
Analog output differential Value
Screen.
Enter a derivative value. This a
number between 0 and 100%. Choose
0 if derivative is not used.
digital output 1 Mode Screen.
Choose whether the mode for digital
output one will be Heat or Cool. With
heat mode, relay energizes when the
input is below the setpoint. With cool
mode, relay energizes when the input is
above the setpoint.
digital output 2 Mode Screen.
Choose whether the mode for digital
output two will be Heat or Cool. With
heat mode, relay energizes when the
input is below the setpoint. With cool
mode, relay energizes when the input is
above the setpoint.
