Occupied Cool Setpoint Screen.
Set
the occupied cool setpoint.
Unoccupied Cool Setpoint Screen.
Set the unoccupied cool setpoint.
User Setpoint Limit Screen.
Enter the
number of degrees you want the user to
be allowed to change the preset occu-
pied setpoints up or down.
Override Time Screen.
Enter the
number of minutes (0 to 255) that the
SZ1018 will maintain occupied setpoints
when overridden.
Stage Mode Screen.
Choose whether
stages 1 and 2 perform heating or cool-
ing functions, Heat & Cool or whether
both stages are to be disabled.
Stage 1 Offset Screen.
Enter an offset
value for stage 1. First stage is normally
0 offset. This screen does not appear if
stage outputs 1 and 2 are disabled.
Stage 1 Differential Screen.
Enter a
differential value for stage 1. This screen
does not display if stage outputs 1 and 2
are disabled.
Stage 2 Offset Screen.
Enter an offset
value for stage 2. This screen is not
displayed if stage outputs 1 and 2 are
disabled.
Stage 2 Differential Screen.
Enter a
differential value for stage 2. This screen
is not displayed if stage outputs 1 and 2
are disabled.
Control Mode Screen.
Enter whether you
want to control by temperature only (P) or
add a time factor (P+I). This is applies to
both the stage outputs.
Time Clock Output Screen.
Choose
whether the auxiliary output will be OPEN
during occupied periods (and closed during
unoccupied periods) or CLOSED during
occupied periods (and open during unoc-
cupied periods).
Modulating Output 1 Type Screen.
Choose whether the modulating output
will use Endpoint or Midpoint Control.
Modulating Output 1 Define Screen.
Choose whether modulating output one is
used for heat, cool or aquastat.
Analog Aquastat Selection Screen.
Choose whether to use the discharge air
sensor (T2) to determine whether analog
output 1 will be used for heating or cool-
ing. If NO is selected, the next screen is
skipped. If no is selected, DI 2 will function
as aquastat where the analog output will be
used for cooling with DI 2 open and heating
with DI 2 closed.
Analog Aquastat Input Screen.
If an
analog aquastat is selected, choose the set-
point to distinguish when hot or cold water
is available. If the discharge temperature
is below this setpoint, analog output 1 will
do cooling. If the discharge temperature is
above this setpoint, analog output 1 will do
heating.
Minimum Position Selection Screen.
Choose whether to set a minimum posi-
tion constraint for analog output 1. If NO is
selected, the next screen is skipped.
Zone Damper min. Position Screen.
Set the minimum position for analog
output 1.
Modulating Output 1 Action Screen
.
Choose whether the output will be direct
or reverse acting. (When DI2 is set to
AQUASTAT, the output will automatically
reverse action when DI2 is closed. When
Analog Aquastat is chosen).
Modulating Output 1 Range Screen.
Choose whether the modulating output
range will be 0-20 mA or 4-20 mA.
