Menu
If temperature is being used as the summer/winter switch-over control value,
the summer and winter setpoints may be entered at this screen. Seasonal
lockouts for heat and cool may be enabled or disabled by choosing YES or
NO in the HEAT and COOL fields.
Alarm setpoints for occupied and unoccupied space temperatures and supply
air temperatures may be set at this screen.
Dehumidification and humidification setpoints, deadbands for these setpoints,
and minimum building temperatures may be viewed and changed at this
screen.
Menu
The standard week schedule may be set using this screen. Days of the week
are chosen in the field at the top left, and times are entered in 24 hour format
in the OCPD and UNOC fields. If temperature is being used as a schedule
control value, the temperature setpoint may be entered in the TEMP field.
If desired, the BCU's Optimum Start/Stop feature may be used on any of the
OCPD and UNOC times. To activate OSS, move the cursor to the field
directly to the left of the OCPD or UNOC field and press the dash "—" key.
An asterisk should appear in this field, signifying that OSS is active.
Overrides of the occupied/unoccupied status of an RTU may be configured
and ordered using this screen. The Timer-Default field shows the default
length of an occupied/unoccupied override. If desired, an override can be
ordered for a set number of minutes by entering a time in the Timer field.
SPC, SP, RT, P12, AF: Shows whether the space temp, supply air, return air,
compressor 1 proof, compressor 2 proof, and air flow inputs are present (1)
or absent (0). These values may be changed by moving the cursor to the
field and pressing the dash "—" key.
AUX1/AUX2: The auxiliary input types may be chosen by entering a two-digit
code in this field. Refer to Table 4-2 on page 11, and enter the code number
corresponding to the desired input type.
FN, H1, H2, C1, C2, ECO: Shows whether the fan, heat stage 1, heat stage 2,
cool stage 1, cool stage 2, and economizer outputs are present (1) or absent
(0). These values may be changed by moving the cursor to the field and
pressing the dash "—" key.
AUX1/AUX2: The auxiliary output types may be chosen by entering a two-
digit code in this field. Refer to Table 4-4 on page 14, and enter the code
number corresponding to the desired output type.
TYP: Shows whether the analog outputs (A01 and A02) are absent, (00),
controlling analog economizers (01), or controlling variable speed fans
(02). To change the value, enter 00, 01, or 02 in this field.
MIN%: The minimum percentage the analog output will be allowed to be.
MODE: The mode setting determines at what times the economizer damper is
allowed to modulate to the minimum percentage, either Always Open (00)
or During Occupied (01). Enter the desired setting in this field.
RTU analog outputs modulate economizer dampers and fans by sending
appropriate voltages to the analog economizers. By default, the outputs will
modulate from 0-10VDC. To specify a different voltage range, enter values
in the MINV and MAXV fields.
