c. Non-Brood Area Diff From Target: heaters
in areas other than the current active area
(such as in the grow end of a two grow area
house during brood 1) operate by this
temperature setting.
2. Stir Fans
a. Minimum Ventilation Cycle Offset: the
stir fans operate with offset from the
termination of the minimum ventilation
timer fans. If the offset is 0, the stir fans
turn on when the minimum ventilation
fans turn off.
b. Operate Duration (sec)
: the stir fans
operate for this length of time.
c. Set Function (Stop-0/Cont-1)
: If you
choose the Stop option, then the stir fans
will cease to operate at their ON
temperature. If the option is Continuous,
then the stir fans run continuously above
their ON temperature, and cycle below
that.
3. Radiant Heaters
a. Radiant Heater High Differential: In
Standard Mode, low level radiant heaters
operate according to their on and off
settings specified in the Control Menu |
Temperature and Timer Settings just as do
the normal heaters. Each high level
radiant heater operates at a differential
temperature from the corresponding low
level heater. That is, they turn on the
specified number of degrees below the
low level heater on temperature, and off
the same number of degrees below the
low level heater off temperature.
b. Radiant Ignition Time (sec)
: some
radiant heaters require a separate ignition
control. When turning a radiant heater on,
both the low, high and ignition relays
operate in unison for this length of time to
ensure proper ignition. After this time the
ignition turns off, and the both the low
and high level relays operate according to
their temperature settings.
4. Temperature and Humidity
a. Temperature Curve Offset: Use the hot
key combinations up + enter and down +
enter to adjust the present temperatures
above or below the curve. You can also
view and adjust them in this system
parameter.
b. Set Temperature Change Reminder
Differential: This sets the point at which
the Platinum Plus will remind you to
check your backup thermostats when
temperature settings change.
5. Light
a. Sunrise Time (minutes): This sets the length
of time to move to a new intensity setting on
an optional light dimmer starting with the
programmed Start time (see Control Menu |
Light).
b. Sunset Time (minutes)
: sets the length of
time to move to a previous setting or to off, so
that the destination intensity is reached at the
programmed End time (see Control Menu |
Light). This ensures that the end point is
reached coincident with any light relays
turning off on the same setting.
c. Minimum Analog Voltage
: calibrates the
zero light intensity control voltage.
d. Maximum Analog Voltage
: calibrates the
100% light intensity control voltage.
e. Analog Output Channel
: the optional analog
output card has eight channels. You can
assign the light dimmer control to any of the
first seven channels. The eighth channel is
reserved for variable speed fan control.
6. Static Pressure
a. Wind Gust Delay Time (seconds): the
Platinum Plus waits this length of time to
respond to unexpected pressure changes.
Changes occurring coincident with fan
operations do not incur a delay; in such cases
the Platinum Plus anticipates the pressure
change and pre-adjusts inlet openings.
b. Pressure During Tunnel (N-0/Y-1)
: select
whether to use the tunnel pressure settings, or
to simply open the tunnel curtain without
regard to pressure.
c. Transitional Tunnel (N/0/Y-1)
: select
whether to supplement side ventilation
pressure control with the tunnel inlet curtain
in the event target pressure cannot be reached
with the side vents already at 100% open. In
some cases, the maximum number of fans in
cross ventilation exceeds the capacity of the
side vents to open enough to obtain target
static pressure. If this option is yes, then the
Platinum Plus opens the tunnel curtain
enough to meet the target pressure.
d. Minimum Ventilation Using Inlet or
Tunnel Curtain: some producers do not have
side inlets for pressure control during
minimum ventilation. They can optionally use
the tunnel inlet curtain for the same purpose.
e. Emergency Pressure Delay (seconds)
:
length of time to wait for a high pressure
above the high alarm setting before entering
