Platinum Plus

Feed
The Platinum Plus feed clock
corresponds in capability to the light dimmer.
You can enter up to 50 feeding times according
to growth days, and use the same growth day
several times to program multiple feeding times
per day.
Program the feed clock just as you
would the Light clock. To simply turn the feed
on, enter a ‘1’ in the growth day of the first line,
and leave the rest blank.
You can set feed monitoring and feed
overrun alarms using the Digital Inputs in the
Install Menu, and relevant alarms in the
Management Menu | Alarm Settings.
The Feed relay codes are 106 Feeder,
108 Auger 1 and 109 Auger 2. There is no
difference in function between the three codes
for control purposes. The names provide you a
method of distinguishing the lines for your own
naming convenience only and can be reused on
several switches/relays.
Extra Systems
The Platinum Plus provides four extra
systems, or generic control programs. Relay
codes for the extra systems are 98 Ex. System 1
through 101 Ex. System 4
. They cannot be
reused, so to duplicate extra systems on several
relays you need to use the ‘same as #’ functions
starting at 123 As Relay # 1
in relay layout.
1. Each extra system as a Start Time, which is
when it may turn on (if the other parameters
allow it to).
2. The End time is when that system must turn
off.
3. From Temp: the system may be on only
above this temperature setting according to
its sensor selection.
4. To Temp: the system maybe on only below
this temperature setting according to its
sensor selection.
5. From Humidity: the system may be on only
above this humidity according to the inside
humidity.
6. To Humidity: the system may be on only
below this humidity according to the inside
humidity.
7. The On seconds must not be 0, or the system
will not operate. If there is a setting in the
Off seconds this is the on cycle time.
8. Off seconds may be used to cause the extra
system to cycle.
Pressure, Standard Mode
Enter Minimum Ventilation (or side vent)
pressure settings and tunnel pressure settings.
1. Low Pressure Setting
: enter the minimum
pressure setting for minimum ventilation and
for tunnel ventilation. The control will close the
appropriate device to increase pressure when
pressure is below this setting.
2. High Pressure Setting
: enter the maximum
pressure setting for minimum ventilation and
for tunnel ventilation. The control will open the
appropriate device when pressure is above this
setting.
3. Low Pressure Alarm
: enter the minimum
pressure for both minimum ventilation and
tunnel ventilation. The controller takes into
account periods when the fans cycle off to
prevent nuisance alarms. This parameter
provides an indication of actual air flow in the
building, and is particularly useful during high
temperature periods when the high temperature
alarm provides minimal service.
4. High Pressure Alarm
: enter the maximum
pressure allowed for both minimum ventilation
and tunnel ventilation. If the pressure remains
above this for the Emergence Pressure delay,
the control will enter Emergency Pressure
operation and open all known air sources. See
the Help | Set parameters below.

1. Wind Gust Delay Time (sec)
: 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.
2. 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.
3. 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.
4. 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.
5. Emergency Pressure Delay (seconds)
: length
of time to wait for a high pressure above the
