ignition relay stays on to help ignite low
level radiant heater.
Minimum/Maximum Level, Precision
Mode
The Minimum/Maximum Level menu sets
the current absolute minimum and maximum
ventilation levels available to the Platinum Plus.
You have three minimum maximum level
choices:
1. Min/Max by Growth Day
2. Min/Max by Time of Day, and
3. Soft Min/Max which provides one minimum
level at low temperature you can set, and a
second minimum level that you can set at a
warmer temperature. Between the two
temperatures, the Platinum Plus interpolates
the minimum level if the outside
temperature sensor is selected. If the inside
temperature is selected, then the Platinum
Plus interpolates levels while decreasing
ventilation levels, but remains at the lowest
level reached while temperature increases
until reaching the heat temperature. At this
point the active minimum level because the
upper minimum level.
To select the type of minimum/maximum
level table, go to Control, Control Mode, choose
Min. Max. Level Control
and press Enter to pop
up the selection list.
If you have selected the soft minimum, the
Platinum Plus provides two Help | Set
parameters:
1. Differential Below Heat for Soft
Minimum: the temperature below heat at
which to use the cold or low temperature
minimum.
2. Temperature Choice for Soft Minimum
:
Select either the inside temperature or the
outside temperature to govern the soft
minimum. If you choose the outside
temperature, the Platinum Plus interpolates
the minimum level according to this
temperature and changes level according to
the usual rules. However, if you choose
inside temperature to govern the minimum
level, it operates by the usual rules while
temperature is decreasing, but then remains
at the lowest level reached until the
temperature climbs back to the heat
temperature (when the heaters turn off). At
this point, the minimum level again becomes
the higher soft minimum to provide an
increase in air flow.
Humidity, Precision Mode
Up to 20 humidity treatment levels are available
in precision mode. You can set several treatments
for a particular growth day at various humidity
levels. The Platinum Plus sorts the table in order of
growth day, then humidity level when you exit from
the menu. The highest humidity setting less than
actual humidity applies. The controller waits the
applicable ‘Interval’ that you set in minutes, and
increases ventilation one level for at least the length
of time specified in ‘Duration.’ The usual level
increase/decrease rules apply once outside of the
duration during which humidity treatment occurs.
There are two Help | Set parameters:
1. Humidity Band
: this is the usual on/off
differential or Happy Zone with respect to
inside humidity.
2. Humidity Treatment Below Heat
: the
increased ventilation resulting from humidity
treatment may cause temperatures below target,
or even lower. Select whether humidity
treatment may continue if average temperature
goes below the heat setting.
Cool Pad
The Cool Pad setting provides 20 lines to
program the water control for the cool pads.
1. Program applicable growth days in column 1.
You can set several lines for a particular growth
day. They will sort into growth day order when
you exit the menu. Higher growth days will
supersede earlier growth day settings when the
growth day arrives. The settings then apply until
the next growth day setting, so you need not set
each growth day.
2. Set the start time that applies to a particular line,
and the end time in their columns. The time is
in Military or 24 Hour format, so afternoon
times will have the hours equal to 13 or greater.
3. Enter the relative differential temperature from
your Tunnel On setting in Temperature and
Timer Settings. It is possible to enter a negative
differential by pressing the +/- key after
entering the number of degrees under Tunnel
Differential.
4. Enter the To Humidity setting. This is the
maximum humidity at which that line will
apply.
5. Enter On seconds. The Cool outputs will not
operate at all if there is nothing in the On
setting, so it is mandatory to change it to a value
other than 0.
6. Enter the Off seconds if you wish to have the
cool system cycle on and off. This is optional
according to your needs.
