Precision Mode Programming Steps

Temperature
Definition
Select the temperature sensors to use
for each function.
Use the +/- key to apply or
remove check marks.

Fan Air
Capacity
Enter the fan air capacity for each of
your exhaust and tunnel fans. Under
Help | Set enter the house dimensions
so the Platinum Plus can calculate
wind chill temperature corrections.
If you group fans using the
same as # relay codes, count
the group as a single fan.

Ventilation
Levels
1. Tunnel and Exhaust fans appear
automatically in the Ventilation
Table.
2. Program minimum CFM of air
ever to be used in level number
one.
3. Increase CFM slightly (20% to
50%) at each level, except the 1
st
tunnel level. At 1
st
tunnel level
maintain the same airflow or
decrease slightly on tunnel entry to
prevent yo-yoing.
4. The lower levels and early
transitional levels should use 0.0º
differentials temps.
5. Higher transitional levels may
benefit from differential
temperatures from target.
6. 1
st
Tunnel level NEVER uses a
differential temperature. Any
number in this level is ignored by
Platinum Plus.
7. Subsequent differential temps in
tunnel levels are relative to Tunnel
Curve from Control Menu |
Temperature Curve.
8. Be sure to enter 1
st
tunnel level
and maximum levels under Help |
Set parameters. Also set tunnel
exit temp as a diff from Tunnel
Entry Temp.
1. At each level mark desired
fans as cycle, continuous or
rotate using the +/- key.
2. Continuous fans run
without a break on that
ventilation level. Cycle
fans use the on/off times.
Rotate fans take turns on
the on/off cycle timer.
3. 1
st
Tunnel Level
temperature is controlled
by Control Menu |
Temperature Curve |
Tunnel Curve.
4. To replace OFF column
with Variable Speed Fan
choose Help | Set
Parameters and set Fan
Cycle Time to other than
300 for automatic Off
times to have 5 minute
cycle timer, or choose
another cycle time.
5. Take account of wind chill
with the differential temps.
Note that diffs are relative
to target below tunnel, but
to tunnel curve when in
tunnel.

Curtain Levels
Adjust curtain levels to match the
ventilation levels. Set the tunnel
curtain openings to match the tunnel

pressure in tunnel or
transitional tunnel to help side
