4.7.3. Probe Assignment
Cooling and heating outputs either run ac-
cording to the room temperature or according
to the average reading of chosen temperature
probes.
Room Temperature Sensors:
Most cooling
outputs of the controller (misting output,
tunnel fans, stir fans, etc.) operate according
to the average temperature in the room. The
user must choose what temperature probes
are used to measure this room temperature.
Probe Set 2:
The selection of probes that is
used to measure the room temperature can be
changed in tunnel ventilation to compensate
for changes in airflow patterns that can dis-
tort the room temperature calculation. If the
second probe set is enabled in the Installation
Setup (sec. 4.5), you must assign tempera-
ture probes to this second probe set.

the selected output: select “ “ to assign a
probe or select “- - -“ for probes that are not
assigned to the output.
A template is available at the end of this
manual to write down your selection of
sensors.
4.7.2. Probe & Water Meter Cali-
bration
You can slightly adjust the reading of each
probe input in order to obtain accurate and
uniform readings from all probes. In addition,
if a water meter is used, you must calibrate
its water flow rate.

(if required).
Temperature probes (indoor & outdoor) —
The reading of inside and outside temperature
probes can be adjusted of ±3°F (±1.7°C).
Relative humidity probe —
The reading of
inside and outside humidity probes can be
adjusted of ±3%.
Static pressure probe —
The reading of the
static pressure probe can be adjusted of ±
0.030”WC (± 7Pa).
Water meter calibration —
Specify the flow
rate of each water meter. It can be adjusted
from 1 to 100 gallons (or liters) per pulse.
4.8. Relay Assignment
Assigning Relays to the
4.8.1.
Outputs
You must assign On/Off relays to each output
of the controller. Use provided output stick-
ers to identify the function of each relay on
the faceplate of the controller.

Fan Stage 6 Relay Assignment
Select a relay then set its status as fol-
2.
lows:
: The relay is assigned to the out-
put;
- - -
: The relay is not assigned to the
output;
TMR : The load connected to the relay
will run in timer mode (available
on fan stage outputs only).
Relays 21-36 correspond to relays 1-16
of the external relay panel.
Proceed in similar fashion to assign relays
3.
to each output in use:
Fan stages 2-12 —
Fan stages can either ac-
tivate regular on/off relays and/or timer-based
relays. When a timer-based relay is assigned
to a fan stage, the relay runs in timer mode
when the fan stage is active. This is useful
to operate misting units for instance. To use
timer-based relays, set the relay status to
“TMR”
(see example above).
