2. Select the desired measuring units:
- Time display: AM/PM or 24 h;
- Temperature display: Celsius (°C) or
Fahrenheit (°F);
- Water: liters or gallons;
- Static pressure: Inches of water (“WC)
or Pascals (Pa).
* These settings are common to all programs of the
controller.
4.5.3. Probe Assignment
Principle of Operation:
This section explain how
to select temperature probes that are used to
measure the room temperature and how to assign
temperature probes that are used to control/
monitor the outputs of the controller.
House Temperature
: Most cooling outputs of
the controller operate according to the aver-
age temperature in the room. The user must
choose what temperature probes are used to
measure this room temperature.
Tunnel Fans (Tunnel Probe Set)
: The selec-
tion 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 distort the room
temperature. If the second probe set is
enabled in the Installation Setup (sec. 4.4),
you must assign temperature probes to this
second probe set.
Heating Outputs:
Each regular heating out-
put and each Hi Fire heating output operates
according to the average temperature of its
assigned probes.
Empty Zones:
A heating output that exclu-
sively uses probes that are not assigned to
the average room temperature is automati-
cally considered as being in an empty zone
(sec. 4.9).
Cooling Outputs:
In sidewall ventilation, cool-
ing outputs operate according to the average
house temperature; in tunnel ventilation, they
operate according to the average temperature
measured by user-defined probes.
Attic Vent:
The controller automatically in-
creases the
“On Time”
portion of the minimum
ventilation timer as the attic temperature de-
parts from its set point. Refer to section 6.4.3
for further information about this feature.
Main Breaker :
A probe can be used to moni-
tor the temperature of the main breaker so
that the controller can sound an alarm if the
breaker’s temperature gets too high. Note
that the breaker’s probe selection is common
to all programs.
