Chapter 10: House/barn setup
Table 10-8 CFM per head ventilation operation (cont'd.)
Night ventilation reduction You can reduce minimum ventilation at night. Night
reduction directly affects the minimum ventilation refer-
ence value either in cfm or cfm/head. It works the same
way with manual and auto (curve) minimum ventilation
levels. Day and night reference times are set during ini-
tial configuration.
CFM for pre heat mode Set airflow required during Pre-Heat Mode
CFM for clean mode Set airflow required during Clean Mode
Inlet compensation
Inlet temperature compensation can work with ceiling, sidewall, or Tunnel inlets.
Table 10-9 Inlet temperature compensation (settings in the Power ventilation setup)
Field Description
Ceiling temperature Temperature difference compensation for ceiling inlets
Ceiling limit Maximum compensation applied to calculated value of
opening of ceiling inlets in the setup grid (if calculated
value = 30% and limits = ±10 this means that inlet
cannot move to opening higher than 33% and lower
than 27%)
Sidewall temperature Temperature compensation for sidewall inlets
Sidewall limit Maximum compensation applied to calculated value of
sidewall opening into setup grid
Tunnel limit Maximum compensation applied to calculated value of
opening of ceiling inlets in the setup grid
Inlet position reset
The inlet position reset parameters are shown only if there are time based inlets of any type in the house/
barn (ceiling, sidewall, Natural, Tunnel with or without whisker switch). A potentiometer based inlet with a
potentiometer defect is controlled as a time based inlet and uses time based inlet reset default settings.
Field Description
Movements w/o hitting limit switch Number of open or close moves without reaching the
limits that would cause a reset of inlets
Close only if younger than - check box Activate the option of considering age as a condition to
"close only" reset mode
Close only if younger than - age Maximum age for the "close only" reset. Below this
age, the inlet cannot reset by opening completely ,only
by closing completely.
Open only if older than - check box Activate the option of considering age as a condition to
"open only" reset mode
Open only if older than - age Minimum age for the "open only" reset- above this age,
inlet cannot reset by closing completely, only by open-
ing completely.
