Offset
The term "offset" applies to the Set Temperature and Minimum Ventilation Timer
curves only. If you manually adjust either the Set Temperature or the Minimum
Ventilation Timer settings, while the curve is on, you create an "offset" to that curve
relative to it's "curve value". The "curve value" is not changed. (see the "curve
value" definition above.) The curve value is shown as a convenience so that you
know what you have to change it back to in order to get back on the actual curve's
table listing. While an "offset" is in effect, the parameter of the curve is still modified
versus time. However, the actual parameter value is the "curve value" modified by
the "offset".
Power Mode
The building is closed up except for Inlets (usually Baffle Doors) which are powered
open and close in order to control the static pressure level. In some cases Gravity
Inlets are used where the static pressure is not controlled directly. The only
ventilation provided is due to Fans mounted in the end or side walls. This mode of
operation generally happens when the outside temperatures are somewhat lower than
the set temperature.

Program
A "program" is a complete set up of all the screens of a Control. In the main menu Program Tab, six
different "programs" can be saved and later activated. This can be very convenient when it is desired to
change the set up at different points during the grow out, barn cycle, or times of the year.
Set Temperature
The set temperature is another very important, basic, concept. All temperatures are referenced to the set
temperature. When the set temperature is adjusted either manually, or because the set temperature curve
is on, all other temperature settings move up or down by the same amount. For instance, even though you
program an actual temperature for each Fan to come on and off, when you change the set temperature,
those Fan's on and off temperatures are adjusted by the same amount
you changed the set temperature.
Spare Temp Sensor
The spare temperature sensor is a temperature sensor that is separate from one of the 12 controlling
sensors. This sensor can be used to control the temperature in a separate area of the house. The sensor has
its own maximum and minimum alarm parameters that can be set up in the Alarms screen. The sensor can
also turn on and off the Spare Temperature Sensor Output. This output functions like a fan output. The
output has lower Off temperature than its On temperature. The On and Off temperatures for the Spare
Temperature Sensor output are defined in the Outputs and Temperatures screen. The spare temperature
sensor can not be used to control any other output.
