Programming the master set point
The master set point is the desired or target temperature for the room or zone. Make sure you
program the master set point before programming the equipment set points. If you adjust the
master set point, Select Ventilation adjusts the set points for each variable and relay stage relative to
the master set point.
For example, the master set point for zone 1 is 80°F, a variable-stage fan set point is 85°F, and a
single-stage heater set point is 73°F. If you lower the master set point by 5 degrees to 75°F, Select
Ventilation lowers the set points for the fan and heater by 5 degrees to 80°F and 68°F respectively.
Use the Master settings worksheet on page 82 when programming Power Block
settings.
You cannot manually adjust the master set point if the master set point curve is
enabled. For more information, read Programming ventilation curves on page 35.
