What you need to know before programming
Power Blocks
The difference between configuring and programming Power Blocks is that configuring is telling
Select Ventilation what equipment is connected to each stage or relay, while programming is telling
the software how to control it.
To simplify things, we can divide the programming settings into two groups: Power Block settings and
equipment settings.
 Power Block settings apply to everything the Power Block does and controls (in other words, all
the equipment connected to it). Power Block settings include the master set point, alarm
settings, growth curves, and temperature setbacks.
For more information, read Programming Power Block settings on page 31.
 Equipment settings apply to the specific equipment type. For example, the actuator 1 settings
apply only to actuator 1. Equipment settings include settings for variable stages, actuators,
curtains, relays and timed events.
For more information, read Programming equipment settings on page 45.
