Tools for analyzing ventilation performance
Select Ventilation has three main tools for analyzing data.
 Power Block status viewer (below)
 Reports (on page 65)
 Charts (on page 78)
Viewing the status of a Power Block
The Power Block status viewer displays the status of the Power Block’s variable and relay stages. Check
the status viewer regularly and make sure the controls are functioning normally.
Status for PBx Power Blocks
Select Ventilation retrieves the actual status from the Power Block.
Status for PB-1 to PB-6 Power Blocks
Select Ventilation calculates and displays information based on the ambient temperature and
settings.
 For variable stages, the display shows the expected speed of the fan or percentage of output.
 For actuators, the display shows the expected position (percentage open).
 For relays, the display shows the expected state: on, off, or cycling. Cycling is for duty cycle or
curtain relays only; it means the temperature condition has been met and the relay is in an on
duration or off duration.
