Configuring relays for timed events
Relays configured for timed events can be used to switch lights on and off or control equipment that
must operate at specific times each day, regardless of temperature.
An event is a switch from on to off, or from off to on. For example, switching the yard lights on at 8:00
PM and off at 7:00 AM is two events.
Configuring relays for timed events means selecting the timed event function and entering a
descriptive name.
 Use the Installation and configuration worksheets when configuring Power Blocks.
The worksheets are in the back of the Power Block installation guide.
 For more information about timed events, read Programming timed events on
page 59.
 Each PBx Power Block can store up to 250 events, no matter how many relays
are configured.
 Timed events for PBx Power Blocks are stored on the Power Block and do not
rely on the software for timing. This means the timed events will function even if
there is no communication with the software.
 Timed events for PB-1 to PB-6 Power Blocks are stored in the software. This
means timed events will function only if there is communication with the
software.

1. In the main window, click Configuration, and then Ventilation.
2. Below Your Power Blocks, select the Power Block you want to configure and then click Configure
Power Block.
