I/O Linc Output Relay Mode” or 2) “Resetting the I/O Linc to its
Factory Default Settings”
II. Programming the SmartHome I/O Linc.
This can get a little more complicated. The I/O linc contains two main
functions. First it can be used to interface a sensor, which could be a
simple as a switch, to other devices such as the ValveSentry. For the
application we are working on there is no need to use the sensor
capabilities of the I/O Linc. However, you may think of creative ways
to use the capability. You will need to study the proper sections of
the Insteon I/O Linc’s Owner Manual to use this capability.
The I/O Linc can also be used to convert signals from the power line
to control other devices such as the ValveSentry. This is
accomplished by using the I/O Linc’s relay. This is the functionality
that is being used for this application.
The I/O Linc’s relay can be programmed to work in a number of ways.
See the section “Setting the I/O Linc Output Relay Mode” for
information regarding this.
The factory setting is in the latching mode. As stated before this
mode is required to link the Leak Detectors to the I/O Linc.
The I/O Linc will operate the ValveSentry in this mode. However, if
the ValveSentry is commanded to close the valve, you will need to
push the “Set” button on the I/O Linc to open the relay (LED turns
dim) before pushing the “Open” button on the ValveSentry to open
the valve. You can avoid the need to reset the I/O Linc’s relay to the
open state manually by setting the relay mode to Momentary A using
the instructions to do so “Setting the I/O Lync Output Relay Mode”.
The Momentary A position will close the relay for 2 sec, which should
be enough to trigger the ValveSentry, then reset the relay to the
open position. Two seconds should work fine but if it does not you
