Communication with Associated Devices
The controller is capable of communicating and sharing information with other controllers on the network.
Communication with BLM
When associated with the BLM series controllers, the SMZ1 communicates a demand for hot water. For a demand to
be received at the BLM series controller, the SMZ1 must be associated with the BLM and have the
Heat Demand
or
Zone Demand
configuration parameter enabled.
Communication With HPM
When associated with the HPM1 water to water heat pump controller, the SMZ1 communicates a demand for hot
water. For a demand to be received at the HPM1 controller, the SMZ1 must be associated with the HPM1.
Automatic Configuration
The SMZ1 and iWorx® Local Control Interface (LCI) use a self-configuring network management scheme requiring no
external tools, binding, or L

knowledge. The LCI recognizes and configures the SMZ1 when the controller’s
service pin is pressed. The controller’s status light flashes green until the controller is configured, and is solid green
after the controller is configured. Once the service pin has been pressed, no further action is required by the user; the
controller is fully accessible to the LCI. Users may bind to SNVTs on the SMZ1 with LNS or other L
ON
W
ORKS
tools
after
the SMZ1 has been inserted into the LCI2 network.
The LCI also provides network supervision of the SMZ1. The LCI periodically sends a "ping" message to the SMZ1,
which elicits a response. If the response fails, an alarm is displayed on the LCI. The LCI also uses the "ping" message
to refresh the occupancy mode and other system wide data.
