Setting the Hydronic Zone for Controllers
To associate a DXU4 to a BZU, you start from the BZU control screen. Press Members to display a list of the DXU
units on the network. The member status of each is shown in the right-hand column. A member unit is one that oper-
ates with shared settings from the BZU. To change the member status of a DXU controller, just press that controller. It
will toggle member or non-member with each press. If a DXU has been selected or deselected, you must press
Save
afterward to comfirm the new setting.
If no Hydronic Zone is selected, the DXU4 uses the zone temperature sensor to which it is connected.
DXU3 / DXU4
What it does:
The DXUx controller is used to stage heating and cooling to satisfy the space demands. The DXU4 can also be config-
ured to share temperature readings with a BZU controller.
NOTE: When the DXU is associated to a BZU, the heating setpoint can only be set in the DXUx controller;
the setting will be sent to the BZU controller automatically!
