Connection
1. DZK connection bus
The DZK connection bus allows the connection of up to 6 Wired
Thermostats. There are 3 connectors, each one with 5 contacts
available, for connecting the expansion bus. The Wired Thermostat
is connected to the DZK bus (Maximum of 2 Wired Thermostats per
connector).
Connect the cables to the connector contacts following the color
code indicated below.
2. Wireless interface
This device provides the communication between the Zoning box
control board and Wireless Thermostats and Wireless Lite
Thermostats.
3. Reset system button
If the whole system needs to be reset (normally a replacement board
that has been used before, or at the request of the technical support
as a last resource to fix a problem), press and hold SW1 until LED 19
stops flashing. A system reset will return all settings to default values
and conditions.
Important:
At least one Wired
Thermostat is required for each
DZK system, which can control up
6 zones.
Keep in mind: once this
sequence is started it cannot be
interrupted and the Quick Setup
process should be allowed to
finish.
