11. CHILD LOCK - LOC
By pressing Left and Right (down and up buttons for 10 seconds,
the thermostat will display LOC. Child lock is now activated, and the lock
icon will be lit up when the display is active. Trying to make changes from
the display is not possible within this modus. Changes with the Z-Wave
controller is still possible. Refer to your primary controller/gateways user
manual on how to change the setpoint.
Child lock is deactivated by pressing Left and Right (down and up)
buttons for 10 seconds, the thermostat will display oPn. The lock symbol
is no longer lit when the display is active, and now you can make changes
using buttons.
12. INVERTED OUTPUT
The thermostat can invert its signal sent to external relays. This allows
users to use the Heatit Z-TEMP2 together with other systems. You can
change this behaviour using a quick feature in the thermostat or, using
Parameter 15 “Inverted Output”.
Changing the behaviour,
• From physical device by holding centre and right button for 10 sec.
• From gateway by changing parameter 15 (for more information
regarding the configuration parameter, see chapter “Configuration
Parameters”).
The thermostat will display “HEA” for regular operation, and “COO” for
inverted operation. You can check what mode you are using by holding
centre button for 10 seconds.
13. STANDBY AND MAIN SCREEN
When the thermostat remains untouched for a while, it will
automatically go to standby screen. Due to power saving settings, while
in standby, the display will be turned off. The proximity sensor will activate
the thermostat when proximity is sensed. You can also activate the
thermostat manually by pressing any button.
14. Z-WAVE QR-CODE / DSK
The QR Code is needed when including using S2-Security or
SmartStart. The Z-Wave DSK can be found in the QR-Code and is
located;
1. On the back of wall mount (above the battery compartment).
2. Inside the packaging attached on the note.
3. On the product packaging.
15. SECURITY
The S2 security enhances Z-Wave Plus with an additional layer of AES 128-
bit encryption of the wireless Z-Wave communication to prevent hacking
and man-in-middle attacks on the home network. The Heatit Z-Temp2
supports S2 and has a Z-Wave DSK QR-Code label that may be used when
the module is added to the Z-Wave home network. The primary controller
will ask for a 5-digit Code, which can be found underneath the QR-Code.
The primary controller will then ask you to confirm the rest of the code
that is contained in the QR-Code.
16. NODE INFORMATION FRAME
The node information frame is the business card of a Z-Wave device.
It contains information about the device type and its technical features.
The add and remove procedure of the device is confirmed by sending
out a node information frame. Besides this, it may be necessary for certain
network operations to send out a node information frame.
17. ASSOCIATIONS
Z-Wave devices interact with other Z-Wave devices. The relationship
between one device controlling another device is called an association.
In order to control a subordinate device, the controlling device needs to
maintain a list of devices that will receive controlling commands. These
lists are called ”Association Groups”. They are always related to the specific
event triggered (e.g., sensor reports). In case the event is triggered, all
devices stored in the respective association group will receive a joint
wireless command.
SETTING AND REMOVING ASSOCIATIONS
Associations may be assigned and removed via Z-Wave commands.
Please refer to your primary controller/Z-Wave gateway for more
information.
