LPower connection (Live) 230VAC.
S2 Switch 2 is used as a scene controller.
NB! In toggle mode, S2 must not be connected.
S1 Switch 1. Used to control the internal relay.
6. CONTROL
The device features a configuration button and an LED indicator.
7. ADD/REMOVE
Please read this before installation
The primary controller/gateway has a mode for adding or removing
devices. Please refer to your primary controller manual on how to set
the primary controller in add/remove mode. The device may only be
added or removed from the network if the primary controller is in add/
remove mode.
When the device is removed from the network, it will NOT revert to
factory settings.
There are two ways to add the device to a Z-Wave network.
7.1 Method 1: Standard (Manual)
Add/remove mode is indicated on the device by a blinking green LED.
This lasts until timeout occurs after 90 seconds, or until the module has
been added to/removed from the network.
The LED will light up for 3 seconds if adding/removing is successful.
The device is now ready for use with default settings.
If adding/removing fails, the LED will light up in red for 3 seconds.
NB! When the device is removed from the gateway, the parameters are
not reset. To reset the parameters, see Chapter 8 ”Factory reset”.
If inclusion fails, please perform a ”remove device” process and try again.
If the LED lights up in red again, please see Chapter 8“Factory reset”.
7.2 Method 2: SmartStart (Automatic)
SmartStart enabled products may be added to a Z-Wave network
by scanning the Z-Wave QR-Code on the product if your primary
controller supports SmartStart inclusion. No further action is required
and the SmartStart product will be added automatically after being
powered on within range of the primary controller.
8. FACTORY RESET
Press and hold the configuration button. After 3 seconds the LED will start to
blink in green. After 20 seconds the LED will stop blinking and emit a constant
light. You may now release the button.
NB! Please use this procedure only when the primary controller/
gateway is missing or otherwise inoperable.
9. STARTUP
After powering up the device for the first time, all the parameters will have
default settings.
10. SAFETY FEATURES
The device security features make the device safe to use and notifies the user
of any unexpected behavior in the device, such as overload or overheating.
If this happens, the relay cuts power to prevent failure.
Heatit ZM Single Relay 16A has the following features:
10.1 Overload
The device features a default 16A overload protection. The default overload
is triggered if there is a power draw of more than16Amps for longer than
2 seconds, or 0.2 seconds if the measured load is more than 20A. When a
current higher than 16Amps has been detected, the connected load must be
checked. It is not possible to turn the relay back on until a powercycle has been
performed. This prevents unwanted power cuts that may be caused by inrush
currents. The user may define a specific user cutoff according to need using
Parameter 1.
When an overload is detected, the device will:
• Set the relay in OFF-state when triggered and send a binary switch
report representing relay state
• Send Notification (Overload detected)
To clear the overload state, the relay must be switched back on
manually using Z-Wave or connected switch. When the realy state
has been changed and overload is no longer triggered, the device
will send a Notification (Overload idle). Parameter 2 can be set to
automatically retry at regular intervals. This Parameter 2 setting will
only work if the overload was triggered by a user-specific load limit
(Parameter 1).

13. QR-CODE PLACEMENT (DSK)
The QR-Code is needed when including a device using S2 security or
SmartStart. The DSK can be found in the QR-Code and is located;
1. On the product.
2. On the Quick Guide manual.
3. On the product box.
14. SECURITY
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. This device
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.
15. 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.
16. 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.
16.1 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.
10.2 Overheating
The device features an internal temperature sensor which prevents any
overheating caused by external high loads.
When overheating is detected, the device will:
• Set the relay in OFF-state when triggered and send a binary switch
report representing relay state
• Send Notification (Overheating detected)
To clear the overheating state, the relay must be switched back on
manually using Z-Wave or connected switch. When the relay state
has been changed and temperature stabilized, the device will send a
Notification (Overheating idle). Parameter 2 can be set to automatically
retry at regular intervals.
11. SWITCH MODE
The device supports two types of switches, momentary and toggle
switch. The device uses momentary switches by default.
11.1 Momentary Switch (NO) – Default
This is the recommended mode which allows for the use of all features.
When used as a momentary switch, the device supports the HOLD
and RELEASE functions for central scene and association groups.
The switch must be a normally open switch.
11.2 Toggle Switch (ON/OFF)
In toggle mode, the device relay and switch state will not always be
equal as the user can control using other Z-Wave devices.
When using the device in toggle switch mode, the device will lose the
following functionality:
• Inclusion using S1
• Scene Controller Commands
• Association Group 3 and 5, Multilevel Switch (level increase/decrease)
The toggle switch will not always turn ON when the output of switch
is HIGH because the relay may also be controlled externally using the
Z-Wave protocol.
NB! When using toggle switch, S2 must not be connected in
order to ensure correct functionality.
12. LED BLINKING PATTERNS DESCRIPTION
The device support numerous LED blinking patterns to make it as easy
as possible to identify the issue.
