2 Overview
The Systemair Z-Wave Ventilation is a residential heat recovery ventilation system, which consists of the following
main modules:
• Ventilation Unit, which is controlled by a module called PCU-ECx, where ‘x’ is a digit representing the module
generation
• One or more local User Interface/s called CDx, where ‘x’ is a digit representing the module generation. The CDx is
connected to the PCU-ECx. Via CDx the user can control locally the Ventilation Unit.
• Z-Wave to Systemair HVAC Interface Adapter, which connects the Z-Wave network with the Ventilation Unit.
3 Z-Wave coexistence
This Product can be included and operated in any Z-Wave network with other Z-Wave certified devices from other
manufacturers and/or other applications. All non-battery operated nodes within the network will act as repeaters regardless of vendor to increase reliability of the network.
4 Installation
Danger
• All electrical connections must be carried out by an authorized installer and in accordance with local rules
and regulations.
Z-Wave adapter connects a wireless control (gateway) and a residential unit to be able to communicate wireless.
11 Install the residential unit. Remove label that covers a
Modbus connection.
22 Connect Z-Wave adapter to the Modbus connection on
the unit using a provided cable with RJ45 type plugs.
33 Connect the Z-Wave adapter to the power supply.

6 Add device to Z-Wave network — Inclusion
When the device is not added to a Z-Wave network, then triple short clicks of the inclusion button will start the inclusion. The device begins a classic inclusion. If after 3 attempts the inclusion doesn’t succeed, then the Network Wide Inclusion will be started.
7 Remove device from Z-Wave network — Exclusion
When the device is already included in a Z-Wave network, then triple short clicks of the inclusion button will exclude it
from that Z-Wave network.
8 Associations
The Device supports one, the Lifeline Association Group only. Maximum 5 nodes can be added to that group. The device
uses the Lifeline group to send the following unsolicited reports:
• Thermostat Mode Report – when thermostat mode changes,
• Thermostat Setpoint Report – when the temperature setpoint changes,
• Thermostat Fan Mode Report – when the fan level changes,
• Notification Report – when an alarm occurs,
• Switch Binary Report – when the device enter/exit the Boost mode,
• Device Reset Locally – at factory reset
9 Thermostat HVAC and Basic command class
The Systemair Z-Wave Ventilation supports two thermostat modes which are mapped to the Comfort and Energy Saving Mode:

Comfort Mode
Energy Saving Mode
10 Application status
Some of the implemented CCs need to be translated to the Ventilation Unit via the Modbus interface. Due to some reasons that communication couldn’t be available, for example – disconnected/damaged communication cable. In order to
cover such situations, the Application Status Command Class has been implemented.
So, In case of no communication between Z-Wave Adapter and the Ventilation Unit Module, the Device will send “Application Reject Request” for all Z-Wave commands required communication with the Ventilation Unit.
If the Modbus communication is up and running, the device is always available to respond in the specified time, i.e. the
device will never report “Application Busy” command.
11 Temperature setpoint
The device supports “Thermostat Auto changeover” setpoint type only. The setpoint range varies in depend of the ventilation system type (Table 3) and some other ventilation unit configurations. All of these dependencies must be fixed
at inclusion time, so the system will be fully defined. The Host shall retrieve the setpoint range using the Thermostat
Setpoint Capabilities Get V3 command. In additional to the reported Min and Max Values, 0°C is supported as well.
The device accepts the setpoints in a predefined step in the reported range. It is available via the Configuration CC, parameter 5 (see Table 2: Configuration Parameters).
12 Fan mode
The device will support Fan Auto Mode, if both RH and CO2senors are present. This must be done at inclusion time.
The Z-Wave Systemair Ventilation supports following Thermostat Fan Modes:
Thermostat Fan Mode Ventilation Unit Fan
Bit Off Value Mode Mode Level
0 0
1
0 1 Low Low
0 3
0 5
Auto/Auto Low Demand/Automatic
- -
High High
Medium Normal
Manual
Auto
Off
13 Boost Mode
The Systemair Z-Wave Ventilation has implemented a Boost Mode. That mode overrides the selected fan speed, setting
it to a predefined level (usually high) for a predefined time period.
To set the Boost Mode remotely via Z-Wave, the Binary Switch CC is used. But that binary switch is a bit special – Once
it is turned ON, it locks itself in ON position for the predefined time period, and it can’t be turned off until that time period expires.
The Host can use the Ventilation System Boost mode in case of smoke or fire alarm for example.
14 Alarms
The implemented Notification CC V3 is used to report the device malfunctions:
• Notification Type 0x09 – “System”
• Event Type 0x03 – “System Hardware Failure with manufacture proprietary code”
The failures are reported in a two bytes value, where each bit represents a certain alarm. If the bit is set (1) the alarm is
active, and if the bit is cleared (0) the alarm is not active.
| A002
Configuration |
Any bit’s transition from 0 to 1 will trigger an unsolicited Notification Report. The system maintains a repeat timeout
counter for each alarm, which is hard coded to 24 hours. So, an alarm occurrence runs its counter. When the repeat time
expires and the alarm still exists (its bit is set) a new unsolicited Notification Report will be send. A bit’s transition from
1 to 0 clears its repeat counter.
The alarms are generated in the Ventilation Unit.

16 Operational modes and indicators
The Z-Wave Adapter module has 4 operational modes:
• Normal
• Not Included
• Factory Reset
• Firmware Uploading
All operational modes and readiness to enter in a mode are indicated with a two colors LED.
The Z-Wave Adapter operates in Normal mode when it is included in a Z-Wave network and the communication with
the ventilation unit is up and running. That mode is indicated with the following LED pattern (OOnnee ssqquuiirree iiss aabboouutt 00..11ss,,

G G R R
The Z-Wave Adapter is indicating each phase with a different LED pattern – see “Operational modes and indicators”.
At each step the Z-Wave Adapter will wait for a while for the next user action, and then will cancel the Factory Reset
procedure.
During the Factory Reset the device will resets all Z-Wave part. This includes parameter 6 and 7 values as well as the
eventually already downloaded (fully or partially) firmware images for ventilation unit.
After Factory Reset, the Z-Wave Adapter will enter in “Not Included” mode.
16.2 Firmware uploading
When the Z-Wave Adapter has been downloaded a new firmware version for PCU-ECx and/or CDx module/s, it/they
can be uploaded to the Ventilation Unit.
A Firmware Uploading is initiated by a request from the ventilation unit via its local UI. This will start the uploading of
the firmware available in the Z-Wave Adapter to the Ventilation Unit. The led pattern below shows the Firmware Uploading mode is about to be entered:
LLEEDD ppaatttteerrnn 77:: FFiirrmmwwaarree uuppllooaaddiinngg mmooddee rreeaaddyy

The fault condition is terminated when the ventilation unit responses are detected again.
Please Note: To bootload the just uploaded firmware, the Ventilation Unit requires a power cycle.
17 Configuring the unit while device is added to Z-Wave network
It is not allowed to change any of these settings while the device is included in Z-Wave network:
• System type
• Heater type
2
• CO
and RH (relative humidity) sensors
In case settings have to be changed, follow these steps:
1. If the Gateway is present and operational then exclude the device (chapter 7). If device cannot be excluded (in case
of Gateway malfunction, i.e. when the gateway is changed), then Device Reset Locally procedure must be done.
2. Do the necessary changes.
3. Add the device to Z-Wave network again (chapter 6).
