THE THERMOSTAT MUST BE INSTALLED BY A CERTIFIED ELECTRICIAN.
Connect the thermostat to a 120 to 240 VAC power source ONLY and comply with load limits.
WARNING – HIGH VOLTAGE. Turn off the power supply before installation and maintenance. Leave at least 12 in. (30 cm) clearance around the thermostat to ensure that it is properly vented.
SAVE THESE INSTRUCTIONS
This thermostat is designed to control the baseboard and convector. It may be added (included) in a Z-Wave network.
THIS THERMOSTAT IS NOT COMPATIBLE WITH THE FOLLOWING INSTALLATIONS
PARTS SUPPLIED
The thermostat must be mounted to a connection box on a wall facing the heating unit, at around 1.5 m (5 feet) above the floor level, on a section of the wall exempt from pipes or air ducts.
Do not install the thermostat in a location where temperature measurements could be altered. For example:
ATTACH THE THERMOSTAT
AMBIENT TEMPERATURE
The temperature is displayed either in °C with a 0.5 °C resolution or in °F with a 1 °F resolution. The screen will display LO if the temperature drops below 0 °C (32 °F) and will display HI if the temperature rises above 50 °C (122 °F).
TEMPERATURE SETPOINTS
The setpoint may be edited by the user using the UP and DOWN buttons located on the thermostat. The setpoint may also be modified through the Z-Wave network.
The minimum setpoint is 5 °C (41 °F) and the maximum setpoint is 30 °C (86 °F).
NOTE: if the setpoint is set at 7 °C (45 °F) or below, the frost warning icon
HEATING POWER INDICATOR
Whenever the thermostat is actively heating the room, the heating status graph will display the heating percentage.
THERMOSTAT MODE
The thermostat has three modes: Comfort, Eco and Off. The first two modes have their own preestablished setpoint. Comfort: 21 °C (70 °F), Eco (
The user may change the setpoint to any value in the range described in the setpoint section. When the Eco mode is active, the Eco icon (
Z-WAVE CONNECTIVITY (
If the thermostat is added (included) to a Z-Wave network, the connectivity icon
ADVANCED SETTINGS (
There are 6 advanced settings menus on the thermostat.
The advanced settings are the following:
MODIFICATION OF THE SETTINGS:
Z-WAVE INCLUSION/EXCLUSION (
INCLUSION:
Make sure the Z-Wave hub is in the include mode (refer to your Z-Wave hub instruction manual).
To add (include) the thermostat to a Z-Wave network, enter Menu 1 (Z-Wave menu) and select (On). Then press the UP and DOWN buttons to start the inclusion process. During inclusion, (On) will be blinking and the connectivity icon
EXCLUSION:
Make sure the Z-Wave hub is in the exclude mode (refer to your Z-Wave hub instruction manual).
To remove (exclude) the thermostat from a Z-Wave network, enter Menu1 (Z-Wave menu) and select (Off). Then press the UP and DOWN buttons to start the exclusion process. During exclusion, (Off) will be blinking and the connectivity icon
To achieve better network performance, it is recommended to always add (include) your Z-Wave devices starting from the closest one to the farthest one.
FACTORY RESET
The thermostat may be manually reset to its original factory settings.
When this is performed, all parameters are reset to their default values and the thermostat is removed (excluded) from the Z-Wave network.
To reset the thermostat to its default settings:
If the thermostat was added (included) in a Z-Wave network, it will send a (device reset locally) notification.
The thermostat will then reset itself.
Please use this procedure only when the network primary controller is missing or otherwise inoperable.
POWER OUTAGE
If a power outage occurs, the thermostat will stop working but all configuration is saved.
OUTDOOR TEMPERATURE (
When connected to a Z-Wave network, the thermostat may display the outdoor temperature provided by an external sensor.
When available, the outdoor temperature is displayed instead of the setpoint, providing that the outdoor temperature display setting is set to (On). If no temperature is received within a 4-hour timeframe, the outdoor temperature will disappear and the setpoint will be displayed. In order to display the outdoor temperature, an external sensor needs to be part of the Z-Wave network. It may be a physical sensor or a weather station app. Refer to your Z-Wave hub controller instructions manual to find how to associate both devices. On some Z-Wave hub controllers, an app may be used to provide the outdoor temperature.
PROBLEM CODE | DEFINITION |
LO | Temperature is below 0 °C (32 °F), heating will be always active |
HI | Temperature is above 50 °C (122 °F), heating will be always inactive |
— | Temperature sensor is defective, heating will always be inactive. Call technical support. |
ERR | The connection could not be established with the Z-Wave network. Make sure the thermostat is within range of the Z-Wave controller or a Z-Wave repeater and make sure the Z-Wave controller is in inclusion or exclusion mode. |
E1 | Secondary temperature sensor is defective. The thermostat will still control the temperature but performance may be diminished. Consider replacing the thermostat. |
PROBLEM | SOLUTION |
The thermostat is hot | In normal operating conditions, the thermostat housing may become hot at maximum load. That is normal and will not affect the effective operation of the thermostat. |
Heating is always on | Check if the thermostat is properly connected. Refer to the installation section. |
Heating does not run even if the thermostat indicates it is on | Check if the thermostat is properly connected. Refer to the installation section. |
The display does not turn on | Check if the thermostat is properly connected. Refer to the installation section.Check the power supply at the electrical panel. Check if the heating unit has a switch. If so, ensure that this switch is turned on. |
The display turns off a few min- utes and then turns on again | The thermal protection of the heating unit has opened due to overheating. Check if the heating unit is in good oper- ating condition and that clearance around the appliance is according to the manufacturer’s specifications. |
The displayed ambient temperature is incorrect | Check the presence of an air stream or a heat source near the thermostat, and correct the situation. |
The connectivity icon | Make sure the thermostat is properly associated with the Z-Wave controller. |
Setpoint and mode cannot be changed | The thermostat is locked, turn OFF the lock mode |

Z-WAVE INTEROPERABILITY
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.
Z-WAVE ASSOCIATION
The Z-Wave Association Command Class is supported by the thermostat.
The thermostat supports the lifeline as Group1 and only one Node Id is supported in this group (the Z-Wave controller).
The following reports are sent via the Lifeline:
Z-WAVE BASIC COMMAND CLASS
The Z-Wave Basic command class is supported by the thermostat in the following way:
To trigger the Eco mode on the thermostat: send it a Basic SET (0x00) command (Energy saving mode). To trigger the Comfort mode on the thermostat: send it a Basic SET (0xFF) command (Comfort mode)
If a setpoint change is sent through the Z-Wave network, the thermostat mode will automatically switch to Comfort mode. The Z-Wave modes are described in the following table:
