SUPPLY WIRES  

If the thermostat is added (included) to a Z-Wave network, the  

connectivity icon will be displayed on the LCD, if the device is  

removed (excluded) from a Z-Wave network, the connectivity icon  

will disappear. The connectivity icon may blink if there is an issue  

with the Z-Wave radio circuit.

1. Pass the wires from the wall through the hole at the base of the  

mounting base and connect them using the solderless con-  

nectors supplied. When making the connection with aluminum  

wire, make sure that you are using connectors identified CO/  

ALR. Please note that the thermostat wires do not have polari-  

ty. Therefore, the way they are connected is not important.

sensor over Z-Wave)  

The thermostat must be mounted to a connection box on a wall fac-  

ing 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 mea-  

surements could be altered. For example:  

FACTORY RESET  

The thermostat may be manually reset to its original factory set-  

tings.  

• close to a window, on an external wall, or close to a door leading  

outside  

• exposed directly to the light or heat of the sun, a lamp, a fireplace  

or any other heat source  

When this is performed, all parameters are reset to their default  

values and the thermostat is removed (excluded) from the Z-Wave  

network.  

• close to or in front of an air outlet  

• close to concealed ducts or a chimney  

To reset the thermostat to its default settings:  

1. Enter the advanced settings  

FONCTIONS  

• in a location with poor air flow (e.g. behind a door) or with frequent  

air drafts (e.g. head of stairs)  

2. Enter the °STELPRO menu (menu 6)  

AMBIENT TEMPERATURE  

3. Navigate to the (def) screen using the UP or DOWN buttons.  

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 tem-  

perature drops below 0 °C (32 °F) and will display HI if the tempera-  

ture rises above 50 °C (122 °F).  

4. Enter the (def) menu by pressing the UP and DOWN buttons for  

less than 3 seconds  

ATTACH THE MOUNTING PLATE

5. Select (yes) and confirm the selection by pressing the UP and  

DOWN buttons for less than 3 seconds.  

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 modi-  

fied through the Z-Wave network.  

1.  

Cut off power supply on lead wires at the electrical panel  

in order to avoid any risk of electric shock.  

If the thermostat was added (included) in a Z-Wave network, it will  

send a (device reset locally) notification.  

2. If an existing thermostat is being replaced, remove the previ-  

ous thermostat.  

The thermostat will then reset itself.  

The minimum setpoint is 5 °C (41 °F) and the maximum setpoint is  

30 °C (86 °F).  

Please use this procedure only when the network primary controller  

is missing or otherwise inoperable.  

3. Ensure that the air vents of the Ki thermostat are clean and  

clear of any obstruction.  

NOTE: if the setpoint is set at 7 °C (45 °F) or below, the frost warning  

icon will be displayed to warn the user that water pipes might be  

subject to freezing.  

POWER OUTAGE  

4. Using a screwdriver, loosen the screw retaining the mounting  

base of the thermostat (do not completely remove the screw).  

If a power outage occurs, the thermostat will stop working but all  

configuration is saved.  

HEATING POWER INDICATOR  

OUTDOOR TEMPERATURE (  

)

Whenever the thermostat is actively heating the room, the heating  

status graph will display the heating percentage.  

When connected to a Z-Wave network, the thermostat may display  

the outdoor temperature provided by an external sensor.  

0 bar : 0%  

1 bar : 1-25%  

2 bars : 26-50%  

3 bars : 51-75%  

4 bars : 76-100%  

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.  

THERMOSTAT MODE  

Then, remove the mounting base at the back of the thermostat  

by tilting it downward, then towards you.  

The thermostat has three modes: Comfort, Eco and Off. The first  

two modes have their own preestablished setpoint. Comfort: 21 °C  

In order to display the outdoor temperature, an external sensor  

needs to be part of the Z-Wave network. It may be a physical sen-  

sor or a weather station app.  

(70 °F), Eco (  

The user may change the setpoint to any value in the range de-  

scribed in the setpoint section.  

When the Eco mode is active, the Eco icon (

): 17 °C (63 °F).  

5. Align and secure the mounting base to the connection box  

using the two screws supplied.  

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.  

) is displayed on  

The thermostat mode may be changed locally on the thermostat by  

pressing the UP and DOWN buttons simultaneously for less than 3  

seconds while on the main screen. The Eco setpoint is local to the  

thermostat and cannot be edited through the Z-Wave network.

STELPRO STZW402+ Electronic Thermostat Owner’s Manual Overview

Summary of Contents

• Page 1: Z-Wave connectivity will be displayed on the LCD when the thermostat is added to a Z-Wave network. The thermostat wires do not have polarity, so the way they are connected is not important. There are 6 advanced settings menus on the thermostat, including Z-Wave menu, display format, lock mode, outdoor temperature display, backlight status, and °STELPRO information menu. The thermostat must be installed by a certified electrician and connected to a 120 to 240 VAC power source. To gain access to the advanced settings root menu, press the UP and DOWN buttons simultaneously for 3 seconds. The thermostat may be manually reset to its original factory settings. The minimum setpoint is 5 °C (41 °F) and the maximum setpoint is 30 °C (86 °F). Whenever the thermostat is actively heating the room, the heating status graph will display the heating percentage. The thermostat has three modes: Comfort, Eco, and Off, with preestablished setpoints for each mode. To display the outdoor temperature, an external sensor needs to be part of the Z-Wave network.
• Page 2: Troubleshooting Temperature is below 0 °C (32 °F), heating will be always active. Temperature is above 50 °C (122 °F), heating will be always inactive. Temperature sensor is defective, heating will always be inactive. The connection could not be established with the Z-Wave network. Secondary temperature sensor is defective. In normal operating conditions, the thermostat housing may become hot at maximum load. Check if the thermostat is properly connected. The display does not turn on. Check the presence of an air stream or a heat source near the thermostat. This product can be included and operated in any Z-Wave network with other Z-Wave certified devices.
