stelpro STZB402+ ELECTRONIC THERMOSTAT FOR THE SMART HOME User Guide Overview

Summary of Contents

• Page 1: User's guide for the STZB402+ electronic thermostat for the smart home. For further information or to consult this guide online, please visit our website.
• Page 2: Before installing and operating this product, the owner and/or installer must read, understand and follow these instructions and keep them handy for future reference. If these instructions are not followed, the warranty will be considered null and void. All electric connections must be made by a qualified electrician, according to the electric and building codes effective in your region. Do not connect this product to a supply source other than 120 VAC or 240 VAC, and do not exceed the load limits specified. You must regularly clean dirt accumulations on the thermostat. Do not use fluid to clean thermostat air vent. When a part of the product specification must be changed to improve operability or other functions, priority is given to the product specification itself. The actual product and packaging, as well as the name and illustration, may differ from the manual. The screen/LCD display shown as an example in this manual may be different from the actual screen/LCD display.
• Page 3: This thermostat is designed to control baseboard, convector and fan-forced heaters. It may be associated to a ZigBee network. This thermostat is not compatible with inductive load, central heating systems, or heating loads outside the specified ratings. 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. Do not install the thermostat in a location where temperature measurements could be altered, such as close to a window, on an external wall, or close to a door leading outside.
• Page 4: Thermostat mounting and connection Cut off power supply on lead wires at the electrical panel to avoid any risk of electric shock. If an existing thermostat is being replaced, remove the previous thermostat. Ensure that the air vents of the Ki thermostat are clean and clear of any obstruction. Using a screwdriver, loosen the screw retaining the mounting base of the thermostat. Remove the mounting base at the back of the thermostat by tilting it downward, then towards you. Align and secure the mounting base to the connection box using the two screws supplied.
• Page 5: Pass the wires from the wall through the hole at the base of the mounting base and connect them using the solderless connectors supplied. When making the connection with aluminum wire, make sure that you are using connectors identified CO/ALR. The thermostat wires do not have polarity. Therefore, the way they are connected is not important.
• Page 6: Place all the wires into the connection box. Align the little slots located on the top of the thermostat with those on the mounting base and secure the thermostat to the mounting base. You can also position the thermostat on the left or the right side of the junction box. Tighten the screw at the bottom of the unit. Turn the power on.
• Page 7: Operation Ambient temperature ZigBee connectivity Heating status Lock mode Fan mode Frost warning Advanced settings Thermostat mode Set point temperature or outdoor temperature
• Page 8: Ambient temperature is displayed in °C or °F. The screen shows LO for temperatures below 0 °C and HI for temperatures above 50 °C. Users can edit the temperature setpoint using UP and DOWN buttons on the thermostat. The minimum setpoint is 5 °C and the maximum is 30 °C. A frost warning icon appears if the setpoint is 7 °C or below. The heating power indicator shows the heating percentage with a bar graph. The thermostat has three modes: Comfort, Eco, and Off. Comfort mode is set to 21 °C and Eco mode to 17 °C. The Eco setpoint is local to the thermostat and cannot be edited through the ZigBee network. Changing the setpoint via ZigBee will switch the thermostat to Comfort mode.
• Page 9: Even in Off mode, the thermostat is still powered and electric shock is still possible. Always cut off the power supply when cleaning or removing the thermostat. When in Off mode, the thermostat will not activate the heating element, therefore there is a risk of freezing. The thermostat has two heating modes: Baseboard/convector heater and Fan-forced heater. The Baseboard/convector heater mode will drive the load with a 15-second cycle while the Fan-forced heater mode will drive the load with a 5-minute cycle. If the thermostat is associated to a ZigBee network, the connectivity icon will be displayed on the LCD. If the device is removed from a ZigBee network, the connectivity icon will disappear. There are 7 advanced settings menus on the thermostat. The advanced settings include ZigBee menu, display format, heating mode, lock mode, outdoor temperature display, and backlight status while idle.
• Page 10: STELPRO information menu: used to gain information on the product. Thermostat version. ZigBee radio version. Day of production. Month of production. Year of production. Baseboard/convector control checksum. Fan-forced heater control checksum. To gain access to the advanced settings root menu, press the UP and DOWN buttons simultaneously for 3 seconds. To associate the thermostat to a ZigBee network, enter Menu 1 (ZigBee menu) and either select (On) or the specific ZigBee channel used by your ZigBee controller.
• Page 11: Disassociation: To remove the thermostat from the ZigBee network, enter Menu 1 (ZigBee menu) and select (Off). Press the UP and DOWN buttons to start the disassociation process. During disassociation, (Off) will be blinking and the connectivity icon will be animated in a decreasing pattern. When the disassociation process has been completed, (Off) will be displayed solid. If an error occurs, (Err) will be displayed for 3 seconds then the screen will revert to the associated ZigBee channel. It is recommended to always associate your ZigBee 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 from the ZigBee network. To reset the thermostat to its default settings, enter the advanced settings, enter the °STELPRO menu (menu 7), navigate to the (def) screen using the UP or DOWN buttons, enter the (def) menu by pressing the UP and DOWN buttons for less than 3 seconds, select (yes) and confirm the selection by pressing the UP and DOWN buttons for less than 3 seconds. The thermostat will then reset itself. Power Outage: If a power outage occurs, the thermostat will stop working but all configuration is saved. Outdoor Temperature: When connected to a ZigBee network, the thermostat may display the outdoor temperature provided by an external sensor. When available, the outdoor temperature is displayed instead of the setpoint, provided 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. An external sensor needs to be part of the ZigBee network to display the outdoor temperature.
• Page 12: Refer to your ZigBee controller instructions manual to find how to associate both devices. On some ZigBee controllers, an app may be used to provide the outdoor temperature. 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 ZigBee network. Make sure the thermostat is within range of the ZigBee controller or a ZigBee repeater. Secondary temperature sensor is defective. The thermostat will still control the temperature but performance may be diminished. Consider replacing the thermostat.
• Page 13: Problem: The thermostat is hot. Solution: In normal operating conditions, the thermostat housing may become hot at maximum load. Heating is always on. Check if the thermostat is properly connected. Heating does not run even if the thermostat indicates it is on. Check if the thermostat is properly connected. The display does not turn on. Check the power supply at the electrical panel. The display turns off a few minutes and then turns on again. Check the presence of an air stream or a heat source near the thermostat. The displayed ambient temperature is incorrect. Make sure the heating mode is set to Fan. There is an issue with the ZigBee radio. Reinitialize the thermostat. Setpoint and mode cannot be changed. The thermostat is locked, turn OFF the lock mode. If you are unable to solve the problem after having verified these points, please communicate with customer service.
