Installers manual  

Heatit Z-Temp3 is a battery-operated thermostat designed for  

controlling waterbased heating systems. Used in combination  

with the Heatit Z-Water2, you can control your heating system  

through the Z-Wave^® network or via the buttons on the front  

panel. The thermostat has a user-friendly interface.

Heatit Z-Temp3 has 3 modes: Heat, Cool, and Eco.  

The thermostat fits into System 55 frames, and may be  

mounted alongside other equipment such as e.g dimmers or  

light switches. Heatit Z-Temp3 can also be mounted directly  

on the wall or placed freely, e.g. on a shelf.  

Heatit Z-Temp3 can be set as a master thermostat. This means  

that you can set the setpoint and mode on one unit, and it will  

automatically send the setpoint and mode to other connected  

units.

All communication between Heatit Z-Temp3 and the  

controlled device is 100% wireless.  

Heatit Z-Temp3 uses 2x AAA batteries, but you can also  

connect the device to an external power source. The  

Heatit Transformer 230VAC (45 126 48) is recommended for  

this purpose.

Product info  

Please read this before installation  

This device may be used with all devices certified with the  

Z-Wave Plus^® certificate and should be compatible with  

such devices produced by any manufacturer. Every primary  

controller is different depending on the manufacturer, their  

target audience and intended use/application. Please review  

the functionalities implemented by the primary controller you  

intend to use with our Z-Wave Plus certified device to ensure  

that it provides the necessary controls to take full advantage of  

our product’s capabilities.

3. BEHAVIOR WITHIN THE Z-WAVE NETWORK  

This device may be operated within any Z-Wave^® network  

with Z-Wave-certified devices from other manufacturers. All  

non-battery-operated nodes within the network will act as  

repeaters regardless of manufacturer to increase the reliability  

of the network. On delivery, the device does not belong to any  

Z-Wave network. The device needs to be added to an existing  

network to communicate with the other devices within it.  

Devices may also be removed from a network. The add/  

remove processes are initiated by the primary controller of the  

Z-Wave network.

HEATIT Z-Temp3 is a Battery Operated Thermostat Instruction Manual Overview

Summary of Contents

• Page 1: INTRODUCTION Heatit Z-Temp3 is a battery-operated thermostat designed for controlling water-based heating systems. The thermostat has a user-friendly interface. Heatit Z-Temp3 has 3 modes: Heat, Cool, and Eco. All communication between Heatit Z-Temp3 and the controlled device is 100% wireless. Heatit Z-Temp3 uses 2x AAA batteries, but you can also connect the device to an external power source. Heatit Z-Temp3 can be associated with other Z-Wave devices to control other types of heating solutions. Heatit Z-Temp3 is a great choice for the restoration or renovation of existing buildings, as it is easy to install without the need for wiring. This device may be used with all devices certified with the Z-Wave Plus certificate. The device needs to be added to an existing network to communicate with the other devices within it. Devices may also be removed from a network.
• Page 2: Quick start instructions for adding the device within a 2 meter range from the gateway can minimize faults during the interview process. Insert the batteries or connect the supplied cable with the Heatit Transformer 230VAC. The Heatit Z-Temp3 does not stay in learn mode until it is included. Mount the device directly on the wall or on a junction box. There are two ways to add the device to a Z-Wave network. Method 1: Standard (Manual) add/remove mode is indicated on the device by rotating LCD segments on the display. Method 2: SmartStart (Automatic) allows products to be added to a Z-Wave network by scanning the Z-Wave QR-Code if your primary controller supports SmartStart inclusion. The thermostat offers versatile installation options, allowing it to be mounted on a wall, on a junction box, or placed at a preferred location. To perform a factory reset, enter the menu by holding the Center button for about 5 seconds and navigate to FACT. The primary controller/gateway has a mode for adding or removing devices, and the device may only be added or removed if the primary controller is in add/remove mode.
• Page 3: Calibration allows for minor adjustments to the temperature readout, which can be calibrated by 6°C using Parameter 4. The thermostat regulates temperature using readings from the internal sensor and can operate in hysteresis or PWM modes based on the setpoint temperature. Brightness of the display can be adjusted using the menu choice “BR1” or Parameter 9. Hysteresis values can be set between 0.3°C and 3.0°C using Parameter 7, with a default setting of 0.5°C. The display ON/OFF function can be enabled or disabled by holding the Left and Center buttons for 10 seconds. With PWM regulation, the thermostat operates based on duty cycles, turning on and off in percentage intervals. To enter the local settings menu, hold the Center button for 5 seconds, allowing navigation through options and submenus. The child lock function disables buttons on the display to prevent local access, indicated by “LOCK” when enabled. Open Window Detection reduces the thermostat setpoint upon detecting a rapid temperature drop from an open window. The temperature shown in standby can be altered with Parameter 8, allowing selection between setpoint and real-time temperature displays.
• Page 4: Error codes include various internal errors and Z-Wave errors, indicating potential issues with the unit. The QR-Code is essential for including a device using S2 security or SmartStart, containing the DSK for device addition. S2 security provides an additional layer of AES 128-bit encryption for Z-Wave communication to enhance security against hacking. The node information frame serves as the business card of a Z-Wave device, detailing its type and technical features. Associations allow Z-Wave devices to control one another, with specific groups for managing commands based on triggered events. Configuration parameters can alter device functionality to better meet user needs, although some parameters are read-only. The thermostat can control multiple relays, but only specific relays should be used for certain applications. Associations can be set and removed via Z-Wave commands, requiring reference to the primary controller for guidance. Temperature limits can be configured, allowing users to set minimum and maximum thresholds for thermostat operation. The display settings can be adjusted for brightness and what information is shown during standby, enhancing user interaction.
• Page 5: Thermostat Mode Command Class allows changing the operating mode of the thermostat. The accessible operating modes include OFF, Heating Mode, Cooling Mode, and ECO Mode. Temperature report interval can be set between 150 to 65535 seconds, with a default of 990 seconds. Humidity report interval is also adjustable from 150 to 65535 seconds, with a default of 990 seconds. The thermostat reports its operating state using the Operating State Command Class. Open window detection can be enabled or disabled. The device supports the Indicator Command Class, which can flash the backlight of the display. The battery Command Class reports the current battery level in specific instances. Protection Command Class allows disabling local control of the thermostat. The device supports multiple Command Classes, including those for security and association.
