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. We recommend using multiple 230VAC  

devices to create a mesh network.  

To access the batteries and power connector, or to mount the  

device, hold the sides of the display and gently pull outwards to  

detach the thermostat from the mounting plate.  

1. Hold the Center button for 5 seconds.

DESCRIPTION  

INTRODUCTION  

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.

When either of these procedures has been performed, the  

thermostat will perform a complete factory reset. The device  

will display “RES” for 5 seconds while performing a factory  

reset. When “RES” is no longer displayed, the thermostat has  

been reset.  

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

ADD/REMOVE  

55mm  

The primary controller/gateway has a mode for adding or  

removing devices. Please refer to your primary controller  

manual on how to set the primary controller in add/remove  

mode. The device may only be added or removed from the  

network if the primary controller is in add/remove mode. When  

the device is removed from the network, it will NOT revert to  

factory settings.  

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.  

If the thermostat is to control a relay, an association from  

Group 2 must be created from the thermostat to the relay that  

is to be controlled.  

Please use this procedure only when the primary controller is  

missing or otherwise inoperable.  

84mm  

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.  

Disclaimer: When using the Heatit Z-Temp3 to control multiple  

relays on a Heatit Z-Water (Art. no. 4512475) or a Heatit  

Z-Water2 (Art. no. 4512495), only use relays 1 through 7. Do not  

use relays 8, 9, or 10 for this purpose.

DESCRIPTION  

Adding the device within a 2 meter range from the gateway can  

minimize faults during the Interview process.  

This icon will be displayed while the relay is on and  

the thermostat is in either Heating or Eco mode.  

All communication between Heatit Z-Temp3 and the controlled  

device is 100% wireless.  

If the thermostat is to control other thermostats as a master  

thermostat, an association from Group 3 and Group 4 must be  

created from the master thermostat to the thermostats to be  

controlled.

There are two ways to add the device to a Z-Wave network.  

We develop and design our products according in accordance with our strict quality  

requirements (ISO 9001) and environmental requirements (ISO 14001). All electrical  

installations must be carried out by an authorized electrical installer. The product  

must be installed in accordance with our installers manual and national building  

codes. Any wrongful installation, misuse, damage of the product, is not covered  

under warranty. Updated documentation is available at www.heatit.com and/or  

documents.heatit.com. Heatit Controls AB can not be held liable for any type of  

errors or omittances in our product information. Product specifications may change  

without further notice.  

This icon will be displayed while the relay is on and  

the thermostat is in Cooling mode.  

Standard (Manual)  

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.  

Add/remove mode is indicated on the device by rotating  

LCD segments on the display. It indicates this for 90 seconds  

until a timeout occurs, or until the device has been added to/  

removed from the network. Configuration mode can also be  

cancelled by performing the same procedure used for starting  

Configuration mode.  

CONNECTIONS  

This icon shows the current signal strength.  

This icon shows the battery status.  

The Heatit Z-Temp3 can be connected to a 2.7 to 3.3VDC  

power supply via the optional cable, providing an alternative  

to using batteries. The cable is supplied with the Heatit  

Transformer 230VAC (Art. no. 45 126 48).  

Heatit Z-Temp3 can be associated with Heatit ZM Single Relay,  

other Z-Wave relays, Heatit ZM Thermostat, Heatit Z-TRM6  

Thermostat and other Z-Wave devices to control other types of  

heating solutions.

Summary of Contents

• Page 1: Heatit Z-Temp3 is a battery-operated thermostat designed for controlling water-based heating systems. It is easy to install without the need for wiring and can create a mesh network using multiple 230VAC devices. To access the batteries and power connector, detach the thermostat from the mounting plate. The device is ready for use with default settings after installation. Heatit Z-Temp3 has three modes: Heat, Cool, and Eco. The product is maintenance-free and intended for indoor use only. The thermostat can be mounted on a wall, junction box, or placed freely. Adding the device to a Z-Wave network can be done within a 2-meter range from the gateway. The device can be connected to a 2.7 to 3.3VDC power supply as an alternative to batteries. Heatit Controls AB declares that this device complies with relevant provisions of Directive 2014/53/EU.
• Page 2: Heatit Z-Temp3 er et godt valg ved restaurering eller ombygging av eksisterende bygninger, da den er enkel å installere uten behov for kabling. Vi anbefaler å bruke flere 230VAC-enheter for å lage et mesh-nettverket. Enheten er nå klar til bruk med standardinnstillinger. Heatit Z-Temp3 har 3 moduser: Heat, Cool og Eco. SmartStart-aktiverte produkter kan legges til et Z-Wave-nettverk ved å skanne Z-Wave QR-koden på produktet. All kommunikasjon mellom Heatit Z-Temp3 og den kontrollerte enheten er 100% trådløs. Produktet trenger ikke vedlikehold. Batteriets levetid kan variere avhengig av installasjonsmiljøet og bruksforholdene. Heatit Z-Temp3 kan assosieres med Heatit ZM Single Relay, andre Z-Wave reléer, og Heatit ZM Thermostat. For å få tilgang til batteriene og strømtilkoblingen, hold sidene på displayet og trekk forsiktig utover for å løsne termostaten fra monteringsplaten.
