What is Z-Wave?

Z-Wave is the international wireless protocol for communication in the Smart Home. This device is suited for use in the region mentioned in the Quickstart section.

Z-Wave ensures a reliable communication by reconfirming every message (two-way communication) and every mains powered node can act as a repeater for other nodes (meshed network) in case the receiver is not in direct wireless range of the transmitter.

This device and every other certified Z-Wave device can be used together with any other certified Z-Wave device regardless of brand and origin as long as both are suited for the same frequency range.

If a device supports secure communication it will communicate with other devices secure as long as this device provides the same or a higher level of security. Otherwise it will automatically turn into a lower level of security to maintain backward compatibility.

For more information about Z-Wave technology, devices, white papers etc. please refer to www.z-wave.info.

Product Description

Heatit Z-TRM2fx is equipped with a single pole switch and it fits most System 55 frames (Elko RS16, Schneider Exxact, Gira, Jung etc.). The thermostat can withstand a load of max 13A /2900W at 230V. At higher loads the thermostat must control a contactor. The thermostat may be connected to two wired external sensors. The thermostat has the capacity of up to 8 associations (relays, wall plugs etc.).The thermostat is designed for electrical heating.

Prepare for Installation / Reset

Please read the user manual before installing the product.

In order to include (add) a Z-Wave device to a network it must be in factory default state. Please make sure to reset the device into factory default. You can do this by performing an Exclusion operation as described below in the manual. Every Z-Wave controller is able to perform this operation however it is recommended to use the primary controller of the previous network to make sure the very device is excluded properly from this network.

Reset to factory default

This device also allows to be reset without any involvement of a Z-Wave controller. This procedure should only be used when the primary controller is inoperable.

By pressing buttons Right and Center (down and confirm) for 20 seconds, the thermostat will perform a complete factory reset.

Safety Warning for Mains Powered Devices

ATTENTION: only authorized technicians under consideration of the country-specific installation guidelines/norms may do works with mains power. Prior to the assembly of the product, the voltage network has to be switched off and ensured against re-switching.

Quick trouble shooting

Here are a few hints for network installation if things dont work as expected.

  1. Make sure a device is in factory reset state before including. In doubt exclude before include.
  2. If inclusion still fails, check if both devices use the same frequency.
  3. Remove all dead devices from associations. Otherwise you will see severe delays.
  4. Never use sleeping battery devices without a central controller.
  5. Dont poll FLIRS devices.
  6. Make sure to have enough mains powered device to benefit from the meshing

Association - one device controls an other device

Z-Wave devices control other Z-Wave devices. The relationship between one device controlling another device is called association. In order to control a different device, the controlling device needs to maintain a list of devices that will receive controlling commands. These lists are called association groups and they are always related to certain events (e.g. button pressed, sensor triggers, ...). In case the event happens all devices stored in the respective association group will receive the same wireless command wireless command, typically a 'Basic Set' Command.

Association Groups:

Group Number Maximum Nodes Description
1 1
Lifeline. (Normally used by the Z-Wave Controller) Sends:
- Thermostat Setpoint Reports
- Thermostat Mode Reports
2 5 Send Multilevel Sensor Reports.
3 5 Send Multilevel Sensor Reports.
4 5 Send Binary Switch Set commands representing the status of the internal relay.

Configuration Parameters

Z-Wave products are supposed to work out of the box after inclusion, however certain configuration can adapt the function better to user needs or unlock further enhanced features.

IMPORTANT: Controllers may only allow configuring signed values. In order to set values in the range 128 ... 255 the value sent in the application shall be the desired value minus 256. For example: To set a parameter to 200 it may be needed to set a value of 200 minus 256 = minus 56. In case of a two byte value the same logic applies: Values greater than 32768 may needed to be given as negative values too.
