Description:Heatit Z-TRM3 is an electronic thermostat for electrical floor heating, designed to be mounted in a standard flush box. The thermostat has a built-in Z-Wave chip that can be connected with Home Automation systems. Heatit Z-TRM3 has SmartStart. This feature allows the user to include all devices with SmartStart by scanning the QR codes on the devices. On startup all the devices will automatically be included in the gateway (requires SmartStart compability). This saves the installer a lot of work. Heatit Z-TRM3 is equipped with a single pole switch and fits into System 55 frames. The thermostat can withstand a load of max 16A /3600W 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 5 associations (relays, wall plugs etc.). The thermostat is designed for electrical heating. It may be used for waterbased heating if the thermostat is linked with the Heatit Z-Water.

Where to find S2 DSK on product

The Z-Wave DSK can be found in the QR-Code and is located in 3 locations;

1. On the product box.

2. On the physical product, placed on the black plastic underneath the front.

3. On the PCB internally.

Classic Exclusion

Remove.

The primary controller/gateway has a mode for removing devices. Please refer to your primary controller manual on how to set the primary controller in remove mode. The device may only be removed from the network if the primary controller is in remove mode. When the device is removed from the network, it will NOT revert to factory settings.

Removing mode is indicated on the display by rotating LED segments on the display. This lasts until the timeout occurs after 90 seconds, or until the module has been added/removed in the network. Confirmation will show Inc/EcL on the display. Exit programming mode by choosing ESC in the menu. Your thermostat is

now ready for use with default settings.

NB! When the thermostat is removed from the gateway, the parameters are not reset.

Factory Reset Procedure

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

NB! Please use this procedure only when the primary controller/gateway is missing or otherwise inoperable.

The device will display rES for 10 seconds while performing a factory reset. When rES no longer is displayed, the thermostat has been reset.

Classic Inclusion

Add.

The primary controller/gateway has a mode for adding devices. Please refer to your primary controller manual on how to set the primary controller in add mode. The device may only be added from the network if the primary controller is in add mode.

There are two ways to add the Heatit Z-TRM3 to a Z-Wave network.

METHOD 1: STANDARD (MANUAL)

1. Press Center (confirm) for 10 seconds. The display will show OFF.

2. Press Right (down) 5 times until you see Con on the display.

3. Start the add/remove device process in your primary controller.

4. Start the add/remove mode in the Heatit Z-TRM3 by pressing Center (confirm) for approximately 2 seconds.

Adding mode is indicated on the display by rotating LED segments on the display. This lasts until the timeout occurs after 90 seconds, or until the module has been added in the network. Confirmation will show Inc/EcL on the display. Exit programming mode by choosing ESC in the menu. Your thermostat is now ready for use with default settings.

METHOD 2: SMARTSTART (AUTOMATIC)

SmartStart enabled products can be added into a Z-Wave network by scanning the Z-Wave QR-Code present on the product with a controller providing SmartStart inclusion. No further action is required and the SmartStart product will be added automatically within 10 minutes of being switched on in the network vicinity.
