Heatit Z-TRM6 DC Z-Wave thermostat 3A (Dry Contact)

Technical characteristics

Home Automation Technology	Z-Wave Serie 800

More info

Heatit Z-TRM6 DC is an electronic thermostat with potential-free relay, designed for the control of boilers, heat pumps and actuators. The thermostat can be controlled via your Z-Wave network or via the buttons on the front. The thermostat has a user-friendly interface. The thermostat for boilers or systems that require a dry contact relay, can be controlled via your Z-Wave network or physically by the buttons on the front of the thermostat itself. The thermostat has a user-friendly interface. As it has a cool-heat mode, it is ideal for operating solenoid valves or actuators on underfloor heating/cooling water manifolds that do not run on 220V.

Heatit Z-TRM6 DC has 3 modes; Heat - Cool and Eco.

The thermostat fits standard European junction boxes and can be used with most System 55 frames. It has a robust metal frame for secure fixing in the junction box. The thermostat has an integrated room temperature sensor. Two additional external temperature sensors can also be connected.

The Heatit Z-TRM6 DC allows manual adjustment of the power measurement value.

The thermostat can be configured with multiple associations and can be used as a master thermostat. It can control up to 10 thermostats and 10 external relays, e.g. wall sockets.

How the Heatit Z-TRM6 Z-Wave Thermostat Regulates Temperature

The thermostat uses temperature readings obtained from the internal sensor and/or external wired sensors to regulate the temperature.
the temperature. The thermostat will regulate the temperature using hysteresis or PWM, based on the setpoint temperature.
To select "HYST" or "PWM", you can find the menu option "REG" or use parameter 13 "OPER".

When selecting regulation via Hysteresis
The hysteresis will switch the load on and off depending on the hysteresis value compared to the setpoint. You can make changes to the hysteresis of the thermostat. You can choose hysteresis values between 0.3°C and 3.0°C using parameter 14. The default setting for the default setting is 0.5°C. When water heating is used, we recommend a hysteresis of 1.0°C.
You can also change the hysteresis by entering the local settings menu and holding down the centre button for 2 seconds when "REG" is displayed. Here you can choose values between 0.3 and 3.0.

When PWM regulation is selected
With PWM regulation activated, the thermostat will regulate according to the duty cycles. The thermostat switches on and off in percentage intervals of the cycle. The amount of time the relay will be on is based on how far the measured temperature is from the set point.

KEY POINTS:

Dry contact - Special thermostat to control potential free connected loads.

Modes - The thermostat has 3 modes: Heat - Cool and Eco. Cool and Eco are new features.

Metal frame - The thermostat has a metal frame for secure mounting in the junction box, which increases the durability of the product in contrast to previous plastic solutions.

Associations - The thermostat can be configured with multiple associations and can be used as a master thermostat. It can control up to 10 thermostats and 10 external relays.

Power regulator - Heatit ZTRM-6 DC has a built-in power regulator as an alternative to temperature regulation.

Hysteresis - With hysteresis regulation activated, the thermostat will only regulate according to the temperature. The thermostat switches on and off depending on the hysteresis value in relation to the setpoint.

Pulse Width Modulation/PWM - With pulse width modulation control activated, the thermostat will regulate according to the cycles. The thermostat switches on and off in percentage intervals of the cycle.

Window open detection - With window open detection, the thermostat detects if a window is open, allowing it to cut off the heating when there is a rapid drop in temperature.

Manual power measurement - The thermostat has a manual power measurement that gives you an overview of the consumption in real time. The load size is set as a fixed value in the menu.

Push buttons - With a combination of push buttons and touch functionality, the thermostat is easier to use.

Where to find S2 DSK on product

The QR-Code is needed when including a device using S2 security or SmartStart. The DSK can be found in the QR-Code and is located;

• On the product.

• In the Quick Guide.

• On the packaging box/gift box.

Factory Reset Procedure

Enter the menu by holding the Center button for about 5 seconds, navigate in the menu with the ”+” button til you see FACT. Press the Center button until you see “-- --” blinking in the display, then hold for about 5 seconds to perform a reset.

You may also initiate a reset by holding the Right and Center buttons for 60 seconds.

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.

Please use this procedure only when the network primary controller is missing or otherwise inoperable.

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 to the network if the primary controller is in add mode.

An always listening node must be powered continuously and reside in a fixed position in the installation to secure the routing table. Adding the device within a 2 meter range from the gateway can minimize faults during the Interview process.

Standard (Manual)

Add mode is indicated on the device by rotating LED segments on the display. It indicates this for 90 seconds until a timeout occurs, or until the device has been added to the network. Configuration mode can also be cancelled by performing the same procedure used for starting

Configuration mode.

1. Hold the Center button for 5 seconds.

The display will show “OFF”.

2. Press the ”+” button once to see “CON” in the display.

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

4. Start the configuration mode on the thermostat by holding the Center button for approximately 2 seconds.

The device is now ready for use with default settings.

If inclusion fails, please perform a ”remove device” process and try again. If inclusion fails again, please see “Factory reset”.

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.

Standard (Manual)

Remove mode is indicated on the device by rotating LED segments on the display. It indicates this for 90 seconds until a timeout occurs, or until the device has been removed from the network. Configuration mode can also be cancelled by performing the same procedure used for starting

Configuration mode.

1. Hold the Center button for 5 seconds.

The display will show “OFF”.

2. Press the ”+” button once to see “CON” in the display.

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

4. Start the configuration mode on the thermostat by holding the Center button for approximately 2 seconds.

NB! When the device is removed from the gateway, the parameters are not reset. To reset the parameters, see Chapter ”Factory reset”.
