heatit Z-TRM6 DC Z Wave Electronic Thermostat Instruction Manual Overview

Summary of Contents

• Page 1: Introduction to Heatit Z-TRM6 DC, an electronic thermostat designed for boiler control or actuators. The thermostat can be controlled through a Z-Wave network or via front buttons, featuring a user-friendly interface. Heatit Z-TRM6 DC has three modes: Heat, Cool, and Eco. It fits in standard European junction boxes and is compatible with most System 55 frames. The device includes a built-in room temperature sensor and allows for two additional external sensors. It supports multiple associations and can function as a master thermostat, controlling up to 10 thermostats and 10 external relays. The built-in relay has a maximum capacity of 3A for up to three 24VDC actuators. The device is compatible with all Z-Wave Plus certified devices from various manufacturers. It requires addition to an existing Z-Wave network for communication with other devices. Non-battery-operated nodes in the network act as repeaters to enhance reliability.
• Page 2: Quick start instructions include switching off mains voltage, opening the junction box, and connecting wires as per Chapter 6. Verify connections before switching on the mains voltage. Set the primary controller in add mode and hold the center button until OFF appears on the display. Press the + button to reach CON and hold the center button until a rotating light pattern is displayed. The thermostat will show INCL when successfully added; an error will appear if the process fails. Installation must be performed by a qualified electrician following national building codes. Power to the device must be disconnected at all times during installation. Max tightening torque for terminal screws is 2Nm, and using an end sleeve for multi-strand cables is advised. The product supports wiring of cables with a cross section of up to 1x2.5mm². To install the thermostat, detach the front piece, connect wires, align with mounting screws, and press the front until it clicks into place.
• Page 3: The thermostat will perform a complete factory reset and display “RES” for 5 seconds during this process. The primary controller must be in add/remove mode to add or remove devices from the network. Removing a device from the network does not revert it to factory settings. After powering up for the first time, the thermostat will ask which sensor mode to use. The thermostat regulates temperature using readings from internal or external sensors, employing hysteresis or PWM based on the setpoint temperature. Hysteresis values can be adjusted between 0.3°C and 3.0°C, with a default setting of 0.5°C. Pulse-width modulation (PWM) regulation allows the thermostat to control temperature based on duty cycles. To enter the local settings menu, hold the Center button for 5 seconds. SmartStart enabled products can be added to a Z-Wave network by scanning the Z-Wave QR-Code if supported by the primary controller. The factory reset can be initiated through the menu or by holding specific buttons for a set duration.
• Page 4: Temperature shown in display By default, the temperature shown on the display while in standby state is the setpoint. This may be altered with Parameter 15 “Temperature display”. Calibration If the temperature sensor readout is not correct, you can make minor changes to the temperature readout. The temperature readings can be calibrated by 6°C using Parameter 10 “CAR”, 11 “CAF” and 12 “CAE”. Standby and main screen When the thermostat remains untouched for a while, it will automatically go to the standby screen. The standby will by default show the setpoint temperature. Brightness Using the menu choices “BR1” and “BR2”, the brightness of the display in Active and Standby state can be changed respectively. Display on/off The thermostat has a display ON/OFF function which decides whether the display should turn completely off when in Standby. Size of load In the “load” menu or from Parameter 27 “Size of load”, the load value can be set manually. Choice of sensor The thermostat has multiple sensors and sensor modes. This lets you configure the thermostat to work correctly in most installations. Child lock Child lock is a function for disabling the buttons from the display locally. Open window detection Open Window Detection (OWD) is a function which will reduce the thermostat setpoint on detection of an open window. Selecting sensor value The thermostat allows the selection of multiple different resistance values of an NTC sensor and can be selected using either the local settings menu or via Parameter 3 “SEN”.
• Page 5: By default, OWD is not enabled. The feature may be enabled by selecting “OWD” from the menu. This device supports S2 and has a Z-Wave DSK QR-Code label that may be used when the device is added to the Z-Wave home network. The node information frame is the “business card” of a Z-Wave device. Z-Wave devices interact with other Z-Wave devices. The relationship between one device controlling another device is called an association. The device has safety features to ensure safe operation and warn the user of any faults/unexpected behavior. The device features internal temperature sensors that detect overheating. Associations may be assigned and removed via Z-Wave commands. Heatit Z-TRM6 DC has support for the Multi Channel Command Class. The device has the ability to detect when there is no sensor connected or the sensor is broken. S2 security enhances Z-Wave Plus with an additional layer of AES 128-bit encryption of the wireless Z-Wave communication.
• Page 6: Multi level switch device Thermostat setpoint set commands allow for use as master thermostat. Max nodes in group: 10. Thermostat mode set commands allow for use as master thermostat. Decides the lowest temperature allowed by the thermostat when using sensor mode A. Lifeline group to be used by primary controller sends various reports. Decides the highest temperature allowed by the thermostat when using sensor mode A. Calibrates the sensor by 6°C. Temperature report interval sets the time between consecutive temperature reports. Z-Wave products are designed to work out of the box after inclusion. Set setpoint for heating, cooling, and ECO modes.
• Page 7: This will unlock the thermostat until it goes back to standby, requiring you to unlock it again. Protection State to 0x02 means that no operation is possible and the thermostat can only be unlocked by setting Parameter 1 “Disable buttons” to 0, or by holding the Center and Right buttons for 30 seconds. Thermostat Setpoint is implemented with 3 setpoints, Heating, Cooling and ECO. Supported setpoints are from 5°C - 40°C with 0.5°C increments. It is possible to change the operating mode of the thermostat by sending a Thermostat Mode set command. The accessible operating modes are Heating Mode, Cooling Mode, and ECO Mode. The thermostat reports the operating state of the internal relay using the Command Class. The device supports the Indicator Command Class, which will flash the display. Protection Command Class allows you to disable local control of the thermostat, separate from the Child Lock function. Binary Switch commands are used to control external relays associated with group 2.
• Page 8: Supported command classes include S0, S2 Authenticated security, and S2 Unauthenticated security. The device supports various association groups and notifications. Thermostat dimensions are specified as 45.5mm, 50mm, 22mm, and 23.5mm. Thermostat controls include options to increase or decrease set temperature.
