INTRODUCTION

Heatit WiFi6 is an electronic thermostat designed for electrical heating. The thermostat can be controlled using the ”MyHeatit” App via Wi-Fi, Bluetooth (BLE), or by the buttons on the front of the thermostat. The thermostat has a user friendly interface.

Heatit WiFi6 has 3 modes; Heat – Cool and Eco.

The thermostat fits in standard European junction boxes and may be used with most System 55 frames. It has a sturdy metal frame for secure fastening on the junction box. The thermostat has a built-in room temperature sensor. Two additional external temperature sensors may also be connected. The device has an open API and supports Amazon Alexa and Google Home (open API, Amazon Alexa and Google Home is pending).

The thermostat can communicate over a local API, where the user can make integration with a local gateway, server, controller that offers such a service.

The installer can configure and set up the system via Bluetooth. After the system is set up, the installer can transfer the property to the customer. The customer can then transfer the system to their Wi-Fi network.

Heatit WiFi6 has active power metering and it gives you real time information about your power consumption. It also allows you to set the power metering value manually in case of connection with a contactor.

The device has implemented ZeroX technology. This technology makes sure the relay switches at 0V when turning on and off. With this technology the thermostat will have a much longer lifetime.

The device can withstand a load of max. 16A/3600W at 230VAC. We recommend a contactor for loads above 13A.

QUICK START

Upon connecting the device to power, it will automatically enter add mode for a duration of 60 minutes.

Switch off the mains voltage (disable the fuse).
Open the junction box.
Connect the wires according to the description in chapter “Connections”. Optional: Connect external wired sensors.
After verifying the connections, switch on the mains voltage.
In the ”MyHeatit” App, choose “Add Device”, enter your Wi-Fi details, search for and select your device.
The thermostat will display “INCL” when the thermostat is successfully added.

NB! If adding/removing fails, Err (error) will appear in the display

You may also initiate a reset by holding the right and centre 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.

STARTUP

After powering up the device for the first time, all parameters will have default settings and the thermostat will start by asking which sensor mode should be used.

PRINCIPLES OF REGULATION

The thermostat uses temperature readings retrieved from the internal sensor and/or from external wired sensors to regulate the temperature. The thermostat will regulate the temperature using hysteresis or PWM, based on the set point temperature. To select either “HYST” or “PWM” you can find the “REG” menu option or use Parameter 13 “Regulation mode” (“OPER”).

Hysteresis

Hysteresis will turn on and off the load based on the hysteresis value in comparison to the set point. You can make changes to the thermostat hysteresis. You may choose hysteresis values between 0.3°C and 3.0°C using Parameter 14 “Temperature control hysteresis” (“HYST”). The default setting is 0.5°C. When using water based heating we recommend a hysteresis of 1.0°C.

You may also change the hysteresis by entering the local settings menu and holding the Center button for 2 seconds when “REG” is displayed. Here you can choose values between 0.3 and 3.0.

Pulse-width modulation PWM
With PWM regulation enabled, the thermostat will regulate based on duty cycles. The thermostat is turned 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.

To enter the settings menu, hold the Enter button for 5 seconds. The display will display “OFF”. You are now in the settings menu. While in the settings menu, “SET” will be displayed in the bottom right of the display. You can now scroll up and down using the Left and Right buttons. Some options have sub menus. To navigate the sub menus, press the Center button once to enter or exit the sub menu. Press the Left and Right buttons to find your desired value and hold the Center button for 2 seconds to confirm your selection. “STOR” will appear to indicate settings are stored.

See flowchart at the end of this manual.

TEMPERATURE SHOWN IN DISPLAY

By default, the temperature shown on the display while in standby state is the set point. This may be altered with Parameter 15:”Temperature display”. It may also be changed by entering the local settings menu and holding the Center button for 2 seconds when “MODE” is displayed. You can choose between “SETT” and “RELT”. “SETT” is the Set point temperature and “RELT” is the real-time temperature.

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.
By pressing any button once, you will see the measured temperature. By pressing the Left or Right button multiple times, you will change the set point.

The device supports power metering to give insight into the power consumption of the heating. The total consumption of the device can be seen in the system from the “kWh” menu option. The total consumption data can be reset by holding the Center button while in the kWh menu.

SIZE OF LOAD

In the “load” menu or from Parameter 26 “Size of load”, the load value can be set manually if the load is not directly connected to the thermostat. The size of load can be adjusted in 100W increments up to 9900W.

CHOICE OF SENSOR

The thermostat has multiple sensors and sensor modes. This lets you configure the thermostat to work correctly in most installations. The sensors and modes may be selected from either the local settings menu or via Parameter 2; ”Sensor mode” (“OPER”).

Available sensor modes:
F: Floor sensor
A: Internal room sensor
AF: Internal room sensor + Floor sensor
A2: External room sensor
A2F: External room sensor + Floor sensor
PWER: Power regulator mode (no sensor used)

NOTE: Some types of floor require that a floor sensor is connected in order to limit the floor temperature to a maximum of 27°C (check the manual from the floor manufacturer). When the thermostat is used in (AF or A2F) the floor limiter FHI is automatically set to 27°C. When using any other sensor type (A, F or A2) the minimum and maximum limits are 5°C and 40°C respectively.

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: ”Sensor value“ (“SEN”). The supported sensor values are as follows: 6.8, 10, 12, 15, 22, 33, 47 or 100KΩ.
The factory default value is 10kΩ. When connecting both the floor sensor and the external sensor, make sure to use sensors with the same Ohm value.

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, 11 and 12. The calibration can also be performed from the menu using CAR, CAE and CAF. The adjusted value will be displayed in the app indicating what the thermostat uses for regulation.

SENSOR TYPE	IN MENU STRUCTURE	PARAMETER
Internal sensor	CAR	10
External sensor	CAE	11
Floor sensor	CAF	12

BRIGHTNESS

Using the menu choices “BR1” and “BR2”, the brightness of the display in Active and Standby state can be changed respectively. “BR1” and “BR2” are also included in the device as Parameter 16 “Active display brightness” (“BR1”) and Parameter 17 “Standby display brightness”(“BR2”)

DISPLAY ON/OFF (DON/DOFF)

The thermostat has a display ON/OFF function which decides whether the display should turn completely off when in Standby. To enable/disable this function, hold the Left and Center buttons for 10 seconds. The display will show “DOFF” when the function is activated and “DON” when the function is disabled. When operating any button, the display will light up.

DISPLAY ICONS

ICON	DESCRIPTION
This icon will be displayed while the relay is on and the thermostat is in

either Heating or Eco mode.
| This icon will be displayed while the relay is on and the thermostat is in Cooling mode.
| This icon shows the current signal strength.

CHILD LOCK

Child lock is a function for disabling the buttons from the display locally. It will show “LOCK” when attempting to operate it while the function is enabled. To enable or disable the function, hold the Left and Right buttons for 10 seconds.
Enabling the function will show “LOCK” in the display, disabling the function will show “OPEN”.

OPEN WINDOW DETECTION OWD

Open Window Detection (OWD) is a function which will reduce the thermostat set point on detection of an open window. This happens when the temperature sensor registers a rapid temperature drop.

When OWD is active, the set point is reduced to 5°C in order not to waste energy. OWD will automatically be cancelled if OWD has been active for more than 1 hour, or if the temperature increases by 3°C. OWD can also be cancelled manually by increasing/decreasing the set point with the Left and Right buttons.

By default, OWD is not enabled. The feature may be enabled by selecting “OWD” from the menu. Choose between options “OFF” and “ON”. It can also be enabled by setting Parameter 25 “Open window detection” to 1.

SAFETY FEATURES

The device has safety features to ensure safe operation and warn the user of any faults/unexpected behaviour. The device has an Overheat and Overload function. If the thermostat registers an Overheat or Overload incident, the thermostat will switch off and an error will appear in the display

Overheating
The device features internal temperature sensors that detect overheating. It warns the user and turns off the relay to prevent any damage.

When overheating is detected, the device will:

Turn off the relay.
Display Err6 in the display.
Send a notification to the “MyHeatit” App.

Overload
The device features a 16A overload protection. The overload is triggered if there is a current draw of more than 16A.

When overload is detected, the device will:

Turn off the relay.
Display Err7 in the display.
Send a notification to the “MyHeatit” App.

Sensor failure
The device has the ability to detect when there is no sensor connected or the sensor is broken or otherwise defective, causing an open circuit.

When the device detects the sensor error, the device will:

Turn off the relay.
Display an error in the display, changes based on which sensor is not connected/faulty

To clear the “Sensor not connected” error the device has to be disconnected from the mains, and the wiring and sensor(s) need to be checked. When the fault is resolved the mains can be reconnected and the device will function normally again.

ASSOCIATIONS (PENDING)

Devices interact with other devices. The relationship between these devices is called an association. In order to control a subordinate device, the controlling device needs to maintain a list of devices that will receive controlling commands. These lists are called “Associations”. They are always related to the specific event triggered (e.g., relay state change). In case the event is triggered, all the devices stored in the respective association will receive a command to perform an action.

Setting and Removing Associations
On the “Devices” page, select the device intended for controlling another device. Click “Associations”, choose the desired function (e.g., relay state, setpoint). Then select the devices to be controlled by the controlling device and hit “Save”.
