HEATIT 5430581 WiFi6 Thermostat Black Matt

INTRODUCTION

Heatit Pro is an electronic thermostat designed for electrical heating, waterbased heating and cooling systems. The thermostat has a user-friendly interface that can be controlled from the buttons on the front of the thermostat. Heatit Pro has 2 modes; Heat and Cool. 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 one built-in room temperature sensor. Two additional external temperature sensors may also be connected. Heatit Pro has the option of a weekly program and open window detection. The product 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. Heatit Pro has active power metering, which allows the user to see the real time power consumption. The thermostat can withstand a load of max 16A/3600W at 230VAC. We recommend a contactor for loads above 13A.

INSTALLATION

Position the thermostat and mount it into the junction box using 2 screws. Position the thermostat front over the part mounted in the junction box, then carefully press the front until it clicks into place. In order to get power metering values, the load needs to be connected to both heating L + N. Never change the front from one thermostat to another.

FACTORY RESET

Enter the menu by holding the center button for about 5 seconds, navigate in the menu with the “+” button til you see “ADVA”. Press the Center button once, then, navigate 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 byholding the Left and Right 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 for the date and time.

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 setpoint temperature.

Hysteresis
Hysteresis will turn on and off the load based on the hysteresis value in comparison to the setpoint. You can make changes to the thermostat hysteresis. It may be changed by entering the local settings menu and pressing the Center button when “HYST” is displayed. Here you can choose values between 0.5 and 10. The default setting is 0.5°C. When using waterbased heating we recommend a hysteresis of 1.0°C.

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 setpoint.

WATERBASED HEATING/ELECTRICAL HEATING

The thermostat can be set to be used with either electrical heating, or waterbased heating. Depending on which choice is made, some menu items and operations will be different.

Automatic valve exercise
Valve exercising is beneﬁcial during longer periods of inactivity to ensure the proper operability of the valves and prevent the valves from getting stuck. If not exercised, corrosion or other buildup may result in the valve becoming inoperable or prevent complete closure. NB! This function on by default with 5 minutes timer when waterbased heating is active. If you do not control an actuator, it is recommended to turn off this function.

Waterbased heating/NCNO
While in waterbased heating mode, you can change the NCNO menu option. Using this menu option will change between Normally Open and Normally Closed. Holding center button when NCNO is displayed will allow you to adjust automatic valve exercise timer.

To enter the settings menu, hold the Center button for 5 seconds. The display will show “PROF”. You are now in the settings menu. You can now scroll up and down using the Left and Right buttons. Some menu items are in the “ADVA”
(advanced) submenu. To navigate the submenus, press the Center button once to enter or exit the submenu. 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.

DISPLAY MENU STRUCTURE
See ﬂowchart at the end of this manual.

WEEKLY SCHEDULE
To enable the weekly schedule, enter the menu, navigate to “PROF” and select “AUTO”. The following options are available, each with six different time slots to conﬁgure the temperatures.

WEE Mon-Fri and Sat-Sun program.
WDA Mon-Sat and Sun program.
WEN Same program whole week.
DAY Each day individually programmed with 6 settings.

STANDBY AND MAIN SCREEN

When the thermostat remains untouched for a while, it will automatically go to the standby screen. By pressing any button once, you will see the thermostats setpoint. By pressing the Left or Right button multiple times, you will change the setpoint.

WEEKLY SCHEDULE AND ADAPATIVE FUNCTION

Weekly schedule
You can customize the thermostat to change its setpoint at different times throughout the week. There are several weekly files and preset times available that you can configure.

Setting a weekly schedule
Enter the menu and press the center button on “PROF”, then select “AUTO”, and hold the center button to confirm the selection. After selecting “AUTO”, there will be a “PROG” option in the menu. Press the center button to enter the programming mode for the weekly schedule. There you can choose your program type, and configure the times and temperatures.

Adaptive function
The adaptive function learns the time required to heat the room. The thermostat will aim to reach the scheduled temperature at the specified time in your weekly plan.

ACTIVE POWER METERING VALUES IN MENU
The device supports active power metering to give insight into the power consumption of the heating. The active power metering information can be seen from the menu. Navigate to “POW” under “ADVA” and press the Center button to scroll through amps, voltage, watts and kWh.

SIZE OF LOAD
Hold the center button for 2 seconds while “POW” is displayed to manually set the value of the connected load from 100W to 6500W with 100W increments.

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 the local settings menu (“MODE”).

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

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) thefloor limiter FHI is automatically set to 27°C. When using anyother 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 the local settings menu. 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 ±10°C. The temperature calibration can be performed from the menu using CAR, CAE and CAF. The adjusted value will be displayed indicating what the thermostat uses for regulation.

SENSOR TYPE IN MENU STRUCTURE

Internal sensor CAR
External sensor CAE
Floor sensor CAF

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 (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 Right 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

CHILD LOCK

The child lock function disables the buttons on the display. It will show “LOCK” when attempting to operate it while the function is enabled. To enable or disable the function, hold the Center and Left buttons for 10 seconds. Enabling the function will show “LOCK” in the display, disabling the function will show “OPEN”.

OPEN WINDOW DETECTION
Open Window Detection (OWD) is a function which will reduce the thermostat setpoint on detection of an open window. This happens when the temperature sensor registers a rapid temperature drop. When OWD is active, the setpoint 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 thetemperature increases by 3°C. OWD can also be cancelled manually by increasing/decreasing the setpoint 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”.

ANTI-FREEZE FUNCTION

Anti-freeze (ANTI) helps to reduce the chance of damage due to very low temperatures. When anti-freeze is active, you can choose a setpoint between 5°C and 10°C. The thermostat will start heating even when it is in OFF mode.

ERROR CODES
