The MCS 350 Tuya is designed to control domestic electrical heating systems (heating mats, film heaters or heating cable sections). The thermostat maintains a comfort temperature of the heated surface and ensures rational power consumption. The thermostat provides the control using two temperature sensors: floor sensor and air sensor (included in the sc ope of delivery), both simultaneously and individually. The thermostat enables to control the water warm floors under certain conditions, and when using a thermal he ad of the normally closed (NC) type with 230 VAC control voltage. The thermostat is mounted onto a wall in close proximity to installation wires of the heating system used.
SPECIAL FEATURES
The thermostat enables to control your warm floor both directly from the device touch screen and by using the Tuya Smart application installed on a smartphone. The thermostat shall be connected to a smartphone via Wi-Fi.
WiFi CONNECTION GUIDELINES
IMPORTANT!
SAFETY WARNINGS
Only qualified electricians are allowed to work on electrical connections and the electric supply of the device according to national laws and regulations. Otherwise the warranty invalidates. Switch off power from all wiring before installing, testing or replacing the thermostat. Only use electrical plastic wall mounting boxes for the thermostat installation. Ensure that the sensor can be placed into and removed from the corrugated tube (Ø16mm); once during installation of the tubing and again before installation of the floor finish!
Sensor installation
The floor temperature sensor cable has to be placed into a seperate corrugated tube according to EN 61386-1. The sensor should be placed centrally between the heating conductor. Route the heating mat cold lead through the second corrugated tube. Do not cross the cold lead over or place it closer than about 2 cm to the mat heating wires! A standard plastic round recessed electrical box with 230 VAC power supply is preferred for installation at the chosen thermostat location. A ground fault circuit breaker (30 mA) should be used for the 230 VAC heating mat circuit. Ensure that the sensor can be placed into and removed from the corrugated tube (Ø16mm); once during installation of the tubing and again before installation of the floor finish!
CONNECT THE THERMOSTAT
IMPORTANT! We recommend to use the services of qualified specialists when installing the thermostat and heating system. The electrical connection and connection to the power supply must be performed by a professional electrician in compliance with the applicable national laws, rules and regulations. The installation instructions and wiring diagram do not replace the professional skill of the device installer. Disconnect your local wiring from the mains before connecting the thermostat or disconnecting it to check or replace it. Electrical connections of the device and its connection to the mains must be performed by a qualified electrician.
We recommend the following procedure of the device installation:
IMPORTANT! Avoid damage and bending of the connector’s contacts in the course of the mounting..
To display information and control operating modes, the thermostat uses a liquid crystal touch panel display with functional control buttons depicted on it. The control buttons are as follows:
MAIN INDICATION SCREEN
There are two display modes of the main indication screen:
The large figures show the set floor temperature.
CONNECTION TO A SMARTPHONE
In order to be able to conveniently operate the thermostat via the “Tuya Smart” app, the device first needs to be added to the app and connected with your smartphone using WiFi. This requires the following steps:
Please note:
SWITCHING THE THERMOSTAT ON
The device is switched on by pressing and holding the button.
LOCKING/UNLOCKING
To ensure the childproofing and protect from accidental button presses, the device is equipped with a lock. It turns on automatically, 40 seconds after the last touch of any button on the device. You can force the lock by holding the power button for more than 1 second but less than 3 seconds. To remove the lock, press the
OPEN AND LEAVE THE MENU
To open the menu for the thermostat settings press the button and hold for 3 seconds. You can leave the menu with the button.
SWITCHING THE THERMOSTAT OFF
To turn OFF the device, you must hold the button
Please note:
With the exception of date and time, all other settings described below can be performed via the Tuya Smart App. However, if required, you can also perform the settings directly at the thermostat
Attention:
After an interruption of the voltage supply (e.g. due to a power failure), the time and date settings are retained for 4 hours. All other settings like temperatures, operation mode etc. will be retained for 12 months
The thermostat provides three basic operating modes:
The thermostat enables to control heating systems by using two temperature sensors
There are three basic control modes:
SETTING THE OPERATING MODE
To set the operating mode required, press the button
PERMANENT TEMPERATURE MAINTENANCE MODE
This mode (Figure 7a) is used when there is a need to constantly maintain the set temperature. Set the temperature by pressing “+” and “-” buttons. The temperature display starts flashing. Temperature setting is possible in the range of +12 … +45 °C. Set the desired temperature and press the button
ANTI-FREEZING MODE
The thermostat in the “Anti-freezing” mode (Figure 7b) can reduce the temperature in heated rooms for a long time to a level that prevents freezing, thereby saving electric energy. This mode can be used when there is no need for permanent comfortable heating of the room, for example, during the absence of the owners of the house. In this mode, the maintenance temperature is reduced to the “anti-freezing” temperature. The “Anti-freezing” mode is similar to the “Permanent temperature maintenance” mode, only the temperature can be set in the range of +5 … +12 °C.
PROGRAM MODE
This mode (Figure 7c) is an effective means of saving electric energy in the case when there is no need for permanent heating, and heating is switched ON only during certain periods of the day. The program mode is event-driven, i.e. the thermostat operates with four events per each day of the week, the time of which you can set with an accuracy of 10 minutes. Depending on the event and day of the week the thermostat automatically controls the heating according to the set COMFORT and ECONOMY temperature. The temperature can be set in the range from +5 … +45 °C.
The events “Waking up” and “Coming home” are related to the COMFORT temperature, the events “Leaving home” and “Going to sleep” are related to the ECONOMY temperature.
To program the thermostat, press and hold the
OPEN WINDOW DETECTION MODE
The thermostat provides the “Open window detection” mode. In the factory settings of the device, this mode is disabled. You can enable this feature only via the Tuya Smart App. The thermostat permanently monitors the air temperature in the room. This happens even if the control is based on the floor sensor only. If the room temperature has dropped by more than 3 degrees within 5 minutes, the thermostat forcibly turns OFF the heating for 30 minutes (Figure 8). After this time, heating control continues in the preset mode.
TIME AND DATE SETTING
Press the
SELF-LEARNING MODE
When operating in program mode, the thermostat has the ability to study the temperature characteristics of the room, turn ON the heating in advance and reach the temperature set by you exactly at the specified time. The self-learning mode can be disabled (see section “Control mode setting”). In this case, the thermostat will turn ON the comfort heating exactly at the time you set.
Use the “+” button to set the desired control mode. At the same time, the active icon will flash. Inactive will not light up. The “-” button enables/disables self-learning mode
After selecting the required control mode, fix it by pressing the button
AIR TEMPERATURE READINGS CORRECTION
The temperature measured by the room sensor may deviate from the actual room temperature due to the fact that the sensor is installed inside the device housing. Therefore, the slight self-heating of the thermostat during its normal operation can affect the temperature measurement, just like its location such as near to other heat sources, windows, doors, etc. In order to compensate such a possible deviation, the room sensor can be calibrated as follows. Press the button and hold it for 3 seconds. Then press the button
SELECTING FLOOR SENSORS FROM OTHER MANUFACTURERS
Press and hold the button for 3 seconds. You will be taken to the control mode setting window. Press the button
SELF-DIAGNOSTICS
FLOOR TEMPERATURE SENSOR OPERABILITY CHECK
The thermostat continuously monitors the operation of the temperature sensor. In the event of its failure (breakage or short circuit of the installation wires), the display will show information about the malfunction (Figure 16, 17). In this case you need to contact your dealer/installer to repair or replace the temperature sensor
The thermostat provides the ability to return to factory settings. To do this, in operating mode, press and hold the “+” and “-” butt ons until the device is turned OFF. After that, just turn ON the thermostat. By default, the following event times and corresponding maintenance temperatures by weekdays are preset:
