Heating Load connected to Relay 25 – Max. 25 Amps
Thermostat Mounting
- Insert fixing screws through mounting holes of the power base and tighten.
- Re-attach the display to the power base. You can now restore power to the circuit and power up the STRATA_HEAT™ Smart LCD Thermostat. Follow the on screen instructions to set up the system. Once set up, a QR Code will appear.
Initial Setup
- Download the MySTRATA_HEAT App.
- Open the MySTRATA_HEAT App and scan the QR Code on the STRATA_HEAT Smart LCD Thermostat screen. Follow the instructions in the App to complete setup.
Step 5 – Add Location and Room
The MySTRATA_HEAT App will guide you through the setup of your STRATA_HEAT Smart LCD Thermostat. You will have to set up your house location and then the room within which your new STRATA_HEAT Smart LCD Thermostat is located.
Location
A location needs to be setup before a room can be configured and the STRATA_HEAT Smart LCD Thermostat device registered. Creating a location is user friendly and easy to follow, it is advised to have details of your current energy tariff and pricing to hand, as these will be required if you wish to use the energy monitoring features.
Room Setup
With a location now setup, the next step is to register a room in which your STRATA_HEAT Smart LCD Thermostat is located. This is the heating zone your thermostat will control. Ensure you set the correct System Type and Wattage of heaters connected.
NOTE: If an external relay or contactor relay has been installed please set System Type as Electric + Relay.
Welcome to the STRATA_HEAT™ Smart LCD Thermostat
Getting Started
How to quickly change the temperature
Use the slider or press the +/– icons to change your target temperature.
If in “Program” mode this will set a temporary override until your next heating period.
If in “Manual” mode this will set a fixed target temperature.
Once the target temperature is set above the current floor/air temperature the heating indicator will appear.
How to quickly change mode
Mode select allows you to quickly change from program, manual or vacation modes. You can also switch “Frost Protection” on or simply switch the “Heating Off” from here. Frost protection will ensure that the floor/air temperature does not drop below 44.0°F (6.5°C).
Heating
How to set a program
Setting a “Program” allows you to set comfort temperatures at set times throughout the day. Days can programmed individually, all days the same or weekdays as a block and weekends as a block. The choice is yours. 
To “Select additional days” press the days of the week and the squares will be highlighted in white as shown and will follow the programmed heating schedule. Once you are happy press “Accept” to save the heating schedule. This will return you to the previous screen to repeat as necessary.
NOTE: For tailor–made preset heating schedules for different room types press the three dots “…” on the weekly schedule page.
Setback Temperature
The “Setback” temperature is a lower energy efficient temperature when outside of a heating period.
How to set into Manual Mode
Setting into “Manual” mode allows you to set a fixed target temperature for the thermostat to achieve. The thermostat will continue to maintain this temperature until another operating mode or temperature is selected.
How to set into Vacation Mode
“Vacation Mode” allows you to override regular scheduling with a lower fixed temperature over a set time to save energy and avoid thermostat reprogramming.
How to switch “Heating Off”
The below will switch the heating off until you cancel it by pressing “Heating Off” on the homescreen or going into mode select and pressing the “Heating Off” slider.
Energy Monitor
How Energy Monitor works
The STRATA_HEAT™ Smart LCD Thermostat learns how you use your system and how your house reacts to heating and weather. Energy monitoring will show the amount of energy consumed over a certain time period. This will be calculated through system power (total system wattage) multiplied by efficiency and total run time. You will need to enter the power of your system, and in some cases, the efficiency. If you do not know these, speak to your installer or system manufacturer.
Changing the Power Settings
If you have entered the wrong system power during setup it can be changed in Energy Monitor; Power Settings.
Geo Location Settings
How Geo works
Geo is a unique technology developed by LATICRETE and built into the MySTRATA_HEAT App that uses an advanced algorithm to understand the most efficient heat settings for your home.
Working automatically; it learns your routines and location through background communication with your smartphone and lowers temperatures when you are away, only rising them up to your ideal comfort temperature in time for your arrival home.
Geo will operate when the thermostat is in the program or manual run modes. It is turned off by default. Use the MySTRATA_HEAT App to switch Geo on.

Troubleshooting
| Display is blank | Brightness | 1. Check that the standby brightness is not set to Off. |
| Power | 2. (Electrician Required) Electrician required to verify power is going to the STRATA_HEAT Smart LCD Thermostat and that it is correctly wired. | |
| ER1/ER2 | Sensor Error | (Electrician Required) Electrician required to verify that the floor sensor has been wired correctly. If it is correctly wired the electrician will need to check the resistance of the floor sensor using a multi meter. For temperatures between 68°F – 86°F (20°C – 30°C) the resistance of the floor sensor should measure between 8K ohms and 12K ohms.
If the electrician finds a fault, and the STRATA_HEAT Smart LCD Thermostat is in the room to be heated then it can be set into “Air Mode”.
To set into “Air Mode”, go to Sensors & Application in Advanced Settings and switch the probe off. |
| Heating is coming on earlier than programmed times | Adaptive learning (Early Start) On | Adaptive learning will use the historic heating/cooling rates for the time of day, historic external temperatures and the forecast external temperatures, to work out the heating start time in order to reach the comfort time at the start of the comfort period. It will only work in Program Mode. |
| Cannot to set above a certain temperature | Floor Type Temperature Limits | Delicate floor coverings need to have their temperatures limited. If the finished floor is set for wood, laminate, vinyl etc. you are unable to set the temperature above 81°F (27°C). |
| Wi-Fi Error Symbol | Wi-Fi not setup | If you have not done so, download the MySTRATA_HEAT App, go to Settings and Network setup and follow the on screen instructions to connect to a Wi-Fi Network. |
| Wi-Fi disconnected | Follow the step above to try and to re–connect to the Wi-Fi Network.
If the STRATA_HEAT Smart LCD Thermostat still fails to connect, see Wi-Fi Troubleshooting. | |
| Clock Sync Icon | Time and Date not set | Connect the STRATA_HEAT Smart LCD Thermostat to a Wi-Fi network or alternatively set the time and date from the settings menu. |
