Installing the Thermostat

Attention: Before changing the thermostat, disconnect the heating system from the mains power in your flat. This will prevent potential injury by electric current.

Placement of the Thermostat: The placement of the thermostat significantly affects its functioning. Choose a location where members of the family spend most of their time, preferably on the inside wall where air circulates freely, with no direct sunlight. Do not place the thermostat in the vicinity of heat sources (such as TV sets, radiators, fridges), or close to a door (due to frequent shocks or vibrations). If you do not follow these recommendations, the thermostat will not maintain room temperature correctly.

1. Use a screwdriver to press on the internal lock and slide out the metal frame. If necessary, carefully disconnect the internal connector joining the two parts of the thermostat together.
2. Install the mounting plate onto a suitable junction box, e.g. KU 68.
3. Connect the wires leading out of the junction box to the marked terminals on the thermostat in accordance with the wiring diagram. Reconnect the internal connector, fit the thermostat back onto the mounting plate and secure it with the metal frame.
4. Replace the front cover.

Mobile Application

The thermostat can be controlled using a mobile application for iOS or Android. Download the EMOS GoSmart app for your device.

Download on the App Store | GET IT ON Google Play

Tap the Log In button if you've used the app before. Otherwise, tap the Sign Up button and register.

Pairing with the Mobile Application & Temperature Programmes

Pairing with the Mobile Application

Long-press both the ☰ and ⏻ buttons on the thermostat simultaneously. The ? and ☁️ icons on the thermostat screen will start flashing; the thermostat is now in pairing mode.

In the app, tap "Add Device", then select "GoSmart" and tap the "Thermostat underfloor P56201BUF" icon.

Follow the on-screen instructions in the app to enter your 2.4 GHz Wi-Fi network name and password. The gateway will pair with the app within 2 minutes.

Note: If the thermostat fails to pair, repeat the entire process from the start. 5 GHz Wi-Fi networks are not supported.

Temperature Programmes

The type of temperature programme can be chosen in the Calendar Mode tab in EMOS GoSmart settings.

Types of temperature programmes:

• 5 + 2 (Mon-Fri + Sat-Sun): Allows setting a fixed temperature for 5 workdays and 2 weekend days. Up to 6 time periods per day type.
• 6 + 1 (Mon-Sat + Sun): Allows setting a fixed temperature for 6 days (Monday to Saturday) and 1 day (Sunday). Up to 6 time periods per day type.
• 7 days: Allows setting a fixed temperature for all 7 days. Up to 6 time periods per day.

Time periods can be set in the Weekly Mode Settings tab in the EMOS GoSmart app. The set temperature will be active until the next time period.

Temperature Calibration

The thermostat sensor can be calibrated to optimize accuracy. Calibration can be set in EMOS GoSmart from -9 °C to 9 °C with 1 °C resolution.

Example: Setting calibration to +1 °C will display 23 °C if the room temperature is 22 °C.

Temperature Differential

This is the temperature difference required for switching the heating system on and off (hysteresis).

• Internal sensor differential: 0.5 °C to 2.5 °C.
• Floor sensor differential: 1 °C to 9 °C (via EMOS GoSmart app).

Example: With a set temperature of 20 °C and a differential of 2 °C, heating activates when the room drops to 18 °C and switches off at 22 °C.

Temperature Limits for Manual Thermostat Settings

• Maximum setting limit: 20 °C to 70 °C (1 °C resolution).
• Minimum setting limit: 1 °C to 20 °C (1 °C resolution).

Temperature Protection

• High-temperature protection: Sets the maximum temperature the thermostat heats the system to. Example: If set to 45 °C with a 2 °C limit, the relay switches off at 45 °C and on at 43 °C.
• Low-temperature protection: Sets the lowest desired room temperature. If the temperature drops below this value, the thermostat automatically starts heating. Can be set from 1 °C to 10 °C.

Status of the Device after Reconnecting to Power after a Power Outage

• Same as before: Thermostat returns to its previous state.
• Off: Thermostat stays off.
• On: Thermostat turns on.

Active Temperature Sensor

Selects which sensor detects temperature: internal sensor, floor sensor, or both.

Child Lock

Activated/deactivated via the EMOS GoSmart app or by holding the ⬇️ button for 3 seconds. A ? icon will appear on the screen when active.

Thermostat Screen Brightness in Standby Mode

Adjustable in settings (0 = screen off, 1 = slight illumination, 2 = strong illumination).

Open Window Function

If a sudden temperature drop is detected (e.g., open window), heating stops. Heating resumes after a set time or when the window is closed. Can be set/turned off on the thermostat screen.
