Installer Level 1 - ELKO Matter

Setting device preset

You can preset the thermostat on the first power-on or immediately after an ex-factory reset. The thermostat will require the selection of a preset to pre-configure settings depending on what the thermostat is directly controlling, which allows the thermostat to function correctly for the intended use case. Preset selection is a manual process and all preset uses a PI* control algorithm which provides highly stable results.

*PI (Proportional and Integral) controller is a commonly used method in control systems to correct for error between the commanded setpoint and the actual value based on some type of feedback.

You can choose one preset configuration:

Preset mode	Configuration	Control type / Set point range	Cycle time** (min)
P1	Room control: Oil Boiler/Heat pump (Internal sensor only)	Room Control, 4°C ~ 30°C	20
P2	Room Control: Hydronic or Electrical Radiator/Gas Boiler (Internal sensor only)		10
P3	Room Control with floor limits: Hydronic or Electrical Underfloor with floor limits (Internal & external temperature sensing probe only)		10
P4	Floor Control: Electrical Radiator (External temperature sensing probe only)	Floor Control, 10°C ~ 40°C	10

**Cycle time: This setting determines the length of each on/off cycle of the output relay. In a cycle time, the time interval between relay cycle is based on the demand setpoint. A longer cycle time may be more appropriate for slow heating surfaces, such as a concrete floor. A short cycle time is more appropriate for faster heating surfaces, such as an electric panel heater.

Initial preset configuration

When the thermostat enters preset mode, by default “P2” flashes on the matrix LED’s if there is no external sensor connected, or “P4” if there is any external sensor connected.

Modifying the preset value

To modify the preset from default value, wake-up the thermostat by pressing any touch button and then simultaneously press "O" and "+" for 5 s to access the installer settings menu.

NOTE: If the preset is already configured and you want to change the value, reset it to the ex-factory settings before making any changes to the preset. Refer ex-factory reset.

Dot matrix display shows default preset.
Wi-Fi LED turns purple.

Then, use the + button on the thermostat to increase the preset value by 1 and the – button to decrease the preset value by 1.

For example: Pressing the + button changes preset P1 to P2, and further presses change it to P3 and P4.
Pressing the – button changes preset P4 to P3, and further presses change it to P2 and P1.

NOTE: To exit preset menu, simultaneously press "O" and "+" or thermostat will automatically exit if there is no interaction within 10 s.

Confirming the preset
Select the preset that meets your needs using the +/- buttons, and then hold the O for > 1 s to confirm the selection.

IMPORTANT: Once the preset is confirmed, the device proceeds to Installer Level 2.
Refer to Installer Level 2 to continue the configuration.
