Once the preset is chosen, press O button for 1 s to confirm the preset. Then the device continues to the Installer Level 2.

TIP: For more info on preset, refer device preset.

When you enter Installer Level 2, the Wi-Fi LED glows purple, and the left most menu level indicator glows white.

Press + or – to navigate between the menu option from 51 to 57.

Floor probe type

A thermostat with a preset value of P3 and P4 can be connected with an external floor sensor to regulate the room temperature.

After preset, you will enter floor probe type (floor sensor type) selection menu where you can manually select the sensor type connected to the thermostat; this allows the thermostat to convert and display the temperature accurately.

To select the floor sensor type:

Select menu 51 by pressing O touch button for > 1 s to enter the settings.
Press + or – touch button on the thermostat to switch between the sensor types.
Following are the available sensor type:
- 00 Not equipped with any probe
- 02 kOhm
- 10 kOhm
- 12 kOhm
- 15 kOhm
- 33 kOhm
- 47 kOhm
Select the sensor type which is installed and then press the O touch button for > 1 s to confirm the selection.

Minimum floor limit

After setting floor probe type, you must set the minimum floor limit. It is lower limit of the floor sensor.

To set floor limit:

Select menu 52 by pressing O touch button for > 1 s to enter the settings.
Press + or – touch button on the device to set the minimum limit.
Press the O touch button for > 1 s to confirm the selection.

NOTE:

The temperature limit ranges from 10° C to 39° C.
Each “+/–” tapping will increase or decrease the temperature by 1° C.
When the minimum floor limit is set, it changes the minimum floor control setpoint that can be set in the user settings.

Maximum floor limit

After setting minimum floor limit, you must set the maximum floor limit. It is upper limit of the floor sensor.

To set maximum guard temperature:

Select menu 53 by pressing O touch button for > 1 s to enter the settings.
Press + or – touch button on the device to set the maximum limit.
Press the O touch button for > 1 s to confirm the selection.

NOTE:

The temperature limit ranges from 11° C to 40° C.
Each “+/–” tapping will increase or decrease the temperature by 1° C.
When the maximum floor limit is set, it changes the maximum floor control setpoint that can be set in the user settings.

Control method

Control method used in thermostats to achieve variable heating outputs for precise control of the average power delivered to the heating system, helping to maintain the desired temperature.

To set control method:

Select menu 54 by pressing O touch button for > 1 s to enter the settings.
Press + or – touch button on the thermostat to switch between the option.
Following are the available control method:
- 01 PWM 20 mins
- 02 PWM 10 mins
- 03 PWM 5 mins
- 04 2 pt 0.5 K
- 05 2 pt 0.1 K
NOTE:
- Control method 01 to 03 works on PWM (Pulse Width Modulation) which rapidly switches the power on and off to the heating system to achieve variable output. By adjusting the width of the on and off periods, PWM controls the average power delivered to the system, effectively regulating the temperature.
- Control method 04 and 05 works on PID (Proportional-Integral-Derivative) which uses feedback to continuously adjust the output based on the difference between the desired setpoint and the actual temperature. It calculates an output value that provides both proportional, integral, and derivative actions to minimize the error over time, resulting in precise and stable temperature control.
Press the O touch button for > 1 s to confirm the selection.

2-pt min On/Off time

IMPORTANT: This parameter setting in a thermostat is only available when the control method is set to option 04 or 05.

You can set the minimum duration for which the thermostat's heating system must remain On or Off before it can switch the state (On or Off).
This feature helps to prevent rapid cycling of the system, which can improve energy efficiency and reduce wear and tear on the equipment and optimizing the performance of the heating system. When enabled, switch over takes place every hour.

To set 2-pt min:

Select menu 55 by pressing O touch button for > 1 s to enter the settings.
Press + or – touch button on the thermostat to switch between the option ranges from 1 to 10 represented in mins.

NOTE: Each “+/–” tapping will increase or decrease the value by 1.
Press the O touch button for > 1 s to confirm the selection.

Temporal limit

Enabling or disabling the temporal limit in a thermostat allows users to control whether time-based restrictions are applied to certain functions. When enabled, the thermostat will adhere to predefined time constraints for specific settings or modes, helping to manage energy usage and maintain comfort effectively. Disabling it removes these time-based restrictions, providing more flexibility in how the thermostat operates. This feature can be particularly useful for optimizing energy efficiency and accommodating various scheduling needs.

To set temporal limit:

Select menu 56 by pressing O touch button for > 1 s to enter the settings.
Press + or – touch button on the thermostat to display following option.
- : Disable
- : Enable (5 min off time)
Press the O touch button for > 1 s to confirm the selection.

Windows open detection

Windows open detection in a thermostat is a feature that utilizes sensors to detect when windows or doors are open in the room. When there is a sudden drop in temperature, the thermostat will stop heating and after 20 min, normal control will resume. This helps improve energy efficiency and can contribute to cost savings by ensuring that the system operates more intelligently in response to changes in the indoor environment.

To set windows open detection:

Select menu 57 by pressing O touch button for > 1 s to enter the settings.
Press + or – touch button on the thermostat to display following option.
- : Disable
- : Enable
Press the O touch button for > 1 s to confirm the selection.
