5.3.4.1 Configure Installation Parameters

This section describes the settings related to the wirings.

Wiring Settings

The wiring settings are used to control the software state of the relays and define the supported functions.

Configure by ToolBox
  1. On the homepage of ToolBox, click Setting to enter the Setting page.
  2. On the top bar, select Device tab.

  3. On the Installation page, enable the wire terminals that match the wirings during the installation.

  4. Select the Power Setting as RC Only or RC&RH the same as the settings during the installation.

  5. Select the options according to the HVAC system.
    Parameter Wire Description
    Reversing Valve O/B Switch the O/B mode of a heat pump or PTAC.

    Energize on Cool: O/B relay closed=cool (default)
    Energize on Heat: O/B relay closed=heat
    Heating System W1/W2/AUX/E+G Select a furnace or boiler.
    Fan Control during Heating Select Thermostat or Furnace/Boiler.
  6. Click Write in the lower right corner, and put the NFC detection area of the phone close to the NFC antenna of device. If the configuration succeeds, the following page is displayed.

Configure by Downlink

Result

By default, the thermostat will use the following control stages according to the enabled wires:
Control Stage Used Relay in Conventional System Used Relay in Heat Pumps/PTAC
Stage-1 Cool Y1 Y1
Stage-2 Cool Y2 Y2
Stage-1 Heat W1 Y1 (+O/B)
Stage-2 Heat W2 Y2 (+O/B)
Stage-3 Heat / W1
Stage-4 Heat / W2

Custom Temperature Control Stage

The thermostat can customize the used relays for every stage if the default settings do not match your requirements.

Prerequisites: Wiring Settings is configured.

Configure by ToolBox
  1. On the homepage of ToolBox, click Setting to enter the Setting page.
  2. On the top bar, select Device tab.

  3. On the Installation page, enable Custom Temperature Control Stage.

  4. Click Edit to navigate to the control stage page.
  5. Select the temperature control mode on the top bar, then click Add to add the supported control stages, and select the relay for every stage. The thermostat supports up to five heating stages, three cooling stages and one EM heat stage.

  6. Click Save.
  7. Click Write in the lower right corner, and put the NFC detection area of the phone close to the NFC antenna of device. If the configuration succeeds, the following page is displayed.

Auxiliary Heating Duration

The device supports limiting the auxiliary heating time to save energy.

Prerequisites: AUX is selected in Wiring Settings.

Configure by ToolBox
  1. On the homepage of ToolBox, click Setting to enter the Setting page.
  2. On the top bar, select Device tab.

  3. On the Installation page, enable Auxiliary Heating Duration and configure the duration value.

  4. Click Write in the lower right corner, and put the NFC detection area of the phone close to the NFC antenna of device. If the configuration succeeds, the following page is displayed.

Result
When current temperature does not reach the target temperature even after heating for the auxiliary heating duration, report an Auxiliary Heating Timeout Alarm packet and switch back to lower stage heating mode.

Compressor and Auxiliary Heat Linkage

This feature is only for heat pump systems. After enabled, when the highest heating stage of compressor (Y1 or Y2) is not able to reach the target temperature, the device will use AUX heat first. Example:
Heating Stage 1-stage 2-stage 3-stage 4-stage
Disable linkage Y1+O/B Y2+O/B W1 W2
Enable linkage Y1+O/B Y2+O/B Y2+O/B+AUX W1

Prerequisites: Custom Temperature Control Stage is disabled, and Y1/Y2 + O/B + AUX are selected in Wiring settings.

Configure by ToolBox
  1. On the homepage of ToolBox, click Setting to enter the Setting page.
  2. On the top bar, select Device tab.

  3. On the Installation page, enable Compressor and Auxiliary Heat Linkage.

  4. Click Write in the lower right corner, and put the NFC detection area of the phone close to the NFC antenna of device. If the configuration succeeds, the following page is displayed.

Emergency Heating Duration

The device supports limiting the emergency heating time to save energy.

Prerequisites: E is selected in Wiring Settings.

Configure by ToolBox
  1. On the homepage of ToolBox, click Setting to enter the Setting page.
  2. On the top bar, select Device tab.

  3. On the Installation page, enable Emergency Heating Duration and configure the duration value.

  4. Click Write in the lower right corner, and put the NFC detection area of the phone close to the NFC antenna of device. If the configuration succeeds, the following page is displayed.

Result
When the device operates in EM heat for longer than the duration, report an Emergency Heating Timeout Alarm packet and switch back to normal heat mode.

Freeze Protection

The device supports switching to EM Heat or Heat system to avoid freezing when detecting that the ambient temperature is too low. This feature takes effect even when the system is off.

Prerequisites: Heat or EM Heat is supported. If both are supported, EM Heat will be used first.

Configure by ToolBox
  1. On the homepage of ToolBox, click Setting to enter the Setting page.
  2. On the top bar, select Device tab.

  3. On the Installation page, enable Freeze Protection and configure the protection temperature.

  4. Click Write in the lower right corner, and put the NFC detection area of the phone close to the NFC antenna of device. If the configuration succeeds, the following page is displayed.

Configure by Downlink
Result
When the device detects that the ambient temperature is lower than protection temperature, it sends a freeze protection trigger packet and starts EM heat.

When the device detects that the ambient temperature is higher than freeze protection temperature, it sends a freeze protection release packet and switch to the previous status.

System Protection

The device supports enabling system protection to avoid frequent switches. After enabled, the relay can only be switched after a specific time.
Note: This does not take effect when switching between GH and GL.

Prerequisites: Either Y1/Y2/W1/ W2/AUX/E/ G is selected in Wiring Settings.

Configure by ToolBox
  1. On the homepage of ToolBox, click Setting to enter the Setting page.
  2. On the top bar, select Device tab.

  3. On the Installation page, enable System Protection and configure the minimum running duration.

  4. Click Write in the lower right corner, and put the NFC detection area of the phone close to the NFC antenna of device. If the configuration succeeds, the following page is displayed.

Y2/W2 Auxiliary Mode

By default, Y2 and W2 work in standalone mode. The device supports switching Y2 or W2 to auxiliary mode. Example:

Heating Stage 1-stage 2-stage 3-stage 4-stage
Y2/W2 - standalone Y1 (+O/B) Y2 (+O/B) W1 W2
Y2 - auxiliary mode Y1 (+O/B) Y1 + Y2 (+O/B) W1 W2
W2 - auxiliary mode Y1 (+O/B) Y2 (+O/B) W1 W1 + W2
Y2 and W2 - auxiliary mode Y1 (+O/B) Y1 + Y2 (+O/B) W1 W1 + W2

Prerequisites: Custom Temperature Control Stage is disabled, and Y2 or W2 is selected in Wiring Settings.
