External enable signals can be configured directly in Configuration/1:

Open

For more details on input configuration, see https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258777797.

Heat/Cool enable channel

This parameter allows you to specify which digital input of the System is used as external signal for enabling the Heating and/or Cooling function.

If the enable signal is configured, it contributes, together with other factors, to the activation of the system (see https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258778099).

System enable channel in Summer

This parameter allows you to specify which digital input of the System is used as external signal for enabling the system in cooling mode (summer).

Closing the contact also sets the system’s Current Season to Summer, and therefore the System will operate in Cooling mode.

If the Summer mode enable signal is configured, it contributes, together with other factors, to activate the system and determine the Current Season (see https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258778099).

System enable channel in Winter

This parameter allows you to specify which digital input of the System is used as external signal for enabling the system in heating mode (winter).

Closing the contact also sets the system’s Current Season to Winter, and therefore the System will operate in Heating mode.

If the Winter mode enable signal is configured, it contributes, together with other factors, to activate the system and determine the Current Season, (see https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258778099).

Select Season Channel

This signal allows you to specify which digital input of the System is used as external signal to determine the system’s Current Season.

If the Current Season selection signal is configured, it contributes, together with other factors, to determine the Current Season (see https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258778099).

CMV enable channel

This signal allows you to specify which digital input of the System is used as external signal to determine the enablement of the CMV (Controlled Mechanical Ventilation)

For more information about the CMV function, see https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258779044.

Warning

Once external enabling channels have been defined for system ON/OFF and/or season change, it will no longer be possible to change the season or switch the system on/off from the touch screens, app, or via web.

Note

DHW also has its own external signal enable command (see https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258779972)
