What is an individual schedule?

The peak hours / off-peak hours schedule automates the operation of your device from Monday to Sunday, based on the rates in your electricity contract.

Generate it automatically from your hours or modify it manually if necessary.

Prerequisite: The electricity contract

The prerequisite for creating this schedule

If you want to generate an automatic schedule based on your peak and off-peak hours, you must enter your electricity contract in the Enki app, and it must include peak and off-peak hours.

If you try to generate the schedule without entering an electricity contract or with a contract that does not include off-peak hours, you will see the following message:

  • "We need the peak hours / off-peak hours information from your contract to generate this schedule"

 

To get help linking your electricity contract, you can follow the article How does my electricity contract work in the Enki app?

These time slots define when the device turns on during off-peak hours and turns off during peak hours.

 

You can modify your schedule if you wish. However, this is not recommended because the schedule is based on the hours specified in your contract. To find out which procedure to follow, see the article How does the individual schedule for my connected on/off receiver for water heaters work? The steps are similar.

It is important to choose a clear name so that you can immediately identify the schedule it refers to.

How to refresh your schedule

01. On your device settings page, click “HP/HC schedule”.

02. Click the "Refresh" button. The following message appears:

"You are about to refresh your schedule with the HP/HC data from your currently entered contract. Do you want to continue?"

If you click “HP/HC schedule” again, you will see the changes.

Refreshing the schedule restores the peak and off-peak hours configuration specified in your electricity contract. Therefore, if you have manually modified your schedule or changed your contract and it includes different time slots, this operation lets you automatically and easily apply the corresponding hours.

Force heating

How do I force heating during the schedule?

When your device is configured to use “HP/HC schedule”, a button called “Switch to Boost” appears below the “Control type” tile. Clicking this button activates forced operation of your device for 02:00.

By clicking “Boost until XX:XX”, you can change the end time of forced operation for your device.

Your device will then switch to the state specified by your “HP/HC schedule”.

Things to know about HP/HC schedules:

What does HP/HC mean?

What account information is the HP/HC schedule based on?

Flèche Enki 20px.png The schedule is based on the electricity contract you entered. It must include peak and off-peak hours. To learn how to add your electricity contract to your account, see the article How does my electricity contract work in the Enki app?

How many setpoint changes can I apply per day?

Flèche Enki 20px.png You can make up to 20 time changes per day in the schedule.

09 - Comment fonctionne un planning individuel - Message d'erreur - Nombre de plage supérieur à 20.png

When editing your schedule, you can exceed 20 time slots, but when saving, an error message appears:

  • "At least one of the days in your schedule exceeds the limit of 20 time slots"

You must therefore reduce the number to a maximum of 20 time slots per day to save.

Can the HP/HC schedule be deleted?

Flèche Enki 20px.png No, the schedule cannot be deleted; you can only refresh it.

How do I refresh an HP/HC schedule?

Flèche Enki 20px.png To refresh a schedule, go to your device settings, click the HP/HC schedule, and then select the “Refresh” button.

What is the purpose of refreshing an HP/HC schedule?

Flèche Enki 20px.png Refresh the schedule to automatically restore the peak and off-peak time slots specified in your contract, especially after a manual change or offer change.

Can I give my HP/HC schedule the same name as one of my regular schedules?

Flèche Enki 20px.png Yes, this is possible, but we do not recommend it because it could cause visual confusion.

Can my device be controlled through the “Heating” menu?

Flèche Enki 20px.png No, this is not a heating device, so it cannot be controlled through this menu.

How do I change the state of my device during the HP/HC schedule?

Flèche Enki 20px.png Simply click the “Switch to Boost” button. The device will then operate in forced mode for two hours.

Can I change the duration of Boost mode?

Flèche Enki 20px.png Yes, by clicking “Boost until XX:XX”, you can customize the time when the device should stop forced operation and switch to “Off” mode.

Can I manually turn off the device through the app when it is in an on time slot of my HP/HC schedule?

Flèche Enki 20px.png When the selected control type is “HP/HC schedule”, it is not possible to stop forced operation of the device. To stop heating, select the “Off” control type.

If you do not restore the “HP/HC schedule” control type, your device will no longer follow the schedule and will remain constantly off.
