How to set stop mode

Article Summary:

You can configure the stop mode via the Control Panel by accessing the zone settings page in settings and selecting the relevant zone to update. Read on further for more details. 

Introduction:

This article will go through how you can set the stop mode for your zones via the energy control panel. 

Stop Mode refers to our primarily weather compensation strategy, where we will 'stop' any heating by moving to a reduced target temperature, when the external temperature reaches a pre-determined temperature threshold. 

Navigation:

In order to configure the stop mode (the physical controls at site), you need to have access to the control panel with Site Manager level permissions - see here for more information on permissions: Permissions chart – ArcSett. 

Once you are at the panel: 

1. Select the ArcSett Logo in the top left hand corner.

2. Log in to the control panel using your 6 digit PIN.

3. Click the Logo again and choose settings.

4. Select Zone Settings.

5. For Individual zone changes, expand the Weather Compensation Settings Menu.

6. Action changes as appropriate. 

How to Set Stop Mode:

Stop mode is our weather compensation strategy. Stop mode enables the system to respond to external weather temperatures, preventing your heating from activating when the temperature outside is warm enough to maintain a reasonable temperature inside. 

We recommend leaving stop mode active as it can be a helpful tool to prevent energy from being wasted.

When you enable stop mode, it will activate once the temperature outside reaches your predetermined external trigger temperature. Once activated it will work towards the stop mode target temperature, as opposed to the regular one on the day pattern (these can be the same if you choose).

By following the navigation to the zone settings, you will see a screen like the one below, where you can alter the stop mode settings for each zone by selectin the weather compensation settings menu:

This is the view for someone with Site Manager permissions. 

Note: There is a small ? icon that will provide more information when selected on the strategy being amended. 

Demonstrating in practice

Below we are going to walk through a practice example of stop mode configuration.

By going to the browse screen on your panel and selecting a zone you will see the following information:

As you can see from the light in the bottom right - stop mode is active. If you take a look in the top left box, you can see the temperature inside the zone is 26.4°C and that the target is only 17°C, hence why it is active. We can also see that the heater output lights are off, indicating that heating is not on. 

The settings below are linked to the browse screen. We can tell this from the "stop mode target temp" which matches the current target that is being shown on the browse screen. We can also see the selected Compensation Strategy is "Stop Mode". This allows the system to utilise stop mode which matches the green light status seen on the browse screen. 

The temperature at which stop mode activated was set by the External Trigger Temperature, which we can see was 20°C.  The Stop Mode Target Temperature is the new target for that zone, which heating will be triggered to activate if the zone temperature drops below this threshold, in this case 17. 

Note: We have an inbuilt hysteresis built into the compensation strategy to stop the equipment intermittently switching on/off if the temperature is around the threshold point. 

 

Validation of Outputs:

In order to validate if stop mode has been correctly configured for your zone, you can take a number of actions:

• Firstly, check if the changes have been correctly saved in the settings: this can be done by exiting the zone settings page, then reloading the page via the navigation options, to see if any updates have successfully saved. 
• Secondly, check if the browse screen is displaying the stop mode active on warm days: This is as per the demonstrating in practise point above, check the browse screen and see if the stop mode active light is displaying. 
• Thirdly, you can check the heater on time via the charting to see if the heating is being activated or the period the external temperature threshold has been hit. 
• Finally, if you are in doubt of heater following the behaviour you can check the units themselves to see if they are still heating or have correctly switched off.
