Setting the Year, Date and Time


Press and hold the “OK” button until the display flashes, this will then show the year, day and month then the time. These can be altered using the left and right arrows and confirming your selection by pressing the “OK” button again to finalise your choice.

 

Parameter settings


The FP720 unit comes pre-set with a 5/2 day heating and hot water set up with two on/off periods each day with a 24 hour clock. If you want to change these settings to something else you will need to press the “stack” button (that’s the one with the 3 horizontal lines that looks like a stack of pancakes). Press and hold the “stack” button for around 3 seconds until the display changes to show the parameter settings. Just like altering the date and time in step 1, you can change these parameter settings using the left and right arrows and then confirming your selection by pressing the “OK” button again to finalise your choice.

 

Setting up your Heating and Hot Water


Press the “stack” button and press “OK” Mon to Fri will show up, press “OK” again to confirm then you will go through to the first on period, you can then change the hours and minutes by toggling the left or right buttons as you have done previously in steps 1 and 2. Press “OK” to confirm your selection and then repeat the process for the first off period. On the top right of the screen you will see a number which tells you what period you are in, the default setup is for four periods coming on and off in the one 24 hour period.

After you have completed the settings for Monday to Friday it will then move onto the Saturday and Sunday settings, repeat the same process and then press “OK” to finalise your preferences, this will then return you to the main screen.

Press the “stack” button and then press “CH” to switch from heating setting to the “HW” hot water setting, the hot water is set up in the same way as the previous steps for the heating function. The hot water settings also have four on/off periods, toggle through the preferences as you have done previously and then press “OK” to finalise your preferences, this will again return you to the main screen as before.

 

Central Heating and Hot Water functions


Press the “CH” button and then “CH1” will flash, you can then use the left and right arrow buttons to toggle between the different options such as: “AUTO”, “+1HR”, “ON” and “OFF”, once you have made your selection press “OK” to confirm. When referring to the different options, “AUTO” relates to the programmed on and off period which was set up in the previous steps above, and the “+1HR” brings on the heating for a one hour burst only. When the heating is running, a ‘heating’ symbol will appear on the display panel.

Press the “CH” button twice and this will now display the options of the hot water, using the same process as the heating setting above, go through the same process for “AUTO”, “+1HR”, “ON” and “OFF” and then press “OK” to finalise your settings. When the hot water is running, a ‘tap’ symbol will appear on the display panel.

 

Holiday setting


There will no doubt come periods when you will want to avoid the hot water or the heating coming on when you are away from the property, this is when the holiday function comes in handy. The holiday function will override the pre-set programme you may have setup in the steps previous. To action the holiday function press and hold the “CH” button for roughly 3 seconds, this will prompt a ‘suitcase’ symbol to appear in the top left of the display screen. When the suitcase is displayed you are now in holiday mode and no heating or hot water will be triggered to come on. To take the system out of holiday mode just press the “CH” button and normal service will resume to your heating and hot water system.
