Fully Pumped or Gravity System
The installer will have set the programmer to suit the installed system. This is normally a Fully Pumped system which will allow independent control of the central heating and hot water, however on an old Gravity system the central heating and hot water are linked so it is not possible to use the central heating independently. This will allow only one common time setting for both hot water and central heating and will become apparent when setting the ON and OFF times as both will be indicated together.
Manual Overrides
BOOST FUNCTION – 1-hour temporary override (HOT WATER ONLY)
The boost facility will allow the user to boost the hot water channel which is currently ‘OFF’ for 1 hour. To indicate the boost being activated BOOST will be shown on the display for the duration of the boost period. The hot water channel ON indicator will also be illuminated.
Advance Function – Brings forward the next on or off operation (CENTRAL HEATING ONLY)
The advanced facility will allow the user to switch the central heating channel ‘ON’ which is currently ‘OFF’ or switch the central heating channel ‘OFF’ which is currently ‘ON’. To indicate the advance feature being activated ADVANCE will be shown on the display until the next program switching time. The central heating ON indicator will also be illuminated.
Program Override Facilities
With the ServicePlus S27R programmer operating in the normal running mode, it is possible to alter the functionality of the program on each individual channel by means of the CH and HW buttons.
The options include;
| Auto | The program follows all programmed ‘ON’ and ‘OFF’ times. |
| All-day | Channel operates from 1st ‘ON’ time until 3rd ‘OFF’, ignoring all switching times in between. |
| 24hrs | Channel will be constantly ‘ON’. |
| Off | Channel will be constantly ‘OFF’, there is the ability to turn off the heating during the summer without altering the program times. On the hot water channel, the boost is still available. As both channels are totally independent it is possible to have them set differently if necessary. |
All of the settings above will be permanent, i.e. unaffected by program times, until alteration by the user.
The diagram below illustrates how to alter the setting, it assumes that the channel is in the AUTO mode, to begin with.
Setting Time of Day and Date
The ServicePlus S27R programmer has a built-in clock and calendar. This will mean that you will need to enter the date as well as the time on the initial set up or if the factory re-set has been used. Having done this, the clock will automatically adjust for BST/GMT time changes throughout the year.
Setting the On and Off Times
To alter these settings please proceed as follows:-
Default Time settings
| 1st ON | 1st OFF | 2nd ON | 2nd OFF | 3rd ON | 3rd OFF |
| 6.30 AM | 8.30 AM | 12.00 PM | 12.00 PM | 4.30 PM | 10.30 PM |
The default time settings shown above are preset at the factory
NB. The factory default settings for the 2nd ON/OFF times are both set at 12:00pm (midday) which cancels this ‘ON’ period giving 2 ON/OFF periods for the day. If a midday period is required set the 2nd ON and OFF times accordingly. If not press ENTER twice.
Resetting the Programmer Electronic equipment can in some circumstances be affected by electrical interference. If the programmer’s display becomes frozen or scrambled; or if you wish to revert back to the default time settings please reset by pressing the SET and CH buttons together as shown below.
After initial installation it is advisable, before programming the ServicePlus for the first time, to reset the unit. Resetting can only be achieved with the power ‘ON’ by pressing the SET and CH buttons together. This will return the programmer to the factory set default times.
