IMPORTANT
This product operates on a new frequency of 433 MHz and is not inter-
changeable with previous 418 MHz units which can be easily identiïŹed:
433 MHz = Drayton brand
418 MHz = brand
CONFORMS TO THE ESSENTIAL REQUIREMENTS
OF THE FOLLOWING DIRECTIVES:
89/336/EEC Electromagnetic compatibility
BATTERY REPLACEMENT
30 days before the batteries need replacing, a battery
symbol will ïŹ‚ash in the right hand side of the display
(Dia. C).This signiïŹes that four 1.5V type AA alkaline
batteries will be needed to replace the existing ones.
If battery replacement is carried out in this condition
the programmed settings will only be held in the
memory for a maximum of one minute, after which
re-programming may be necessary.
IMPORTANT
To avoid the possibility of having to reprogramme the switching times and
temperatures, it is advisable to wait until the display with a ïŹ‚ashing battery
symbol changes to a continuous battery only display (after 30 days – Dia. D).
In this condition the unit will remain OFF but your programmed settings will
be held in the memory for a number of weeks.The two battery compar tments
can now be left open, to replace the batteries, for approximately one hour. If
the compartments are left open for longer, the unit will revert to the factory
preset times and temperatures. It may be necessary to reset the correct time
of day after changing the batteries.
The battery compar tments are situated at the bottom of the unit (press to
unlatch and slide down). Ensure new batteries are installed correctly. Close the
right hand compartment ïŹrst followed by the left.
HELPFUL HINTS
1. First/last set times
The Day 1 setting cannot be programmed before 12.00.The night setting
can be programmed at whatever time you require, even after 12.00
(midnight) so long as it is not programmed more than 23 hours 50 minutes
after the Day 1 setting.
2. Part or full day omission
If during programming the Digistat, one of the symbols on the left hand side of
the screen starts to ïŹ‚ash, this indicates that two or more of the switching times
have been set to the same time.This facility enables you to omit one or more
of the switched periods. When one or more switching times are programmed
together the later setting takes precedent. For example, if all four switching
times were set together the Digistat would control continuously at the fourth
(night) temperature setting .
3. Programme sequence
The Digistat will not allow you to program the switched periods out of
sequence but will hold the times together as stated above.
4. Reset
If at any time during the programming you get confused and would like to start
the procedure from the beginning press the SELECT and – buttons at the
same time and hold for two seconds. This resets the Digistat to the factory
preset times and temperatures shown in the table (overleaf).
5. Self revert
If during programming no button is pressed for between one and two minutes
the Digistat will revert automatically to its normal operating mode.

Digistat RF3i ‘Wireless System’
User instructions
SCR RECEIVER
INITIAL START UP
IMPORTANT: ENSURE THAT THE COMMISSIONING PROCEDURE HAS
BEEN CARRIED OUT IN ACCORDANCE WITH THE ENCLOSED
INSTRUCTIONS.
SCR (RECEIVER) NORMAL OPERATING MODE
Once the ‘Wireless System’ has been commissioned, there should be little need
for any user interface with the SCR.
During normal operation the red and green LEDs will occasionally be on,
these signify the following:
Green LED
The green LED will be on when there is a demand for heating, and off when there
is no demand.
Red LED
The red LED will ïŹ‚ash for 7 seconds, approximately every 5 minutes.This denotes
that a radio signal is being received from the Digistat RF unit.
SITUATIONS REQUIRING ATTENTION
Red LED continually ïŹ‚ashing
This denotes that the batteries in the Digistat RF unit are approaching the end of
their life (see ‘battery replacement’).
Red LED continually on
This denotes that the SCR has been unable to receive a radio signal from the
Digistat RF unit. This may be caused by the batteries being dead (see ‘battery
replacement’) or some temporary interference with the radio signal.
To re-send and test the signal, go to the Digistat RF unit. If the ïŹ‚ame symbol
is visible on the display, press the ‘–’ button until it disappears. If the ïŹ‚ame symbol
is not visible, press the ‘+’ button until it appears. If the radio signal has been
successfully transmitted and received, the red LED will ïŹ‚ash for 7 seconds then
go off. If the red LED is still on, ‘learn mode’ may have been selected by accident
(SCR buttons 1 and 2 pressed simultaneously).To correct, open both RF battery
drawers and wait for the display to fade, close the right hand drawer followed by
the left and reprogramme RF with your desired time and temperature settings.
If the red LED is still on, there may be some other fault that will require the
attention of a heating engineer/electrician.
MANUAL OVERRIDE
The heating can be manually switched on and off by using the ‘OVERRIDE’ button
on the SCR in a fault situation, even though the red LED will stay on until a
satisfactory signal is reinstated.
Once the SCR receives a satisfactory signal again, it will automatically reset
itself for normal operation.

OPERATING MODES
The Digistat can be operated in one of three modes.
1) – Timed, all preset times and temperatures
2) – Continuous night temperature (useful for low limit temperature
protection when on holiday)
3) – Continuous ‘DAY 1’ temperature
Use the SELECT button to change the operating mode to suit your
requirements, the symbols are positioned on the right hand side of the display.
TEMPERATURE OVERRIDE
If at anytime during normal operation, you wish to temporarily increase or
decrease the set temperature use the + or – buttons to change to your
desired setting. This can be done without entering the SET mode. 5 seconds
after releasing the + or – button the display will revert to showing the actual
room temperature. The Digistat will now control the temperature to the
override setting until the next programmed switching time, when it will revert
to the times and temperatures you have already programmed.
The Digistat RF3i features unique self learning optimum start software. They can
help achieve savings in excess of 10% on heating costs and reduce CO
2emissions,
by delaying the start time on milder days without affecting your comfort level.
USER INSTRUCTIONS FOR OPTIMUM START
There is no extra programming involved. The self learning software is factory
preset and will start to monitor and adjust the heating start times for setting ,
as soon as the unit is installed.
The optimum start feature only operates on the ïŹrst switching time of each
day ( ). Switching times , and switch at the programmed times
without any delay.
The delay period can vary between 0 - 60 minutes depending on:
a) The actual room temperature at the ïŹrst switching time ( ).
b) The set temperature of the Digistat RF3i.
c) The stored data on how fast the heating system responded the previous day.
During normal operation the ïŹ‚ame symbol on the display indicates the
current operating status.
Flame on = heating on
No ïŹ‚ame = heating off
FIashing ïŹ‚ame = saving energy (optimum start cycle operating)
When the ïŹ‚ame is ïŹ‚ashing, the optimum start cycle can be overriden by pressing
the + button once.This returns the unit to normal operation.
IMPORTANT
Always set your heating to the time that you would normally wish it to start
allowing for the coldest weather conditions. Optimum start will automatically
delay the start time and save you money on milder days.
