Digistat RF3 ‘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 flash 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 flashing
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 flame symbol is
visible on the display, press the ‘–’ button until it disappears. If the flame symbol
is not visible, press the ‘+’ button until it appears. If the radio signal has been
successfully transmitted and received, the red LED will flash 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.
