Digistat RF Troubleshooting ProcedureThis data sheet is intended to help you resolve any problems you may be encounteringwith the operation and use of the Drayton Digistat RF range of products.Please follow the below steps before contacting Drayton regarding faulty product.Enclosed you will find replacement battery drawers with a new contact arrangement asper below:Old Battery DrawerNew Battery Drawer1) - Replace old battery drawers with the new battery drawersA) To replace drawers, remove digistat from wall by loosening screw underneath TheDigistat RF transmitter.B) Pull down both battery drawers until fully extendedC) Remove batteries from drawersD) Push battery drawer away from you until drawer drops out of unitInstallation of new battery drawers:A) Insert battery drawer and push until drawer clicks into positionB) Insert new batteries, ensuring they are type AA - Alkaline batteriesC) Close Drawers
2) - The system needs to be fully re-commissioned.Follow the procedure below to begin the commissioning of the system.Commissioning the Digistat R.F. SystemA) Pull down battery drawers from Digistat unit and allow screen to go completelyblankB) Turn off the power supply to the SCR receiver unit and leave for 5 secondsC) Turn on power to SCR unit and check red light is onD) Put the SCR unit into its manual override mode by pressing the override buttonNo.2 once. Check the green light comes on and that the boiler fires (Do not pressagain)E) Now, Press & hold down button No.1 (Keep depressed), then press No.2 and keepdepressedF) The Red LED light will flash a couple of times and then it will go outG) Now release both the buttons – {the two LED lights should come back on}H) Get the Digistat transmitter unit and stand two metres away from the SCR unit withthe Digistat unit in your handI) Slide in the right hand battery drawer (under the “Plus” button) firstJ) Slide in the left hand battery drawer (under the “Minus” button) secondK) The Red LED light will now flash for approx. 7 seconds to tell you that the two unitsare communicating.Put the Digistat unit back on the wall
3) - When commissioning is finished Successfully:If commissioning is successful, it is always best to check that the digistat transmitter isplaced in the optimum position for transmission of the signal to the SCR Receiver. Inorder to do this, it is important to follow the “Signal Strength Quality Test” instructionsbelow:A) Open the left hand battery drawer (draw under “minus (-)” buttonB) Wait for the screen to fade (Pressing the “ ” or “-“ buttons alternately will speed thisprocess up)C) With the “ ” button held down re-power the transmitter by sliding the left handbattery drawer back into the unitD) Observe the red LED light on the Digistat SCR unitE) The LED should be blinking with two steady short pulses and then no light for asecond and this should keep repeating itself nice and steadily. Any missed or erraticpulses imply that there is a fault with the signal path. Try changing the position ofthe transmitter and see if the quality of the signal improves.F) Once you have established the preferred position for the digistat transmitter, affix towall or suitable location and see next step.G) After carrying out this test you will need to pull down the left hand battery draweragain and wait until the screen fades again and then re-commission the units (SeeSection 2)After you have tried these three pointers, if you are still experiencing problems withthe units please do not hesitate to contact us on 0845 130 7722
