15Remote control6 720 680 2096.4 "Priority" functionThe remote control does not have adefault temperature setting andtherefore has no default "Priority"function.The "priority" will be attributedautomatically by the first user whoselects or memorizes (on the remotecontrol or on the heater’s controlpanel) a temperature for subsequentuse (e.g. a shower).Then, when the hot water is used (e.g.for a shower), the heater's display andadditional remote control displays willshow the symbol " ".The temperature may only be modifiedusing the same buttons that set it(depending on whether the controlpanel or the remote control was used).The priority device will not have thesymbol " ".To clear a device that is locked out with the " " symbol (with no hot water running) simply:Bpress and hold both the " " and" " buttons on that device for 5seconds.The "Priority" function ends:• 5 minutes after the last use of thehot water (return to basic set up).• 2 minutes after selecting/memorizing the temperature if no hotwater is used immediatelyafterwards.Acquiring "priority”Any user can acquire "priority" forsubsequent use of hot water, asfollows:BMove the heater's main switch to theON position (I).BPress and hold " " or " " toselect the desired temperature.BPress and hold the "Program" but-ton until the symbol "Pr" appears on the remote control display.BUse the hot water within twominutes of acquiring "priority”.iTemperature cannot be memorized or changed using the heater's control panel buttons or a second remote control when hot water is in use (e.g. during a shower) The "Priority" function will automatically activate to stop another user from modifying the temperature when hot water is in use.6720680209-0902_(New Remote control).fm Page 15 Monday, January 19, 2009 8:58 AM
16Troubleshooting6 720 680 2096.5 Error messagesThis device has an error messagesystem. Any errors that the heatergenerates will be indicated by an errorcode that will appear on the display(Fig. 10, pos. 1) and by a symbolindicating a "safety block" (Fig. 10,pos. 7). The remote control will beoperative only after pressing the resetbutton on the heater and clearing theerror.To identify the type of error or if theerror will not clear, consult the heaterinstallation manual.7 Troubleshooting7.1 Replacing batteriesWhen batteries are weak, the lowbattery symbol (Fig. 10, pos. 5) willappear on the display.BRemove the two screws on the backof the remote control.BOpen the battery housing andremove the batteries, then replacewith new AA 1.5V batteries,ensuring they are inserted correctly.BClose the battery housing using thetwo screws.7.2 CleaningUse a damp cloth to clean parts of theremote control. Do not use abrasive orsolvent-based detergents.7.3 Troubleshooting1. No display on remote controlBCheck for weak or dead batteries (see section 7.1).Remote control in sleep mode.i"Priority" cannot beacquired while the hotwater tap is open.iVerify that the rubberseal is correctly fittedbetween both plastichousing parts.Warning: dead batteries must be replaced. Consequently, the manufacturer is not liable for any faults or damage caused by dead batteries.Dispose of the dead batteries properly.6720680209-0902_(New Remote control).fm Page 16 Monday, January 19, 2009 8:58 AM
17Troubleshooting6 720 680 209BSimply press any button on theremote to bring up the display.2. Remote control will not activate/ no number with rotating digitBEnsure that you are standing directlyin front of the water heater whenattempting to activate.BEnsure that no other device in thearea, such as a cordless phone, isoperating on a frequency similar tothe remote (915 MHz) and causinginterference.BDouble check all wire connectionsmade under section 4.1 or section5.1 of the remote control manual.Pay close attention to the wire con-necting the remote's PCB to theheater's main PCB.3. Remote display shows "- -" onlyBVerify the water heater's ON/OFFswitch is turned to the ON (I)position. If the water heater's displayis still blank, verify the heater isplugged into a live 120VAC/ 60Hzproperly grounded outlet.BVerify there is proper voltage to thewater heater (120VAC/60Htz).BVerify the remote is within themaximum distance from the waterheater of 98 feet.BEnsure that no other device in thearea, such as a cordless phone, isoperating on a frequency similar tothe remote (915 MHz) and causinginterference4. Error code and “ ” symbol will not clear from remoteBError codes cannot be reset byusing the remote. All errors must becleared by using the reset button on the water heater's controlpaneliIf not used for a fewminutes, the remote'sdisplay will go blank tosave the batteries.iLarge amounts of metalor concrete in thestructure may have ablocking effect on theremote's signal. Thismay alter the maximumdistance allowable fromthe water heater.BMove within directline of sight of thewater heater to see ifsignal will reconnect.6720680209-0902_(New Remote control).fm Page 17 Monday, January 19, 2009 8:58 AM
18Troubleshooting6 720 680 209• If an error code is generated immedi-ately after the installation of theremote control transceiver PCB,ensure that the two large electricalconnectors (Fig. ) on the main PCBare properly seated.• Error code may not be resettable.Consult water heater's installationmanual or www.boschpro.com forfurther troubleshooting on errorcodes.5. Remote will not memorize desired temperature settingBVerify that the remote control"program" button is depressed untilthe remote display reads "Pr".6. Priority " " symbol will not clearBVerify no hot water is being usedwhen trying to clear "priority"function.BWith no hot water running, pressand hold the “ ” or “ ”buttons for 5 seconds on the lockedout device (remote or water heater)until the " " symbol (Fig. 10,Pos. 6) disappears.BDo not use any hot water for at least5 minutes. The priority functionshould automatically clear after thistime period.iMemorization of a selected temperature only saves to the device on which it was originally programmed. To retrieve a memorized temperature setting, you must use the device with which it was programmed.6720680209-0902_(New Remote control).fm Page 18 Monday, January 19, 2009 8:58 AM
