T hermostat terminals (T -T) provide a current source. Never apply external power to these terminals under any circumstances.Mounting • T he control may be mounted on a 4" x 4" junction box in any convenient location on the burner, furnace or wall. The location must not exceed the ambient temperature limit, 140°F .Wiring• Wiring must comply with local and national electrical codes, and with the wiring diagram.• Individual or bundled neutrals may be attached to any L2 terminal.Continued on next pageSmart IgnitionIMPORTANT: All four wires provided must be used to activate the Smart Ignition feature. The ignitor must be wired to the control’s blue ignitor output terminal. See Figure 1 for Smart Ignition Wiring diagramSmart Ignition runs in Intermittent Duty (aka “constant” duty) when needed to prevent loss of flame. But unlike any other primary control, Smart Ignition switches to Interrupted Duty when it can – to save wear and tear on the ignitor and electrodes.How Smart Ignition WorksThe control initially works as an Interrupted Duty control. Following the Trial-for-Ignition period and Flame Stabilization period, the ignitor output is turned off.If flame is lost at any time after the Trial-for-Ignition period, the control will recycle (60 - 65 seconds). Following this recycle, the control will operate in Intermittent Duty mode for ten heat cycles. Following these ten cycles, the control will revert back to Interrupted Duty and will remain in Interrupted Duty until another recycle event occurs. Note: If control recycles and operates in Intermittent Duty three consecutive times, on a fourth consecutive recycle the control will lockout (solid red LED ON) due to hitting smart ignition limit (30 cycles)The Best of All WorldsThe Model 48245 with Smart Ignition ensures flame retention by providing intermittent duty ignition when required to prevent flame loss and it dramatically increases the ignitor and electrode life and saves energy by switching to interrupted duty the remainder of the time.To manually reset from Intermittent Mode: Open TT and depress the reset button until the amber LED turns on. Release the reset button; the control is reset from the intermittent mode.Figure 1: 4-wire 48245 Oil Primary Control (activates Smart Ignition – see page 4 for details)Figure 2: 3-wire 48245 Oil Primary Control (does not activate Smart Ignition)WiringInstalling and Wiring (continued)Field checks 1. S elect preferred TFI by 1) leave jumperin for 45 seconds or 2) remove jumper for 15 seconds. IMPORTANT: TFI change occurs on next call for heat.2. S afety timing (TFI) test – Remove oneCAD cell wire (F-F). Start burner. Thecontrol should lockout within the TFI time limit. Replace CAD cell wire.3. F lame failure test – Start burner. Afterflame is established (after TFI period), close the oil supply hand valve. This will cause a flame failure sequence as de-scribed in the Startup & Operation section of this data sheet. Under recycle, please read “Smart Ignition” on page 4.4. I f control does not operate as described,check the wiring.2Power ON OSee below to reset.)Self-test 1T he control performs a “boot-up” test to verify internal operation each time power is applied to the black (L1) wire. The amber LED turns on and the test continues for about 5 seconds. If the test fails, the controlturns the amber LED off and repeats this test sequence until successful.Stand-by(No call for heat) If Self-test 1 is successful, amber LED turns off and control waits for heat call.Call for Set thermostat to call for heat. Thermostat circuit must be closed (and black wire must receiveheatpower from the limit circuit).Self-test 2I f a failure occurs in this self-check, the control won’t start and the amber LED blinks 1 second on, 4 sec-onds off, until serviced or the problem clears. These failures include CAD cell seeing light, internal failure,or line voltage <90V. See service section.Burner ON A fter the self-test, amber LED turns off. The ignitor starts, followed 2 seconds later by the motor. Note: Wired as 3-wire, the ignitor and motor come on at the same time.Pump To enter pump prime: 1. Start a CFH cycle. During Pre-Ignition, press Reset until motor turnsPrime o ff (10 seconds), then release the button. When motor turns back on, within 5 seconds, press the Reset button until the amber LED starts to flash. Y ou are in Pump Prime, release Reset button.O ptional Pump Prime notes: 1) If Pump Prime is lost, press Reset for 1 second and release, then if thecontrol is not in Pump Prime, restart the sequence. 2) If Reset is released before end of first 10 seconds,the control returns to Standby and restarts another CFH cycle. 3) If reset is not pressed the second time,a normal CFH cycle will continue. 4) If motor and igniter are on and amber LED is flashing, the control is inPump Prime. 5) Pump Prime will exit standby if flame is detected, or 60 seconds has elapsed, or loss ofTT or Limit, or Reset button is pressed.T he CAD cell must sense flame within the TFI time limit (trial for ignition). Insufficient flame puts control intolockout.Run T he burner continues firing during call for heat if the CAD cell is sensing flame. Only the green LED is onduring normal running.Lockout I f CAD cell does not sense flame within the TFI time limit after the burner starts, lockout occurs. The con-trol turns the red LED on constant and closes the alarm contact.To Reset Push in and hold reset button for 2 seconds, then release.The 48245 control will retain lockout if power is interrupted.Recycle If the CAD cell loses flame signal during operation (after the TFI), the Red LED flashes. Recycle:(Flame Failure)control waits for 65 seconds, Red LED goes off, then begins again at Self Test 2.If the green LED is blinking during a run, the flame is weak or unstable and may go into recycle.Stand-by C ontrol remains in stand-by mode until limit circuit sends power to the black wire and thermostat circuit closes (call for heat).Startup & OperationThree wire or four wire configuration• S ee Figure 1 on page 2 for wiring diagram for4-wire configuration (Smart Ignition)• S ee Figure 2 on page 2 for wiring diagram for3-wire configurationDo not start the burner if the combustion chamber contains oil or oil vapor.Per UL requirements, the control will not turn on if the CAD cell senses flame during the self-test.

PQ=⋅=×22244991411kk k≤−+−=++，当且仅当222449911kk k−=−++，即21k=时等号成立．当直线l的斜率不存在时，||6MN=，||PQ=此时11||||622PMQNS MN PQ=⋅=××=．当直线l的斜率为0时，根据对称性可得PMQNS=．综上所述，四边形PMQN面积的最大值为14．21．【命题意图】本题考查线面平行与线面角．【解析】（Ⅰ）如图，连接1AC交1AC于点O，连接OE，显然O是1AC的中点，因为E为AB的中点，所以OE为1ABC△的中位线，1//OE BC，而1BC⊂/平面1EAC，OE⊂平面1EAC，所以1//BC平面1EAC．（Ⅱ）设11AC的中点为1M，连接1M O并延长交AC于点M．因为BA BC=，所以1111B A B C=，于是有1111B M AC⊥．因为三棱柱111ABC A B C−是直三棱柱，所以平面111A B C⊥平面11A ACC，而平面111A B C 平面1111A ACC AC=，所以11B M⊥平面11A ACC．因为侧面11A ACC是矩形，所以111AC M M⊥．以1M 为原点，分别以直线11AC ，1M M ，11B M 为x 轴、y 轴、z 轴建立如图所示的空间直角坐标系．设(1)BA BC t t ==>，则1(1,0,0)A −，C，12E − ，于是1(2,CA =−，32CE =− ． 设平面1EAC 的法向量为(,,)n x y z = ，则有10,0,n CA n CE ⋅= ⋅=即20,30,2x x z −= −+= 令1x =，可得1,n = ． 易知平面1ACA 的一个法向量为(0,0,1)m = ． 因为二面角1E AC A −−的大小为π6，所以π||cos 6||||m n m n ⋅===t =． 故1(0,0,1)B，11)B C =−，(1,n = ．设直线1B C 与平面1EAC 所成的角为θ，则11sin ||B C n B C n θ⋅== ，即直线1B C 与平面1EAC22．【命题意图】本题考查直线与圆的综合应用．【解析】（Ⅰ）由题可知点O 在圆C 上，且圆C 的方程为2222()()x a y b a b −+−=+， 整理得22220x y ax by +−−=，则(2,0)A a ，(0,2)B b ． 所以122222AOB S a b ab =××==△，为定值．（Ⅱ）因为直线0x y −=经过圆C 的圆心，所以a b =．又1ab =，0a >且0b >，解得1a b ==．所以圆C 的方程为22(1)(1)2x y −+−=．（Ⅲ）显然P ，G ，C ，H 四点共圆，且PC 为该圆的一条直径，设这四点所在的圆为圆N ，(22,)P m m −−，则圆N 的方程为22221213212222m m m m x y +++− ++−=+， 即22(21)(1)20x y m x m y m +++−+−−=，①又圆C 的半径r =，方程可化为22220x y x y +−−=，② ①－②，得圆C 与圆N 的相交弦GH 所在直线的方程为(23)(1)20m x m y m ++−−−=．点(1,1)C 到直线GH 的距离d所以||GH ，所以当1m =−时，||GH ，故线段GH ．。
