How To Flashing zync 99
hi, i'm mike madewell from the technicalsupport department. and in this section, we'll be talking about how to connect,configure and program a solar sync sensor to the i-core controller. the newest version of the i-corecontroller is capable of programming the solar sync settings right from thecontroller. therefore, you don't have to install acomplete solar sync kit. all you need is a solar sync sensor. you can use either a wired solar sync or a wireless solar sync sensor. the solar sync sensor measures solarradiation and temperature,
and it is also equipped with a rain andfreeze sensor. therefore, it is important that the sensor isplaced in a location where it can receive full sunlight and receive natural rainfall. based on thereadings collected, it will adjust the run times using theseasonal adjustment function of the controller. because the solar sync only changes or adjusts the stationrun time, we need to start out initially with a run time selected that'sindicative of the hottest time of the year.
in order for solar sync to take over theseasonal adjustment duties, we need to program the controller so theseasonal adjust is set via solar sync. to do this, turn the dial toset seasonal adjustment. the default is that the adjustment is done manually perprogram affecting all the stations within the program. if you press the plus (+) button while prgglobal is flashing, you will have the opportunity to program adifferent percentage by month. however, since we want to delegate thisfunction to the solar sync, we need to press the plus (+) button oncemore to choose by solar sync.
we need to do this to every programunless you want to program some stations in a program and leave them out of the control ofsolar sync. the wired solar sync comes with 40 feet or 12 meters of wire, but you can extendit up to 200 feet or 60 meters, using 18 awg 1mm wire. the wireless version consists of awireless sensor and a sensor receiver, and they cancommunicate over a maximum distance of 800 feet or 240 meters line-of-sight.
the sensor or the sensor receiver isconnected directly to a set of sensor terminals in the wiring cabinet: s1 or s2 or s3. the order of the wiresdoes not matter. it is important though that you removethe jumper that connects the two screws. also, if no sensor is connected to one ofthe terminals, the jumper must be in place. after connecting the sensor, we need toconfigure it so the controller knows what we have attached.
turn the dial to advanced features. use the down arrow button to selectsensor configuration and press the plus (+) button to access it.you will see the three sensor inputs corresponding to each of the three sensor terminals. if you have the plastic wall mountversion, you will see two sensor inputs. since we connected our solar sync sensorto the first set of sensor terminals, then we will need to configure sensor 1as solar sync using the plus (+) or minus (-) button. we will leave the other sensor inputs alone since we have nothing connected there.
once the solar sync is configured, we need to check the sensor to make surethat there is good communication between the sensor and the controller. we do this by turning the dial to setsensor operation. here, we get to choose whether we wanteach station to acknowledge the sensor status or not. a check mark next to the sensor inputindicates that the station will respond to the sensor and shut down irrigation when needed. a blank line indicates thatthis particular station will ignore the
status of this sensor. the default is that all stations willrespond to the sensor. however, if you want, for instance,stations 3 and 4 to ignore the rain and freeze inputs, then we need to advance to station 3using the right arrow button and press the minus (-) button to cancel thesen 1 which corresponds to solar sync rainand freeze alarms. we advance to station 4 and do thesame. once the solar sync sensor is configured,
we need to check the sensor to ensure agood connection between the controller and the sensor. to do this, turn the dial to solar sync settings, press the down arrow button to selectcheck sensor and press the plus (+) button. if thecommunication is successful, the display will read ok. if it detects aproblem, the display will show sensor failed and you will need to check yourconnections. the clear et history would only be usedif you had a solar sync connected for awhile and you wanted to erase
any previous evapotranspiration readings. you can do this by selecting clear et history using the up or down arrow buttons andwhen you press the plus (+) button to access it, the display will prompt you to holdthe plus (+) button to confirm that you want to clear thehistory. so once we have checked the sensor and configured it in the controller, we're now ready to program the region andthe water adjustment. to do that, we'll want to choose the region out of the owner's manual.consult the table that's listed here in
the manual and you'll select the region that bestdescribes your area. there are three ways of choosing the region. the first and most reliable method isaccording to the average et or evapotranspiration rate forjuly or whatever the hottest month of the year is in your area. you can usually find this information onthe internet. another method is according to the average temperature for july or whateverthe hottest month is.
the third method is according to ageneral description of the area you live in. to change the region, press the plus (+) or minus (-) button. the water adjustment is the other settingyou need to program. it is a 1 through 10 scale that allows you to adjust up and down in case you are over-wateringour under-watering. upon installation of the solar sync sensor, it is recommended that you leave thewater adjustment set to 5
so that you can adjust up or down from there. in fact, once you set up your solar sync sensor, you'll want to monitor it for a few days to make sure it's not over-watering orunder-watering. so if you notice the seasonal adjustment percentage is toolow for the weather condition and that all your landscape areas need a little bit more water, you can increase the water adjustmentscale. likewise, if you feel like the percentage is too highand your landscape may not need as much water, then you need to decrease the wateradjustment level. this change will be
reflected immediately under seasonaladjustment. however, if you still believe that thisadjustment was not enough, you may have chosen the wrong region tobegin with. if you feel like your entire landscapestill needs more water, you may need to decrease the regionnumber. if you need less water, you may need to increase the regionnumber. so by decreasing the region number, it'llactually increase the amount of water. by increasing the region number, it willdecrease the overall amount of water. that may sound contradictory, but it isall based on the expected
evapotranspiration for that region. therefore, since a low region number,such as a coastal region, expects to see low evapotranspiration rates, when the solar sync detects a certain etrate such as .15 inches, it may almost be at the top of its range.so it will think that it is very hot for its region and will increase the run times. a high region number such as a desertregion, expects to see high evapotranspirationrates.
therefore, when it reaches the sameevapotranspiration rate of .15 inches, this rate may barely represent halfof the expected rate for this region. so it will think that it is not hotenough and it will reduce the run times. the water adjustment and the region shouldonly be changed if all the stations need more or less water.if it's only a few individual stations, simply add or subtract run time for those zonesindividually. so next we'll talk about the solar syncdelay and this is a function that allows you to set up all your selections in thesolar sync,
but not have it become active until thenumber of days that you've chosen. if you want to program a solar sync delay,turn the dial to advanced features and press the down arrow button multipletimes until you select solar sync delay at theend of the second page. press the plus (+) button to access it andhere you will be able to set a delay from 0 to 99 days, before the solar sync takes over control ofthe seasonal adjustment. during this delay, you can tell thecontroller what percentage you want the seasonal adjustment to run at.
this feature is useful when you have anewly planted landscape and you want the grass to establish before solar sync takescontrol. for example, you could set the delay to30 days and set the percentage to water duringthe delay to 90%. after the 30-day grow and delay runningat 90%, the solar sync adjustment would take over and adjust watering for the localconditions. so this concludes the solar sync setup in an i-core controller. for more detailed questions, please referto the owner's manual which can be found
