3.5.2 BOOST OPTION11 Pressing and holding the key for 4 seconds will select the boostoption.2 Pressing the key allows you to activate the boost function.3 Pressing the key allows you to cancel the boost function.Note: This option will only operate if the timer temperature parameters havebeen programmed for A1, (auxiliary output 1). The unit will choose themaximum temperature which has been programmed for A1, [i.e. 45°C inthis example, as 45°C (timer 1) > 40°C (timer 3)].The auxiliary output will remain switched on until:(a) the appropriate tank sensor ( in this example) has reached 45°C, or(b) a one hour period has elapsed.If no times have been set when the key has been pressed, the unit willdisplay the message: “BOOST UNAVAILABLE PLEASE REFER TOMANUAL”If this screen is displayed, then any one of the following reasons will preventthe boost function from being activated:(1) AUX 1 Relay has been manually switched off (see section 3.7, page 20).(2) AUX 1 Relay has been manually switched on (see section 3.7, page 20).(3) A1 timer temperature has not been set.(4) A1 Relay has not been selected.(5) A1 timer is already running.TIMER 1TIMER 2TIMER 317
3.6 SOLAR HISTORY - COLLECTOR, TANK AND ENERGY COLLECTED2131 SOLAR HISTORY Function selectorPressing this key once reveals the solar history screen. The SMT 400 recordsthe collector and tank temperature of each day as well as the energycollected. The storage capacity of the SMT 400 is approximately 2 years.When the memory is full the oldest data in the databank will be overwritten. Asample is taken every 10 minutes from each of these readings. These arethen displayed in graphical form, thereby representing the systemperformance for the user with clarity. A calendar allows the user to choosethe day of which data will be plotted. The unit also records daily readingsfrom the last 8 weeks, which is also plotted and can be viewed by pressingthis key twice. Pressing this key three times will display the directory of thememory bank. The highlighted months on the screen are the months forwhich the databank contains data. To view the plot of a particular day, selectthe required month from the calendar using thekeys, followed by thekey to accept the selection. A second screen appears for the selection ofthe day after which the logged data of the required day is displayed forinspection.2 Collector, Tank & Energy SelectorUse the keys to select which parameter is to be displayed on thegraph.C - Collector sensor temperature.T - Tank sensor temperature.E - Energy collected.18
