temperature as recommended by the cylinder manufacturer, in many cases for mains
pressure steel lined cylinders this is 65 to 70
O
C. The max
temperature is always greater than
the max
temperature. If when reducing the max
temperature it will not reduce any further,
it is probably because the max
temperature needs to be reduced first.
6.
Press the right hand arrow and max
75
o
C shows on the display, this is the
temperature at low level in the cylinder that the pump will be stopped at to prevent the water
in the cylinder being heated to a higher temperature. You can change this temperature by
pressing the down arrow, the temperature will blink, now press the left and right arrows to
change the temperature, now press the up arrow to select the temperature.
7.
Now press the right hand arrow, max
70
o
C is displayed on the screen. This
temperature needs to be changed to being 5
o
C less than the temperature selected in point six
above. This is done by pressing the down arrow, the temperature blinks, now use the left and
right hand arrows to change the temperature and press the up arrow to select the required
temperature.
8.
Now press the right hand arrow, max
2 is displayed on the screen, . This temperature
needs to be changed to being below the manufacturers maximum recommended
temperature. This is done by pressing the down arrow, the temperature blinks, now use the
left and right hand arrows to change the temperature and press the up arrow to select the
required temperature.
9.
Now press the right hand arrow, max
2 is displayed on the screen. This temperature
needs to be changed to being 5
o
C less than the temperature selected in Step Number Eight
above. This is done by pressing the down arrow, the temperature blinks, now use the left and
right hand arrows to change the temperature and press the up arrow to select the required
temperature.
10.
Now press the right hand arrow, diff
8.0K shows. When the sensor in the solar
collector senses a temperature 8
O
C greater than the lower cylinder temperature the pump is
turned on. This value should be reduced to 5
o
C. This is done by pressing the down arrow,
the temperature blinks, now use the left and right hand arrows to change the temperature
and press the up arrow to select the required temperature.
11.
Now press the right hand arrow and diff
4
o
C shows on the display. When the sensor
in the solar collector senses a temperature 4
o
C greater than the lower cylinder temperature
the pump is turned off. This value should be reduced to 3
o
C. This is done by pressing the
down arrow, the temperature blinks, now use the left and right hand arrows to change the
temperature and press the up arrow to select the required temperature.
12.
Now press the right hand arrow and A Auto shows on the display. This is the
automatic control mode and should be left alone. If ON is selected with a hand at low level
the pump is switched on permanently, if the OFF is selected the pump is switched off
permanently.
