Initial wiring
•
The reverse of the front plate has a wiring diagram, however remember that when the
front cover is flipped over, this diagram is shown as the opposite to the connections
on the back plate.
•
The temperature sensor with the pink cable is sensor number 1 and shall be installed
in the immersion socket on the top of the solar collector. The cable to this sensor may
need to be extended, this shall be done using 0.75mm
2
2 core Trurip cable as supplied.
Sensor number 2 is to be located measuring the water temperature at the bottom of
the cylinder, sensor number three is installed to measure the temperature in the top of
the cylinder. This is useful if the cylinder temperature is to be limited below a preset
temperature.
•
Connect the 2 temperature sensors to the terminals on the back plate. Sensor number
1 utilises the lower two terminals. Sensor number 2 the next two terminals up. If three
sensors are to be installed, sensor number 3 shall utilise the earth from sensor number
2, i.e. combine one wire from sensor 2 and 3 into the 4
th
terminal up and then the
remaining wire from sensor 3 is in the 5
th
terminal up .
•
Connect the pump to the connections as detailed on the reverse of the front plate.
•
Connect the mains supply to the connections as detailed on the reverse of the front
plate.
•
Recheck all terminations for correct location and good practice termination.
•
Plug in and switch the controller on. The controller will go through its checking
process and then display the temperature as sensed by sensor number 1.
•
If any of the temperature readouts are 999 then remake all the connections on that
sensor cable.
•
Left and right hand arrowed buttons can be used to scroll through the displays, i.e.
sensors 1, 2, 3 or the programming menus. If sensor number 3 is not installed it will
display 999
o
C, this is normal.
Programming
When programming, if no buttons are pressed for a predetermined length of time, the controller
leaves the programming menus and reverts back to the normal display of the temperatures being
sensed. You will then have to go back into the programming menu entering the CODE passwords
as required.
During normal use the left and right hand buttons are used to scroll through the different
temperatures and the fault diagnosis screen. The up and down buttons are only used to enter
programming on the ENTER
Par
and the ENTER
Men
screens During the programming the buttons
are used in the following manner. The user presses the down arrow to select a value to change, one
press of the down arrow will make the value flash, meaning that the value can be changed by
pressing the left and right hand buttons, the left to reduce and the right to increase the value. Once
the correct value is showing, a single press of the up arrow will select and confirm the value, the value
will now stop flashing.
