Cable comes from the below hole: Cut the left and right plastic flaps using an
appropriate tool (e.g. knife) and break them out of the case.
Notes: the flexible wire must be fixed on the case using the clamps ⑥ provided with
controller.
2.3 Installing the pressure water level transmitter
►Wrap some sealed tape on the sensor
connector of water storage, insert sensor into
the connector of the water storage, fasten the
copper connector and screw the sensor clock
wisely, fasten it on the connector, see left
picture.
►Connect the sensor cable with controller, and
note the polarity of wire (red wire for positive
polarity, blue wire for negative polarity).
►Mount the sensor at place where is vented,
dry, no corrosion and shady possibile, water
immersing and moisture in the terminal of
transmitter cable is forbidden.
►Switch-on power to controller, open the
drainage valve D2, and wait until water flows out
from D2 continuously, then close the valve D2.
Note:
Mounting a valve D1 /D2 between pressure
transmitter and water storage for easy maintenance.

2.6 Advice regarding the installation of temperature sensors
Only original factory enclosed Pt1000 temperature sensors are approved for use with
the collector, it is equipped with 1.5meter silicon cable and suitable for all weather
conditions, the temperature sensor and cable are temperature resistant up to 280 oC,
not necessary to distinguish the positive and negative polarity of the sensor
connection.
Only original factory enclosed NTC10K,B=3950 temperature sensors are approved for
use with tank and pipe, it is equipped with 1.5meter PVC cable, and they are
temperature resistant up to 105
o
C, not necessary to distinguish the positive and
negative polarity of the sensor connection.
Sensor cables may be extended to a maximum length of ca. 100 meter, when cable’s
length is up to 50m, and then 0.75mm
2
cable should be used. When cable’s length is
up to 100m, and then 1.5mm2 cable should be used.
All sensor cables carry low voltage, and to avoid inductive effects, must not be laid
close to 230 volt or 400-volt cables (minimum separation of 10cm)
SR530F8 user manual
- 8 -
If external inductive effects are existed, e.g. from heavy current cables, overhead train
cables, transformer substations, radio and television devices, amateur radio stations,
microwave devices etc, then the cables to the sensors must be adequately shielded.
3. Commissioning
Connect the sensors, pumps or switching valves to the controller before you
switch-on the power supply! After switching on power to the controller, firstly it will
ask for to set the time of controller.
3.1 Set time/week

display screen.
►Press “+/-” button to set hour of clock
►Press “Clock” button again, Minute area“00”blinks
►Press “+/-” button, to set minute of clock.
►Press “Clock” again, week area “WE” blinks
►Press “+/-” button, to set week.

4 System description
System description:
Controller compares the temperature between collector
（T1）and storage（T2）( bottom part), if the temperature
difference（DT）rises up to the preset switch-on DT（DT
on
）
or is over it, circuit pump R1 is triggered ; and storage is
heated until DT drops to the switch-off DT(DT
off
) or when the storage temperature（T3）rises
up to its preset maximum temperature, then circuit pump R1 is ceased.
Back-up electrical heating control (Operation see paragraph 6.7)
Within a preset heating time section, if the storage temperature (T3) drops below the
switch-on temperature of heating, then back-up electrical heating (R5) is triggered; when
temperature T3 rises up to the switch-off temperature, then R5 is switched-off.
Storage water loading control:
When water height is below the minimum water height, the water loading pump R4 is
triggered to load water until water height rises up to the middle height, then pump R4 stops.
Note: T3 is an optional sensor, when no T3 sensor is installed in the system (no connection
to input port); controller will use the signal of temperature T2 automatically to control the
back-up heating or circulation.

four times to access main menu.
5.2 DT Temperature difference
Description:
Solar circuit pump R1 is triggered by the temperature difference function, so long as the
temperature difference between collector and storage reaches the switch-on DT, solar
circuit pump is triggered.
For example: the switch-on DT is 8oC, switch-off DT is 4oC, if the temperature on the
bottom part of storage is 20oC, then just when collector temperature rises up to 28oC, pump
is triggered, and when collector temperature drops to 24oC, pump is ceased.
Note: the switch-on/off DT of 8 oC and 4 oC are standard system setting according to many
years’ experience, only in special application cases it needs to be changed, (e.g. longer
distance heat transferring), normally we recommend using default set. Switch-on and
switch-off DT are alternating set. To avoid mistake the minimum difference between two
temperature differences (ΔTon –ΔToff) is set as 2 oC.
Setup temperature difference:
Under standby, access main menu DT
►Press “SET” button, to access settings program of main
menu DT, “DT 1o 08 oC” displays on screen, “08 oC” blinks,
the first switch-on temperature difference can be set.
►Press “+/-” button, to adjust the value of switch-on DT,
adjustable range (OFF+2 oC）～20 oC, factory setting is 8 oC
►Press “ESC” button to exit this setting, parameter is
saved automatically.
►Press “+” button, “DT 1F 04 oC” displays on the screen,
the first switch-off temperature difference can be set.
►Press “SET” button, “04 oC” blinks
►Press “+/-”button to adjust the value of switch-off DT, adjustable range 0 oC～（ ON-2 oC），
factory set is 4 oC.
►Press “ESC” to exit menu, or wait for 20 seconds to exit automatically, the setup
parameters are saved automatically.
