Two kinds of heating device(heating mode) are available: Electrical heater as
back-up heat resource (ELET) Boiler as back-up heat resource (BOIL)
Note: system 4, 14,15 has no heating mode option, when time heating function is
activated, sign
displays on the screen.
Three time – sections can be set for back-up heater Factory default set: The
first time – section of heating starts at 04:00and stops at 05:00a.m. The
second time – section of heating starts at 10:00 and stops at 10:00a.m. The
third time – section of heating starts at 17:00 and stops at 22:00 p.m. For
all time – sections, default temperature for control back-up heating is
triggered at
temperature of 40oC, and stopped at temperature of 50oC. If it is needed to
deactivate the back-up heating function in one time – section, then just
set the start time and stop time with a same value, for example, for the
second-time section, the start time is 10:00 a.m, and the stop time is also
10:00 a.m. Within three time – sections, the adjust range of the switch-on
temperature is 0oC ~(OFF-2oC), and the switch-off temperature is (ON+2oC)
~95oC.
SMT Intelligent heating At the case that solar energy is insufficient to heat
the tank, to ensure user has sufficient hot water, controller will check the
temperature of tank automatically at the pre-set time, if tank’s temperature
is not reached to the desired temperature, then back-up heat producer will be
triggered, and when tank’s temperature rises to the desired value, then back-
up heat producer is stopped.
Factory set(not adjustable) of SMT function: Default at 13:00 of the first
time to trigger the back-up heat device to heat tank to 30 oC, Default at
14:00 of the second time to trigger the back-up heat device to heat tank to 35
oC, Default at 15:00 of the third time to trigger the back-up heat device to
heat tank to 40 oC, Default at 16:00 of the fourth time to trigger the back-up
heat device to heat tank to 45 oC, Default at 17:00 of the fifth time to
trigger the back-up heat device to heat tank to 50 oC.

Note: 1. Because of the system selection, in this system, several auxiliary
functions may be allocated to the same output, for example to R2 output, (see
paragraph 4.2 system diagram and its auxiliary functions), then only one
function can be activated, other functions are deactivated automatically, and
displays “NONE”. 2. And because of system selection, the sensor and relay for
a same function may be different.
Function description: This function is designed to get warm water quickly when
customer open the stopcock. In the case stopcock is closed, hot water pipe is
also used as the circuit pipe. Two hot water circuit supply modes are
available, temperature controlled mode and flow switcher controlled mode. For
using this function, an extra circuit pump RX or a flow switcher or a
temperature sensor (mounted on the hot water return pipe (TX)) should be
installed in the system. (and due to the solar system difference, output relay
or sensor input used for circuit pump RX and temperature sensor TXmay be
different also, see detailed in paragraph 4.2)
2 control mode of DHW circuit pump are designed in this controller:
temperature control in three time sections and flow switch control in three
time sections.
This sign displays on the screen, it indicates temperature control mode is
activated. If this sign blinks,it indicates DHW circuit pump is running.
This sign displays on the screen, it indicates flow switcher control mode is

1. for 2 DHW circuit pump control modes, only one mode can be selected. 2.
for 2 DHW control modes, three time – sections/temperature control mode and
three time – sections /flow switcher control mode, their parameter adjust
steps of two control mode are same.
Three time – sections/ temperature control mode TEMP Within the time – section (default: DHW temperature is less than 40oC, DHW circuit pump is trigger, when temperature rises to 45oC, DHW circuit pump is stopped).
Trigger on conditions of temperature controlled DHW circuit pump (STAT): when tank temperature (T2 or T3) is 2oC higher than the preset switch-off temperature (CYCF) of this function, DHW pump just can be triggered.
Default time – section set: The first time – section: start at 05:00 and stops at 07:00a.m The second time – section: starts at 11:00 and stops at 13:00 The third time – section: starts at 17:00 and stops at 22:00 p.m.
Note: if this sensor is necessary to be installed in the system, in order to avoid the measure error, please ensure its position is 1.5m far to the tank.
Three time – sections/ flow switcher control mode CYCFS
Function description:
Open the stopcock, water flows through pipe, a flow signal is felt
by a flow switcher which is mounted on the cold-water pipe and
sent to the controller, and then controller will trigger the DHW
circuit pump (RX) and it pumps hot water from tank to the circuit
pipe. The running time of circuit pump is adjustable, when the
preset time runs out, pump stops.
Flow switch
This stopcock seems like a remote controller to control the
To TX input
running of circuit pump. This operation mode is an environment-friendly, energy-saving control
solution.
Open the stopcock for a shortly time, the flow switcher which is mounted on the cold flow pipe
Page 48 of 113
Downloaded from www.Manualslib.com manuals search engine
Operation manual of solar controller SR658 of tank will feel the flow signal,
and then controller will trigger the circuit pump RX, and pump will feed hot
water from tank to the pipe. Then when you re-open the stopcock, hot water
flows out immediately. Once the pump’s running time finishes,then pump is
stopped. When hot water is not used, to avoid the heat releasing through pipe
due to the running of circuit pump, controller will stop the pump after the
pre-set running time. To avoid the pump being re-triggered just after it
stopped, parameter “rest time” is used for this control.
Open the stopcock within a pre-set time – section, pump running as the default
design: pump running for every three minutes and then rest for 15minutes (the
adjustable range of the running time is 1-30 MIN and the rest time is 0-60MIN)
Note: Installed a checkvalve on the inlet pipe of circuit pump to avoid the
water which is from
tank mixing with water from circuit pipe. If the stop time is set with value 0
minute, then when flow switcher feels the flow and
thus to trigger the pump, pump will run for the whole time – section. And when
the stopcock is closed, pump is stopped automatically. Default time – section
set: The first time – section: start at 05:00 and stops at 07:00a.m The second
time – section: starts at 11:00 and stops at 13:00 The third time – section:
starts at 17:00 and stops at 22:00 p.m.
Flow switch fitting: Material of fitting: brass House: plastic Connection:
G3/4 Reed of flow switch: Max 300V DC/1A
Note: 1. Notethe flow direction indicated on the flow switch! 2. Lead the
wires from flow switcher to input ports of controller, no polarity required.
3. Flow switch is not included in the delivery list of this controller, please
buy it separately.

Tank heating set Function description:
T DT Temperature difference The controller works with a standard differential
control logic. If the temperature reaches or exceeds the switch-on temperature
difference (DTO), the pump switches on. When the temperature difference
reaches or falls below the adjusted switch-off temperature difference DTF, the
respective relay switches off.
Note:The switch-on temperature difference must be 0.5K higher than the switch-
off temperature difference. The set temperature difference must be at least
0.5K higher than the switch-on temperature difference.
Note: In systems with 2 tanks or tank loading in layers, 2 separate menus(LOAD
and LOAD 2) will be displayed.
Speed control If the temperature reaches or exceeds the switch-on temperature
difference, the pump switches on at 100% speed for 10s. Then, the speed is
reduced to the minimum pump speed value. If the temperature difference reaches
the set temperature difference DTS, the pump speed increases by one step
(10%). The response of the controller can be adapted via the parameter RIS. If
the difference increases by the adjustable rise value RIS, the pump speed
increases by 10% until the maximum pump speed of 100% is reached. If the
temperature difference decreases by the adjustable rise value RIS, pump speed
will be decreased by one step 10%.
Note: To enable speed control, the corresponding pump should be set to (MIN,
MAX) and relay control should be set to (PULS, PSOL, PHEA or 0-10 V) (under
adjustment menu PUMP).
SMAX Maximum tank temperature protection set If the tank temperature reaches
the pre-set maximum temperature, the tank will no longer be

(collector emergency shutdown). If the maximum collector temperature is exceededOCEM,
Warning iconis
displayed and code CEM displays.
Note: In systems with east- / west collectors, 2 separate menus (COL and COL 2) will be displayed. Warning! Risk of injury! Risk of system damage by pressure surge! If water is used as the heat transfer fluid in pressure systems, water will boil at 100 °C. Do not set the collector limit temperature higher than 95 °C.
OCCO(2) Collector cooling The collector cooling function is designed to keep the temperature increase of collector within the operating range by the way of heating tank. If the tank temperature reaches 95 °C, this function will switch off the pump due to safety of system.
When the tank temperature exceeds the pre-set maximum tank temperature, then
solar pump is switched off. And then collector temperature may rise, if the
collector temperature rises to its maximum temperature, the solar pump is
switched on again to transfer the energy from collector to tank, pump keeps
running until the collector temperature falls below the maximum collector
temperature, in this heating process, tank temperature may exceed its maximum
temperature, but only up to 95°C (emergency shutdown of the tank),both icons
are blinks on the screen and code LEM displays, and then pump is stopped.
If the collector cooling is activated, is displayed and code CMAX displays.
This function is only available when the system cooling function (OSYC) and the heat transfer function(OHDP) are deactivated.
OCMI (2) Collector minimum temperature
The minimum collector temperature is the lowest switch-on temperature for triggering the solar
pumpR1(2), If the collector temperature falls below the minimum temperature,
is
displayed and code CMIN displays.
OCFR(2)Collector antifreeze function When the collector temperature falls below the switch-on temperature CFRO(2)of antifreeze function, this function activates the solar pump to circuit system between collector and tank.

is displayed on the screen. are blinks on the screen, and code CFRO
Note: Since this function uses the limited heat energy stored in the tank, the antifreeze function should be used only in regions with few days of temperatures around the freezing point.
OTCO (2)Tube collector function This function is used for improving the switch-on behavior in systems with non-ideal sensor positions (e. g. with some tube collectors).
This function operates within a pre-set time – section. It activates the collector circuit pumpR1(2) intermittently to compensate for the delayed temperature measurement caused by poor sensor position.
If the runtime is set to more than 10s, the pump will run at 100% speed during the first10s, and pump will run at the minimum speed during the remaining runtime.
If the collector sensor is defective, this function will be switched off.
In 2-collectorfields systems, the tube collector function is available for each individual collector field.
In 2-collector fields systems, the tube collector function will affect the inactive collector field only. The solar pump of the active collector field will remain switched on until the switch-off conditions are fulfilled.

12LLOGI Tank priority logic Priority logic Priority logic is designed for
systems with 2-tanks or systems with tank loading in layers; it determines how
the heat is divided between the tanks. Several different priority logic types
can be selected: Tanks loading in sequence (1 and 2) Successive loading (Su 1
and Su 2) Parallel loading (0) Tanks heated in sequence (1 and 2) If the
priority tank is not loaded because its switch-on condition is not reached,
then the subordinate tank is checked whether its switch-on condition is
reached, if yes, then it is loaded during the circulation runtime (tRUN).
After runtime, heating process stops, then break time timer tLB starts to
ensure collector to receive more solar energy, during the break time,if the
priority tank switch-on condition is still not reached, then the subordinate
tank will be loaded again for the circulation runtime.
As soon as the priority tank meets its switch-on condition, controller
triggers to heat it immediately, if the priority tank’s switch-on condition is
still not reached, controller heats the subordinate tank continuously. If the
priority tank reaches to its preset temperature, and then tank heated sequence
function is stopped.
Page 67 of 113
Downloaded from www.Manualslib.com manuals search engine
Operation manual of solar controller SR658 In systems with 2 tanks or tank
loading in layers, all tanks or zones will be heated to its preset temperature
firstly (base the priority and sequence control logic). Only when all tanks or
zoneshave exceeded its preset temperature, they just can be heated to their
maximum temperature continuously, and it is also heated base the priority and
sequence control logic.
If the tank sequence heating function is activated and system is switched to
heat the priority tank, then parameter “heating break time” can also act as
stabilization time, during which the switch – off temperature difference will
be ignored while the system operation stabilizes.
Successive loading (Su 1 and Su 2) Successive loading means that the priority
tank will be heated to its maximum temperature. After the priority tank
reaches its maximum temperature, then the second tank will just be heated. If
the temperature of the priority tank falls below its pre-set temperature, then
the second tank will no longer be heated, regardless of whether the switch-on
condition of the priority tank or the second tank is met.
If both tanks are heated to their preset temperature, the same process will
occur until the tank reaches its maximum temperature
Parallel loading (0) In systems with 2 pumps, if parallel loading control
logic is selected, 2 tanks will be heated parallelly. In system with 3 – ways
valve, tank which temperature is lower will be heated in advance until its
temperature is 5K higher than another tank, and then the second tank just can
be heated. Two tanks are alternately heated with a 5K temperature difference.
OSTS Tank set option (only available at LLOGI/PRIO 1or 2 mode) If the priority
tank reaches its pre-set temperature, then the subordinate tank will be heated
until to its set temperature. After this, priority tank can be loaded to its
maximum temperature, and then system is switched to load the subordinate tank.
This function is suitable for 2 tanks’ system.
OSE Spread loading function (only available at LLOGI/PRIO1,2,Su1 or Su2mode)
Insystem5, spread loading function will be activated. When the spread
temperature difference DTSE between collector and priority tank is reached,
the second tank will be loaded in parallel unless it is blocked. If the spread

13COOL Cooling function Function description: Different cooling functions for
different devices can be activated: system cooling, tank cooling and external
radiator heat transfer.
OSYC System cooling
The system cooling function is designed to keep the solar system operation for a longer time.
The function overrides the maximum tank temperature to transfer the energy from collector
field to the tank. If the tank temperature is higher than its maximum tank temperature already
and the switch-on temperature difference of this function DTCO is reached, then the solar
pump remains running. Solar loading is continued until either the temperature difference falls
below the switch-off temperature DTCF or the collector emergency temperature OCEM
reaches
If the system cooling function is running, then
icon displays, and
icon blinks on
the screen, code OSYC displays on the screen.
Note:This function will only be available when the collector cooling function, external radiator heat transfer functions are not activated.
OSTC Tank cooling
When the tank cooling function is activated, this function is designed to cool down the tank
during the night and provide possibility for solar loading on the following day. If the maximum
tank temperature SMAX is exceeded, the collector temperature falls below the tank
temperature, and it is below the switch on temperature difference DTCO of this cooling
function, then system will be activated to cool down the tank by releasing the energy through
the collector in night
If the tank cooling function is running, icon
displays, and icon
blinks on the
screen, code OSTC displays.
Note: if tank temperature reaches to 95 oC, all cooling functions will be locked. Hysteresis switch on temperature difference is 5K.

1. According to the selected system, several auxiliary functions are
allocated with a same relay output, at this case, then only one of the several
auxiliary functions can be activated, the other functions will be deactivated
automatically, its function displays “NONE”.
2. According the different selected system, see paragraph 4.1, the function
will assign to different output ports)
Under strong solar irradiation, external radiator heat transfer function is
designed to release the excess thermal energy generated by solar system
through an external heat exchanger (e. g. fan coil), aim is to keep the
temperature of collector or tank within its operation range. For this
function, an extra output RX should be added. (system is different, the output
relay of circuit pump RX may be different also, detailed allocation see
diagram showed in system description)
External radiator heat transfer function can either control an additional pump
or valve (OTPUM ON = pump logic, OTPUM OFF = valve logic).
Heat transfer by pump logic: If the collector temperature reaches the switch-
on temperature(OTST), the heat transfer pump(RX) on. if the collector
temperature falls 5 K below heat transfer temperature(OTST),the heat transfer
pump(RX) off. Heat transfer by valve logic: If the collector temperature
reaches the switch-on temperature(OTST), the heat transfer valve(RX) and
circuit pump(R1) on. if the collector temperature falls 5 K below heat
transfer temperature(OTST),the heat transfer valve(RX) and circuit pump(R1)
off.
Below is the example of this application for reference.

Note 1.According the different selected system, several auxiliary functions
may be assigned to a same output, then only one auxiliary function can be
triggered, others will be deactivated automatically, and its function displays
“NONE”. 2.According the different selected system, this function will be
assigned to the different object sensors and output ports
The solid fuel boiler function is designed to transfer heat from a solid fuel
boiler to a tank, for this function, any sensor input and output relay are
needed.
The relay is energized when all switch-on conditions are met: The temperature
difference between the sensors of solid fuel boiler and heated tank exceeds
the switch-on temperature difference.

Operation manual of solar controller SR658 The temperature at the solid fuel
boiler sensor exceeds its minimum temperature (MINSFO) The temperature at the
heated tank is lower than its maximum temperature (MXSFS)
When the preset temperature difference is exceeded, pump speed control starts.
For every increase or decrease by the rise value, the pump speed will be
adjusted by 10 %. The switch-on hysteresis is -5 K.
Notesensor on the upper part of the heated tank is the priority sensor, if on
the upper part no sensor is installed or sensor is damaged, then controller
will take the signal from bottom sensor automatically. Menu Structure

Notein a system, if several auxiliary functions are all allocated to output R2
(see system description), then only one auxiliary function can be activated,
others function will be deactivated automatically, and these functions
displays “NONE” Depend on the selected system; following functions may be
triggered.
TIMER (Timer function) (According the different selected system, this function
will be assigned to the different output ports)
Timer function can trigger controller’s output port at the pre-set time;
therefore, an available output is needed.
When
display on the screen, it’s mean that TIMER function is activate. When the icon
flashes, it means that the function is running.
AH Thermostat function
(According the different selected system, this function will be assigned to
the different object sensor and output port)
The thermostat function is independent from the solar operation system, it can e. g.be used for
using surplus energy or for back-up heating. (Every day 3 heating time – sections can be set)
Note:
1. AH O <AH F: Thermostat function used for back-up heating
2. AH O >AH F: Thermostat function used for releasing surplus energy from tank.
3. Icon AH displays on the screen, it means thermostat function for back-up heating is
activated. AH flashes, it indicates this function is running.
4. Icon
displays on the screen, it means thermostat function for heating release
is activated, icon flashes, it means that function is running.
