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 activated. If this sign blinks,it indicates DHW circuit pump is running. Note: Page 47 of 113 Downloaded from www.Manualslib.com manuals search engine Operation manual of solar controller SR658 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.

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 Page 54 of 113 Downloaded from www.Manualslib.com manuals search engine Operation manual of solar controller SR658 loaded to avoid damage caused by overheating.

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.

If collector antifreeze function is activated, If collector antifreeze function is running, displays. 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.

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 temperature Page 68 of 113 Downloaded from www.Manualslib.com manuals search engine Operation manual of solar controller SR658 difference falls 2K below DTSE temperature, the pump will be switched off.

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. OHDP external radiator heat transfer Note Page 71 of 113 Downloaded from www.Manualslib.com manuals search engine Operation manual of solar controller SR658 1.

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.
