Thermostat-Function (Function block 1... 5) Arrangement/Options/Thermo This option switches on if the selected switch-on tempeature is reached and switches-off if the selected switch-off temperature is exeeded. The reference sensor is selectable in the expert menu. Store maximum limitation Solar/Adj. values/tstmax Adjustment range 4... 95 C Factory setting 60 C Hysteresis 2 K (factory setting) If the adjusted maximum temperature Tspmax is exeeded, the loading of the store is stopped. If the store cools down by more than 2 K, the store loading starts again. The Hysteresis can be adjusted in the menu Solar/Expert Security switch-off of the store Fixed value 95 C Hysteresis 2 K If the cooling option is activated (e.g. collector cooling), the store is charged beyond the adjusted maximum temperature. In order to avoid too high temperature in the store, the security switch-off of the store is additionally provided, which also blocks the store for cooling option. If a store temperatureb of 95 C is reached, the security switch-off is activated. Store blocked A store is blocked if either the belonging sensor is defect or the security switch-off temperature is reached. Collector security switch-off Solar/Adj. values/sec Adjustment range 110... 200 C Factory setting 130 C Hysteresis 10 K In case of high collector temperatures (dependant on e.g. system pressure or content of frost protection), the heat transport medium evaporates. That means, that a solar charge is longer possible. If the adjusted temperature threshold sec is exceeded,the charge at each collector is suspended. Note: if the option collector cooling is activated, the security switch-off temperature can t be adjusted lower than the maximum collector temperature (max). Collector blocked A collector is considered to be blocked if either the sensor is defect or the securtiy switch-off temperature is reached. Collector minimum limitation Solar/Expert/min Adjustment range -25... 90 C Factory setting 10 C Hysteresis 2 K A collector for solar operation is considered to be blocked if the adjusted minimum temperature is t exceeded or the condition collector blocked is achieved. 19
Store charging Solar/Adj. values/ Ton Adjustment range 1,5... 20,0 K Factory setting 5,0 K Solar/Adj. values/ Toff Adjustment range 1,0... 19,5 K Factory setting 3,0 K If the adjusted switch-on difference Ton between collector and store is exceeded, the store is charged. If this difference falls under the adjusted switch-off difference Taus charging is stopped. The store charge is also suspended if the relevant store or collector is blocked (collector solar blocked) or if the store is at maximum limitation. Cooling function Solar/Options/Col. cooling The cooling function can be used in 1-store systems. If the store is at maximum limitation, the surplus energy in the collector can be derived. The pump output (provided that it is activated) is controlled with relative maximum pump speed. Operation mode (switching conditions) If the store is at maximum limitation and the switch-on temperature difference Ton between collector and store is reached, the solar circuit (primary) and the cooling relay are operated. If the switch-off temperature difference Taus is underrun in this period, the solar circuit and the cooling relay are switched-off. 2-collector systems Only the collector circuit, which complies with the above described switch-on criteria, is operated in these systems. Frost protection Solar/Options/Frost prot. 2-collector systems As soon as 4 C are underrun at the collector, the frost protection function operates the loading circuit between collector and 1st store in order to protect the medium in the loading circuit against freezing or coagulation. If the collector temperature exceeds 5 C, this function is switched-off. If the 1st store is blocked in the system, this function is suspended. The pump output is controlled with relative maximum pump speed Only that circuit is operated, which complies with the above mentioned switch-on conditions. Chimney sweeper activate Expert/Chimney 20 This function is used for activating a fixed relay condition ifit is required. Because of that e.g. in case of flue gas measurement made by the chimney sweeper, the relays required for activation of the boiler can be switched-on. The required relay status is adjusted in the chimney sweeper menu.
St2on... Sp4off By means of this function, the respective store can be removed from the solar regulation, that means that it is longer considered for solar charge. The temperature of the store is furthermore indicated but a sensor defect is longer signalised. Collector cooling function Solar/Adj. values/max Adjustment range 80... 160 C Factory setting 110 C Hysteresis 5 K The collector cooling function starts if the adjusted maximum collector temperature is reached. If this temperature is underrun by 5 K, this function is switched off. The collector is cooled by the heat dissipation to the next free store, that means to a store which is t blocked. The numerically last store is t considered (swimming pool protection). The pump output is controlled with relative maximum pump speed Note: it is t possible to adjust the maximum collector temperature (max) higher than the collector security switch-off temperature. 2-collector systems 2 separate collector circuits (2 pumps) Only that collector circuit, which needs to be cooled, is operated. If one store is charged right w by ather collector, this charge is continued. Recooling Solar/Options/Recooling shared collector circuit (1 pump) The pump speed of the pump acts upon collector cooling. A parallely operating store charge by the 2nd collector is subordinated. This function is used for keeping the system temperatures and consequently the thermal load as low as possible. If all stores of a system have exceeded the maximum temperature, the loading circuit for 1st store is again operated in order to reduce the surplus energy from tubes and collector. This circulation is again switched-off if the maximum store temperature is underrun by 2 K. 2-collector systems Combination with collector cooling function: 2-collector systems Both collector circuits are activated in a 2-collector system. If the option collector cooling is activated in addition to the recooling function, the response action of the recooling function changes. The objective is w to dissipate the energy supplied by the collector cooling. If the temperature at the collector decreases by 5 K below that of the store, the recooling function is activated and the loading circuit is again operated (for cooling of the store). If the difference between collector and store decreases below 3 K during that cooling period, the function is switched-off. In a 2-collector system, the collectors are separately operated due to the above-desribed switch-on conditions. 21
Arrangement/Options/ The -function controls if the temperature at the given sensor (Sen-) exceeds a temperature of 60 C. If 60 C are t reached up to start time, this function is activated in order to activate e.g. an after-heating. The function is switched-off when 60 C are reached at the relevant sensor or at midnight (reset). If the relevant sensor does t work, this function is suspended. CS-Bypass Solar/Adj. values/cs-byp. Adjustment range 100... 500 W/m2 Factory setting 200 W/m2 If the irradiation exceeds the adjusted value CS-bypass, so that the collector circuit is operated. It is switched-off if the irradiation falls 2 minutes below the value CS-bypass. The collector circuit is operated with minimum pump speed. 2-collector systems If a loading of the stores is effected in these systems, the function is switched-off. Tube collector special function Solar/Options/Tube col. Solar/Expert/Tube run Solar/Expert/Tube-init Solar/Expert/Tube-Final This function considers the unfavourable sensor positioning of tube collectors. This function operates within a given time slot ( tube-start and tube-end ). It activates the collector circuit every 30 minutes at collector standstill (adjustable by parameter tube collector ) for 30 seconds (adjustable by the parameter tube-run ) in order to compensate the delayed temperature measurement. If the collector sensor is faulty or the collector is blocked, this function is suspended or switched-off. The collector circuit is operated with minimum pump speed control. 2-collector systems 2 separate collector circuits (2 pumps) Both collectors are independantly operated by this function. If store charge is effected by one collector, the other one is nevertheless operated according to the adjusted standstill time. shared collector circuit (1 pump) If store charge is effected by one collector, the other one is nevertheless operated according to the adjusted standstill time. That means, that minimum pump speed is adjusted and a possible pump speed is igred by the controller. 22
Bypass Solar/Options/Bypass Valve version In order to avoid energy emission from the store when starting the store charge, this function provides that the cold medium from the lead is passed the store via bypass. If the lead is warm eugh, the store charge can start. The bypass relay is operated if the relevant sensor is 2,5 K higher than store charge temperature and the irradiation condition for store charge (see store charge) is achieved. This function is switched-off if the temperature difference is lower than 1,5 K. Pump version A bypass pump is advanced to the collector pump in this version. The bypass pump is at first operated in case of a possible store charge. If the above-mentioned switch-on condition is achieved, the bypass pump is switched-off and the collector circuit pump is activated. This version is only available for 1-collector systems. External heat exchanger Solar/Options/Ext. heat ex. This function is used for reasonable linking of charge circuits, which are separated by an external heat exchanger (different heat transfer media). The heat exchanger relay is operated if the relevant sensor shows a temperature which is by the adjusted value heat exchanger Ton higher than the store temperature and the switch-on conditions for store charge (see store charge ) are achieved The relay is switched-off if this temperature difference falls below the adjusted switch-off difference HE- Toff. In contrast to the bypass function, a differential regulation between T-HE and Tst can be realised by means of the heat exchanger relay. In systems in which stores are equipped with loading pumps, the relay external heat exchanger controls the primary circuit pump. Parallel relay If the solar circuit pump(s) is/are switched-on, this relay is parallely activated. In 2-collector systems which are working with 2 pumps it is activated if one of the 2 pumps are switched-on. 23
Store loading Arrangement/Options/Store load. In order to realize the after-heating of a store within a certain store volume (zone), this function needs 2 sensors to control switch-on and switch-off level. As reference parameters the switch-on and -off temperatures Th7on and Th7off are used. The refernce sensors can be activated by Sen-Th7 and Sen Th8. If the measured temperatures at both reference sensors fall below the adjusted switching treshold Th7on, one relay is switched-on. It is switched-off if the temperature at bothsensors is higher than Th7off. If one of the two sensors is defective, the store loading is suspended or broken off. In addition to that, this option can temporally be blocked by means of the daily timer 2. After-heating-suppression This function is activated if a previously selected solar store is charged. Solar loading means that this store loading is only made for energymeasurement and t for cooling purpose or something else. Message relay (Error report) This function is activated if a fault is realized by the controller. In that case the message relay is activated (e.g. for signal lamps) These errors are: Sensor defect Real-time-clock defect Ram (EEPROM) defect Please te that a message made by the plausibility control does t activate a relay System warning Non-ret. valve This message is shown if the collector temperature between 11 p.m. and 5.00 a.m. is higher than 40 C or a store is charged. In order to avoid release of this message due to short-term disturbences, the above-mentioned release condition must be given for 1 minute. System warning T too high 24 This message is shown if a solar loading is effected for a period of 20 minutes with a difference higher than 50 K.

If the outside temperature exeeds the adjusted value the heating circuit switches off. Store prio. This function switches-off the heating circuit during afterheating. The option service water has to be activated and the boiler loading has to be realised by the controller DeltaSol E. Timer Timer/Mode Example: The night correctionruns Tuesday from 22:00 to 6:00 and from 15:00 to 18:00, for it set t1-on to tue,22:00, t1-off to tue,6:00 and t2-on to tue,15:00 and t2-off to tue,18:00. For the case that all time frames are set to 00:00 the night correction is deactivated and the heating circuit runs 7days, 24h in the daily operation (factory setting). The timer sets either the day correction or the night correction for the change of the set flow temperature is used. 21 different time frames can be set for the night correction. If one of the time frames is set active the night correction is used. For the case that ne of the them is in use the day correction brings more the flow temperature and set flow temperature in line. A time frame is activated when the current time is located between the switch-on and -off point.
