1.1 Mounting

The unit must only be located internally. It is not suitable forinstallation in hazardous locations and should not be sitednear to any electromagnetic field. The controller mustadditionally be equipped with an all-polar gap of at least 3mm or with a gap according to the valid installatonregulations, e.g. LS-switches or fuses. Please pay attentionto a separate laying of the cable lines and installation of acpower supply.

1. Unscrew the cross-recessed screw of the cover andremove it from the housing.

2. Mark the upper fastening point on the underground andpremount the enclosed dowel and screw.

3. Hang up the housing at the upper fastening point and markthe lower fastening point on the underground (hole pitch130 mm), afterwards put the lower dowel.

4. Fasten the housing at the underground.

1. Installation Warning!Switch-off power supply beforeopening the housing.

1.2 Electrical wiring The power supply to the controller must only be made byan external power supply switch (last step of installation!)and the line voltage must be 210 ... 250 Volt (50...60 Hz). Fle-xible lines are to be fixed at the housing by enclosed strainrelief supports and screws.The controller is equipped with 2 standard relays, to whichthe consumers e.g. pumps, valves etc. can be connected:

• Relay 118 = conductor R117 = neutral conductor N13 = ground clamp

• Relay 216 = conductor R215 = neutral conductor N14 = ground clamp

The temperature sensors (S1 up to S4) will be connectedto the following terminals independently of the polarity:

1 / 2 = Sensor 1 (e.g. Sensor collector 1)3 / 4 = Sensor 2 (e.g. Sensor store 1)5 / 6 = Sensor 3 (e.g. Sensor collector 2)7 / 8 = Sensor 4 (e.g. Sensor store 2)

The power supply is effected to the clamps:

Precision-platin sensors type PT1000 (FKP and FRP) areused for DDDDDeltaSeltaSeltaSeltaSeltaSol ol ol ol ol B Pro.

The arrangement of the sensors is of great importance tothe total efficiency of the regulator. The collectortemperature should be measured in the upper part of thecollector. In stores with integral heat exchanger, the sensormust be directly mounted in the upper part of the heatexchanger. When using external heat exchangers, the sensormust be fixed at the bottom of the store. For individualoperation systems, our product range contains 3 differenttypes of sensors (sensors for installation in existingimmersion sleeves, flatscrew sensors or cylindrical clip-onsensors). The sensor types FK and FR have the sameelectrical features and are available in the same models, Theyonly differ in the connecting cable:

2. Sensor types

Immersion sensors: in different lengths (immersiondepth) availableFK...60: 60 mm immersion depth, immersion sleeves ofchromium-plated brassFK...150: 150 mm immersion depth, immersion sleeve ofchromium-plated copperImportant: The sensors must be completely pushed intothe sleeve and the nut must be slightly tightenend.

Cylindrical clip-on sensors: for any pipe diameter; cpl.with fastening collar; FK...21 or FR...21Ensure good thermal contact of the sensor with the pipework by cleaning the contact area and by applying heatconduction paste between sensor and pipe. In order toprotect the sensor cable against outside temperatureinfluences, it is recommended to insulate the pipe.

Flatscrew sensors: for installation on flat surfacesFK...9 or FR...9Ensure good thermal contact. Use conduction paste andinsulate the sensors against outside temperature influences.Indication:In order to avoid overvoltage damage at the collector (e.g.by lightening), it is highly recommendend to use theovervoltage protection RESOL SP1.

FK... : collector sensorFR... : reference sensor (store sensor)

FK: 1,5 m weather- and temperature resistant silicone cablefor temperatures between -50 °C ... +180 °C, mostly usedfor collectors.

FR: 2,5 m PVC cable for tempertures between-5 °C ... +80 °C, mostly used for stores.

Make sure that all electrical works are carried out accordingto the relevant local and IEE-regulations. The sensor cablescarry low voltages and they must not run together in a cableconduit with cables carrying higher voltages than 50 Volts.When using longer cables or cable conduits, please usescreened cables. The sensor cables can be lengthened up to100 m, but the cross section must be 1,5 mm² (or 0,75 mm²up to a cable length of 50m); screened cables should be usedpreferably. The sensors must not be in direct contact withwater, please always use immersion sleeves.

3.2.4 ∆∆∆∆∆T-regulation (DO 1/DO 2, DF 1/DF 2) The controller controls the temperatures measured by foursensors S1, S2, S3 and S4 and compares the resultingtemperature difference with the preadjusted switch-on-temperature difference ∆Ton (DO). The controller switchesON, if the measured temperature difference DT is higherthan or identical to the preadjusted set value in channel DO.In the display is shown and the operating control lampflashes green. If the adjusted switch-off-temperature-difference ∆Toff (DF) is underrun, the controller switches-OFF. The factory setting for switch-on temperaturedifference is 6 K and the switch-off temperature differenceis set to 4 K.

Please note: Switch-on temperature difference DO mustbe at least 1 K higher than the switch-off temperaturedifference DF.

3.2.6 Limit collector temperature (CL 1/CL 2) If the adjusted collector temperature limit (CL1/2) isexceeded the solar pump (R1/R2) is deactivated in orderto avoid a damaging overheating of the solar components(collector safety shutdown). The limit temperature is set to140 °C by RESOL but it can be changed within theadjustment range of 110 ... 200 °C. In the display is shown

and if the maximum collector temperature isexceeded, the operating control lamp flashes red.

CL:Collector limitingtemperatureAdjustable values 110 ... 200 °C,Factory setting 140 °C

3.2.7 Maximum collector temperature (CX 1/CX2)

If the collector temperature exceeds the adjusted maximumcollector temperature (CX1/2) in standstill of the solarcircuit (maximum store temperature is reached), the solarpump (R1/R2) switches-on and cools the collectors by heattransfer via lines and the store (collector cooling function).The store temperature might increase, but only up to 95 °C(safety shutdown of the store). This function guarantees alonger operating time for very hot summer days and ensuresa thermal relief for the collectors and the heating medium.The maximum collector temperature is set to 120 °C byRESOL, but it can be changed within the adjustment rangeof 100 °C ... 190 °C. In the display is shown , and if the maximum collector temperature is exceeded, theoperating control lamp flashes green.

CX:Maximum collector temperatureadjustable values 100... 190 °CFacory setting 120 °C

The minimum collector temperature is a minimum switchingtemperature, which must be exceeded so that the solarpump (R1/R2) is switched-on. The minimum temperatureshall avoid a steady starting-up of the solar pump (or solidfuel boiler charging pumps) for low collectortemperatures.The minimum temperature is set to 10 °C byRESOL (= deactivated). In the display is shown and if the minimum collector temperature is exceeded, theoperating control lamp flashes green. This function analoglyis also usable as minimum temperature limitation for solidfuel boilers, recommended adjustment value: 60 °C.

Please note:The minimum collector temperature is used for adjustmentof the frost protection function between -10,0 ... 9,9 °C forminimum temperature function between 10,1 ... 90 °C.

For deactivating the system cooling adjust the values ofOC1 and OC2 to 0.

The controller checks the stores regarding loading facilities(switch-on difference). If the priority store cannot be loaded,the lower-ranking store is checked. If the lower-ranking torecan be charged, this is effected by the so-called „oscillatingcharge time (TR)“. After termination of the oscillating chargetime (TR), the loading is stopped. The controller controlsthe increase in collector temperature. If it increases by thecollector rising temperature (∆T-col 2K, fixed softwarevalue), the expired break time is again reset to zero and theoscillating break time starts again. If the switch-on conditionof the priority store is not reached, the loading of the lower-ranking store is continued. If the priority switch has reachedits maximum temperature, the oscillating charge is noteffected.

Oscillating break time / oscillating charge time /collector rising temperature:

3.2.9 System cooling (OC 1/OC 2) If the adjusted maximum store temperature is exceeded, thesolar system switches off. If the collector temperature againincreases and the adjusted maximum collector temperature(CX1/2) is reached, the solar pump is running until the limittemperature is again underrun. In doing so, the storetemperature can increase (subordinated active store safetyshutdown), but only up to 95°C (safety shutdown of thestore). If the store temperature is higher than the maximumstore temperature (SX1/2) and the collector temperatureis at least 5K lower than the store temperature, the solarsystem is working until the store is recooled by thecollector and the pipes to the adjusted maximun storetemperature (Sx1/2).

The controller compares both temperature differencesbetween collector sensor S1 and store sensor S2 as well asbetween solid hot fuel boiler S3 and store sensor S4. Thewarmth of the collector is given to the store, if the switch-on temperature difference (DO/1) is exceeded. The pumpR1 remains activated until the switch-off temperature

difference (DF/1) is underrun. The solid hot fuel boiler isactivated by control of the pump R2, if the 2nd switch-ontemperature difference (DO/2) as well as the additionnallypreadjusted minimum temperature (CN/2) are exceeded (inorder to avoid flue gas condensation). The store is only loa-ded up until the adjusted maximum store temperature (SX1/2).

The controller measures the temperature difference betweencollector sensor S1 and store sensor S2. As soon as thisdifference is higher or identical to the adjusted value forswitch-on temperature difference (DO/1), the pump R1 isactivated and the store is loaded until the switch-offtemperature (DF/1) or the maximum store temperature (SX/1)

is reached. At the same time a heat exchange regulation iseffected inpendently on the solar circuit. If the switch-ontemperature difference (DO/2) between sensor S3 and S4is exceeded, the pump R2 is activated and the store is loa-ded (heat exchange between solar- and existing store).
