Precision-platin sensors type PT1000 (FKP and FRP) areused for DeltaSolDeltaSolDeltaSolDeltaSolDeltaSol® B.

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.

3.2.6 ∆∆∆∆∆T-controller (DODODODODO, DFDFDFDFDF)

The controller controls the temperatures measured by thetwo sensors S1 and S2 and compares the resultingtemperature difference with the preadjusted switch-on-temperature difference ∆T

ON (DO). The controller switches

ON, when the measured temperature difference ∆T is higherthan or identical to the preadjusted set value in channel DO.In the display is shown and the operating control lampflashes green. When the adjusted switch-off-temperature-difference ∆TOFF (DF) is underrun, the controller switches-OFF. By RESOL, the switch-on temperature difference is setto 6 K and the switch-off temperature difference is set to4 K.

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

3.2.7 Maximum store temperature (SXSXSXSXSX)If the adjusted maximum temperature is exceeded, a furt-her loading of the store is stopped so that a damagingoverheating can be avoided. The maximum store temperatureis activated by factory setting (FN =3). If the maximum storetemperature is exceeded in the display is shown and (flashing), the operating control lamp flashes red. In order torealize a pure maximum temperature limitation and todeactivate the recooling- and/or collector cooling function,FN = 1 must be adjusted.

3.2.1 Indication channel TCThe indication channel TC indicates the current sensortemperature of the heat source (e.g. collector sensor) in °C.

3.2.2 Indication channel TSThe indication channel TS indicates the current sensortemperature of the heat sink (e.g. store sensor) in °C.

3.2.3 Indication channel TT / T3The indication channel TT/T3 indicates the current sensortemperature for the thermostat function (only PG 53.02 /54.02) or of the additional sensor (PG 51.02 / 52.02, withoutinfluence oon regulation) in °C.

3.2.5 Indication channel HOThe indication channel HO (only PG 51.02 / 53.02) indicatesthe solar operating hours of the solar pump resp. theoperating hours of the consumer connected to the relayoutput R1. The summed-up operating time is saved in an 6-hour-cycle so that the maximum deviation in case of a powerfailure is 6 hours at the most. This display value can not beresetted.

3.2.4 Indication channel PCThe indication channel PC (only PG 52.02 / 54.02) indicatesthe current relative rotational speed of the solar pump resp.the rotational speed of the consumer connected to the relayoutput R1.

3.2.8 Limit collector temperature (CLCLCLCLCL)Extremely high collector temperatures are normallyintercepted by a properly dimensioned membrane-expansionball. If the preadjusted collector limit temperature(CL) is exceeded, the solar pump (R1) is switched-off 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.

3.2.9 Maximum collector temperature (CXCXCXCXCX)If the collector temperature exceeds the adjusted maximumcollector temperature (CX) in standstill of the solar circuit(maximum store temperature is reached), the solar pump(R1) switches-on and cools the collectors by heat transfervia lines and the store (collector cooling function). The storetemperature might increase, but only up to 90 °C (safetyshutdown of the store). This function guarantees a longeroperating time for very hot summer days and ensures a ther-mal relief for the collectors and the heating medium. Themaximum collector temperature is set to 120 °C by RESOL,but it can be changed within the adjustment range of100 °C ... 190 °C. In the display is shown , and ifthe maximum collector temperature is exceeded, theoperating control lamp flashes green.

3.2.11Recooling function

Recooling (FN 2FN 2FN 2FN 2FN 2):If the adjusted maximum store temperature (S XS XS XS XS X) isexceeded, the solar pump remains activated in order to avoidan overheating of the collector. The store temperature mayincease - but only up to 90 °C (store safety shutdown).The solar systems remains running in the evening until thestore is cooled down to the adjusted maximum storetemperature (S XS XS XS XS X) by the collector or lines.

The minimum collector temperature is a minimum switchingtemperature, which must be exceeded so that the solarpump (R1) is switched-on. The minimum temperature shallavoid a steady starting-up of the solar pump (or solid fuelboiler charging pumps) for low collector temperatures.Theminimum temperature is set to 10 °C by RESOL (=deactivated). In the display is shown and if theminimum collector temperature is exceeded, the operatingcontrol lamp flashes green. This function analogly is alsousable as minimum temperature limitation for solid fuelboilers, 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.

Collector cooling function (FN 3FN 3FN 3FN 3FN 3):If the adjusted maximum store temperature is reached, thesolar system switches-off. If the collector temperature nowraises up to the adjusted maximum collector temperature(CXCXCXCXCX), the solar pump remains activated until this limittemperature value is again underrun. The store temperaturemay increase - but only up to 90 °C (store safety shutdown).If the maximum store temperature (SX) is exceeded by thestoretemperature and the collector temperature is al least5K below the store temperature, the solar system remainsrunning until the store is cooled down to the adjustedmaximum store temperature (SX) by the collector and thepipes.

3.2.13 Mininum pump speed The indication channel PN makes it possible to preadjusta minimum value for the relative rotational speed of thecomponent connected to R1. 100% have to be adjusted(rotational speed deactivated) for components which arenot RPM-regulated.

The controller (1) measures the temperaturedifference between collector sensor S1 and store S2. Assoon as this difference is higher or identical to the adjustedvalue (DO), the pump (3) is started and the store is loaded

up. If the switch-off temperature difference (DF) is underrunby this difference, the pump is stopped.

The 3rd temperature sensor S3 is an additional sensor formeasuring purpose, e.g. for measuring the upper storetemperature.

6.2 Solar system with 1 collector, 1 store and afterheating (only PG 53.02/54.02):

Solar irradiation transfers heat which is made utilizable bythe heat exchanger of the store (4) via collector (2) to thesystem (2). The controller (1) measures the temperaturedifference between collector sensor S1 and store sensor S2.As soon as this difference is higher or identical to theadjusted value (DO), the pump (3) is started and the storeis loaded up. If the switch-off temperature difference (DF)is underrun by this difference, the pump is stopped.

The 3rd temperature sensor S3 can be used for thermostatfunction. The thermostat switch-on temperature (TO) andthe switch-off temperature (TF) must be adjusted in the

adjustment channels. Depending on your adjustment, thethermostat function works in after-heating or coolingopertion.

Necessary adjustments for store after-heating:

TO = 40 °CTF = 45 °C

The adjustmens can be adapted to the individual systemconditions.

value ∆T, the reverse temperature is increased by thewarmth of the buffer store when connecting the 3-way-valve (3)(heating support) .

The controller (1) compares the temperatures measuredby sensor S1 in the boiler or chimney boiler (2) with thetemperature measured by sensor S2 in the store (3). If themeasured temperature difference is higher or identical tothe adjusted value DO (switch-on temperature difference),the pump (4) is activated, if the adjusted minimumtemperature (CN, adjustment range 10,1 ...90 °C) issimultaneously reached or exceeded. If the switch-off

temperature difference DF or the minimum temperature isunderrun, the pump switches-off.

Necessary adjustment for minimum temperature limitation(to avoid flue gas condensation):

CN = 60 °C (recommended)

6.5 After-heating of the boiler by buffer store:

The controller(1) measures the temperature differencebetween buffer store sensorS1 and store sensor S2. As soonas the difference is higher or identical to the adjusted value(DO), the pump (3) is activated and the store is loaded up.If the switch-off difference (DF) is underrun by the measureddifference, the pump is again deactivated.


6.6 Swimming pool solar system:

The controller (1) measures the temperature differencebetween collector sensor S1 and swimming pool reversesensor S2. As soon as the difference is higher or identicalto the adjusted value (DO), the pump (3) is activated so thatthe water in the pool is heated up. If the switch-offdifference (DF) is underrun by the measured difference, thepump is again deactivated.

6.7 Thermostat after-heating function (only PG 53.02):

The third temperature sensor S3 can be used for thethermostat function. The thermostat switch-ontemperature TO and the thermostat switch-off temperatureTF must be adjusted in the adjustment channels. Dependingon the adjustment, the thermostat function works in after-heating or cooling operation.

to = 40 °C, tf = 40 °C

• to = tfthe thermostat function is deactivated, that meansthat relay output R2 is activated if the maximum storetemperature is exceeded

• To < Tfthe thermostat function is used as after-heating

• To > Tfthe thermostat function is used as surplus energy
