1.1 Mounting

The unit must only be located internally. It is not suitable for installation in hazardous locations and should not be sited near to any electromagnetic field. The controller must additionally be equipped with an all-polar gap of at least 3 mm or with a gap according to the valid installaton regulations, e.g. LS-switches or fuses. Please pay attention to a separate laying of the cable lines and installation of ac power supply.

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

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

3. Hang up the housing at the upper fastening point and mark the lower fastening point on the underground (hole pitch 130 mm), afterwards put the lower dowel.

4. Fasten the housing at the underground.

1. Installation

Warning! Switch-off power supply before opening the housing.

1.2 Electrical wiring

The power supply to the controller must only be made by an external power supply switch (last step of installation!) and the line voltage must be 210 ... 250 Volt (50...60 Hz). Flexible lines are to be fixed at the housing by enclosed strain relief supports and screws.

The controller is equipped with 2 standard relays, to which the consumers e.g. pumps, valves etc. can be connected:

• Relay 1

18 = conductor R1 17 = neutral conductor N 13 = ground clamp

• Relay 2

16 = conductor R2 15 = neutral conductor N 14 = ground clamp

The temperature sensors (S1 up to S4) will be connected to 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:

The arrangement of the sensors is of great importance to the total efficiency of the regulator. The collector temperature should be measured in the upper part of the collector. In stores with integral heat exchanger, the sensor must be directly mounted in the upper part of the heat exchanger. When using external heat exchangers, the sensor must be fixed at the bottom of the store. For individual operation systems, our product range contains 3 different types of sensors (sensors for installation in existing immersion sleeves, flatscrew sensors or cylindrical clip-on sensors). The sensor types FK and FR have the same electrical features and are available in the same models, They only differ in the connecting cable:

2. Sensor types

Immersion sensors: in different lengths (immersion

depth) available FK...60: 60 mm immersion depth, immersion sleeves of chromium-plated brass FK...150: 150 mm immersion depth, immersion sleeve of chromium-plated copper Important: The sensors must be completely pushed into the sleeve and the nut must be slightly tightenend.

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

Flatscrew sensors: for installation on flat surfaces FK...9 or FR...9

Ensure good thermal contact. Use conduction paste and insulate 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 the overvoltage protection RESOL SP1.

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

FK: 1,5 m weather- and temperature resistant silicone cable for temperatures between -50 °C ... +180 °C, mostly used for 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 according to the relevant local and IEE-regulations. The sensor cables carry low voltages and they must not run together in a cable conduit with cables carrying higher voltages than 50 Volts. When using longer cables or cable conduits, please use screened cables. The sensor cables can be lengthened up to 100 m, but the cross section must be 1,5 mm² (or 0,75 mm² up to a cable length of 50m); screened cables should be used preferably. The sensors must not be in direct contact with water, please always use immersion sleeves.

3.2.1 Indication channels S1-S4

The indication channels S1-S4 indicate the current temperatures of the sensors S1-S4 in °C. If the thermostat function is activated (FN=4), the channel TT (thermostat temperature) is indicated.

3.2.2 Indication channels H1 and H2

The indication channels H1 and H2 (if FN1 or FN3 are activated) indicate the solar operating hours of the solar pump or the solar operating hours of the consumer connected to the relays R1 and R2. The operating hours sum is stored every 6 hours, so in case of a power blackout the maximum difference would be 6 hours. This indication value can not be reset.

∆∆

∆T-regulation (DO 1/DO 2, DF 1/DF 2) The controller controls the temperatures measured by four

sensors S1, S2, S3 and S4 and compares the resulting temperature difference with the preadjusted switch-ontemperature difference ∆Ton (DO). The controller switches ON, if the measured temperature difference DT is higher than or identical to the preadjusted set value in channel DO. In the display is shown

and the operating control lamp flashes green. If the adjusted switch-off-temperaturedifference ∆Toff (DF) is underrun, the controller switchesOFF. The factory setting for switch-on temperature difference is 6 K and the switch-off temperature difference is set to 4 K.

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

3.2.6 Limit collector temperature (CL 1/CL 2)

If the adjusted collector temperature limit (CL1/2) is exceeded the solar pump (R1/R2) is deactivated in order to avoid a damaging overheating of the solar components (collector safety shutdown). The limit temperature is set to 140 °C by RESOL but it can be changed within the adjustment range of 110 ... 200 °C. In the display is shown

and if the maximum collector temperature is

exceeded, the operating control lamp flashes red.

CL:Collector limiting temperature Adjustable values 110 ... 200 °C, Factory setting 140 °C

3.2.7 Maximum collector temperature (CX 1/CX

If the collector temperature exceeds the adjusted maximum collector temperature (CX1/2) in standstill of the solar circuit (maximum store temperature is reached), the solar pump (R1/R2) switches-on and cools the collectors by heat transfer 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 a longer operating time for very hot summer days and ensures a thermal relief for the collectors and the heating medium. The maximum collector temperature is set to 120 °C by RESOL, but it can be changed within the adjustment range

of 100 °C ... 190 °C. In the display is shown

, and

if the maximum collector temperature is exceeded, the operating control lamp flashes green.

CX:Maximum collector temperature adjustable values 100... 190 °C Facory setting 120 °C

The minimum collector temperature is a minimum switching temperature, which must be exceeded so that the solar pump (R1/R2) is switched-on. The minimum temperature shall avoid a steady starting-up of the solar pump (or solid fuel boiler charging pumps) for low collector temperatures.The minimum temperature is set to 10 °C by

RESOL (= deactivated). In the display is shown

and

if the minimum collector temperature is exceeded, the operating control lamp flashes green. This function analogly is also usable as minimum temperature limitation for solid fuel boilers, recommended adjustment value: 60 °C.

Please note:

The minimum collector temperature is used for adjustment of the frost protection function between -10,0 ... 9,9 °C for

minimum temperature function between 10,1 ... 90 °C.

For deactivating the system cooling adjust the values of OC1 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 tore can be charged, this is effected by the so-called „oscillating charge time (TR)“. After termination of the oscillating charge time (TR), the loading is stopped. The controller controls the increase in collector temperature. If it increases by the collector rising temperature (∆T-col 2K, fixed software value), the expired break time is again reset to zero and the oscillating break time starts again. If the switch-on condition of the priority store is not reached, the loading of the lowerranking store is continued. If the priority switch has reached its maximum temperature, the oscillating charge is not effected.

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, the solar system switches off. If the collector temperature again increases and the adjusted maximum collector temperature (CX1/2) is reached, the solar pump is running until the limit temperature is again underrun. In doing so, the store temperature can increase (subordinated active store safety shutdown), but only up to 95°C (safety shutdown of the store). If the store temperature is higher than the maximum store temperature (SX1/2) and the collector temperature is at least 5K lower than the store temperature, the solar system is working until the store is recooled by the collector and the pipes to the adjusted maximun store temperature (Sx1/2).

B Pro priority logic:

The DeltaSolB Pro priority logic: The above-mentioned options and parameters are only applied for multiple store systems (system FN=2).

If „prioroty 0“ is adjusted, the stores which show a temperature difference to the collector, are loaded in numerical order (store 1 or store 2). In general, at that time only one store is loaded. For „parallel charging“ you need the adjustment FN=5.

If „priority 1 / 2“ is adjusted, a priority charge of the selected store is effected until its switch-on conditions are fulfilled. The lower-ranking store is loaded by the oscillating charge. If the priority store has reached its adjusted maximum store temperature, the lower-ranking store is loaded until its switch-on conditions are reached.

4. Commisioning

Ac power supply must be activated. The controller passes an initialisation phase in which the operating control lamp flashes red and green. After having finished the initialisation, the controller is in automatic operation, which is the most effective one for most of the systems with the indicated factory settings.

If individual conditions require an adaptation of the parameter, please adjust the values accordingly (see 3.2).

5. Tips for fault location:

Please check the following points if the controller

6. Examples

6.1 Solar system with 1 collector and 1 store with heating reverse raising

The controller measures the temperature difference between collector sensor S1 and store sensor S2. As soon as this difference is higher or identical to the adjusted value for switch-on temperature difference (DO/1), the pump (R1) is activated and the store is loaded until the switch-off temperature difference (DF/1) or the maximum store

temperature (SX/1) is reached. Independently from the solar circuit a ∆T-reverse raising is simultaneously effected. If the switch-on temperature difference (DO/2) of the sensors S3 and S4 is exceeded a 3-way valve is activated for heating circuit support by relay output R2.

The controller compares both temperature differences between collector sensor S1 and store sensor S2 as well as between solid hot fuel boiler S3 and store sensor S4. The warmth of the collector is given to the store, if the switchon temperature difference (DO/1) is exceeded. The pump R1 remains activated until the switch-off temperature

difference (DF/1) is underrun. The solid hot fuel boiler is activated by control of the pump R2, if the 2nd switch-on temperature difference (DO/2) as well as the additionnally preadjusted minimum temperature (CN/2) are exceeded (in order to avoid flue gas condensation). The store is only loaded up until the adjusted maximum store temperature (SX1/

2).

The controller measures the temperature difference between collector sensor S1 and store sensor S2. As soon as this difference is higher or identical to the adjusted value for switch-on temperature difference (DO/1), the pump R1 is activated and the store is loaded until the switch-off temperature (DF/1) or the maximum store temperature (SX/1)

is reached. At the same time a heat exchange regulation is effected inpendently on the solar circuit. If the switch-on temperature difference (DO/2) between sensor S3 and S4 is exceeded, the pump R2 is activated and the store is loaded (heat exchange between solar- and existing store).

6.4 Solar system with 1 collector and 1 store with heat exchange to existing store:

Page 18/24

The controller compares the temperature at the temperature sensor S1 with that of S2 and S3. If the measured temperature differences are higher than the adjusted values for switch-on temperature differences (DO/1) or (DO/2), pump R1 is operated and loaded up by the valve R2 until the

adjusted maximum temperature (SX/1/2) is reached. Priority must be given to one of the two stores, as no parallel loading is possible.

The controller compares the temperature at the temperature sensor S1 with that of S2 and S3. If the measured temperature differences are higher than the adjusted values for switch-on temperature differences (DO/1) or (DO/2), in consideration of the store priority PR the pump R1 or R2 is operated and loaded up until the adjusted maximum

temperature (SX/1/2) is reached. Priority must be given to one of the two stores, as no parallel loading is possible.

6.8 Solar system with 1 collector, 1 store and after-heating:

The controller measures the temperature difference between collector sensor S1 and store sensor S2. As soon as the difference is higher or identical to the adjusted value (DO/1), the pump R1 is activated and the store is loaded. If the switch-off difference (DF/1) is underrun by that difference, the pump is switched-off. The 3rd temperature

sensor S3 can be used for thermostat function. TO is set for thermostat switch-on temperature and TF switch-off temperature in the adjustment channels. Dependent on the selected adjustment, the thermostat function works in afterheating or cooling operation.
