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: 19 = neutral conductor N 20 = conductor L 12 = ground clamp

net clamps

fuse

consumer clamps

Sensor clamps

hanging

ﬁxation

earthing clamps

Electrostatic discharge can lead to damages of electronic components!

Dangerous voltage on contact!

Please note:

The relays are semi-conductor-relays for pump speed control - they need a minimum load of 20 W (power consumption of the consumer) for faultless function. When connecting auxiliary relays, motor valves, etc. are individually to the condenser which is enclosed in the mounting material, must be connected parallely to the relevant relay output. Attention: for connection of auxiliary relays or valves, the minimum pump speed must be adjusted to 100 %.

3. Commissioning On commissioning you have to adjust primarily the system scheme

1. 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 with factory settings. The preadjusted system scheme is Arr 1.

2. - select Arr

- change into -mode (see 2.1)

- select the system scheme by Arr-characteristics

- adjustment is saved by pressing button

Now the controller is ready for operation and should enable an optimum operation of the solar system by the factory settings made.

4.1.7 Heat quantity balancing

OHQM:Heat quantity balan-

cing Adjustment range: OFF ... ON Factory setting: OFF

A heat quantity balancing is possible for the basic systems (Arr) 1, 3, 4 and 5 in conjunction with a ﬂowmeter. You just have to activate the option heat quantity balancing in the channel OHQM

The volume ﬂow readable at the ﬂowmeter (l/min) must be adjusted in the channel FMAX. Antifreeze type and concentration of the heat transfer medium are indicated on the channels MEDT and MED%.

Type of antifreeze:

0 : water 1 : propylene glycol 2 : ethylene glycol 3 : Tyfocor® LS / G-LS

The heat quantity transported is measured by the indication of the volume ﬂow and the reference sensor of feed ﬂow S1 and return ﬂow S4. It is shown in kWh-parts in the indication channel kWh and in MWh-parts in the indication channel MWh. The sum of both channels form the total heat output.

The heat quantity added up can be reset. As soon as one of the display channels of the heat quantity is selected, the symbol is permanently shown on the display. The button SET (3) must pressed for approx. 2 seconds in order to get back into the RESET-mode of the counter. The display-symbol is ﬂashing and the value for heat quantity will be set to 0. In order to ﬁnish the RESET-procedure, the button must be pressed in order to conﬁrm.

In order to interrupt the RESET-procedure, no button should be pressed for about 5 seconds. The controller returns automatically into the indicaton mode.

FMAX: Volume ﬂow in l/min Adjustment range 0 ... 20 in steps of 0,1 Factory setting 6,0

MED%: Concentration of antifreeze in (Vol-) % MED% is blinded out by MEDT 0 and 3. Adjustement range 20 ... 70 Factory setting 45

4.1.6 Operating hours counter

The operating hours counter adds up the solar operating hours of the respective relay (h P / h P1 / hP2). Full hours are shown on the display.

The operating hours added up can be reset. As soon as one operating hours channel is selected, the symbol in permanently shown on the display. The button SET (3) must pressed for approx. 2 seconds in order to get back into the RESET-mode of the counter. The display-symbol is ﬂashing and the operating hours will be set to 0. In order to ﬁnish the RESET-procedure, the button must be pressed in order to conﬁrm.

In order to interrupt the RESET-procedure, no button should be pressed for about 5 seconds. The controller returns automatically into the indication mode.

4.1.8 ∆T-regulation

Please note: Switch-on temperature difference DO must

be at least 1 K higher than the switch-off temperaturedifference DF.

DT O / DT1O / DT2O / DT3O:

Switch-on temperature

Adjustment range 1,0...20,0 K

Factory setting 6.0

DT F / DT1F / DT2F / DT3F:

Switch-off temperature diff. Adjustment range 0,5 ... 19,5 K Factory setting 4.0 K

4.1.9 Maximum store temperature

If the adjusted maximum temperature is exceeded, a further loading of the store is stopped so that a damaging overheating can be avoided. If the maximum store

temperature is exceeded, in the display is shown and . Please note: The controller is equipped with a securityswitch-off of the store, which avoids a further loading of the store if 95 °C is reached at the store.

S MX / S1MX / S2MX: Maximum store temp. Adjustment range 2..95 °C Factory setting 60 °C

DT S / DT1S / DT2S / DT3S:

Nominal temperature difference Adjustment range 1,5..30,0 K Factory setting 10.0

RIS / RIS1 / RIS2 / RIS3: Raise Adjustment range 1 ... 20 K Factory setting 2 K

Primarily the controller works in the same way as a standard differential controller. If the switch-on difference (DT O / DT1O / DT2O) is reached, the pump is activated and after having got an impulse (10 s) a minimum pump speed (nMN = 30 %) is run. If the adjusted nominal value of the temperature difference (DT S / DT1S / DT2S / DT3S) is reached, the pump speed is increased by one step (10%). If the difference increases by 2 K(RIS / RIS1 / RIS2 / RIS3), the pump speed is increased by 10 % respectively until the maximum pump speed of 100 % is reached. The response of the controller can be adapted by means of the parameter „Anstieg“ (raise). If the adjusted swithc-off temperature is underrun (DT F / DT1F /

DT2F), the controller switches-off.

Maximum temperature limitation

The controller is equipped with an independent temperature differential regulation for which minimum and maximum temperature limations as well as corresponding switch-on and -off temperatures can be separately adjusted. Only possible for Arr = 2 and 8 (e.g. for solid hot fuel boilers or heat exchange regulation.

4.1.12 System cooling

If the adjusted maximum store temperature is reached, the solar system switches-off. If now the collector temperature raises to the adjusted maximum collector temperature (CMX / CMX1 / CMX2), the solar pump remains activated until this limit temperature value is again underrun. The store temperature might continue to raise (subordinated active maximum store temperature), but only until 95 °C (emergency shutdown of the store). If the store temperature is higher than the maximum store temperature (S MX / S1MX / S2MX) and the collector temperature is by at least 5K lower than the store temperature, the solar system remains activated until the store is again cooled down by the collector and the tubes under the adjusted maximum temperature (S MX / S1MX / S2MX)(only by activated OREC function).

In case of active system cooling on the display is shown (ﬂashing). Due to the cooling function the solar system can be kept operable for a longer period on hot summer days and a thermal release of the collector and the heat transfer medium is ensured as well.

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. If the minimum temperature is underrun, in the display is

4.1.11 Limit collector temperature Collector emergency shutdown

If the adjusted collector limit temperature (EM / EM1 / EM2) is exceeded the solar pump (R1/R2) is deactivated

in order to avoid a damaging overheating of the solar components (collector emergency 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 (ﬂashing).

EM / EM1 / EM2: Limit collector temperature Adjustment range 110 ... 200 °C, Factory setting 140 °C

The antifreeze function activates the loading circuit between collector and store if the adjusted antifreeze function is underrun in order to protect the medium that it will not freeze or „get thick“. If the adjusted frost protection temperature is exceeded by 1 °C, the loading circuit will be deactivated.

Please note: As there is only a limited heat quantity of the store available for this function, the anti freeze function should only be used in regions with few days of temperatures around freezing point.

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 store can be charged, this is effected by the so-called „oscilating charge time“ (tRUN). After termination of the oscilating charge time, loading is stopped. The controller controls the increase in collector temperature. If it increases by the collector rising temperature (∆T-Col 2 K, ﬁxed software value), the expired break time is again reset to zero and the oscilating break time starts again. If the switch-on conditions of the priority store is not reached, the loading of the lower-ranking store is continued. If the priority switch has reached its maximum temperature, the oscilating charge is not effected.

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

4.1.17 Tube collector special function

If the controller measures an increase of 2 K compared to the collector temperature stored at last, the solar pump is switched-on to 100 % for about 30 seconds. After expiration of the solar pump runtime the current collector temperature is stored as new reference value. If the measured temperature (new reference value) is again exceeded by 2 K, the solar pump again switches-on for 30 seconds. If the switch-on difference between collector and store is again exceeded during runtime of the solar pump or the standstil of the system, the controller automatically switches over to solar charging. If the collector temperature drops by 2 K during standstill, the switch-on value for the special tube collector function will be recalculated.

O TC: Tube collector special function Adjustment range: OFF ... ON Factory setting: OFF

4.1.16 Recooling function

If the adjusted maximum store temperaute (S MX, S1MX) is reached, the solar pump remains activated in order to avoid an overheating of the collector. The temperature of the ﬁrst store might continue to increase but only up to 95 °C (emergency shutdown of the store). In the evening the solar system continues running until the store is cooled down to the adjusted maximum store temperature via collector and pipes.

The priority logic of the controller DeltaSol® BS Pro:

The above-mentioned options and parameter only have a meaning in multi-store systems (system Arr = 4, 5, 6). If priority 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 Arr= 5, 6 parallel loading is also possible.
