• Relay 1 18 = conductor R1 17 = neutral conductor N 13 = ground conductor

• Relay 2 16 = conductor R2 15 = neutral conductor N 14 = ground conductor

The mains supply is to be carried out at the terminals:

19 = neutral conductor N 20 = conductor L 12 = ground terminal

The temperature sensors (S1 up to S4) are to be connected to the following terminals with either 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 store top) 7 / 8 = Sensor 4 (e.g. Sensor return)

All Pt1000 temperature sensors are equipped with a platinum measuring element in their tip. The electrical resistance of the measuring element changes in relation to the temperature (see table in chap. 5).

The difference between FKP and FRP type sensors only lies in the cable insulation material. The insulation material of FKP type sensor cables resists a higher temperature, so that FKP type sensors should be used as collector sensors. FRP type sensors are best used as reference sensors in stores or pipes.

The controller is equipped with a RESOL VBus® for data transfer with and energy supply to external modules. The connection is carried out at the terminals marked “VBus” (either polarity). One or more RESOL VBus® modules can be connected via this data bus, such as

• GA3 large display, SD3 smart display

• DL2 datalogger

• VBus

/USB or VBus®/LAN interface adapter

• VBus®/PWM interface adapter

• AM1 alarm module

• WMZ calorimeter module

By means of a DL2 datalogger or an interface adapter, the controller can be connected to a PC or a computer network. With the RESOL ServiceCenter Software (RSC) the controller measurements can be read out, processed and visualised. The software allows easy function control of the system. For the remote parametrisation of the controller, a special software tool will be available for download, soon.

1.4 Terminal allocation in the different system layouts

System layout 1

The controller calculates the temperature difference between collector sensor S1 and store sensor S2. If the difference is larger than or identical to the adjusted switchon temperature difference (DT O), the solar pump will be operated by relay 1, and the store will be loaded until the switch-off temperature difference (DT F) or the maximum store temperature (S MX) is reached.

Sensors S3 and S4 can optionally be connected for measurement purposes. S3 can optionally be used as reference sensor for the store emergency shutdown option (OSEM). If heat quantity measurement (OHQM) is activated, sensor S4 has to be connected as return sensor. If the drainback option (ODB) is activated, relay 2 can be used to operate a booster pump by activating the booster function (OBST).

RIS3: Rise Adjustment range: 1 ... 20 K[2 ... 40 °Ra] in steps of 1 K [2 °Ra] Factory setting: 2 K [4 °Ra]

The following adjustments are used for the speciﬁc function in system layout 2.

Reference sensors for this function are S3 and S4.

In system layout 2 the controller is equipped with an additional differential control for heat exchange between two stores. The basic differential function is adjusted using the switch-on (DT3O) and switch-off (DT3F) temperature differences.

When the temperature difference exceeds the switch-on temperature difference, relay 2 switches on. If the temperature difference then falls below the adjusted switch-off temperature difference, relay 2 switches off.

Note:

The switch-on temperature difference must be at least 0.5 K [1 °Ra] higher than the switch-off tempe rature difference.

Note:

For pump speed control of the heat exchange pump, the operation mode of relay 2 (MAN2) must be set to Auto.

When the switch-on temperature difference is reached, the pump is activated at full speed for 10 seconds. Then, the speed is reduced to the minimum pump speed value (n2MN). If the temperature difference reaches the adjusted nominal temperature difference (DT3S), the pump speed increases by one step (10 %). If the difference increases by the adjustable rise value, the pump speed increases by 10 % respectively until the maximum pump speed of 100 % is reached. The response of the controller can be adapted via the parameter RIS3.

Note:

The nominal temperature difference must be at least 0.5 K [1 °Ra] higher than the switch-on tempe rature difference.

Minimum pump speed

n2MN:

Pump speed control Adjustment range: 30 ... 100 in steps of 5 % Factory setting: 30

| 10

A relative minimum pump speed can be allocated to the output R2 via the adjustment channel n2MN.

Note:

When loads which are not speed-controlled (e.g. valves) are used, the value must be set to 100 % in order to deactivate pump speed control.

Minimum temperature limitation Adjustment range:

0.0 ... 90.0 °C [30.0 ... 190.0 °F] in steps of 0.5 °C [1.0 °F] Factory setting (Arr = 2 only): MN3O: 5.0 °C [40.0 °F] MN3F: 10.0 °C [50.0 °F]

Minimum and maximum temperature limits can be set for the heat exchange function.

The maximum temperature limitation uses sensor 4 as reference sensor.

The maximum temperature limitation function provides a maximum tem perature setting, usually to reduce scald risk in a storage store. If MX3O is exceeded, relay 2 is switched off until the temperature at sensor 4 falls below MX3F.

The minimum temperature limitation uses sensor 3 as reference sensor.

The minimum temperature limitation function provides a minimum tem perature setting for the heat source in system layout 2. If the temperature at sensor 3 falls below MN3O, relay 2 is switched off until the temperature at sensor 3 exceeds MN3F.

Both switch-on and switch-off temperature differences DT3O and DT3F are valid for the maximum and minimum temperature limitation.

This function is used for protecting the upper store zone against Legionella by activating the afterheating.

Reference sensor for the thermal disinfection is S3!

Î To activate the function, select “On” in the OTD

channel.

For thermal disinfection, the temperature in the upper DHW store zone has to be monitored. This protection is ensured when, during the monitoring period (PDIS), the disinfection temperature (TDIS) is continuously exceeded for the entire heating period (DDIS). S3 is used as the reference sensor and displayed as TSTT.

If OTD is activated, PDIS will start as soon as the temperature at S3 falls below TDIS. The display channel CDIS appears, counting backwards the remaining time of PDIS. If, during the monitoring period, the temperature at S3 exceeds TDIS continuously for the duration of DDIS, thermal disinfection is considered complete and a new monitoring period begins.

If CDIS counts down to 00:00, relay 2 will be operated in order to use the afterheating for thermal disinfection. CDIS will then be replaced with a display channel DDIS showing the adjusted heating period. DDIS will start counting down the heating period as soon as TDIS is exceeded at S3. As long as DDIS is active, the temperature at S3 will be displayed as TDIS instead of TSTT.

If, during DDIS, the temperature at S3 exceeds TDIS by more than 5 K [10 °Ra], relay 2 is switched off until the temperature falls below TDIS + 2 K [4 °Ra].

If, during DDIS, the temperature at S3 falls below TDIS, the heating period will restart. DDIS can only be completed when TDIS is exceeded without interruption.

Due to the ﬂexible control logic, the exact time of thermal disinfection is not predictable. In order to set a ﬁxed time for the disinfection to be run, the starting delay SDIS must be employed:

Thermal disinfection with starting delay SDIS

Starting time Adjustment range: 00:00 ... 24:00 (o´clock) in steps of: 00:01 Factory setting: 00:00

When a starting time for thermal disinfection with starting delay is adjusted in SDIS, the thermal disinfection will be delayed until that time, even after the CDIS has counted down to 00:00. If CDIS ends, for example, at 12:00 o‘clock, and SDIS has been set to 18:30, relay 2 will be operated with a delay of 6.5 hours at 18:30 instead of 12:00.

During the waiting time, SDIS is displayed with the adjusted starting time (ﬂashing).

If, during the waiting time, the temperature at S3 exceeds TDIS for the adjusted heating period DDIS, thermal disinfection is considered complete and a new monitoring period begins.

If the starting time is adjusted to 00:00 (factory setting), the delay function is inactive.

Upon delivery, OTD is deactivated. The adjustment values PDIS, TDIS, DDIS and SDIS are displayed after the option has been activated. After the thermal disinfection function has been completed, the values will be “hidden” and the monitoring period will be displayed.

If the differences are larger than or identical to the adjusted switch-on temperature differences (DT1O / DT2O), the solar pump will be operated by relay 1, and the respective store zone will be loaded until the switch-off temperature differences (DT1F / DT2F) or the maximum store tempera-

The following adjustments are used for the speciﬁc functions in system layout 8.

Reference sensors for this function are S4 and S3.

In system layout 8, the controller is equipped with an additional differential control for heat exchange from a solid fuel boiler (e.g. woodstove). The basic differential function is adjusted using the switch-on (DT3O) and switch-off (DT3F) temperature differences.

When the switch-on difference is reached, relay 2 switches on. When the temperature difference falls below the adjusted switch-off temperature difference, relay 2 switches off.

Note:

The switch-on temperature difference must be at least 0.5 K [1 °Ra] higher than the switch-off tempe rature difference.

Note:

For pump speed control of the solid fuel boiler pump, the operation mode of relay 2 (MAN2) must be set to Auto.

Note:

The nominal temperature difference must be at least 0.5 K [1 °Ra] higher than the switch-on tempe rature difference.

A relative minimum pump speed can be allocated to the output R2 via the adjustment channel n2MN.

Note:

When loads which are not speed-controlled (e.g. valves) are used, the value must be set to 100 % in order to deactivate pump speed control.

Minimum and maximum temperature limits can be set for the solid fuel boiler.

The minimum temperature limitation uses sensor 4 as reference sensor.

The minimum temperature limitation function provides a minimum tem perature setting for the solid fuel boiler in system layout 8. If the temperature at sensor 4 falls below MN3O, relay 2 is switched off until the temperature exceeds MN3Fagain.

Both switch-on and switch-off temperature differences DT3O and DT3F are valid for the maximum and minimum temperature limitation.

Note:

In system layout 10, the parameter CMX is available without the OCC function. In system layout 10, CMX is used to set the activation temperature for the heat dump function. No other switch-on condition is needed in that case.

When the system cooling function is activated, the controller aims to keep the solar system operational for a longer time. The function overrides the maximum store temperature to provide thermal relief of the collector ﬁeld and the heat transfer ﬂuid on hot days. If the store temperature is higher than the maximum store temperature (S MX / S1MX) and the switch-on tempera- ture difference DTCO is reached, the solar system remains activated. Solar loading is continued until either the store temperature reaches 95 °C [200 °F] (emergency shutdown of the store), the temperature difference falls below the adjusted value DTCFor the collector emergency shutdown temperature EM is reached. If the system cooling function is active, is shown on the display.

Note:

This function will only be available if the collector cooling function (OCC) is deactivated.

When the store cooling function is activated, the controller aims to cool down the store during the night in order to prepare it for solar loading on the following day.

If the adjusted maximum store temperature (S MX / S1MX) is exceeded and the collector temperature falls below the store temperature, the system will be reactivated in order to cool down the store. Cooling will continue until the store temperature has fallen below the adjusted maximum store temperature (S MX / S1MX) again. A ﬁxed hysteresis of 2 K [4 °Ra] is set for this function. Reference threshold temperature differences for the store cooling function are DT O and DTF.

If no DHW consumption is expected for a longer period of time, the additional holiday cooling option OHOLcan be activated in order to extend the store cooling function. The adjustable temperature THOL then replaces the maximum store temperature (S MX / S1MX) as a switch-off temperature for the store cooling function.

The antifreeze function activates the loading circuit between the collector and the store when the temperature falls below the adjusted antifreeze temperature. This will protect the ﬂuid against freezing or coagulating. If the adjusted antifreeze temperature is exceeded by 1 K [2 °Ra], the loading circuit will be deactivated.

Note:

Since this function uses the limited heat quantity of the store, the antifreeze function should be used in regions with few days of temperatures around the freezing point. The antifreeze function will be suppressed if the store temperature falls below 5 °C [40 °F] in order to protect the store from frost damage.

The DeltaSol® BS Plus priority logic

Note:

Priority logic can be used in multi-store system layouts only (Arr = 4, 5, 6).

PRIO:

Loading priority Adjustment range: SE 1, SE 2, Su 1, Su 2, 0, 1, 2 Factory setting: Arr 4: 2 Arr 5, 6: 1

Note:

If the priority is set to Su 1 or Su 2, solar loading of the subordinate store will be aborted at once if the temperature in the priority store (store 1 for Su 1, store 2 for Su 2) falls below the adjusted maximum temperature. If, in that case, the temperature difference between the priority store and the collector is not sufﬁciently high, solar loading will be stopped completely.

Spreaded loading temperature difference

(only available if PRIO is set to SE 1 or SE 2)

DTSE:

Spread temperature difference Adjustment range: 20 ... 90 K [40 ... 160 °Ra] in steps of 1 K [1 °Ra] Factory setting: 40 K [70 °Ra]

If a multi-store system layout has been chosen, the priority logic determines how the heat is divided between the stores. Different types of priority logic are adjustable:

• spreaded loading (SE 1 and SE 2)

• successive loading (Su 1 and Su 2)

• parallel loading (0)

• store sequence control (1 and 2)

If priority SE 1 or SE 2 (only available in Arr 6) is adjusted, the subordinate store will be loaded in parallel if the temperature difference between the collector and the priority store (store 1 for SE 1, store 2 for SE 2) exceeds the adjusted value DTSE and the subordinate store has not reached its maximum temperature. Parallel loading will stop as soon as the temperature difference between the collector and the priority store falls 2 K [4 °Ra] below DTSE or the subordinate store reaches its maximum temperature. If priority Su 1 or Su 2 is adjusted, the stores are loaded successively. The subordinate store will only be loaded if the priority store (store 1 for Su 1, store 2 for Su 2) has reached its adjusted maximum temperature (S1MX or S2MX). If priority 0 is adjusted and the switch-on conditions are fulﬁlled for both stores, the stores are loaded in parallel (Arr 6), resp. in an oscillating loading (Arr 4, 5) beginning with the store with the lowest temperature. In an oscillating loading, solar loading will switch from one store to the other in steps of 5 K [10 °Ra] temperature difference between the stores. If priority 1 / 2 is adjusted, store sequence control will be activated (see below) with the corresponding store as priority store.

Storesequencecontrol

(only available if priority is set to SE 1, SE 2, 1 or 2)

tLB:

Loading break time Adjustment range: 1 ... 30 min Factory setting: 2 min

tRUN:

Loading runtime Adjustment range: 1 ... 30 min Factory setting: 15 min

Store sequence control will be activated when PRIO is set to SE 1, SE 2, 1 or 2.

If the priority store cannot be loaded, the subordinate store is checked. If useful heat can be added, it will be loaded for the “loading runtime time” (tRUN - factory setting 15 min.) After this, the loading process stops and the controller monitors the increase in collector temperature during the loading break time tLB. If it increases by 2 K [4° Ra], the break time timer starts again to allow the collector to gain more heat. If the collector temperature does not increase sufﬁciently, the subordinate store will be loaded again for the tRUN time as before.

As soon as the switch-on condition of the priority store is fulﬁlled, it will be loaded. If the switch-on condition of the priority store is not fulﬁlled, loading of the second store will be continued. If the priority store reaches its maximum temperature, sequence controlled loading will not be carried out.

If store sequence control is active and the system switches to load the priority store, the parameter tLBalso acts as a stabilisation timer, during which the switch-off condition DTF is ignored while the system operation stabilises.

Tube collector function

OTC:

Tube collector function Adjustment range: OFF / ON Factory setting: OFF

TCST:

Tube collector function starting time Adjustment range: 00:00 ... 23:45 in steps of 00:15 Factory setting: 07:00

TCEN:

TCRU:

Tube collector function runtime Adjustment range: 5 ... 500 s in steps of 5 s Factory setting: 30 s

TCIN:

Tube collector function standstill interval Adjustment range: 1 ... 60 min in steps of 1 min Factory setting: 30 min

This function helps overcome the disadvantages caused by the non-ideal sensor position with some tube collectors.

This function operates within an adjusted time frame (beginning at TCST and ending at TCEN). It activates the collector circuit pump for an adjustable runtime (TCRU) between adjustable standstill intervals (TCIN) in order to compensate for the delayed temperature measurement.

If the runtime TCRU is set to more than ten seconds, the pump will be run at 100 % for the ﬁrst ten seconds of the runtime. For the remaining runtime, the pump will be run at the adjusted minimum speed nMN.

If the collector sensor is defective or the collector is blocked, this function is suppressed or switched off.

In system layout 7 (Arr = 7) both collectors are operated independently from each other by means of this function. If the store is being loaded by one collector, the other one is nevertheless operated after the adjusted standstill time.

Note:

If the drainback option ODB is activated, TCRU will not be available. In that case, the runtime is determined by the parameters tFLL and tSTB.

WARNING! Danger of injury and system da-

mage through pressure surges!

If a drainback system is ﬁlled due to the tube collector function and the heat transfer medium enters very hot collectors, pressure surges can occur.

Î If a pressure-less drainback

sy ste m is u sed, TC ST and TCEN must be adjusted such that the system will not be ﬁlled during times of potentially strong irradiation!

If the drainback option ODBis activated, the pump will operate at 100 % speed for the adjusted ﬁlling time tFLL in order to ﬁll the system with ﬂuid from the holding tank. After tFLL, pump speed will go down to the adjusted minimum pump speed nMn. The switch-off conditions will then be ignored for the stabilisation time tSTB in order to avoid the system from shutting down prematurely.

If the function is activated, the menu items described in the following (tDTO, tFLL and tSTB) have to be adjusted:

Note:

When the drainback option ODB is activated, the cooling functions OCC, OSYC and OSTC as well as the antifreeze function OCF are not available. If OCC, OSYC, OSTC orOCFhave already been activated before, they will be deactivated again as soon as ODB is activated. They will remain deactivated, even if ODB is deactivated later on.

Additionally, the adjustment range and the factory setting of the collector emergency shutdown temperature EM changes (see the corresponding channel descriptions for further information). Previous adjustments made in these channels will be overridden and have to be entered again if ODB is deactivated later on.

The parameter tDTO is used for adjusting the time period during which the switch-on condition DT O must be permanentely fulﬁlled.

The ﬁlling time can be adjusted using the parameter tFLL. During this period, the pump runs at 100 % speed.
