Left button (

) - escape button for changing into the previous menu

Right button (

) - conrming / selecting

Lightwheel

- scrolling upwards / scrolling downwards, increasing adjustment values / reducing adjustment values

3.2 Microbutton for manual mode and holiday mode

The controller is equipped with two microbuttons for quick access to the manual mode and the holiday function. The microbuttons are located underneath the slidable housing cover, the SLider.

Microbutton

: If the microbutton is briey pressed, the controller changes

to the manual mode menu (see page 62)

Microbutton

: The microbutton is used for activating the holiday function

(see page 61). If the microbutton is pressed and held down

for approx. 3 s, the adjustment channel DAYS appears, allowing to enter the number of days for an absence. If the parameter is set to a value higher than 0, the function becomes active using the adjustments that have previously been made in the H-DAYmenu. The days will be counted backwards at 00:00. If the value is set to 0, the function is deactivated.

Electricalconnectionofahigh-efciencypump(HE pump)

Speed control of a HE pump is possible via a PWM signal / 0-10 V control. The pump has to be connected to the relay (power supply) as well as to one of the PWM A/B

outputs of the controller. In the REL adjustment channel one of the PWM control

types as well as a relay have to be selected (see page 60).

Selecting the system

Each system has pre-programmed options and adjustments which can be activated or

changed respectively if necessary. Select the system rst (see chap. 3 on page 36).

Selecting the hydraulic variant

A selection can be made between representations with or without integrated heat

exchangers (see chap. 2.6 on page 9).

External heat exchanger

This function is used to link loading circuits that are separated by an external heat exchanger.

The reference sensor as well as the reference relay can be selected. The relay is energised if one of the selected stores is being loaded and there is a

temperature difference between the sensor of the corresponding store and the sensor of the external heat exchanger.

The relay is switched off if this temperature difference falls below the adjusted switch-off difference.

In systems in which stores are equipped with their own loading pumps, the relay “external heat exchanger“ controls the primary circuit pump.

The heat exchanger is protected by a non-adjustable antifreeze function.

∆T control

The controller works as a standard differential controller. If the temperature reaches or exceeds the switch-on temperature difference, the pump switches on. When the temperature difference reaches or falls below the adjusted switch-off temperature difference, the respective relay switches off.

Note:

The switch-on temperature difference must be 0.5 K higher than the

switch-off temperature difference. The set temperature difference must be

at least 0.5 K higher than the switch-on temperature difference.

Note:

In systems with 2 stores or store loading in layers, 2 separate menus (LOAD and LOAD 2) will be displayed.

Speed control

If the temperature reaches or exceeds the switch-on temperature difference, the pump switches on at 100% speed for 10 s. Then, the speed is reduced to the minimum pump speed value.

If the temperature difference reaches the adjusted set temperature difference, the

pump speed increases by one step (10 %). The response of the controller can be

adapted via the parameter Rise. If the difference increases by the adjustable rise value RIS, the pump speed increases by 10 % until the maximum pump speed of 100% is reached. If the temperature difference decreases by the adjustable rise value, pump speed will be decreased by one step.

Note: To enable speed control, the corresponding relay has to be set to AUTO, MIN, MAX, or ADAP (MAN channel) and relay control to PULS, PSOL, PHEA or 0-10 V (adjustment channel REL).

Priority logic

Priority logic can be used in 2-store systems or systems with store loading in layers only and determines how the heat is divided between the stores.

PRIO : Store 1 / store base PRIO 2 : Store 2 / store top The store which has been adjusted to 1 is considered as the priority store. If both stores have been adjusted to an identical value, they will be loaded in parallel.

Store maximum temperature and Sensor store maximum temperature

If the store temperature reaches the adjusted maximum temperature, the store will no longer be loaded in order to avoid damage caused by overheating. If the maximum store temperature is exceeded,

is displayed.

collector temperature is exceeded,

is displayed (ashing).

Note:

If the drainback option is activated, the adjustment range of the collector

emergency temperature is changed to 80 … 95 °C. Factory setting will be 95 °C.

Note: In systems with east- / west collectors 2 separate menus (COL and COL 2) will be displayed.

WARNING!

Risk of injury! Risk of system damage by pressure surge!

If water is used as the heat transfer uid in pressureless systems,

water will boil at 100 °C.

Î In pressureless systems with water as the heat trans-

feruid,donotsetthecollectorlimittemperature

Collector cooling

The collector cooling function keeps the collector rise temperature within the

operating range by heating the store. If the store temperature reaches 95 °C the

function will switch off for safety reasons. When the store temperature exceeds the adjusted maximum store temperature, the solar system switches off. If the collector temperature increases to the adjusted maximum collector temperature, the solar pump is switched on until the collector temperature falls below the maximum collector temperature. The store tempera-

ture may then exceed the maximum temperature, but only up to 95 °C (emergency shutdown of the store).

If the collector cooling is active,

Collector minimum temperature

The minimum collector temperature is the minimum switch-on temperature which must be exceeded for the solar pump (R1 / R2) to switch on. If the collector tem-

perature falls below the adjusted minimum temperature,

is displayed (ashing).

Note: In systems with east- / west collectors 2 separate menus (COL and COL 2) will be displayed.

Tube collector function

This function is used for improving the switch-on behaviour in systems with

non-ideal sensor positions (e. g. with some tube collectors).

This function operates within an adjusted time frame. It activates the collector circuit pump for an adjustable runtime between adjustable pauses in order to compensate for the delayed temperature measurement.

If the runtime is set to more than 10 s, the pump will be run at 100 % for the rst

10 s of the runtime. For the remaining runtime, the pump will be run at the adjusted minimum speed.

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

2-collector systems

In 2-collector systems, the tube collector function is available for each individual

collector eld.

In 2-collector systems, the tube collector function will affect the inactive collector

eld only. The solar pump of the active collector eld will remain switched on until the switch-off conditions are fullled.

Note:

If the drainback option is activated, the tube collector function will not be available.

Antifreeze function

The antifreeze function activates the loading circuit between the collector and the

store when the temperature falls below the adjusted temperature CFR O. This will protect the uid against freezing or coagulating. If CFR F is exceeded, the solar pump will be switched off again.

The antifreeze function will be suppressed if the store temperature of the selected store falls below 5 °C. In 2-store systems, the function then switches to the second store or, in the case of store loading in layers, to the upper store zone. If the temperature of the second store (or of the upper store zone respectively) also falls below 5 °C, the system will be switched off.

Note: In systems with east- / west collectors 2 separate menus (COL and COL 2) will be displayed.

Note:

Since this function uses the limited heat quantity of the store, the anti-

freeze function should be used in regions with few days of temperatures around the freezing point.

Drainback option

In a drainback system the heat transfer uid will ow into a holding tank if solar loading does not take place. The drainback option initiates the lling process if solar

loading is about to start. If the drainback option is activated, the following adjustment can be made:

Note: A drainback system requires additional components such as a holding tank. The drainback option should only be activated if all components required are properly installed.

Time period - switch-on condition The parameter tDTO is used for adjusting the time period during which the

switch-on condition must be permanently fullled.

Filling time

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

Stabilisation The parameter tSTB is used for adjusting the time period during which the switch-

off condition will be ignored after the lling time has ended.

tor eld and if no cooling function is activated.

Note: If the drainback function ODB is activated, the factory settings of the parameters DT O, DT F and DT S will be adapted to values suiting drainback systems:

DT O = 10 K DT F = 4 K DT S = 15 K

Additionally, the adjustment range and the factory setting of the collector emergency shutdown CEM will change:

Adjustment range: 80 … 120 °C; Factory setting: 95 °C

Adjustments previously made in these channels will be overridden and have to be entered again if the drainback option is deactivated later on.

Note:

If the holiday function is activated, the drainback option will not be available.

Booster function

This function is used for additionally switching on a second pump when lling the system. When solar loading starts, R2 is energised in parallel to R1. After the lling

time has elapsed, R2 switches off.

Note: The booster function is available in systems 1, 2, 3, 8, and 9 only.

Successive loading option

Successive loading means that the priority store will be loaded up to its maximum temperature. If it is reached, the second store will be loaded. If the temperature of

the rst store falls below the store set temperature, the second store will no longer

Spreaded loading option

In 2-store systems with 2 pumps, a spreaded loading function can be activated: As soon as the adjustable spread difference DTSE between the collector and the priority store is reached, the second store will be loaded in parallel unless it is blocked. If the temperature difference falls by 2 K below DTSE, the pump is switched off. The collector temperature has to be higher than the store temperature.

Loading logic

In systems with 2 stores or store loading in layers, store sequence control can be adjusted.

In 1-store systems, only the menu item Pump delay will be available.

Store sequence control

If the priority store cannot be loaded, the subordinate store will be checked. If useful heat can be added, it will be loaded for the circulation time.

After this, the loading process stops and the controller monitors the increase in

collector temperature during the loading break time. If it increases by 2 K, the break

time timer starts again to allow the collector to gain more heat. If the collector

temperature does not increase sufciently, the subordinate store will be loaded

again for the circulation time.

As soon as the switch-on condition of the priority store is fullled, it will be loaded. If the switch-on condition of the priority store is not fullled, loading of the second

store will be continued. If the priority store reaches its set temperature, store sequence control will not be carried out.

The minimum runtime of each loading process is 3 min.

In systems with 2 stores or store loading in layers, all stores / store zones will be

loaded to their set temperature (according to their priority and store sequence

control). Only when all stores / store zones have exceeded their set temperature

will they be loaded up to their maximum temperatures, again according to their priority and store sequence control.

If store sequence control is active and the system switches to load the priority store, the parameter Loading break also acts as a stabilisation time, during which the switchoff temperature difference will be ignored while the system operation stabilises.

Overrun

By means of this function, store loading continues after the temperature difference between the collector and the store has fallen below the switch-off difference. It

switches off if the temperature difference between the allocated ow and return

sensors exceeds switch-off difference DT(2)F.

Cooling functions

Different cooling functions can be activated: system cooling, store cooling and heat dump.

Note:

If the temperature at the store sensor reaches 95 °C, all cooling functions will be blocked. The switch-on hysteresis is -5K.

Note:

If one of the cooling functions or the antifreeze function is activated, the

drainback option will not be available.

System cooling

The system cooling function 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 eld and the heat transfer uid on hot days.

If the store temperature is higher than the adjusted maximum store temperature and the switch-on temperature difference DTO is reached, the solar pump remains switched on or will be switched on. Solar loading is continued until either the temperature difference falls below the adjusted value DTF or the collector emergency shutdown temperature is reached.

In 2-store systems the sequence of the stores can be adjusted. If the system cooling function is active,

is shown on the display (ashing).

Note:

This function will only be available if the collector cooling function, the heat dump function, and the drainback option are not activated.

Store cooling

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 is exceeded and the collector temperature falls below the store temperature, the system will be reactivated in order to cool down the store.

DTCO and DTCF are used as the reference temperature differences.

Heat dump

The heat dump function can be used to direct excess heat generated by strong

solar irradiation to an external heat exchanger (e. g. fan coil) in order to keep the

collector temperature within the operating range. The heat dump function can either use an additional pump or valve (OTPUM ON =

pump logic, OTPUM OFF = valve logic).

If the collector temperature falls by 5 K below the adjusted collector overtemperature, the relay will be switched off. In the variant pump, the heat dump function works independent from solarloading.

Variant valve:

The allocated relay will be energised in parallel to the solar pump, if the collector temperature reaches the adjusted collector overtemperature. If the collector tem-

perature falls by 5 K below the adjusted collector overtemperature, the relay will

be switched off.

If one of the store temperatures exceeds its respective maximum temperature by

more than 5 K while the heat dump function is being active, the function will be

deactivated. If the temperature falls below this value by the hysteresis maximum store temperature (HYST(2) in LOAD(2)), the heat dump function is will be available again.

Note:

The thermostat function works independently from the solar operation and can e. g. be used for using surplus energy or for afterheating.

• AH O < AH F thermostat function for afterheating

• AH O > AH F thermostat function for using surplus energy

In order to block the thermostat function for a certain period, there are 3 time

frames t1 … t3. The switch-on and switch-off times can be adjusted in steps of 15

min. If the switch-on and the switch-off times are identical, the time frame is inactive. If the thermostat function is supposed to run from 06:00 a.m. and 09:00 a.m. only,

adjust t1 O to 06:00 a.m. and t1 F to 09:00 a.m.

The rst time frame is factory set from 06:00 to 22:00.

Holiday function

The holiday function is used for operating the system when no water consumption is expected, e. g. during a holiday absence. This function cools down the system in order to reduce the thermal load.

Only if the holiday function has been activated with the parameter DAYS will the adjustments described in the following become active.

3 cooling functions are available: system cooling, store cooling and store heat dump.

The system cooling function 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 eld and the heat transfer uid on hot days.

The system cooling option can be adjusted with the parameter OSYC. The function uses the adjustable switch-on and switch-off temperature differences DTO and DTF from the BEL(2) menu.

The store cooling option is activated by default and can be deactivated with the parameter OSTC. Store cooling starts when the store temperature exceeds the collector temperature by the adjustable value DTCO. It switches off if the store temperature reaches THOL or if the temperature difference falls below DTCF. The parameter THOL is used for adjusting the temperature for store cooling.

The store heat dump function can be used to direct excess heat generated by strong solar irradiation from the store to an external heat exchanger (e. g. fan

coil) or radiator in order to prevent the collectors from overheating. The store

heat dump function is independent of the solar system and can be activated with the parameter OHDPS. The function uses the adjustable switch-on and switch-off temperature differences OTSPO and OTSPF. If temperature measured at the sensor selected in HDREL reaches the switch-on temperature, the relay selected in HDREL will be energised until the temperature difference falls below the switch-off value. In systems with afterheating, the parameter AHOFF can be used for switching off the afterheating during a holiday absence.

The parameter DAY S can be used for entering the number of days for a holiday absence.If the parameter is set to a value higher than 0, the function becomes active using the adjustments that have previously been made in the H-DAY menu. The days will be counted backwards at 00:00. If the value is set to 0, the function is deactivated.

Note: The parameter DAY S can be accessed via the microbutton only (see

Thermal disinfection

This function helps to contain the spread of Legionella in DHW stores by systematically activating the afterheating.

One sensor and one relay can be selected for this function. For thermal disinfection, the temperature at the allocated sensor has to be moni-

tored. This protection is ensured when, during the monitoring period, the disinfection temperature is continuously exceeded for the entire disinfection period.

The monitoring period starts as soon as the temperature at the allocated sensor falls below the disinfection temperature. When the monitoring period ends, the allocated reference relay activates the afterheating. The disinfection period starts, if the temperature at the allocated sensor exceeds the disinfection temperature.

Thermal disinfection can only be completed when the disinfection temperature is exceeded for the duration of the disinfection period without any interruption.

Starting time delay

If the starting delay option is activated, a starting time for the thermal disinfection with starting delay can be adjusted. The activation of the afterheating is then delayed until that starting time after the monitoring period has ended.

If the monitoring period ends, for example, at 12:00 o'clock, and the starting time has been set to 18:00, the reference relay will be energised with a delay of 6 hours at 18:00 instead of 12:00 o'clock.

Flow rate monitoring

The ow rate monitoring function can be used for detecting malfunctions that impede the ow rate and for switching off the corresponding store. This will prevent

system damage, e. g. through a dry run of the pump.

If the allocated relay is energised, the ow rate will be monitored at the allocated sensor. An error message will appear when no ow rate is detected at the allocated

sensor after the delay time has passed.

If the shutdown option has been activated for the ow rate monitoring function, the

store being loaded will be blocked for any further loading until the error message has been acknowledged. The next store free for loading will be loaded instead, if possible. When the error message has been acknowledged, the monitoring function will be active again.

Note: If the ow rate sensor used is removed, ow rate monitoring will be deactivated.

Pressure monitoring

Note:

The pressure monitoring function will only be available when an RPD type Grundfos Direct Sensor™ is connected.

The pressure monitoring function can be used for detecting overpressure or low pressure conditions inside the system, and if necessary to shut down the affected system components in order to avoid system damage.

Overpressure

If the system pressure exceeds the adjustable switch-on value, an error message will appear.

If the shutdown option has been activated for the overpressure monitoring function, the solar system will be shut down as well in the case of a fault condition.

When the pressure reaches or falls below the adjustable switch-off value, the system is switched on again.

Note:

For the overpressure monitoring function, the

switch-on value must be at least 0.1 bar higher than the switch-off value. The adjustment ranges will automatically adapt to that.

Low pressure (leakage)

If the system pressure falls below the adjustable switch-on value, an error message will appear.

If the shutdown option has been activated for the low pressure monitoring function, the solar system will be shut down as well in the case of a fault condition.

When the pressure reaches or exceeds the adjustable switch-off value, the system is switched on again.

Note: For the low pressure monitoring function, the switch-off value

must be at

least 0.1 bar higher than the

switch-on value

. The adjustment ranges will

automatically adapt to that.

Function control

∆T control

This function is used for monitoring the temperature difference between the collector and the store. The message ∆T too high is shown, if solar loading has been

carried out for a period of 20 minutes with a differential higher than 50 K. Normal

operation is not aborted or inhibited, but the system should be checked for the cause of the warning.

Possible causes are:

• pump power too weak

• blocked system components

• circulation problems in the collector

• air inside the pipework

• defective valve/ defective pump

Night circulation

This function can be used for detecting thermal circulation inside the solar circuit that leads to an unwanted cooling of the store. A warning message will appear when the following condition has been detected for at least 1 min during the period be-

tween 11 p.m. and 5 a.m.:

• collector temperature exceeds 40 °C

The delay time of 1 min ensures that the message is not triggered by short-term fault conditions.

Possible causes are:

• defective non-return valves

• defective valve

• wrongly adjusted time

Flow and return pipe interchanged

This function is used for detecting an interchange of the ow and return pipe or a

badly placed collector sensor. For this purpose, the collector temperature is monitored for plausibility during the switch-on phases of the solar pump. An error mes-

sage will appear, if the plausibility criteria have not been met 5 times in a row.

Maximum store temperature

This function is used for detecting and indicating if the adjusted maximum store temperature has been exceeded. The controller compares the current store temperature to the adjusted maximum store temperature, thus monitoring the store loading circuits.

The maximum store temperature is considered exceeded when the temperature measured at the store sensor exceeds the adjusted maximum store temperature by

at least 5 K. The monitoring becomes active again as soon as the store temperature

falls below the adjusted maximum store temperature. The channels ST1, ST2 can be used for selecting the stores to be monitored. The

number of exceedances is displayed in the ST1(2)MX channels. A possible cause for an unwanted exceedance of the maximum store temperature is a defective valve.

Sensors

The product range includes high-precision platinum temperature sensors, atscrew

sensors, outdoor temperature sensors, indoor temperature sensors, cylindrical clipon sensors, also as complete sensors with immersion sleeve.

Overvoltage protection device

In order to avoid overvoltage damage at collector sensors (e.g. caused by local

lightning storms), we recommend installing the overvoltage protection RESOL SP10.

VFS and RPS Grundfos Direct Sensors™

The RPS Grundfos Direct Sensor™ is an analogue sensor that measures both temperature and pressure.

The VFS Grundfos Direct Sensor™ is an analogue sensor that measures both temperature and ow rate.

V40owmeter

The RESOL V40 is a measuring instrument for detecting the ow of water or water/ glycol mixtures. After a specic volume has passed, the V40 reed switch sends an

impulse to the calorimeter. The heat quantity used is calculated by the calorimeter using these impulses and the measured temperature difference with the help of

pre-dened parameters (glycol type, concentration, heat capacity, etc.).

12.2 VBus

accessories

Smart Display SD3 / Large Display GA3

The RESOL Smart Display is designed for simple connection to RESOL controllers with RESOL VBus

. It is used for visualising data issued by the controller: collector

temperature, store temperature and energy yield of the solar thermal system. The

use of high-efciency LEDs and lter glass assures a high optical brilliance and good

readability even in poor visibility conditions and from a larger distance. An additional power supply is not required. One module is required per controller.

The RESOL GA3 is a completely mounted large display module for visualisation

of collector- and store temperatures as well as the heat quantity yield of the solar system via one 6-digit and two 4-digit 7-segment-displays. An easy connection to all controllers with RESOL VBus® is possible. The front plate is made of antireective

lterglass and is printed with a light-resistant UV-lacquering. The universal RESOL

VBus® allows the parallel connection of 8 large displays as well as additional VBus® modules.

AM1 Alarm module

The AM1 Alarm Module is designed to signal system failures. It is to be connected to the VBus® of the controller and issues an optical signal via the red LED if a failure has occurred. The AM1 also has a relay output, which can e. g. be connected to a

building management system (BMS). Thus, a collective error message can be issued

in the case of a system failure.

DL3 Datalogger

Be it solar thermal, heating or DHW heat exchange controllers – with the DL3 you can easily and conveniently log system data of up to 6 RESOL controllers. Get

a comprehensive overview of all controllers connected with the large full graphic display. Transfer data with an SD memory card, or use the LAN interface to view and process data on your PC.

DL2 Datalogger

This additional module enables the acquisition and storage of large amounts of data

(such as measuring and balance values of the solar system) over a long period of time. The DL2 can be congured and read-out with a standard Internet browser

via its integrated web interface. For transmission of the data stored in the internal memory of the DL2 to a PC, an SD card can be used. The DL2 is appropriate for all controllers with RESOL VBus

. It can be connected directly to a PC or router for remote access and thus enables comfortable system monitoring for yield monitoring or for diagnostics of faults.

VBus.net

The Internet portal for easy and secure access to your system data. VBus.net is all about the data of your RESOL controller. Live data of your system,

customized lter settings and much more await you.

12.3 Interface adapters

VBus

/ USB & VBus® / LAN interface adapters

The VBus® / USB interface adapter is the interface between the controller and a personal computer. With its standard mini-USB port it enables a fast transmission of system data for processing, visualising and archiving data via the VBus

. A full version of the RESOL ServiceCenter software is included. The VBus

/ LAN interface adapter is designed for the direct connection of the controller to a PC or router. It enables easy access to the controller via the local network of the owner. Thus, controller access and data charting can be effected from every workstation of the network. The VBus

/ LAN interface adapter is suitable for all controllers equipped with a RESOL VBus®. A full version of the RESOL ServiceCenter software is included.
