Step-by-step parameterisation
The DeltaSol® BX Plus is a controller that offers a broad variety of functions
to the user. At the same time, the user has a lot of freedom in configurating them.
Therefore, to set up a complex system, careful planning is required.We recommend
drawing a sketch of the system first.
If planning, hydraulic construction and electrical connection have all been carried
out successfully, proceed as follows:
en
1. Running the commissioning menu
The commissioning menu is run after the first connection and after every reset. It
will request the following basic adjustments:
• Menu language
• Temperature unit
• Volume unit
• Pressure unit
• Energy unit
• Time
• Date
• Solar system
• Hydraulic variant
At the end of the commissioning menu, a safety enquiry follows. If the safety enquiry is confirmed, the adjustments are saved.
For further information about the commissioning menu see page 14.
2. Registering sensors
If flowmeters, Grundfos Direct Sensors™ and/or external extension modules are
connected, these have to be registered in the In-/Outputs menu.
For further information about the registration of modules and sensors see page
67.
3. Activating solar optional functions
The basic solar system has been adjusted during commissioning. Now, optional
functions can be selected, activated and adjusted.
Free relays can be allocated to optional functions which require a relay. The controller always suggests the numerically smallest free relay.

5.1
Basic systems and hydraulic variants
System
The selection of the basic solar system is one of the most important adjustments
and is thus requested already in the commissioning menu.
First, the basic system is adjusted by means of the number of stores and collectors
fields, then the hydraulic variant.
The selected system is visualised by the corresponding number of store and collector symbols. The figure to the left shows system 6 which consists of 3 stores and 2
collector fields ("east- / west collectors").
The controller is preprogrammed for 7 basic systems. The selection depends on
the number of heat sources (collector fields) and heat sinks (stores, pool). Factory
setting is system 1.
Variant
en
System 0: no solar system
System 1: 1 collector field
- 1 store
System 2: east- / west collectors - 1 store
System 3: 1 collector field
- 2 stores
System 4: east- / west collectors - 2 stores
System 5: 1 collector field
- 3 stores
System 6: east- / west collectors - 3 stores
System 7: 1 collector field
- 4 stores
A solar system with store charging in layers is implemented as a 2-store
system (store top = store 1; store base = store 2).
16
The hydraulic variant refers to the different actuators that are to be controlled.
They are visualised on the display by means of symbols, when the variant is selected. The upper symbol indicates the actuator belonging to the collector fields, the
lower one the actuators belonging to the stores.
The exemplary figure shows the display indicated when system 6, variant 2 has
been selected. In this case, each collector field has a 2-port valve, the stores are
loaded by means of pump logic.
For each variant, the controller allocates the corresponding relays and sensors.The
allocations of all combinations are shown in chap. 5.2.

Basic solar settings
In this menu, all basic settings for the solar part of the arrangement can be adjusted.
In this menu, the hydraulic system, which is the basis for the arrangement, can be
adjusted. The setting is divided into systems and variants.
Both system and variant have usually been adjusted during commissioning. If the
setting is changed later on, all adjustments for the solar part of the arrangement
are set back to their factory settings.
If the change causes the solar system to require a relay that has been allocated to
an arrangement function before, all adjustments made in the non-solar function will
be set back to their factory settings as well.
The following items in the Solar / Basic settings menu will adjust to the system
selected.
Collector (1, 2)
en
First of all, the basic solar system can be selected according to the number of
stores and collector fields in use. The corresponding numbers are indicated on
the display.
The exemplary figure shows system 6 with its 3 stores and 2 collector fields
(east- / west collectors).
In systems with 2 collector fields, 2 seperate menu items (Collector 1 and Collector 2) are displayed instead of Collector.
For each collector field, a collector minimum limitation and a collector emergency
shutdown temperature can be adjusted.
Solar / Basic settings / Collector (1, 2)
When the basic system has been selected and confirmed, the hydraulic variant can
be selected. The variant is visualised on the display by means of pump and valve
symbols. The exemplary figure shows variant 2 of system 6 with a 2-port valve and
a pump. For an overview of the basic systems and their variants see page 17.
The controller supports up to 2 collector fields and up to 4 solar stores (with 2
collector fields only up to 3 solar stores).

For each store, an individual ∆T control, a set and a maximum temperature, the
priority, a hysteresis, a rise value, a minimum runtime and a minimum pump speed
can be adjusted.
In multi-store-systems with differing Store set / Maximum store temperatures, all
stores are loaded up to their Stset temperatures first (according to their priority
and the store sequence control). Only when all stores have exceeded Stset will
they be loaded up to their Stmax temperatures, again according to their priority
and the store sequence control.

Store sequence control:
If the priority store cannot be loaded, the subordinate store next in priority is
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 Load. break. 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 sufficiently, the subordinate store will
be loaded again for the Circ. 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,
store sequence control will not be carried out.
If store sequence control is active and the system switches to load the priority
store, the parameter Load. break also acts as a stabilisation time, during which the
switch-off condition is ignored while the system operation is stabilising.
Solar optional functions
In this menu, optional functions can be selected and adjusted for the solar part of
the arrangement.
By selecting Add new function, different pre-programmed functions can be selected.The kind and number of optional functions offered depends on the previous
adjustments.

When a function is selected, a sub-menu opens in which all adjustments required
can be made.
With this menu item, a relay and, if necessary, certain system components can be
allocated to the function.
The menu item Relay selec. is available in all optional functions. Therefore, it will
not be explained in the individual function descriptions.
With this menu item, a relay can be allocated to the function. All free relays are
available for selection.

If Free is selected, the function will run normally in the software but will not
operate a relay.
In the sub-menu Controller, all free relays of the controller are displayed. If external modules are connected and registered, their relays will be displayed in corresponding sub-menus.
With the menu item Function, an optional function already selected can be temporarily deactivated or re-activated respectively. In this case, all adjustments remain
stored, the allocated relays remain occupied and cannot be allocated to another
function.
en
When a function has been selected and adjusted, it will appear in the Opt. functions menu above the menu item Add new function.
This allows an easy overview of functions already activated.
An overview about which sensor has been allocated to which component and

Bypass
The Bypass function can be used for avoiding an energy loss from the store directly after loading has started.The still cold heat transfer medium in the pipework
is diverted through a bypass past the store. Once the pipe is warm enough, the
store can be loaded.

the Bypass switch-on temperature difference, the bypass relay operates the
valve and solar loading starts.
When the valve variant is selected, the option Inverted is additionally available.
When the Inverted option is activated and the bypass circuit becomes activated,
the relay switches on. If the temperature difference between the Bypass sensor

The CS bypass function is a different possibility to activate the collector circuit.
To enable the use of the CS bypass function, a CS10 irradiation sensor has to be
connected.
When the CS bypass function is activated, the irradiation value is the switch-on
condition for the collector circuit.
The relay remains switched on if the irradiation value is exceeded for the Delay
time. When solar loading begins or the irradiation value remains below the switchon value for the delay time, the relay is switched off.
When the option Stmax off is activated, collector circuit activation is suppressed
as long as all store temperatures are above their respective maximum temperatures.
Note:
If both the CS bypass and the bypass function are activated, the CS bypass
will only affect the bypass.

Description
Factory setting
This function is used to link loading circuits that are separated by an external heat
exchanger.
The allocated 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 solar flow.
Any number of the solar stores can be selected.
The relay is switched off if this temperature difference falls below the adjusted
switch-off difference.
In contrast to the bypass function, a differential control between Sensor HX and
the store temperature can be carried out by means of the heat exchanger relay.
The reference sensor can be arbitrarily allocated. In systems in which stores are
equipped with their own loading pumps, the heat exchanger relay controls the
primary circuit pump.
35
en
Solar / Opt. functions /Add new function / CS bypass
The heat exchanger is protected by a non-adjustable antifreeze function.
When the temperature at the Reference sensor ext. HX falls below the non-adjustable antifreeze temperature (10 °C), the controller will activate the secondary
pump at 100 % speed. The antifreeze function will use heat from the store that has
the highest temperature. When all stores have reached 10 °C, the secondary pump
will be switched off. If the temperature at the Reference sensor ext. HX exceeds
the antifreeze temperature by 2 K, the secondary pump will be switched off.
The heat exchanger antifreeze function works independently from solar loading.
Note:
Because of the special hydraulics in systems with 2 collectors, the Target
temperature function will not work properly there.
If the runtime is set to more than 10 s, the pump will be run at 100 % for the first
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 field.
The tube collector function will remain inactive for a collector field which is used
for solar loading.

then will the standard pump speed control start to operate. If the temperature at
the allocated sensor changes by the adjusted Rise value, the pump speed will be
adjusted correspondingly.
If the Ext. HX function (see page 35) has been activated, too, the target temperature control will pause while the external heat exchanger is loaded. While the external heat exchanger is loaded, its own pump speed control will come into effect.

The Antifreeze function activates the loading circuit between the collector and
the store when the collector temperature falls below the adjusted Antifreeze
switch-on temperature.This will protect the fluid against freezing or coagulating.
If the Antifreeze switch-off temperature is exceeded, the solar pump will be
switched off again.
Heat will be extracted from the stores according to the adjusted order. When all
stores have reached their minimum temperature of 5 °C, the function becomes
inactive.
If the function is activated, the pump is run at its maximum relative speed.

The Afterheating suppression blocks the conventional backup heating of a
store that is currently in solar loading.
This function is activated if a previously selected Store is being loaded.
Solar loading means that store loading is only carried out for energy supply and not
for cooling purposes etc.
If the Tset option is activated, the backup heating will only be suppressed when the
store temperature exceeds Tset.
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.
Note:
In systems with east- / west collectors, 2 separate menus will be displayed.

With this function, e. g. a valve can be controlled in parallel to a solar pump via a
separate relay.
Switch-on condition for the solar parallel relay function is that one or more of the
selected stores is being loaded. If at least one of the selected stores is being loaded,
the parallel relay is energised.
The parallel relay function operates regardless whether the store is subjected to
regular solar loading or to a loading caused by an optional function (such as the
collector cooling).
Note:
If a relay is in the manual mode, the selected parallel relay will not be
energised.
Cooling mode
In the Cooling mode menu, different cooling functions are available. They can
be used for keeping the solar system operational for a longer time during strong
solar irradiation.
For this purpose, the adjusted maximum store temperatures can be exceeded. The
store order for this overloading can be adjusted. Additionally, each individual store
can be excluded from this function.
2 different variants are available for the cooling mode: the system cooling and the
collector cooling.
38
System cooling:
If the system cooling variant has been selected and the switch-on temperature difference is exceeded, store loading is continued even if the corresponding maximum
temperature is exceeded, but only up to the emergency shutdown temperature.
Store loading continues until all stores have reached the emergency shutdown
temperature or until the switch-off temperature difference is reached.
Collector cooling:
If the collector cooling variant has been selected, store loading is continued or
reactivated when the collector maximum temperature is exceeded.
Store loading continues until all stores have reached the emergency shutdown
temperature or until the collector temperature falls below the collector maximum
temperature by at least 5 K.
In 2-collector systems, separate adjustments can be made for each collector field.
The control logic regards collector cooling operation as solar loading.The adjusted
values for delay, minimum runtime, etc. remain valid.
Store cooling option:
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.
When the store cooling function is activated, the solar pump is switched on if
the maximum store temperature is exceeded and the collector temperature falls
below the store temperature. The solar pump remains active until the store temperature falls below the adjusted maximum store temperature.
The store order for the cooling is the same as in the overheating through systemor collector cooling.

The Holiday function works like the store cooling function but aims to cool the
store further down during times without DHW consumption in order to prepare
it for solar loading on the following day. This function can only be activated if the
store cooling function is activated.
The holiday function can either be activated manually when a phase with no DHW
consumption begins, or a time frame, during which the function is to become active, can be set in advance. If Manual is selected, an input can be allocated to the
function. When a switch is connected to the allocated input, it will act as an on/off
switch for the holiday function.

In a drainback system, the heat transfer fluid will flow into a holding tank if solar
loading does not take place. The drainback option initiates the filling 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.
en
The filling time can be adjusted using the parameter Filling time. During this
period, the pump runs at 100 % speed.
The parameter Stab. time is used for adjusting the time period during which the
switch-off condition will be ignored after the filling time has ended.
The parameter Initialis. is used for adjusting the time period during which the
switch-off condition will be ignored after the filling time has ended.
The Booster option is used for switching on a second pump when filling the solar
system. The corresponding relay is switched on at 100 % speed for the duration of
the filling time.
A short time (Delay time) after the system has been emptied, the Drain impulse
option will switch on the solar pump for an adjustable Duration. Thus, a hydrostatic head will form in the flow pipe.When it falls back into the holding tank, water
pockets remaining in the collector will be sucked down into the holding tank.

The Twin pump function controls the equal distribution of pump runtime in systems with 2 equally usable pumps.
If the allocated relay has exceeded its adjusted Runtime and the next switch-on
process is imminent, the Reference relay is switched on instead. All characteristics are adopted.
If the reference relay has in turn exceeded its runtime as well, the first relay is
switched on again in the next switch-on process.
Additionally, the Flow rate monitoring option can be activated in order to activate the twin pump in the case of a flow rate error.When the flow rate monitoring
option is activated, 2 additional adjustment channels appear for allocating a sensor
and adjusting a delay time.
If the flow rate monitoring option is activated, an error message will appear when
no flow rate is detected at the allocated sensor after the Delay time has elapsed.
The active relay will be blocked as defective and the second relay will be activated
instead. The twin pump function will pause until the error message has been acknowledged.
When the error message is acknowledged, the controller runs a test during which
it will energise the relay and again monitor the flow rate.
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.
Whether the heat dump is activated via an additional pump or a valve can be adjusted in the menu item Variant.

The Flow rate monitoring function can be used to detect malfunctions that
impede the flow rate and to switch off the corresponding relay. This will prevent
system damage, e. g. through a dry run of the pump.
If the flow rate monitoring function is activated, an error message will appear when
no flow rate is detected at the allocated flowmeter after the delay time has elapsed.
• If a Reference relay has been selected, the flow rate monitoring function will
become active when the allocated relay is switched on. In the case of an error,
the complete solar system will be shut down.
• If both a Store and a Reference relay have been selected, the flow rate monitoring function will become active when the allocated relay is switched on. In
the case of an error, the allocated store will be blocked until the error message
has been acknowledged. The next store free for loading will be loaded instead.
The error message will appear both in the Status / Messages menu and in the
Status / Solar / Flow rate mon. menu. It can be acknowledged in the Status / Solar / Flow rate mon. menu.When the error message is acknowledged, the controller runs a test during which it will energise the relay and again monitor the flow rate.
42
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 On, 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 Off, the
system is switched on again.
8.3
Note:
For the Overpressure monitoring function, On always is at least 0.1
bar higher than Off. The corresponding adjustment ranges will automatically adapt to that.
Note:
For the Low pressure monitoring function,Off always is at least 0.1 bar
higher than On. The corresponding adjustment ranges will automatically
adapt to that.

∆T monitoring
This function is used for monitoring the temperature difference. The message ∆T
too high is shown if solar loading has been carried out for a period of 20 min 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
• hydraulic blockage of a system component
• circulation problems in the collector
• air inside the system
• defective valve / defective pump
43
8.4
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 one of the following conditions has been detected for at least 1 min during
the period between 11 p.m. and 5 a.m.:
• collector temperature exceeds 40 °C
• the temperature difference exceeds ∆Ton
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
en
Flow and return interchanged
This function is used for detecting an interchange of the flow 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. The message
FL / RE interchanged will appear, when 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.
In the Store channel, the store or stores to be monitored can be selected. A
possible cause for an unwanted exceedance of the maximum store temperature
is a defective valve.

The allocated FS08 flow switch is monitored for circuit continuity. If circuit continuity is detected at the flow switch, the relay switches on for the adjusted runtime.
After the runtime has ended, the relay is switched off. During the adjusted break
time, the relay remains switched off even if continuity is detected at the flow switch.
Function block
In addition to the pre-defined optional functions, function blocks consisting of thermostat functions, timer and differential functions are available. With the help of
these function blocks, further components, resp. functions can be controlled.
To each function block, sensors and free relays can be allocated. Sensors already in
use can be allocated again without impeding their control functions.
Within a function block the functions are interconnected (AND gate). This means
that the switching conditions of all the activated functions have to be fulfilled (e. g.
thermostat and timer) for switching the allocated relay. As soon as one condition is
not fulfilled, the relay is switched off.
en
Thermostat function
The switch-on condition for the thermostat function is considered fulfilled when
the adjusted switch-on temperature (Th(x) on) is reached. It is considered unfulfilled when the adjusted switch-off temperature (Th(x)off) is reached.
Allocate the reference sensor in the Sensor channel.
Adjust the maximum temperature limitation with Th(x)off> Th(x)on and the minimum temperature limitation with Th(x)on> Th(x)off. The temperatures cannot be
set to an identical value.
∆T function
The switch-on condition for the ∆T function is considered fulfilled when the adjusted switch-on temperature (∆T(x) on) is reached. It is considered unfulfilled
when the adjusted switch-off temperature (∆T(x)off) is reached.
The ∆T function is equipped with a speed control function. A set temperature difference and a minimum speed can be adjusted. The non-adjustable rise value is 2 K.
Reference relay
Up to 5 reference relays can be selected.
Whether the reference relays are to be switched in series (AND) or in parallel
(OR) can be adjusted in the Mode channel.
In the OR mode, the switch-on condition for the reference relay function is considered fulfilled when at least one of the reference relays is active.
If none of the reference relays is active, the switch-on condition for the reference
relay function is considered unfulfilled.
In the AND mode, the switch-on condition for the reference relay function is considered fulfilled when none of the reference relays is inactive. As soon as at least
one of the reference relays is inactive, the switch-on condition for the reference
relay function is considered unfulfilled.
Note:
If more than one function block has been activated, relays of numerically
higher function blocks may not be used as reference relays.

Relay option
If the Relay option is activated, the sub-menu Relay appears, in which a relay can
be allocated to the demand.
The options Boiler protection min and Boiler protection max can be activated for the demand, allowing temperature-dependent control of the boiler demand. For this purpose, a boiler sensor (Sensor boiler) is required.
The Boiler pr. min option is used for protecting an older type boiler against cooling. If the temperature falls below the adjusted minimum temperature, the allocated
relay is energised until the minimum temperature is exceeded by 2 K.
The Boiler pr. max option is used for protecting an older type boiler against
overheating. If the adjusted maximum temperature is exceeded, the allocated relay
is switched off until the temperature falls by 2 K below the maximum temperature.
Example:
The potential-free relay R5 can be allocated to the demand. R5 will then become
available for potential-free boiler demand in the heating circuits and e. g. the DHW
heating function.
0-10 V option
If the 0-10 V option is activated, the sub-menu 0-10 V will appear, in which a 0-10 V
output can be allocated to the demand.
With this option, the controller can demand modulating heat generators equipped
with a 0-10 V interface.
The characteristic curve of the 0-10 V signal as a function of the boiler set temperature are defined by means of 2 set points according to the specifications of
the boiler manufacturer. At a temperature of Tset 1, the voltage signal of the heat
generator is Volt 1. At a temperature of Tset 2, the voltage signal of the heat
generator is Volt 2.The controller automatically calculates the characteristic curve
resulting from these values.

en
In this menu, up to 2 heating demands can be activated and adjusted.
Activated demands will be available for selection in the output allocation channels of the backup heating in heating circuits and heating optional functions.This way, several heating circuits and optional functions
can demand the same heat source.
Every demand can be carried out by means of a relay and/or a 0-10 V output. If both
the Relay and the 0-10 V option are activated, the demand will use both outputs
in parallel.
Boiler set temperature in °C
Tmax
By means of the adjustment channels Tmax and Tmin the maximum and minimum limitations for the boiler set temperature can be defined.
The value ΔTflow will be automatically added to the boiler set temperature in
order to compensate for e. g. the heat loss in the pipes.
When the Sensor flow option is activated, the controller will monitor whether
the heat generator actually reaches the desired set temperature and will, if necessary, adjust the voltage signal accordingly. In order to do so, the controller will
check the temperature at the boiler flow sensor when the Interval has elapsed. If
the temperature measured deviates from the boiler set temperature by more than
the Hysteresis value, the voltage signal will be adapted by the Correction value.
This process will be repeated until the temperature measured is identical to the
boiler set temperature.
When the Min. runtime option is activated, a Minimum runtime can be adjusted for the demand.
Note:
If the 0-10 V demand is used for DHW heating, the voltage signal will
always be identical to Tmax.

10.2
Heating circuits (with EM Extension Modules only)
Summer mode
The Mode channel adjustment determines how the heating circuit is set to summer mode:
en
The controller is able to control 2 external, weather-compensated heating circuits
by means of extension modules.
If one or more extension modules are connected, they have to be registered with
the controller. Only registered modules are available in the heating circuit selection.
In the menu appearing when new HC… is selected, it is possible to choose between registered modules.
Extension modules can be registered in the In-/Outputs / Modules menu.
If an external heating circuit has been selected, a new menu opens. In this menu, all
sensors and relays required for the heating circuit can be allocated, and all adjustments can be made.
Summer off: The summer mode becomes active when the outdoor temperature
exceeds the adjusted summer temperature TSummer.
Note:
Only relays and sensors of the modules registered are available!
Ext. switch: A switch is connected to a selected sensor input. If the switch is
operated, the heating circuit is set to summer mode regardless of the outdoor
temperature.
The controller calculates the set flow temperature for each heating circuit by
means of the outdoor temperature and the selected heating curve. If the measured
flow temperature deviates from the set flow temperature, the mixer is activated in
order to adjust the flow temperature correspondingly.
If the outdoor temperature falls below the point where the calculated set flow
temperature would exceed the maximum flow temperature, the maximum flow
temperature is treated as the set temperature for as long as the condition remains.
If the outdoor temperature sensor is defective, an error message will be indicated.
For the duration of this condition, the maximum flow temperature -5 K is assumed
as set flow temperature.
With the timer, the day / night operation can be adjusted. During day phases, the set
flow temperature is increased by the adjusted Day correction value, during night
phases it is decreased by the Night correction value (night setback).
Both: As long as the switch is not operated, summer mode control works as
described for Summer off. If the switch is operated, the heating circuit is set to
summer mode regardless of the outdoor temperature.
56
Summer temperature
If Summer off or Both has been selected in the Mode channel, the summer
temperature TSummer can be adjusted. If the outdoor temperature exceeds the
value adjusted in TSummer, the heating circuit pump is switched off.
Heating curves
When the Timer option is activated, a timer is indicated in which time frames for
the function can be adjusted.
Outdoor temperature in °C
For the summer temperature, a daytime time frame can be adjusted with the channels Daytime on and Daytime off. Outside this time frame, the adjustable temperature TNight replaces TSummer.
With the Room thermostat option, up to 5 room thermostats can be integrated
into the control logic.
To each room thermostat, a sensor input can be allocated. The temperature at the
allocated sensor is monitored. If the measured temperature exceeds the adjusted
Room temperature value at all activated room thermostats, the heating circuit
pump is deactivated and the mixer remains in its current position.
Common room thermostats with potential-free outputs can be used alternatively.
In this case, Switch must be selected in the Type channel. Beforehand, the corresponding input must also be set to Switch in the Inputs / Outputs menu. Only
inputs set to Switch will be displayed in the channel Sen. RTH as possible inputs
for a Switch type room thermostats.
If the Timer RTH option is activated, time frames can be set for the room thermostats. During these time frames, the adjusted room temperature is decreased
by the Correction value.
To each room thermostat, an additional relay can be allocated. That relay will operate when the temperature at the allocated sensor falls below the adjusted room
temperature. This way, the room in question can be excluded from the heating
circuit via a valve as long as the desired room temperature is reached.
In the channel RTH, the room thermostat can be temporarily deactivated or re-activated respectively. All adjustments remain stored.
Backup heating mode:
By means of the Mode parameter, the backup heating mode can be selected.
In the Therm. mode, the flow set temperature will be compared to a store reference sensor.
In the Boiler mode, the flow set temperature will be compared to two store
reference sensors. The switching conditions have to be fulfilled at both reference
sensors.
In the On / Off mode, the backup heating will be activated when the heating circuit
pump is switched on.
Chimney sweeper function
The chimney sweeper function can be used for enabling a quick access to measurement conditions without menu operation for the chimney sweeper.
If the chimney sweeper function is activated, the chimney sweeper mode can be
accessed by pressing button ➅ for 5 s.
In the chimney sweeper mode, the heating circuit mixer opens, the heating circuit
pump and the backup heating contact are activated. While the chimney sweeper
mode is active, the directional pad is illuminated. Additionally, Chimney sweeper
and a countdown of 30 min are indicated on the display.
When the countdown has elapsed, the chimney sweeper mode is automatically
deactivated. If, during the countdown, button ➅ is again pressed for more than 10
s, the countdown starts again.
In order to abort the countdown and thus deactivate the chimney sweeper mode,
briefly press button ➅.
Antifreeze option
The antifreeze option of the heating circuit can be used to temporarily activate
an inactive heating circuit during sudden temperature drops in order to protect it
from frost damage.
When the antifreeze option is activated, the temperature at the allocated sensor is
monitored. If the temperature falls below the adjusted Antifreeze temperature,
the heating circuit is activated for the non-adjustable runtime of 30 min. The Antifreeze option operates with a fixed set flow temperature which can be changed in
the Flow set channel.

Description
Factory setting
This function helps to contain the spread of Legionella in DHW stores by systematically activating the backup heating. One sensor and one relay can be selected
for this function. For thermal disinfection, the temperature at the allocated sensor
has to be monitored. 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 backup heating. 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 backup heating 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 h at 18:00 instead
of 12:00 o'clock.

Screed drying
This function is used for time- and temperature-controlled screed drying in selectable heating circuits.
Note:
The screed drying function is blocked against the chimney sweeper function. In order to activate the screed drying function, the chimney sweeper
function must be deactivated in all heating circuits.
At the beginning of the screed drying function, the selected heating circuits are put
into operation for the adjusted rise time with the start temperature as the set
flow temperature. Afterwards, the set flow temperature increases in steps by the
adjustable rise value for the duration of the adjustable rise time until the holding
temperature is reached. After the holding time has elapsed, the set flow temperature is reduced in steps until the start temperature is reached again.
The heating circuits can be selected in the Heating / Screed drying menu. At the
end of this menu, the function can be set to standby by using the “Activated” item.
en
If button ➅ is pressed and held down for at least 5 s, the screed drying programme
will start.
The message Screed drying is indicated on the display and the remaining time
will be indicated as a countdown (dd:hh). During this process, the directional pad
is flashing red.
If the set flow temperature is not reached within 24 hours or after the rise time respectively, or if it is constantly exceeded, the screed drying function will be aborted.
The heating circuit switches off and an error message is displayed. The directional
pad flashes red.
Error 1: flow sensor defective
Error 2: the flow temperature is higher than the set flow temperature + 5 K for over 5 min
Error 3: the flow temperature is higher than the holding temperature + rise value for over
30 min
Error 4: the flow temperature is higher than the set flow temperature + rise value for over 2 h
Error 5: the flow temperature is lower than the set flow temperature - rise value for over a
rise time period
During screed drying of the heating circuits selected, the other heating circuits run

If the Flow rate sensor option is activated, an impulse input or, if available, a
Grundfos Direct Sensor™ can be selected. Grundfos Direct Sensors™ are only
available if they have been previously registered in the In-/Outputs menu. The impulse rate must be adjusted in that menu as well.
If the Flow rate sensor option has been activated and a relay allocated, heat quantity measurement will only take place when the allocated relay is switched on.
If the Flow rate sensor option is deactivated, the controller calculates the heat
quantity by means of a fixed flow rate value (heat quantity balancing). The heat
quantity balancing (estimation) uses the difference between the flow and return
temperatures and the entered flow rate (at 100 % pump speed).
Î Read the flow rate (l / min) and adjust it in the Flow rate channel.
Î Adjust the antifreeze type and concentration of the heat transfer fluid in the

Sensors
The product range includes high-precision platinum temperature sensors, flatscrew
sensors, outdoor temperature sensors, indoor temperature sensors, cylindrical
clip-on sensors, also as complete sensors with immersion sleeve.
SD3 / SDFK Smart Display / GA3 Large Display
The Smart Display is designed for simple connection to controllers with VBus®. It
is used for visualising data issued by the controller: collector temperature, store
temperature and energy yield of the solar thermal system.
The SDFK Smart Display indicates the solid fuel boiler temperature and the bottom / top store temperatures as well as the pump status. The use of high-efficiency
LEDs and filter glass assures a high optical brilliance. An additional power supply
is not required.
The 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 VBus® is possible. The front plate is made of antireflective filterglass
and is printed with a light-resistant UV-lacquering. The universal VBus® allows the
parallel connection of 8 large displays as well as additional VBus® modules.
SP10 Overvoltage protection device
In order to avoid overvoltage damage at collector sensors (e.g. caused by local
lightning storms), we recommend installing the SP10 Overvoltage protection.
CS10 Solar cell
The CS10 Solar cell is used for detecting the irradiation intensity. The short-circuit
current rises with the increase in irradiation intensity. Depending on the controller,
the sensor can also be used for additional plausibility control or direct control.The
connecting cable can be extended by up to 100 m.
VFD and RPD Grundfos Direct Sensors™
The RPD Grundfos Direct Sensor™ is a digital sensor that measures both temperature and pressure. The VFD Grundfos Direct Sensor™ is a digital sensor that
measures both temperature and flow rate.
V40 flowmeter
The V40 is a measuring instrument for detecting the flow of water or water/glycol
mixtures. After a specific 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-defined parameters (glycol type, concentration, heat capacity, etc.).
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.
EM Extension module
The EM Extension module offers 5 additional relay outputs and 6 additional sensor
inputs for the controller.
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 configured 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 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.
