3 Step-by-step parameterisation

The DeltaTherm® HC MAX is a controller that offers a broad variety of func-

tions to the user. At the same time, the user has a lot of freedom in congurating them. Therefore, to set up a complex system, careful planning is required. We recommend drawing a sketch of the system rst.

If planning, hydraulic construction and electrical connection have all been carried out successfully, proceed as follows:

1. Running the commissioning menu

After the commissioning menu has been nished (see page 19), further adjustments can be made. The commissioning menu can be repeated any time by means

of a reset (see page 59). Additional adjustments will be deleted. For further information about the commissioning menu see page page 19.

2. Registering sensors

If owmeters, ow switches, Grundfos Direct Sensors™, a FlowRotor, room control units, remote controls, switches and/or external extension modules are connected, these have to be registered in the Inputs / Modules menu.

For further information about the registration of modules and sensors see page

62.

3. Adjusting heating circuits and activating optional heating functions

If one or more heating circuits are to be controlled, heating circuits can be activated

and adjusted.

For the heating part of the arrangement, up to 16 optional functions can be selected, activated and adjusted.

To heating circuits and optional functions which require one or more relays, the

corresponding number of free relays can be allocated. The controller always sug-

gests the numerically smallest relay available.

Sensors can be allocated to more than one function.

For further information about heating circuits and optional heating functions see

page 36.

4. Activating optional arrangement functions

Up to 16 optional functions can be selected, activated and adjusted in the arrangement part.

Relays available can be allocated to optional functions which require a relay. The controller always suggests the numerically smallest relay available.

Sensors can be allocated to more than one function.

For further information about the optional arrangement functions see page 49.

4.4 Adjusting optional functions

In the Optional functions menus, optional functions can be selected and adjusted. By selecting Add new function, different pre-programmed functions can be se-

lected. The kind and number of optional functions offered depends on the previous ad-

justments.

When a function is selected, a submenu will open in which all adjustments required

can be made.

In this submenu, an output and, if necessary, certain system components can be

allocated to the function.

If an output can be allocated to the function, the output selection menu Output will open (see page 16).

When a function has been adjusted and saved, it will appear in the Opt. functions menu above the menu item Add new function.

This allows an easy overview of functions already saved. An overview about which sensor has been allocated to which component and

which relay has been allocated to which function is given in the Status menu.

At the end of each optional function submenu, the menu items Function and Save function are available. In order to save a function, select Save function and con- rm the security enquiry by selecting Ye s .

In functions already saved, the menu item Delete function will appear instead.

In order to delete a function already saved, select Delete function and conrm

the security enquiry by selecting Ye s . The function will become available under Add new function again. The corresponding outputs will be available again.

With the menu item Function, an optional function already saved can be tem-

porarily deactivated or re-activated respectively. In this case, all adjustments will

remain stored, the allocated outputs will remain occupied and cannot be allocated

to another function. The allocated sensor will be monitored for faults.

By selecting Switch, the function can be activated or deactivated respectively by

means of an external potential-free switch.

The selection is only available if a sensor input has previously been set to Switch in

the Inputs / Modules menu.

If Switch is selected, the channel Sensor will appear. In this channel, the sensor

input to which the switch is to be connected can be allocated to the function.

4.5 Output selection submenu

The Output selection submenu is available in almost all optional functions. Therefore, it will not be explained in the individual function descriptions.

In this submenu, relays and / or signal outputs can be allocated to the function se-

lected. All adjustments required for the outputs can be made in this menu.

All controller and module (if connected) outputs available will be displayed. If - is se- lected, the function will run normally in the software but will not operate an output. Relay and signal outputs can be activated separately. Depending on the adjustments made, the following results are possible:

Detail

Speed control

In the Speed adjustment channel, the speed control for the output can be activated

or deactivated respectively If Yes is selected, the channels Min., Max and Adapter

will appear.

In the Min. adjustment channel, a relative minimum speed for a pump connected

can be allocated to the output

In the Max. adjustment channel, a relative maximum speed for a pump connected

can be allocated to the output.

If the speed control signal is generated via a VBus

/ PWM interface adapter, the

Adapter option has to be activated. If Ye s is selected, the relay will switch on or off

(no burst control). Speed information will be transmitted via the VBus

For functions controlling loads which are not speed controlled, the speed control

will not be shown on the display (e. g. the bypass type, mixer).

If the temperature difference reaches or exceeds the Switch-on temperature differ-

ence, 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 exceeds the adjusted

Set value by 1/10 of the rise value, the pump speed increases by one step (1 %). The

response of the controller can be adapted via the parameter Rise. Each time the

difference increases by 1/10 of the adjustable Rise value, the pump speed increases

by one step until the Maximum pump speed of 100% is reached. If the temperature

difference decreases by 1/10 of the adjustable Rise value, pump speed will be de-

creased by one step.

Relay option If the Relay option is activated, a relay can be allocated to the output selection.

0-10 V option

If the 0-10 V option is activated, a 0-10 V output can be allocated to the output selection.

In the Signal channel, a selection between a PWM or a 0-10 V signal can be made. In the Prole channel, characteristic curves for solar and heating pumps can be selected.

Blocking protection

In order to protect the pumps against blocking after standstill, the controller is equipped with a blocking protection option. This option can be activated in the

output selection submenu. The Blocking protection option can be adjusted in the Basic setting / Blocking protection menu (see page 59).

Manual mode

In the Manual mode adjustment channel, the operating mode of the output can be selected. The following options are available:

Off = Output is switched off (manual mode) Min = Output active at minimum speed (manual mode) Max = Output active at 100 % speed (manual mode) Auto = Output is in automatic mode

Note

After service and maintenance work, the operating mode must be set

back to Auto. Normal operation is not possible in manual mode.

5 Commissioning

When the hydraulic system is lled and ready for operation, connect the controller

to the mains. The controller runs an initialisation phase in which the directional pad glows red. When the controller is commissioned or when it is reset, it will run a commis-

sioning menu after the initialisation phase. The commissioning menu leads the user through the most important adjustment channels needed for operating the system.

5.1 Schemes with basic settings

The controller is pre-programmed for 36 schemes. The basic pre-adjustments have already been made. For backup heating it is necessary to allocate the demand and

the boiler loading pump by means of shared relays. Afterwards the system can easily be extended.

Relay and sensor allocation correspond to the gures. Scheme 0 has no pre-adjustments.

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.

Relay option

If the Relay option is activated, the submenu Relay will appear, in which a relay can

be allocated to the demand.

The options Boiler protection min and Boiler protection max can be activat-

ed for the demand via a relay, allowing temperature-dependent control of the boiler

demand. For this purpose, a Boiler sensor has to be selected.

The Boiler protection min option is used for protecting an older type boiler

against cooling. If the temperature falls below the adjusted minimum temperature,

the allocated relay will be energised until the minimum temperature is exceeded

by 5 K.

The Boiler protection max option is used for protecting an older type boiler

against overheating. If the adjusted Maximum temperature is exceeded, the allocat-

ed relay will be switched off until the temperature falls by 5 K below the maximum

temperature.

Example:

The potential-free relay R14 can be allocated to the shared relay Demand 1. R14

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 submenu 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 set boiler temperature is dened by means of 2 set points according to the specications 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.

Set boiler temperature in °C

Voltage signal in V

By means of the adjustment channels Tmax and Tmin the maximum and mini-

mum values for the set boiler temperature can be dened. When the Sensorow 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 ow 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 set

boiler temperature. When the Min. runtime option is activated, a Minimum runtime can be adjust- ed for the demand.

Note

If the 0-10 V demand is used for DHW heating, the voltage signal will always

be identical to Tmax.

8.2 Heating circuits

The controller has 4 mixed weather-compensated heating circuits and is able to

control up to 3 external mixed 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 will be available in the heating circuit se-

lection. If New HC… is selected for the rst time, the rst heating circuit is allocated to

the controller. In the heating circuit menu, relays for the heating circuit pump and the heating

circuit mixer can be selected.

3 free relays are required for a mixed heating circuit.

If the measured ow temperature deviates from the Set ow temperature, the mixer will be activated in order to adjust the ow temperature correspondingly.

The mixer runtime can be adjusted with the parameter Interval.

Heating system submenu

In the Heating system submenu, a Mode for the heating circuit control can be selected and adjusted. 5 modes are available:

• Constant

• Curve

• Linear

• Room inuence

• Room

The constant mode aims to keep the set ow temperature at a constant value which can be adjusted by means of the parameter Towset.

Set ow temperature = set temperature + remote control + day correction or

night correction

If the Curve mode is selected, the controller will calculate a set ow temperature by means of the outdoor temperature and the Heating curve selected. In both cases, the dial setting of the remote control and the controller Day correction or Night correction will be added.

Set ow temperature = heating curve temperature + remote control + day correction or night correction.

The Remote control allows manual adjustment of the heating curve (± 15 K). Furthermore, the heating circuit can be switched off or a rapid heat-up can be carried

out by means of the remote control. Heating circuit switched off means that the heating circuit pump is switched off and

the mixer closed. The ow temperature is boosted to maximum for rapid heat-up

when the remote control is set to rapid heat-up.

The calculated set ow temperature is limited by the adjusted values of the param-

eters maximumowtemperature and minimumowtemperature.

Maximum ow temperature ≥ set ow temperature ≥ minimum ow temperature

If the outdoor temperature sensor is defective, an error message will be indicated.

For the duration of this condition, the maximum ow temperature -5 K is assumed

as the set ow temperature in the Curve and Linear mode.

In the Linear mode the ow temperature curve will be calculated depending on

the outdoor temperature by 2 points. At a temperature of TOutdoor 1 the set

ow temperature is TFlow 1. At a temperature of TOutdoor 2 the set ow

temperature is TFlow 2. The controller automatically calculates the characteristic

curve resulting from these values.

By means of the adjustment channels Towmax and Towmin the maximum and

minimum values for the set ow temperature can be dened.

In the Room inuence mode, the weather-compensated set ow temperature

will be expanded by a demand-based room control. The parameter Room factor

can be used for determining the intensity of the room inuence.

The controller will calculate the set ow temperature using the heating system

Curve plus the room inuence: Set ow temperature = set temperature + remote

control + day correction or night correction + room inuence.

In order to calculate the deviation of the room temperature from the adjusted set

value, at least one sensor-type room thermostat is required. The adjustments can be

made in the Room thermostats submenu, Room therm. (1 ... 5).

The parameters Day- / Night correction and Timer will not be indicated.

The start value of the set ow temperature can be inuenced by the parameter

TStart.

In order to calculate the deviation of the room temperature from the adjusted set value, a room thermostat is required. The adjustments can be made using the

parameter RTH(1 … 5) . For this purpose, select Sensor in the Type adjustment channel.

The adjustments of all activated room thermostats will be taken into account. The controller will calculate the average value of the deviations measured and correct the set ow temperature correspondingly.

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

Set room temperature at all activated room thermostats and if the parameter HC off is activated, the heating circuit will switch off.

Common room thermostats with potential-free outputs can be used alternatively. In this case, Switch must be selected in the Type channel. The corresponding input

must beforehand be set to Switch in the Inputs / Modules menu. Only inputs set to switch will be displayed in the channel Sensor RTH as possible inputs for a switch type room thermostat.

When the Timer option is activated, a timer is indicated in which time frames for the function can be adjusted. Outside these time frames, the adjusted room temperature is decreased by the Correction value. If the Special operation Cooling is active, the set room temperature will increase by the Correction value.

Note

For information on timer adjustment see page 12.

To each room thermostat, an additional relay can be allocated. The relay will switch on when the temperature 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.

With the parameter RTH, the room thermostat can be temporarily deactivated or

re-activated respectively. All adjustments remain stored.

Correction timer

With the Timer, the day / night operation can be adjusted. During day phases, the set ow temperature is increased by the adjusted day correction value, during

night phases it is decreased by the night correction value (night setback).

The parameter Mode is used for selecting between the following correction modes:

Day / Night: A reduced set ow temperature (night correction) is used during

Night operation.

Day / Off: The heating circuit and the optionally activated backup heating are

switched off during night operation.

The Timer HC can be used for adjusting the time frames for day operation.

Summer operation

For summer operation, 2 different modes are available:

Day: If the outdoor temperature exceeds the Summer temperature day, the

heating circuit will switch off.

Day / Night: The parameters Daytime on and Daytime off can be used for

adjusting a time frame for the summer operation. If the outdoor temperature ex-

ceeds the Summer temperature day within the adjusted time frame, the heating

circuit will switch off.

Outside the adjusted time frame the Summer temperature night is valid.

Remote access With the parameter Remote access different types of remote access to the con-

troller can be activated.

Note

In the sensor selection menu, only outputs which have previously been

selected as the input for remote access in the Inputs / Modules menu

will be available.

The following types of remote access are possible:

Remote control: A device which allows manual adjustment of the heating curve, thus inuencing the set ow temperature.

Î In order to use a remote control, set the Mode to Fern.

Room control unit: A device incorporating a remote control as well as an addi-

tional operating mode switch.

Î In order to use a room control unit, set the Mode to BAS.

The operating mode switch of the room control unit is used for adjusting the oper-

ating mode of the controller. If a room control unit is used, the operating mode can

be adjusted by means of the room control unit only. The controller menu will only

allow the activation of the operating mode Holiday.

App: An app can be used for remote access.

Î In order to use an app, set the Mode to App.

If you use an app, the operating mode can be adjusted in the controller menu as

well as in the app.

Backup heating

For the Backup heating of the heating circuit, 3 modes are available:

In the Therm. mode, the set ow temperature will be compared to a store ref- erence sensor.

In the Zone mode, the set ow temperature will be compared to 2 store reference

sensors. The switching conditions have to be fullled at both reference sensors.

In the On / Off mode, the backup heating will be activated when the heating circuit pump is switched on for heating.

In the Demand submenu, the modes standard and Demand are available. If

Standard is selected, the output can be adjusted.

If Demand is selected, a demand has to be activated and adjusted in the Heating / Shared relays menu rst. If Adjustment values is selected, the Heating / Shared relays / Demand menu will open.

In the correction mode Day / off (see page 39) the heating circuit and the backup heating will be completely switched off during the night operation. The Starting

optimisation option can be used for activating the backup heating before the day operation in order to heat the store to a sufciently high temperature. The Stop- ping optimisation option can be used for deactivating the backup heating before

the start of the night operation.

If SFB off is activated, backup heating will be suppressed when a selected solid fuel

boiler is active.

At rst, backup heating is activated and can be temporarily deactivated.

DHW priority

If the parameter DHW priority is activated, the heating circuit will be switched off

and the backup heating be suppressed as long as DHW heating takes place which

has previously been activated in the Heating / Optional functions menu.

Chimney sweeper function

The chimney sweeper function can be used for enabling a quick access to measure-

ment conditions without menu operation for the chimney sweeper.

The chimney sweeper function is activated in all heating circuits by default. The

chimney sweeper mode can be activated 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 ashing red. 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 5 s,

the chimney sweeper mode will stop.

Antifreeze function

The antifreeze function of the heating circuit can be used to temporarily activate

an inactive heating circuit during sudden temperature drop in order to protect it

against frost damage.

The temperature at the sensor selected will be monitored. If the temperature falls

below the adjusted antifreeze temperature, the heating circuit will be activated until

the antifreeze temperature is exceeded by 2 K, but at least for 30 min.

Special operation

For the Special operation option, 2 variants are available:

• Cooling

• Heat dump

The Cooling variant is used for cooling via the heating circuit. 3 modes are available:

• Outdoor

• External switch

• Both

In the Outdoor mode, cooling will be activated if the outdoor temperature cooling is exceeded.

In the External switch mode, cooling will be activated by means of an external switch.

In the both mode, both switching conditions are valid for cooling. In the Cooling system submenu, the cooling logic can be adjusted. For the cooling

logic, 2 modes are available:

• Linear

• Constant

In the Linear mode, the set ow temperature will be calculated as in the heating system mode Linear.

The Constant mode aims to keep the set ow temperature at a constant value which can be adjusted by means of the parameter TFlow.

If the Timer option is activated, a time frame can be adjusted in which the cooling

will be active.

If the Dew point switch option is activated, an output can be allocated to the dew point switch. If the dew point switch detects condensation, cooling will be interrupted.

The Heat dump variant is used for diverting excess heat to the heating circuit in

order to keep the system temperatures within the operating range. For this purpose, the temperature measured at the allocated sensor Sensor will be monitored.

If the temperature at the allocated sensor exceeds the Switch-on temperature, the Setowtemperature will be controlled to reach the adjusted value. If the temperature at the allocated sensor falls below the adjusted Switch-off temper-

ature, the heat dump function will switch off.

Energy saving operation

The Energy saving operation is used for optimising the energy consumption of

the heating circuit pump. For this purpose an additional sensor in the heating circuit

return is required. The controller monitors the temperature difference between the

ow and the return of the heating circuit. If the temperature difference falls below

the Switch-off difference, the controller will deactivate the heating circuit pump for the adjusted Break time. After the break time has elapsed, the pump will be

activated for the Runtime. If the temperature difference is higher than the switch- off difference, the pump will remain active. If the temperature difference is below the switch-off difference, the break time will start again.

8.3 Optional functions

In this menu, optional functions can be selected and adjusted for the heating part

of the arrangement. The kind and number of optional functions offered depends on the previous ad-

justments.

Note

For further information about adjusting optional functions, see page 14.

In the Demand submenu, the modes standard and Demand are available. If Standard is selected, the output can be adjusted. If Demand is selected, a demand has to be activated and adjusted in the Heating/ Shared rel. rst. If Adjustment values is selected, the Heating/ Shared rel. / Demand will open.

Note

For information on the output selection see page 16.

Thermal disinfection

This function helps to contain the spread of Legionella in DHW stores by system-

atically activating the backup heating.

One Sensor and one output or Demand respectively can be selected for this function.

For thermal disinfection, the temperature at the allocated sensor has to be monitored. Protection is ensured when, during the Monitoring period, the disinfec-

tion 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. If the monitoring period ends, the Demand will activate the backup heating. The Disinfection period starts when 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. The parameter Cancellation is used for adjusting the period after which the

non-completed backup heating will be cancelled. If the backup heating is cancelled,

an error message will be displayed.

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 hours at 18:00 instead of 12:00 o'clock.

DHW heating

The DHW heating is used for demanding a backup heating for heating the DHW store.

If the Pump / valve option is activated, another adjustment channel appears, in which an Output can be allocated to the Pump / valve. The allocated output will switch on and off with the demand relay.

If the Overrun time option is activated, another adjustment channel appears, in which the overrun time can be adjusted. If the overrun time option is activated, the loading pump relay will remain switched on for the adjusted duration after the demand relay has been switched off.

For the DHW heating, 2 modes are available:

Thermal mode

The allocated demand relay will be switched on when the temperature at the allocated Sensor 1 falls below the adjusted switch-on temperature. If the temperature

at the allocated sensor 1 exceeds the adjusted switch-off temperature, the relay

will be switched off.

Zone mode

If the zone mode has been selected, another sensor can be allocated in the channel Sensor 2. The switch-on, or the switch-off conditions respectively, then have to be fullled at both sensors in order for the output to be switched on or off.

When the Timer option is activated, a timer is indicated in which time frames for the function can be adjusted.

If SFB off is activated,DHW heating will be suppressed when a selected solid fuel

boiler is active.

With the Manual heating option, DHW heating can be activated outside the adjusted time frame once by means of a switch, if the temperature has fallen below the switch-off value.

Note

For information on timer adjustment see page 12.

With the BAS off option, DHW heating can be switched from automatic mode to off by means of the operating mode switch.

DHW preheating

The DHW preheating function uses heat from a buffer store to heat the cold water inlet of the DHW store.

The controller monitors the ow rate at the selected Flow rate sensor. If a ow rate is detected, the pump will switch on with the Starting speed.

If the temperature at the Temperature sensor selected exceeds the adjusted DHW maximum temperature, the speed will be decreased by the Increment

value. The interval to the next measurement and adaptation can be adjusted by

means of the parameter Delay.

If the DHW maximum temperature is not reached after the delay time has elapsed, the speed will be increased by the increment value. The speed will not be increased or decreased respectively within the Hysteresis.

If the

DT function is activated, the pump will switch on only if DTo n is exceeded,

and switch off if the temperature difference falls below DToff. If the Valve option is activated, the output selected will be activated when the

pump is activated.

8.4 Screed drying

This function is used for time- and temperature-controlled screed drying in selectable heating circuits.

The heating circuits can be selected in the Heating / Screed drying menu At the end of this menu, the function can triggered by using Start.

The controller will automatically change to the screed drying status menu. The current Phase will be indicated on the display and the Remaining time will be

indicated as a countdown (dd:hh). During this process, the directional pad is ashing

green.

At the end of the menu, Cancel will be indicated instead of start. If Cancel is selected, screed drying will be cancelled immediately. For this reason, a security enquiry will appear. If you wish to cancel the screed drying function, conrm the

security enquiry.

At the beginning of the screed drying function, the heating circuits selected are put

into operation for the adjusted rise time with the Start temperature as the set

ow temperature. Afterwards, the set ow 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 ow tempera-

ture is reduced in steps until the start temperature is reached again.

If the set ow 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 can-

celled. The heating circuit switches off and an error message is displayed. The directional pad glows red.

Error 1: ow sensor defective

Error 2: the ow temperature is higher than the maximum ow temperature + 5 K

for over 5 min

Error 3: the ow temperature is higher than the holding temperature + rise value for

over 30 min

Error 4: the ow temperature is higher than the set ow temperature + rise value

for over 2 h

Error 5: the ow temperature is lower than the set ow temperature - rise value for

over a rise time period

During screed drying of the heating circuits selected, the other heating circuits run

corresponding to their operating modes. Button ➆ can be used any time for changing to the status or main menu of the

controller in order to carry out adjustments. When the screed drying function has been successfully completed, the correspond-

ing heating circuits will change to their operating modes selected.

Screed drying will automatically be deactivated. The chimney sweeper function will be activated in all heating circuits.

Note Make sure the heating circuits are supplied with heat from a heat source

(backup heating).

Note

If an SD card has been inserted into the slot, a screed protocol will be

generated.

Output

Mixer sensor

The Solid fuel boiler function can be used for transferring heat from a solid fuel boiler to a store.

The allocated output is energised when all switch-on conditions are fullled:

• the temperature difference between the allocated sensors has exceeded the

switch-on temperature difference

• the temperature difference between the allocated sensors has not fallen below the switch-off temperature difference

• the temperature at the solid fuel boiler sensor has exceeded the minimum temperature

• the temperature at the store sensor is below the maximum temperature

• one of the adjusted time frames is active (if the Timer option is selected)

When the Set temperature difference is exceeded, pump speed control starts. For every deviation by 1 / 10 of the adjusted rise value, the pump speed will be

adjusted by 1 %. If the Target temperature option is activated, the pump speed control logic will

change. The controller will remain at the minimum pump speed until the temperature at the allocated Sensor exceeds the adjusted Target temperature.

The Mixer option can be used to keep the boiler return temperature above Tmin boiler. The mixer will be controlled with the adjustable Interval.

In addition to the pre-dened optional functions, function blocks consisting of thermostat functions, timer, differential and reference output functions are available. With the help of these function blocks, further components and functions respectively can be controlled.

To each function block, sensors and outputs available 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 fullled for switching the allocated output. As soon as one condition is not fullled, the output

will switch off.

Thermostat function

The switching condition for the thermostat function is considered fullled when the adjusted switch-on temperature (Th(x) on) is reached.

The switching condition for the thermostat function is considered unfullled 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.

DT function

The switching condition for the DT function is considered fullled when the adjust- ed switch-on temperature (DTon) is reached.

The switching condition for the DT function is considered unfullled when the adjusted switch-off temperature (DToff) is reached.

The DT function is equipped with a speed control function. A set temperature dif-

ference and a minimum speed can be adjusted. The non-adjustable rise value is 2 K.

Reference output

Up to 5 Reference outputs can be selected. Whether the reference outputs are to

be switched in series (AND), in parallel (OR), in series + inverted (NAND) or in parallel + inverted (NOR) can be adjusted in the Mode channel.

OR mode

If at least one of the reference outputs is switched on, the switching condition for the reference output function is considered fullled.

If none of the reference outputs is switched on, the switching condition for the reference output function is considered unfullled.

NOR mode

If none of the reference outputs is switched on, the switching condition for the reference output function is considered fullled.

If at least one of the reference outputs is switched on, the switching condition for the reference output function is considered unfullled.

AND mode

If all reference outputs are switched on, the switching condition for the reference output function is considered fullled.

If at least one of the reference outputs is switched off, the switching condition for the reference output function is considered unfullled.

NAND mode

If at least one of the reference outputs is switched off, the switching condition for the reference output function is considered fullled.

If all reference outputs are switched on, the switching condition for the reference output function is considered unfullled.

Note

If more than one function block has been activated, outputs of numerically

higher function blocks may not be used as reference outputs.

The Return mixing function can be used for heating backup. Heat from the store is mixed into the heating circuit return by means of a mixing

valve in order to add heat to the heating circuit. The controller compares the temperature in the centre of the store to the heating circuit return temperature. If the store temperature exceeds the heating circuit return temperature by the Switch-

on temperature difference, the mixer will be used to add heat from the store to

the heating circuit return. The mixer will be opened or closed in pulses depending

on this deviation. The mixer will be controlled with the adjustable Interval. The pause is determined by the difference between the actual value and the set value.

Thus, the heating circuit return temperature is increased by the DTset value. The

adjustable Maximum boiler return temperature limits the mixing temperature. If the store temperature falls below the heating circuit return temperature by the Switch-off temperature difference, the mixer will close.

If the mixing temperature exceeds Tmax by more than 5 K, a message will appear in the status menu.

The Runtime denes the time needed for the mixer to switch from its initial posi- tion to the end position. The Time denes the point in time when the mixer is set

to its initial or ending position respectively.

HC internal option If the HC internal option is activated, the return mixing function will only become

active when a selectable heating circuit connected to the same controller is active, too. For this purpose, the heating circuit selected has to be controlled by the con-

troller or by a module connected.

10 HQM

In the HQM menu, up to 7 internal heat quantity measurements can be activated and adjusted.

By selecting the menu item new HQM..., a new heat quantity measurement can

be activated.

A menu will open in which all adjustments required for the heat quantity measurement can be made.

If the Flow rate sensor option is activated, an impulse input or, if available, a

Grundfos Direct Sensor™ or a FlowRotor can be selected. The FlowRotor and the Grundfos Direct Sensors™ will only be available if they have been previously

registered in the Inputs / Modules menu. The impulse rate must be adjusted in that menu as well.

If the Flow rate sensor option is deactivated, the controller calculates the heat

quantity by means of a xed ow rate value.This is called heat quantity balancing. For this purpose, the ow rate must be read from the owmeter at 100 % pump

speed and adjusted in the adjustment channel Flow rate. In addition to that, a Relay must be allocated. Heat quantity balancing is in effect whenever the allocated

relay is active. In the adjustment channel Fluid type, the heat transfer uid must be selected.

If either Propylene glycol or Ethylene glycol is selected, the adjustment channel Concentration is indicated in which the antifreeze ratio of the heat transfer uid

can be adjusted.

If a calorimeter is being congured for the rst time or after the overall quantity has been reset, the parameter Carryover will appear. A former value which is to be added to the overall quantity, can be entered.

When the Alternative unit option is activated, the controller will convert the heat quantity into the quantity of fossil fuels (coal, oil or gas) saved, or the CO

emission saved respectively. The alternative Unit can be selected. A Conversion factor must be adjusted for the calculation. The conversion factor depends on the

arrangement in use and has to be determined individually.

Heat quantity measurements already saved will appear in the HQM menu above the

menu item new HQM… in numerical order.

If a heat quantity measurement already saved is selected, the above mentioned submenu with all adjustment values will re-open.

At the end of each HQM submenu, the menu items Function and Save function are available. In order to save a heat quantity measurement, select Save function and conrm

the security enquiry by selecting Ye s . In heat quantity measurements already saved, the menu item Delete function will appear instead.

In order to delete a heat quantity measurement already saved, select Delete function and conrm the security enquiry by selecting Ye s . The heat quantity measure- ment deleted will disappear from the list and become available for selection in the

new HQM… menu again.

With the menu item Function, a heat quantity measurement already saved can be temporarily deactivated or re-activated respectively. In this case, all adjustments will

remain stored. By selecting Switch, the heat quantity measurement can be activated or deacti-

vated respectively by means of an external switch. If Switch is selected, the channel Sensor will appear. In this channel, the sensor input to which the switch is to be

connected can be allocated to the function.

Short circuit or line break. Disconnected temperature sensors can be checked with an ohmmeter. Please

check if the resistance values correspond with the table.

If a malfunction occurs, a message will appear on the display of the controller.

WARNING!

Electric shock!

Upon opening the housing, live parts are exposed!

Î Always disconnect the device from power supply be-

fore opening the housing!

The controller is protected by a fuse. The fuse holder (which also holds the spare fuse) becomes accessible when the cover is removed. To replace the fuse, pull the

fuse holder from the base.

16 Troubleshooting

Fuse

Is the pump current enabled by

the controller?

Display illuminated?

If not, press button ➄. Display illuminated again?

Does the pump start up in manual

operation?

The heating circuit pump does not work, although this is indicated on the

status display.

yes no

yes

There is no current; check fuses / replace them and check power supply.

The adjusted temperature difference for starting the pump is too

high; choose a value which makes

more sense.

yesno

Stores cool down at night.

Sufcient store insulation?

yes no

Increase insulation.

Insulation close enough to the store?

yes no

Replace insulation or increase it.

Are the store connections insulated?

yes no

Insulate the connections.

Warm water outow upwards?

no yes

Change connection and let the water

ow sidewards or through a siphon (downwards); less store losses now?

no yes

o.k.

Controller might be defective -

replace it.

Is the pump stuck?

Turn the pump shaft using a

screwdriver; now passable?

Pump is defective - replace it.

yes

Does the DHW circulation run

for a very long time?

no yes

Use the circulation pump with

timer and switch-off thermostat

(energy-efcient circulation).

Circulation pump and blocking

valve should be switched off for 1

night; less store losses?

yes no

Check whether the pumps of the

after-heating circuit run at night;

check whether the non-return

valve is defective; problem solved?

Check the non-return valve in

warm water circulation - o.k.

yes no

The gravitation circulation in the

circulation line is too strong; insert

a stronger valve in the non-return valve or an electrical 2-port valve

behind the circulation pump; the

2-port valve is open when the pump is activated, otherwise it is closed;

connect pump and 2-port valve electrically in parallel; activate the circulation again. Deactivate pump speed control!

Clean or replace it.

Further pumps which are con-

nected to the store must also be

checked.
