6 The settings in detail

6.1 Time programs

For the heating circuits and DHW heating, a number of switching programs are available. They are activated in Automatic mode and control the change of temperature levels (and the respective setpoints) via the set switching times.

Entering the switching times The switching times can be combined, i.e. either in common for several days or in the form of separate times for individual days. The preselection of groups of days like for instance Mo...Fr and Sa-Su that use the same switching times simplifies setting of the switching programs.

Heating curve

	Line no.		Operating line
HC1	HC2	HC3
720	1020	1320	Heating curve slope
721	1021	1321	Heating curve displacement
726	1026	1326	Heating curve adaption

The heating curve generates the flow temperature setpoint, which is used to maintain a certain flow temperature depending on the prevailing weather conditions.

The heating curve can be adjusted with a number of settings, thus matching heat output and room temperature to individual needs.

Heating curve slope As the heating curve slope is raised, the flow temperature increases the quicker the lower the outside temperature or, in other words, if the room temperature is not correct at low outside temperatures but correct at higher outside temperatures, the heating curve slope requires readiustment.

ncreasing the setting:	Raises the flow temperature, especially when outside temperatures are low.
Decreasing the setting:	Lowers the flow temperature, especially when outside temperatures are low.

The set heating curve is based on a room temperature setpoint of 20 °C. If the room temperature setpoint is adjusted, the heating curve adapts automatically to the new value.

Heating curve displacement

Parallel displacement of the heating curve is used to change the flow temperature evenly across the entire outside temperature range or, in other words, if the room temperature is always too high or too low, a readjustment must be made via parallel displacement.

Heating curve adaption

With this function the controller automatically adapts the heating curve to prevailing conditions.

i To assure this function, following must be observed:

A room sensor must be connected.
"Room influence" must be set to a value between 1 and 99.
There should be no thermostatic radiator valves in the reference room (mounting location of room temperature sensor) (if such valves are present, they must be set to their fully open position).

Summer/winter heating limit

The summer / winter heating limit is used to switch the heating on and off in the course of the year, depending on temperature conditions. In Automatic mode, switching on / off takes place automatically, so there is no need for the user to do this manually. By changing the setting, the respective periods of time will be shortened or extended.

Increase:	Winter operation will start earlier Summer operation will start later.
Decrease:	Winter operation will start later Summer operation will start earlier .

24-hour heating limit.

The 24-hour heating limit is used to switch the heating on and off in the course of the day, depending on the outside temperature. This function is used primarily during intermediate seasons (spring and autumn) to respond to short-time temperature variations.

Example:

Operating line	E.g.
Comfort setpoint (TRw)	22 °C
24-hour heating limit (THG)	-3 °C
Changeover temperature (TRw – THG) heating off	=19 °C

Switching differential (fixed	-1 °C
Changeover temperature	heating on	=18 °C

A change in value shortens or extends the corresponding heating phases.

Increase:	Heating mode will start earlier,
	changeover to ECO later.
Decrease:	Heating mode will start later,
	changeover to ECO earlier.

The function is not active in operating mode "Continuously Comfort temperature"
- The display shows ECO.
- To give consideration to the building's thermal dynamics, the outside temperature is attenuated

Page 57

Extension: 24-hour heating limit

The "24-hour heating limit" function (line 732) switches the heating system off when the actual outside temperature has risen to a level of one adjusted differential below the current operating level. Setting an "extended 24-hour heating limit" defines when to turn on heating again.

Extension 24-hour heating limit = No

The heating is switched on again when the present actual outside temperature (TA) drops again below the adjusted differential minus 1 K. The building dynamics (building structure and insulation) are not taken into consideration.

Extension 24-hour heating limit = Yes

The heating is switched on again when the mixed actual outside temperature (TAgem) drops again below the adjusted differential minus 1 K. The building dynamics (building structure and insulation) are taken into consideration.

This limitation can be used to select a range for the flow temperature setpoint. If the flow temperature setpoint demanded by the heating circuit reaches the relevant limit and the heat request increases or decreases, the flow temperature setpoint will be maintained at the maximum or minimum limit.

TVw Current flow temperature setpoint TVmax Flow temp setpoint max TVmin Flow temp setpoint min

Flow temperature setpoint: Room thermostat

On applications with room thermostat, the heating circuit is switched on only when the room thermostat calls for heat.

A fixed or weather-compensated temperature value is called for, depending on the selected setting:

Selection	Compensation variant
	Temperature request according to the heating curve
895 °C	Temperature request according to the set value*
* In Constant made and

In Comfort mode only –

outside the Comfort there is no temperature demand and the heating curve remains switched off

The room thermostat can be connected via an Hx input (H1, H2 (module 1-3), H3) to the controller or an extension module.

	* Outside sensor requir	ed.
Weather compensation alone	The flow temperature is calculated via the heating curve, depending on the composite outside temperature.
Weather compensation alone	This compensatic because with this temperature.	on variant calls for a correct adjustment of the heating curve setting the control system gives no consideration to the room
Weather compensation with room influence	The deviation of t taken into accoun considered, ensuing the second seco	he current room temperature from the setpoint is acquired and it when controlling the room temperature. Heat gains can thus be ring more accurate room temperature control.
	The authority of the deviation is set as a percentage value. The better the reference room (correct room temperature, correct mounting location, etc.) the higher the value can be set.
	Example:
	Approx. 60%	Good reference room
	Approx. 20 %	Unfavorable reference room
i	To provide the fur	nction, following must be considered:
	• A room sensor must be connected
	Room influence" must be set to a value between 1 and 99 %
	There should be no thermostatic radiator valves in the reference room (mo location of room temperature sensor) (if such valves are present, they mus set to their fully open position).
Pure room compensation	The flow temperature is controlled depending on the room temperature setpoint, the current room temperature and the progression of room temperature.
	For example, a slight increase in room temperature leads to an immediate reduction in flow temperature.
i	To provide the fur	nction, following must be considered:
	A room sensor	must be connected.
	"Room influence	e" must be set to 100%.
	There should b location of the	d be no thermostatic radiator valves in the reference room (mounting he room sensor). (If such valves are present, they must be set to

HC1	HC2	HC3
760	1060	1360	Room temp limitation

The "Room temperature limitation" function enables the heating circuit pump to be deactivated if the room temperature exceeds the current room temperature setpoint by more than the adjusted differential.

The heating circuit pump is activated again as soon as the room temperature returns to a level below the current room temperature setpoint.

During the time the "Room temperature limitation" function is active, no heat request is sent to the heat source.

Room temperature limitation does not function with pure weather compensation.

Boost heating

	Line no.		Operating line
HC1	HC2	HC3
770	1070	1370	Boost heating

Boost heating is used to reach the new setpoint more quickly when switching from the Reduced setpoint to the Comfort setpoint, thus shortening the heating up time.

During boost heating, the room temperature setpoint is raised by the value set here.

A higher setting leads to shorter heating up times, a lower setting to longer heating up times.

Boost heating can be provided with or without room sensor.

During quick setback, the heating circuit pump is deactivated and, in the case of mixing circuits, the mixing valve is fully closed.

Function with room When using a room temperature sensor, the function keeps the heating switched sensor off until the room temperature has dropped to the level of the reduced setpoint or the frost level. When the room temperature has fallen to the reduced level or the frost level, the heating circuit nump will be activated and the mixing valve will be released

Function without room Quick setback switches the heating and building time constant off for a certain sensor period dependent on the outside temperature.

Heating up gradient

The heating up gradient defines the period required to increase the room temperature by 1°C.

If the room temperature does not reach the "Comfort" setpoint at the respective switching times, the setting must be increased.

The heating up gradient is only effective when optimum start up is active.

The function is used primarily on heating systems with only little spare capacity (e.g. low-energy houses). In such cases, the heating up time at low outside temperatures would be too long. When the Reduced setpoint is raised, the rooms are prevented from cooling down to too low levels, thus shortening the heating up time when changing to the Comfort setpoint.

In the case of heating plants with pump heating circuits, the flow temperature of the heating circuit can be higher than the flow temperature called for by the heating curve, the reason being higher requests from other heat consumers (mixing heating circuit, DHW charging, external heat demand), or a parameterized minimum heat pump temperature. As a result of this too high flow temperature, the pump heating circuit would assume excessive temperatures.

Function "Overtemperature protection for pump heating circuits" ensures that the energy supply for pump heating circuits corresponds to the demand from the heating curve by activating / deactivating the pump.

The function is automatically ended after 25 days Floor curing setp The flow temperature setpoint for the "Manual floor curing" function can be set manually separately for each heating circuit. Â First, start the "Floor curing" function, then adjust the setpoint manually. The start value is 25 °C and can be manually readjusted at any time. Floor curing setp manually (TVFm) can only be adjusted within the 2 limit values Flow temperature setpoint maximum (TVMax) and Flow temperature setpoint minimum (TVmin). The function ends after the function days (Fh+Bh = 25 days) expire or the function is switched off via the parameter start day (day 0) which is not counted as a functional day. Attic day present Displays the current day and the current setpoint of the "Floor curing" function in Present setpoint for attic progress.

Page 66

Floor curing days completed

The completed number of days are continuously stored and retained until the function is started the next time.

The temperature is regarded maintained if the deviation from the setpoint is less than 2 Kelvin. The periods of time the flow temperature is correct are added up by a meter.

If the required temperature is not reached after more than 1 hour, the meter is stopped until the deviation is again smaller than 2 K.

After a power failure, the plant resumes the floor curing function at the point in time the power failure occurred.

Temperature profile In Automatic modes, the controller ensures automatic completion of the selected temperature profile.

The temperature change is always made at midnight. The start day (day 0), that is, the period of time from activation to midnight does not count as a functional day. The setpoint used for the start day is the value of the first functional day.

During "Floor curing mode", the profile temperature is limited within the 2 limit values Flow temperature setpoint maximum (TVMax) and Flow temperature setpoint minimum (TVmin).

The function is ended when the functional days have elapsed or when the function is deactivated via the respective parameter.

6.4 Cooling circuit

To be able to operate the cooling circuit, an appropriate partial diagram "Heating / cooling" must be used.

The system starts to operate in cooling mode when the room temperature rises above the Comfort cooling setpoint (902). The cooling function must be activated (901 = Auto) and enabled in accordance with the time program (907).

Furthermore, the criteria "Cooling limit at OT" (operating line 912) and "Lock time at end of heating" (operating line 913) must be met.

Cooling mode is cancelled in a 2-pipe system (with active cooling) when a consumer requires heat.

It is possible to charge DHW and heat (using another heating circuit) a heating circuit during cooling mode with a 4-pipe system.

Weather compensation alone

The flow temperature is calculated based on the cooling curve, depending on the composite outside temperature.

This compensation variant demands a correct adjustment of the cooling curve since in that case the control gives no consideration to the room temperature.

Page 74

Weather compensation The deviation of the current room temperature from the setpoint is acquired and with room influence taken into account when controlling the room temperature. This way, consideration is given to room temperature deviations, ensuring more accurate room temperature control. The authority of the deviation is set as a percentage value. The better the reference room conditions (correct room temperature, correct mounting location, etc.), the higher the value can be set Example Approx. 60% Good reference room Approx. 20 % Unfavorable reference room i To provide the function, following must be considered: Room temperature sensor must be connected • "Room influence" must be set to a value between 1 and 99. • There should be no controlled valves in the reference room (mounting location of the room sensor) (If such valves are installed, they must be set to their fully open position) The flow temperature is controlled depending on the room temperature setpoint, Pure room compensation the current room temperature and the progression of room temperature. For example, a slight increase in room temperature leads to an immediate reduction in flow temperature. i To provide the function following must be considered: Room temperature sensor must be connected • "Room influence" must be set to 100% • There should be no thermostatic radiator valves in the reference room (mounting location of room sensor); if such valves are installed, they must be fully opened. Room temperature limitation The room temperature limitation function makes it possible to disable the cooling circuit pump if the room temperature falls by more than the programmed offset from the effective room setpoint (with summer compensation, operating line 920). The heating circuit pump will be activated again as soon as the room temperature returns to a level below the current room temperature setpoint. While the "Room temperature limitation" function is active no cooling request is sent to the heat source

The function is deactivated in the following situations:

DHW heating makes use of time program 4 of the local controller. The set switching times of that program are used to switch between the nominal DHW setpoint and the reduced DHW setpoint. This way, the DHW storage tank is charged independently of the heating circuits.

Example

Priority

Line no. Operating line 1630 Charging priority Absolute | Shifting | None | MC shifting, PC absolute

When both space heating and DHW heating demand heat, the "DHW priority" function ensures that during DHW charging the boiler's capacity is used primarily for DHW.

Absolute priority

Mixing and pump heating circuits are locked until the DHW reaches the required temperature level.

Shifting priority

If the heat source is no longer able to meet the demand, the mixing and pump heating circuits are restricted until the DHW reaches the required temperature level.

No priority

DHW charging occurs in parallel to heating mode. In the case of tightly sized boilers and mixing heating circuits, it can occur that the DHW setpoint will not be reached if space heating demands considerable amounts of heat.

Mixing heating circuit shifting, pump heating circuit absolute

The pump heating circuits remain locked until the DHW storage tank is heated up. If the heat source is no longer able to meet the demand, the mixing heating circuits will be restricted as well.

6.6 Consumer circuits and swimming pool circuit

Summary

Other consumers, in addition to heating circuits HC1-HC3 and the cooling circuit, can be connected or controlled (e.g. door heating, swimming pools, etc.).

The controller can receive its temperature request via an Hx input and control the corresponding pumps via a relay output QX.

For the consumer circuits, the following settings are available:

An appropriately defined Hx input on the device or extension module (line 5950, 5960 or 6046, 6054, 6062) required to use consumer circuits / swimming pool circuit. The input can be defined as follows:

Cons request CC1, 2
Cons request 10V CC1, 2
Release swimming pool generation

Operating lines 5750 and 5751 are available to select whether the consumer circuits are used for heating or cooling.

The pumps are to be connected to the appropriately defined multifunctional relay outputs Qx.. (line 5890-5896 and 6030 - 6038).

The consumer circuit pumps (Q15 / Q18) are put into operation when there is a heat or refrigeration request at the respective input, or when excess heat draw is called for.

The swimming pool circuit (Q19) starts up when the release is pending at the corresponding input Hx and the swimming pool temperature is below the setpoint (line 2056).

Summary

The primary controller allows lower or higher flow temperatures by mixing to obtain flow temperatures for heating/cooling zones with setpoints higher or lower than those of the common flow.

The system pump can be used to overcome the pressure drop to remote heating/cooling zones.

Mixing valve boost To ensure adequate mixing, the actual value of the boiler flow temperature must be higher than the required setpoint of the mixing valve flow temperature, enabling that temperature to be controlled. The controller generates the boiler temperature setpoint based on the increase set here and the current flow temperature setpoint.

Mixing valve decrease To ensure adequate mixing in cooling mode, the actual value of the cooling flow temperature must be lower than the required temperature setpoint of the mixing valve flow since otherwise that temperature could not be controlled. The controller generates the refrigeration request based on the decrease set here plus the current flow temperature setpoint and sends the request to the refrigeration plant.

Actuator type Selection of the type of actuator determines the way the control action impacts the type of mixing valve actuator used.

Switching differential 2pos For a 2-position actuator, the 2-position switching differential must also be adapted. This is not required when using 3-position actuators.

Actuator: running time Setting the running time for the actuator used with the mixing valve.

Mixing valve Xp The proportional band Xp influences the controller's P-action.

Xp is the range by which the input signal (control variable) needs to change for the output signal (manipulated variable) to be adjusted across the whole correcting span.

The smaller Xp, the greater the change of the manipulated variable.

Mixing valve Tn Tn influences the controller's I-behavior.

Tn is the time required by the I-action with a given input signal (control variable) to bring about the same change to the manipulated variable as that produced immediately by the P-action.

The smaller Tn, the steeper/faster the slope.

Operating mode

Continuous operation

The boiler is constantly released and the minimum boiler temperature maintained is the parameterized TKMin.

The boiler will only be locked when all connected heating circuits are set to Protection mode and when there is no valid temperature request.

Automatic

The boiler will be released as soon as there is at least one valid temperature request. Once the boiler is released, the required minimum boiler temperature will always be maintained. The boiler will be locked when no valid temperature request is active. This means that with this operating mode, the boiler setpoint will be maintained at the required minimum only if a temperature request is active.

Auto mode, with extended burner running time

The boiler will be released as soon as there is at least one valid temperature request. When the boiler is released, the burner will be switched on when the boiler temperature drops below the request from the consumers. The required minimum boiler temperature is maintained only if the burner had to be switched on due to a request from one of the consumers. This means that since the boiler temperature can drop below its minimum, depending on the request, this operating mode leads to a smaller number of burner switching cycles and, therefore, longer burner on times.

Flow temp setpoint min/max

The controlled boiler temperature setpoint can be limited by setpoint minimum and maximum. These limitations can be regarded as protective functions for the boiler

In normal operation, minimum limitation of the boiler temperature is the lower limit value of the controlled boiler temperature setpoint, depending on the boiler's operating mode.

In normal operation, maximum limitation of the boiler temperature is the upper limit value of the controlled boiler temperature setpoint and, at the same time, setpoint of the electronic limit thermostat (TR).

i The setting range of setpoint minimum and setpoint maximum is limited by the setpoint of manual control.

Example when using boiler operating mode "Automatic":

The boiler temperature limitation OEM is a limit value for the min and max boiler temperature setpoint limitation (TKMax and TKMin).

Integrals for stage 2	The temperature-time integral is a continuous summation of the temperature differential over the time. In this case, the decisive temperature differential is the amount the temperature exceeds burner's switch-on or switch-off setpoint. Through the generation of the temperature-time integral, it is not only the period of time that is considered, but also the extent of the crossing. This means that when the exceed is significant, burner stage 2 will be released or locked earlier than when the exceed is small.

Mixing valve Xp	By setting the right proportional band Xp for the mixing valves actuator, the control behavior of the actuator is matched to those of the plant (controlled system). The proportional band Xp influences the controller's P-action. The P band Xp is the range by which the input variable x (controlled variable) must change to adjust the output variable y (manipulated variable) throughout the entire positioning range. The smaller the value the greater the jump. The illustration depicts the reciprocal value 1/Xp = Kp.

If a minimum burner running time is parameterized, the burner's switch-off point will be raised by half the boiler's switching differential within that minimum on time. If within the minimum burner running time, the boiler temperature exceeds the setpoint by more than the full switching differential, the burner will also be shut down before the minimum on time has elapsed. On completion of the minimum on time, the burner's switch-off point will be set to the boiler temperature setpoint plus half the switching differential.

TC function

The electronic temperature controller monitors boiler temperature (TKx) and triggers when the set limit value (TC setpoint) is exceeded, resulting in the shutdown of the burner.

During normal control operation and relay test, the Boiler temperature maximum limitation (TKMax) is used as the TR setpoint, whereas during manual operation, it switched to the "adjustable" value TKMaxHand.

The temperature controller can be switched on and off using the TC function parameter. It is, however, always active during manual operation.
