2.1.6 Boiler enable input

When setting the system type, the parameter "Boiler enable input available" is preset to enable potential analysis of an external floating release or start contact.

Boiler enable input available YES

This is set if the boiler enable input is available. As long as the contact is closed, the controls operate according to the speci‐

fied operating mode. If the external contact is opened, the boiler loses the enable and follows the shutdown procedure. As soon as the handle is opened, the controls cease to accept any heat re‐ quirement (e.g. flue gas thermostat of a supply boiler).

Boiler enable input available NO

This is set if there is a boiler start input or no allocation. As long as the contact is open, the controls operate according to the speci‐

fied parameters. If the external contact is closed, the boiler starts and works in continuous operation. (e.g. heat requirements of a heating fan)

Note: No handle required for operation.

❒

If the boiler is enabled or started by the parameter, it goes at least to "Heating"

status, even if the signal has stopped in the meantime. Only then does the boiler follow the shutdown procedure.

2.2.9 Setting the module address

For hydraulic modules or heating circuit modules it is necessary to set the required or‐ der with the module addresses. The first board of a module type should always have the address 0, so that the standard hydraulic systems set do not have to be subse‐ quently configured. For further module types ascending module addresses (address 1

- 7) are set. A hydraulic module with address 0 is included in standard delivery. If a second hy‐

draulic module is also installed, address 1 is set.

4.8 Boiler modes

4.8.1 Explanation of terms

Boiler time The time in which the boiler is producing heat, i.e. during this time the boiler is adjus‐

ted to its boiler temperature setpoint. Outside this time there is no heat available for the heating system.

❒

If there is a storage tank, the boiler time is replaced by the storage time

⇨ See "Heating times of the boiler" [page 78]

Storage tank loading time The time in which the storage tank can be loaded by the boiler, provided that the crite‐

rion for starting the boiler is met ("Boiler start if difference between boiler setpoint and top store is larger“ parameter).

❒ Storage tank loading only takes place within the defined time window.

⇨ See "Heating times of the storage tank" [page 73]

Heating time The time in which the heating circuit is supplied at the desired temperature. Outside

this time (setback mode) the heating circuit is supplied at reduced temperature.

❒ Requirement: a sufficiently high temperature in the boiler or top storage tank.

⇨ See "Heating times of the heating circuits" [page 58]

DHW tank loading time The time in which DHW tank loading is released.

❒ Requirement: The DHW tank temperature is below the minimum value and the

boiler or storage tank temperature is sufficiently high.

⇨ See "Heating times of the DHW tank" [page 64]

Operation

Operating Instructions Lambdatronic H 3200 T4 - Touch | B0820314_en 39

4.8.2 Transition op. without storage tank

In transition operation without a storage tank the boiler only produces heat during the specified boiler times. Outside these times the boiler follows the shutdown procedure and switches to "Standby" status. It is, therefore, important to note that in this mode the heating circuits and DHW tank are only supplied with heat during the boiler times.

In example 1 the boiler times have been set to cover the necessary heat requirement. The heating times and DHW tank loading times have been set within the boiler time range, with the heating time being extended approximately one hour beyond the boiler time. This allows the residual energy in the boiler to be used by the heating circuits after the end of the boiler time.

Note that outside the boiler times for setback mode, heat is only available until the boiler temperature falls below the setting value (parameter "Pumps start at").

Boiler heating time 1

Heating time 1 Heating time 2

DHW tank loading time 1 DHW tank loading time 2

4.8.3 Transition op. with storage tank

In transition operation with storage tank the boiler only produces heat if the storage tank actually requests heat within the specified storage tank loading time. Outside these times the boiler is in “Standby" status.

The heating times should be set within the storage tank loading times so that the pro‐ vision of heat is guaranteed over the entire heating time.

Note that the heating circuit and DHW tank are only supplied with heat if the storage tank temperature is sufficient for the requirement.

Example 1:

Heating time 1 Heating time 2

DHW tank loading time 1

Setback mode

Storage tank loading time 1

DHW tank loading time 2

Transition operation with storage tank

Time

Tip. In systems with a storage tank and solar panels, choose the storage tank loading time so that solar energy can be used.

In order to ensure that there is sufficient heat at the start of the DHW tank loading time and heating time, we recommend setting the storage tank charging time to begin be‐ fore the start of the DHW tank time or heating time.

4.8.4 Winter op. without storage tank

In winter operation the boiler produces heat around the clock, in other words it tries to maintain its boiler temperature setpoint 24 hours a day. The boiler time settings are ignored in this mode.

The heating times and DHW tank loading times can be distributed throughout the day as required.

Example 1:

Heating time 1 Heating time 2

➥ The grate is opened and it remains open until the specified time has elapsed

(parameter "Stoker full").

➥ The grate is closed again and a suitable quantity of fuel for ignition is fed in.

❒ While the boiler is heating up, open the "Current values" menu and scroll to

the parameter, "Current status runtime"

❒ Observe the following times (current and maximum) during the second heating up

process and compare with the preset standard values:

▪ Time until fuel falls onto the lifting grate: …….. seconds

(no fuel should fall into the ash chamber)

▪ Time until a sufficient quantity for ignition is present: …….. seconds

(approx. a quarter of the grate is covered with fuel, at least up to the igniter tube)

☞ For this procedure it is necessary to open the boiler door, which is screwed shut,

after preparation.

☞ The combustion chamber must only be opened in the course of initial start-up or

by qualified technicians during operation.

❒ After a suitable quantity of fuel for ignition has been fed in, quickly close the com‐

bustion chamber door and screw it shut.

❒ If you notice any deviations in the status runtimes in the menus, "Ignition" and

"Fuel feed", adjust them.

As well as the status runtimes, you should also check the parameter, "Slide-in during ignition", and adjust it if necessary.

☞ In reality this parameter depends on the fuel used and therefore should be set by

the customer service technician during initial startup.

☞ When you change the fuel (supplier, type of wood etc.) you must have the param‐

eters changed by a customer service technician. Flash fire hazard!

❒ The following parameters (depending on the configuration) can/should be set ac‐

cording to the customer's wishes:

▪ Desired boiler setpoint

Adjusting the feed output of the feed screw

NOTICE! This adjustment must ONLY be carried out by a qualified technician.

If an original Froling discharge system is installed, no adjustments are necessary, as it has already been adapted to the boiler.

If a discharge system from a third-party manufacturer or an older discharge system with a higher feed output is used, the parameter, "Time feed screw is on un-

til stoker screw

, must be adjusted, as the stoker could be overfilled otherwise. For discharge systems with higher feed outputs, the feed screw to stoker screw ratio must be reduced.

Procedure:

Open the gravity shaft cover briefly at regular intervals during operation and check the area above the rotary valve to see if fuel is jammed. If this is the case, the parameter "Time feed screw is on until stoker screw", must be reduced.

Please note that when this parameter is changed, the values of the parameters "The

time until the stoker is full is", "The time until the stoker is empty is" and "Feed time until there is a fuel quantity suitable for ignition" must be reset.

❒ Shorter time feed screw is on until stoker screw

➥ The times are reduced!

As the infeed of the T4 relates to the feed screw, the parameter, "Minimum loading rate", must also be adjusted. If the time feed screw is on until stoker screw is re‐ duced considerably (= high feed output of the feed screw), this means a low feed rate during heating. For this reason the minimum feed rate should be set very low for the first heating process (~1%). Calculate the average feed rate at full load at "Heating" status and set the parameter, "Minimum loading rate" to about a quarter of this value. If the feed screw has a higher feed output, the parameter, "Slide-in during ignition" must also be reduced. Set this value to around half the average feed rate at full load.

Parameter Description

Should this heating circuit heat when there is DHW tank priority?

NO Generally the heating circuits are released with active DHW tank priority

only when the DHW tank is fully charged. If this parameter is set to "YES", the DHW tank priority for this heating circuit is deactivated.

1 NOTE: Only valid for multiple house systems (variants).

Allocation of the heating source for this heating circuit: 0 = Boiler, 1 = Storage tank 01, ...

High temperature requirement be‐ cause of DHW tank 1 loading

NO If DHW tank 1 is supplied directly from the heating circuit as well as the

isolating valve, this parameter must be set to “YES”. If there is a require‐ ment from the DHW tank and the criteria for DHW tank loading have been met, the isolating valve immediately clears the way for boiler loading. The heating circuit pump starts running as soon as the “Load if tempera- ture difference between boiler and DHW tank is” criterion is reached. Once DHW tank loading is complete, the heating circuit pump will stop, the isolating valve will remain active for a specified period of time and the heating circuit mixer will close. If time has run out, the heating cir‐ cuit will go back to being supplied on a weather-compensated basis.

NOTE: Parameter only available with heating circuit 1 and generally only used in conjunction with the unit model of the P1 Pellet pellet boiler!

High temperature requirement be‐ cause of DHW tank loading

NO If this parameter is set to YES, the remote line is operated according to

the set heating curve + overcharge. Whilst the DHW tank is loading, the remote line is supplied for a short time at a higher temperature, but once the DHW tank is loaded, it is supplied again according to the heating curve.

NOTE: Parameters for heating circuit 2 only!

For high temperature requirement don't look at DHW tank 01

NO If DHW tank 1 is positioned in front of the network mixer, it should not af‐

fect the temperature control of the remote line, therefore this parameter should be set to YES.
