Remote control

Installation

The BM programming module can be used as remote control (e.g.

in the living room). Using a remote control makes both the walk to the boiler / installation room superfluous and provides additional functions (e.g. room temperature hook-up).

If there are several heating circuits with controllers from the Wolf control unit range, a single BM programming module can operate and adjust all heating circuits.

However, an individual BM programming module can also be allocated as remote control to each heating circuit.

Only a two-wire BUS is required for the use as remote control.

Installation information

- Install the wall mounting base (available as option) on an internal wall at a height of approx. 1.5 m above the floor.

- For an optimum room temperature sensor function, install the

BM programming module in a living room (reference room) that is representative of the entire accommodation or the entire house.

- The BM programming module must not be subject to draughts or direct radiated heat.

- The BM programming module must not be obstructed by furniture or curtains.

- In the reference room, all radiator valves must be fully opened.

Wall mounting base installation

- Remove the wall mounting base from its packing.

- Secure the wall mounting base on a flush-mounting box

(Ø 55 mm) or directly on the wall.

DHW circulation pumps are started and stopped within the enabled time according to demand (mixer circuit pump only in heating systems with a mixer circuit).

30 61 872_0407

30 61 872_0407

Control level 1

Summer mode (heating OFF)

Summer mode (heating OFF) means only cylinder heating in accordance with the switching times program. Frost protection for the central heating system and anti-seizing pump protection are enabled.

Constant DHW and central heating operation

The switching times program (1, 2 or 3) for heating and cylinder heating are disabled. With this setting, the day mode for central heating and cylinder heating are enabled for 24 hours. The heating circuit pump, mixer circuit pump and cylinder primary pump are started and stopped according to demand. The DHW circulation pump is started and stopped in accordance with the switching times program (mixer circuit pump only for heating systems with mixer circuit). No summer/winter changeover.

Constant setback mode

The switching times program (1, 2 or 3) for heating is disabled. With this setting, the heating operates in setback mode for 20 hours. The heating circuit and mixer circuit pumps are started and stopped according to demand.

The cylinder primary pump and the DHW circulation pumps are started and stopped in accordance with the switching times program (1, 2 or 3) (mixer circuit pump only for heating systems with mixer circuit).

Summer/winter changeover and ECO/RED are enabled.

Standby mode

Burner and circulation pumps are OFF, cylinder heating and pasteurisation are OFF, frost protection and anti-seizing pump protection are enabled.

Frost protection:

At outside temperatures below the set value (factory setting +2 °C), the boiler and mixer circuit pumps (mixer circuit pump only in heating systems with mixer circuit) run permanently, the mixers open.

Anti-seizing pump protection:

After no more than 24 hours idle, the pumps will run for approx. 20 seconds. This prevents the pumps from seizing up.

Flue gas test

The flue gas test is required by your flue gas inspector or a specialist contractor for measuring the emissions.

- This selection is not available if the BM programming module is installed as remote control (e.g. in a living room). In that case, the emissions test mode is activated at the boiler control unit via the heating water temperature selector and is indicated by the signal ring flashing in yellow.

- If the BM programming module is integrated into the boiler control unit, activating the emissions test mode is then indicated by an arrow in the display (next to the chimney sweep symbol) as well as by the signal ring flashing in yellow.

For the flue gas test function, see the next page.

1 3

Control level 1

Function: Flue gas test

Freestanding boilers:

The heating system will not operate in weather-compensated mode, when the emission test is running. Instead it operates at maximum output and tries to hold a mean constant boiler water temperature of 60 °C. Only the burner will operate, i.e.

the pump is OFF, if the boiler water temperature is lower than

60 °C. The boiler circuit pump will be started when the boiler water temperature exceeds 60 °C. The DHW cylinder primary pump only runs until the set DHW temperature has been reached. The burner is switched OFF when the max. boiler water temperature has been reached, if the heating energy supplied cannot be transferred.

Wall mounted boilers:

In emissions test mode, the heating system will not operate in weather-compensated mode, but with maximum output. Any previous cycle block will be cancelled. The heating circuit pump runs permanently.

The emissions test mode terminates either after 15 minutes or automatically, if the maximum flow temperature has been exceeded. For a repeat activation, turn the heating water temperature selector or the l.h. rotary selector (program selector) first anti-clockwise and then back into position .

14

Temperature selection

By turning the r.h. rotary selector, the required room temperature can be raised or lowered by a maximum of 4 K by turning the selector respectively anti-clockwise or clockwise. Subject to the direction of rotation, the arrow on the r.h. side of the display drifts either up or down.

Example:

+1: The set room temperature is raised by approx. 1 K.

- 1: The set room temperature is reduced by approx. 1 K.

If two arrows are displayed one above the other, the selected value will be between both.

Example:

Arrow 1 +1, arrow 2 +2: The set room temperature is raised by approx. 1.5 K.

0 corresponds to the selected room temperature (factory setting: day mode 20 °C, setback mode 12 °C).

The current room temperature will not be captured, if the BM programming module is integrated into the boiler control unit or if it is operated as remote control with room influence switched

OFF. The selected room temperatures are simply reference and calculating values for the heating curve; therefore the actual room temperature can deviate from these values.

Function explained

Heating curve

This setting will be made by the heating contractor for each heating circuit separately, subject to the heating system, the thermal insulation of the building and the relevant climatic zone.

Setting the slope will match the heating water temperature to these conditions.

The following diagram indicates an example applicable to the following heating system:

- Climate zone with an average minimum outside temperature of -14 °C

- Radiator for flow/return temperatures 60/50 °C, with direct control

- Thermal building insulation in accordance with current regulations

For all other conditions, match the slope to the prevailing circumstances. The slope must always be set so that, at the min.

outside temperature, the maximum flow temperature for the radiators or the underfloor heating system will be achieved.

As rule of thumb, a slope of 1.0 can be used for a radiator heating system, and a slope of 0.4 for underfloor heating systems in a well insulated house. Similarly, a slope of 1.4 can be used for a radiator heating system, and a slope of 0.8 for underfloor heating systems in a less well insulated house.

Room influence

Using room influence, room temperature fluctuations due to external heat or cold (e.g. solar irradiation, woodburning stove or open windows) can be compensated. Room influence will only work if the BM programming module is operated as remote control. A room temperature sensor is integrated into the programming module that captures the actual room temperature and compares it with the set value (day or setback temperature).

Activating room influence results in a correction of the weathercompensated calculated flow temperature via a room temperature sensor, either upwards (actual room temperature lower than the set room temperature) or downwards (actual room temperature higher than the set room temperature). The level of temperature correction can be set via system parameter A00 (see the

"Contractor" chapter).

The programming module will also function as a remote control; if it is fitted in a wall mounting base and is connected as a remote control, and the room influence (standard settings) has been enabled. If the room temperature is more than 1 K higher than the set room temperature, the heating circuit pump will be switched OFF (exception frost protection). The heating circuit pump will only restart, if the actual room temperature falls below the required set room temperature.

If this is not required, disable the room influence (standard settings) or the room temperature-dependent summer/winter changeover (parameter A11).

Using room influence, room temperature fluctuations due to external heat or cold (e.g. solar irradiation, woodburning stove or open windows) can be compensated. Room influence will only function if the BM programming module is operated as remote control. A room temperature sensor is integrated into the programming module that captures the actual room temperature and compares it with the set value (day or setback temperature). A set value deviation is multiplied with the set room influencing factor (0 to 20 K / K) and the heating curve.

The boiler or mixer is adjusted by this value.

Example:

Set room temperature 20 °C

Heating curve: 1.2

Actual room temperature 18 °C (e.g. after airing)

!

deviation 2 K

Room influence boiler circuit: Setting 4 K / K

Deviation 2 K x room influence 4 K / K x heating curve 1.2 = 10 K

The heating water temperature is raised by 10 °C to quickly raise the room temperature to the set value of 20 °C.

30 61 872_0407 3 9



Maximum heat-up time

This parameter specifies the maximum heat-up time. Starting from the changeover command of the time switch (minus selected maximum heat-up time), the boiler control unit calculates the latest possible start-up time for the changeover point, so that the required room temperature is achieved at the selected time.

Heat-up optimisation will not take place, if 0 has been entered for maximum heat-up time.

Example:

Start time heating mode in accordance with the time program:

6:00 h

Maximum heat-up time: 120 min

From 4:00 h, the boiler control unit starts to calculate the latest start-up point "t”, so that the required room temperature will be achieved by 6:00 h.

Fault messages

If a fault is indicated by the signal ring of the control unit flashing red, a fault code is displayed via the Wolf-control accessory with eBUS capability that allows a cause to be allocated using the following table.

This list of fault messages is designed to allow your heating contractor to trace the fault more easily.

Note: Faults that are not listed may be faults of the air-condition or ventilation control.
