2 Product description

2.1 Which nomenclature is used?

• System control: Instead of VRC 720
• Remote control: Instead of VR 92
• FM3 or FM3 functional module: Instead of VR 70
• FM5 or FM5 functional module: Instead of VR 71

2.2 What is the effect of the frost protection function?
The frost protection function protects the heating installation and flat from frost damage.

At outdoor temperatures

• Below 4 °C for longer than four hours, the system control switches the heat generator on and regulates the target room temperature to at least 5 °C.
• Above 4 °C, the system control does not switch the heat generator on, but it monitors the outdoor temperature.

2.3 What do the following temperatures mean?
Desired temp. is the temperature to which you want to heat or cool the living rooms.

Set-back temp. is the level below which the temperature in the living rooms does not fall when outside of the time periods.

Flow temp. is the temperature at which the heating water leaves the heat generator.

Domestic hot water temperature is the temperature to which the domestic hot water cylinder is to be heated.

2.4 What is a zone?
A building can be divided into multiple areas, which are known as zones. A different requirement can be placed on the heating installation in each zone. Examples for dividing into zones:

• Underfloor heating (zone 1) and a radiator system (zone 2) are available in one building.
• A building is made up of several self-contained residential units. Each residential unit has its own zone.

2.5 What is the circulation?
An additional water pipe is connected to the domestic hot water pipe and forms a circuit with the domestic hot water cylinder. A circulation pump facilitates the continuous circulation of domestic hot water through the pipework system which means that hot water is immediately available, even at more distant draw-off points.

2.6 What is a fixed value control?
The system control regulates the flow temperature to two fixed temperatures, which are independent from the room or outdoor temperature. This control is suitable for a door air curtain or swimming pool heating, for example.

2.7 Prerequisites for heating mode

• The outdoor temperature must be lower than the temperature that the competent person has set in the MENU | SETTINGS | Installer level | Installation configuration | Circuit 1 | OT switch-off threshold: °C function.

2.9 What is meant by “time period”?
Example of heating mode in the mode: Time-controlled

You can divide a day up into several time periods (1) and (2). Each time period can comprise an individual start time and end time. The time periods must not overlap. You can assign a different desired temperature (3) to each time period.

Example:
16:30 to 18:00; 21 °C
20:00 to 22:30; 24 °C

The living rooms are heated to the desired temperature within the time periods. In the times outside of the time periods (5), the living rooms are heated to the lower set-back temperature (4) that is set.

Example of cooling mode in the mode: Time-controlled

You can divide a day up into several time periods (1) and (2). Each time period can comprise an individual start time and end time. The time periods must not overlap. You can set a desired temperature (3) that is assigned to all time periods.

Example:
16:30 to 18:00; 24 °C
20:00 to 22:30; 24 °C

The living rooms are cooled to the desired temperature within the time periods. During the times outside of the time periods (4), the living rooms are not cooled.

2.10 What is the effect of the hybrid manager?
The hybrid manager calculates whether the heat pump or the additional boiler covers the heat demand cost-effectively. The decision-making criteria are the set tariffs in relation to the heat demand.

To ensure that the heat pump and the additional boiler can work effectively, you must enter the tariffs correctly. See MENU | SETTINGS. Otherwise, increases costs may arise.

2.11 Preventing malfunctions

• Do not cover the system control with furniture, curtains or other objects.
• If the system control is installed in the living room, open all of the thermostatic radiator valves in this room fully.

2.12 Setting the heat curve

The figure shows the possible heat curves of 0.1 to 4.0 for a target room temperature of 20 °C. If, for example, heat curve 0.4 is selected, a flow temperature of 40 °C is maintained at an outdoor temperature of -15 °C.

If the heat curve 0.4 is selected and 21 °C is specified for the target room temperature, the heat curve is then translated, as shown in the figure. The heat curve is displaced according to the value of the target room temperature along axis a which is angled at 45°. At an outdoor temperature of -15 °C, the control system provides a flow temperature of 45 °C.

6.1 Fault
How to respond if the heat pump fails
The system control switches to limp home mode, i.e. the back-up boiler supplies the heating installation with heating energy. During installation, the competent person has restricted the temperature for limp home mode. You can feel that the domestic hot water and heating are not becoming very hot.

You can select one of the following settings until the competent person arrives:

Off: The heating and domestic hot water only become moderately hot.

Heating: The back-up boiler takes over the heating mode; the heating becomes hot and the domestic hot water is cold.

DHW: The back-up boiler takes over the domestic hot water mode; the domestic hot water becomes hot and the heating is cold.

DHW + heat.: The back-up boiler takes over the heating and domestic hot water mode; the heating and domestic hot water become hot.

The back-up boiler is not as efficient as the heat pump, meaning that using only the back-up boiler to generate heat is expensive.
