Product description

Which nomenclature is used?

• Remote control: Instead of VR 92
• ystem control: Instead of VRC 720
• FM5 or FM5 functional module: Instead of VR 71

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.

What is a zone?
A building can be divided into multiple areas, which are known as zones. A dif-ferent requirement can be placed on the heating installation in each zone.

Examples for dividing into zones:

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

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

1. Time period 1
2. Time period 2
3. Desired temperature
4. Set-back temperature
5. Outside of the time periods

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 temper-ature (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

• A Time
• B Temperature
  1. Time period 1
  2. Time period 2
  3. Desired temperature
  4. Outside of the time periods

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. Dur-ing the times outside of the time periods (4), the living rooms are not cooled.

Preventing malfunctions

• Do not cover the remote control with furniture, curtains or other objects.
• Ensure that all thermostatic radiator valves in the room where the remote control is installed are fully open.

Set-up, electrical installation

Requirements for the eBUS line
Observe the following rules when routing the eBUS lines:

• Use twin-core cables.

• Never use shielded or twisted cables.

• Use only appropriate cables, e.g. NYM or H05VV (-F/-U).

• Observe the permissible total length of 125 m. In this case, a conductor cross-section of ≥ 0.75 mm² up to 50 m total length and a conductor cross-section of 1.5 mm² from 50 m.
  In order to prevent faults in the eBUS signals (e.g. due to interferences):

• Maintain a minimum clearance of 120 mm to power supply cables or other electromagnetic sources of interference.

• For parallel routing to mains connection lines, guide the cables in accordance with the applicable regulations, e.g. on cable trays.

• Exceptions: For wall breaks and in the electronics box, it is acceptable to not reach the minimum clearance.

Installing the remote control and connecting to the heat generator

• The heating installation must be decommissioned before work is carried out on it.
• Only qualified electricians may carry out the electrical installation.

Start-up
