The RH sensor must be connected to the PCB panel in the electronics casing on the top of the MTD-ERV 350 by the installer.

3.4.6 Underground Geothermal Heat Exchanger*

As an option, the ventilation system can also be equipped with a geothermal heat exchanger.

can modify the automatic control of the geother- mal heat exchanger to a slight extent in menu P61 at the CC Ease operating unit, if necessary.

The geothermal heat exchanger and the corresponding temperature sensor must be connected to the PCB panel (extend- ed version) of the MTD-ERV 350 by the installer.

The geothermal heat exchanger is an addition- al underground air duct at a depth of at least 1 metre and with a length of 20 to 40 metres that forms part of the ventilation system. The geo- thermal heat exchanger allows the outside air to be admitted to the house under ground instead of above ground. The heat of the soil is thereby given off to the outside air as it flows through the geothermal heat exchanger.

The geothermal heat exchanger is thus an out- standing solution both in winter and in summer. In frosty weather, the outside air can be heated by the underground geothermal heat exchanger before it enters the house via the MTD-ERV 350. During hot weather in the summer, on the other hand, the outside air can be cooled by the un- derground geothermal heat exchanger before it enters the house via the MTD-ERV 350.

The geothermal heat exchanger functions au- tomatically. A temperature sensor installed any- where on the outside of the house measures the temperature of the outside air. As soon as

3.4.7 Chimney Sweep Control

Apart from the chimney sweep control set as standard in the software, an additional unit can be connected to the PCB panel (extended ver- sion) of the MTD-ERV 350 as an option that can switch off the fans of the MTD-ERV 350 via a float- ing contact.

By means of a pressure sensor installed in the room in which the hearth to be monitored is in- stalled, the unit measures the pressure in the room with the hearth. The pressure in the room in which the hearth is installed and the adjacent rooms must not exceed - 4 Pa so that fumes and smoke cannot enter the house. At a pressure higher than - 4 Pa, the fans of the MTD-ERV350 are switched off. Malfunction code "E4" appears on the display. In this case, please contact the installation company that installed the pressure sensor and/or the heating. There is probably a problem with the discharge of the fumes from the hearth.

The additional unit and the correspond- ing pressure sensor do not belong to the standard scope of supply of the MTD- ERV 350.

The additional unit and the correspond- ing pressure sensor must be connected to the PCB panel (extended version) of the MTD-ERV 350 by the installer.

the temperature of the outside air is between 0 and 15 oC in winter months and between 10 and 25oC in summer months, the geothermal heat exchanger is activated to allow the outside air to flow through the heat exchanger. The user can- not influence the automatic geothermal heat ex- changer control system. The installer simply has to indicate whether or not a geothermal heat ex- changer has been integrated into the ventilation system in menu P60 of the CC Ease operating unit during installation of the MTD-ERV 350 (for further information, see section 4.4). The installer

The installer cannot influence the automatic chim- ney sweep control system. It reacts to settings at the PCB panel (extended version) stored in the software. The installer simply has to indicate whether or not a chimney sweep control system has been integrated into the ventilation system in menu P50 of the CC Ease operating unit during installation of the MTD-ERV 350 (for further infor- mation, see section 4.4).
