the set comfort temperature. This temperature can, however, be altered by the user (for further information, see section 2.3.2). The installer sim- ply has to indicate whether or not a post-heater has been integrated into the ventilation system in menu P55 of the CC Ease operating unit dur- ing installation of the MTD-ERV 350 (for further information, see section 4.4).

The post-heater and the corresponding temperature sensor must be connected to the PCB panel (extended version) of the MTD-ERV 350 by the installer.

3.4.4 CO2 Sensor* in the Home

A CO2 sensor can be connected to the MTD-ERV 350.

This CO2 sensor allows the MTD-ERV 350 to regulate the CO2 concentration in the house. For this, a CO2 sensor is installed in one of the living rooms to measure the current CO2 concentration in the indoor air.

If the CO2 concentration is too high compared with the set (and hence highest admissible) CO2 concentration, the settings of the supply and ex- haust air fans will be gradually increased to re- duce the CO2 concentration. In this way the air in rooms with a high carbon dioxide concentra- tion that can occur, for example, during a party with a large number of people, can be quickly 'ex- changed' by additional ventilation. The user can set the maximum admissible CO2 content (within the given limits) himself in menu P27 via the CC Ease operating unit (see also section 2.3.7). The following CO2 concentrations can be set:

The starting point for this CO2 control is the assumption that the outside air is generally the fresh(er) air. The CO2 con- centration can be reduced by this system in

that (a) fresh air is drawn in faster with the supply

air fan, and (b) the old air is drawn off faster by the exhaust air fan. As soon as the CO2 concentra- tion in the house has reached acceptable values again, the settings of the two fans are gradually reduced again.

The CO2 sensor must be connected to the PCB panel in the electronics casing on the top of the MTD-ERV 350 by the installer.

3.4.5. RH Sensor* in the Home

A RH sensor can be connected to the MTD-ERV 350.

This RH sensor allows the MTD-ERV 350 to regu-

late the relative humidity in the house. For this, an RH sensor is installed in one of the living rooms to measure the current relative humidity of the indoor air.

If the humidity is too high compared with the set (and hence highest admissible) humidity, the set- tings of the supply and exhaust air fans will be gradually increased to reduce the humidity. Living rooms with an excessively high humidity, such as bathrooms during showering, are quickly freed of the humidity by the additional ventilation. Prob- lems due to high humidity can thus be avoided in this way. The user can set the maximum admis- sible humidity (within the given limits) manually in menu P28 via the CC Ease operating unit (see also section 2.3.7). The following humidity levels can be selected:

The starting point for this humidity control is the as- sumption that the outside air is gen- erally the dry (dri- er) air. The humid- ity can be reduced by this system in that (a) dry air is

drawn in faster with the supply air fan, and (b) the humid air is drawn off faster by the exhaust air fan. As soon as the humidity in the dwelling has reached acceptable values again, the settings of the two fans are gradually reduced again.
