It comprises two air fl ows that hygienically exchange their energy. · Polluted air is drawn off by the exhaust air fan (A) from, for example, the kitchen, toilet and shower (B). · The heat exchanger (C) absorbs the heat from the exhaust air. · The supply air fan (D) draws in fresh air from outside (E). · The heat exchanger (C) heats up the intaken air using the heat absorbed from the exhaust air. · If a moisture exchanger is installed (option), moisture is also transferred from the exhaust air to the supply air (for further information, see section 2.1.6). · The heated fresh air is delivered into the living rooms and bedrooms (F). · The now cooled polluted air from the kitchen, bathroom and toilet is discharged into the atmosphere (G). · The bypass (H) allows the exhaust air to be discharged to the atmosphere without passing through the heat exchanger so that no heat is transferred to the fresh air (for further information, see section 2.1.3). · The preheater (I) (option) ensures preheating of outside air so that balanced ventilation with heat recovery is assured even with moderate to severe frost (up to 150 m./h at -15° C) (for further information, see section 3.4.2). · The post-heater (J) (option) additionally heats the supply air (after it has already been heated in the heat exchanger) before it is delivered into the living rooms (for further information, see section 3.4.3). T he balanced ventilation system contributes to energy saving, a healthy room climate and an optimum living climate and prevents problems with moisture. 3.4. Additional Options Only for MTD-ERV 350 Luxury versions, with the exception of the preheater that can be installed in any MTDERV 350. Please refer to the identifi cation plate on the top of the MTD-ERV 350 to determine whether you have a basic or luxury version of the system. These are external devices that can be connected to the MTD-ERV 350 Luxury versions (preheater also to Basic versions). 3.4.1. Preheater in MTD-ERV 350 All MTD-ERV 350 systems with “VV” in the device name (see identifi cation plate on the top of the MTD-ERV 350) are equipped as standard with a preheater. All other MTD-ERV 350 versions can be equipped with a preheater as an option. The preheater is a heating element that is installed in the outside air duct of the MTD-ERV 350 just upline of the heat exchanger. The preheater heats the cold outside air before it reaches the heat exchanger in the event of moderate to severe frost. In this way the heat exchanger is protected against freezing in addition to the standard frost protection system. The advantage of the preheater compared with the standard frost protection system is that balanced ventilation can be maintained even in the event of frost. In the event of a frost risk, the intake of out 3 Menu P29: Setting the rate of increase .. Rate of increase Minimum 1% .. Rate of increase Standard 10% .. Rate of increase Maximum 99% 20 Function of the System side air no longer has to be temporarily reduced (or even interrupted for a short time) in order to prevent condensation freezing in the heat exchanger. Instead the preheater is temporarily switched on. In addition, this option offers greater comfort as the supply air is preheated to more or less room temperature. The preheater is switched on and off automatically. As soon as the temperature of the outside air is below 0 oC for a certain period, the air duct of the preheater is opened and the preheater is switched on to heat the intaken outside air to at least 1 oC. Here a temperature sensor in the supply air duct of the MTD-ERV 350 measures the temperature. This preheating control ensures balanced ventilation up to a maximum of 150 m./h at -15 oC. The user cannot infl uence the automatic preheater control. The installer has to modify the preheating control, for example during installation of the MTD-ERV 350, in menu P52 via the CC Ease operating unit (for further information, see section 4.4). The preheater and the corresponding temperature sensor must be connected to the PCB panel behind the front panel of the MTD-ERV 350 by the installer. In the event of retrofi tting, install...
