TosettheMTD-ERV 350(afterinstallation),proceed as follows:

•Switch the MTD-ERV 350 to the setting mode.

–Press simultaneously for two seconds on " " and " ".

–Wait until "InR" appears on the CC Ease display.

In setting mode, bypass and preheater are always deactivated. The MTD-ERV 350 switches the setting mode off again automatically after 30 minutes.

•Close all windows and outside doors.

•Close all inside doors.

•Check thepresenceofaircirculationsystemsin the building (at least 12 cm2 per l/s).

The air circulation systems in the build- ing must achieve at least 12 cm2 per l/s.

•Check whether both fans function in the three speed ranges.

•Switch the MTD-ERV 350 to the high position.

•Install all the valves and set them according to

the instructions or as in the reference dwelling. If no data are known:

–Install the valves and open them as far as possible.

–Measure theairvolumes,firstthesupplyair and then the exhaust air.

–differ by more than approx. 10% from the nominal air volumes and the majority of the deviations are in the plus range, adjust the fan so that all the deviations are in the plus range. If the majority of the deviations are in the minus range, adapt all the devia-

Use the MTD-ERV 350 air specification diagram for setting the fans.

•If the previously set air volumes still differ too much:

– Adjust the valves further.

•Checkthewholesystemagainafteradjustment of all the valve stages.

•Switch the MTD-ERV 350 (back) to ventilation position 2.

4.6Maintenance by the Installer

AsinstalleryouhavetoservicetheMTD-ERV 350as follows:

•Inspect the heat exchangers and fans

•Clean the filter if a preheater is installed.

Thesemeasuresaredescribedinmoredetailbriefly in the following sections.

If these measures are not performed (regularly), there is a danger that the MTD-ERV 350 will cease to function cor- rectly.

4.6.1 Inspection of Heat Exchanger and Fans

Thefansandtheheatexchangermustbeinspected every 4 years.

•Remove the mains plug (A) from the plug sock- et.

•Pull the filters (B) out of the MTD-ERV 350.

•Remove the front plate by removing the screws

(C).

•Push the front plate in the direction of the ar- row and remove it from the MTD-ERV 350.

•Remove the sealing plate by removing the screws (D).

ERV 350, ERV 365 specifications

The MTD ERV 365 and ERV 350 are advanced energy recovery ventilation (ERV) systems designed to enhance indoor air quality and energy efficiency in residential and commercial buildings. These units utilize cutting-edge technologies to transfer heat and moisture between incoming and outgoing air streams, optimizing the temperature and humidity levels of the conditioned air.

One of the main features of the MTD ERV 365 is its high energy recovery efficiency. Equipped with a specially designed heat exchanger, this ERV can reclaim a significant portion of the energy from the exhaust air, reducing the heating and cooling load on HVAC systems. This results in lower energy bills and decreased environmental impact. The ERV 350 offers similar benefits but is tailored for slightly smaller spaces, making it suitable for various residential applications.

Both models are constructed with durability in mind, featuring robust housing and weather-resistant materials that ensure long-lasting performance. The MTD ERV series is designed to withstand varying environmental conditions, ensuring reliable operation in challenging climates. Additionally, noise-reduction technology minimizes operational sounds, promoting a peaceful indoor environment.

User-friendly controls are another highlight of the MTD ERV systems. They come equipped with intuitive interfaces, allowing users to easily adjust settings, monitor performance, and receive maintenance notifications. Advanced sensors provide real-time data on indoor air quality parameters, ensuring optimal operation based on the specific needs of the environment.

Installation and maintenance are made straightforward with these ERV units. They feature a compact design that facilitates integration into existing HVAC systems or new constructions. Filters are easily accessible for routine cleaning or replacement, maintaining peak performance over time.

Furthermore, both the MTD ERV 365 and ERV 350 are designed with sustainability in mind. Using materials that are recyclable and energy-efficient components contributes to a reduced carbon footprint.
