Component description
10.2.1.1 Fans
Fans have an external EC type rotor which can be steplessly controlled individually 16–100%. The motor bearings are
life time lubricated and maintenance free. It is possible to remove the fans for cleaning, see "User Manual" for more
information.
10.2.1.2 Filters
The factory installed filters are of filter quality M5/ePM10 50% for the supply air and M5/ePM10 50% for the extract
air filter. The filters need to be replaced when polluted. New sets of filters can be acquired from your installer or
wholesaler.
Filter quality F7/ePM1 60% can be installed for supply air filtering.
The filter type is labelled on the top of the filter
10.2.1.3 Heat exchanger
SAVE VTR 150/B is equipped with a rotating heat exchanger. Required supply air temperature is therefore normally
maintained without adding additional heat.
The heat exchanger is removable for cleaning and maintenance, see "User Manual" for more information.
10.2.1.4 Main circuit board
The main circuit board controls all functions and the unit.
It is possible to connect external accessories to a free terminals on the main circuit board.
10.2.1.5 Connection box
Connection box is placed outside of the unit. It contains connection board. All external accessories can be connected to
the unit via connection board with freely configurable terminals.
10.2.1.6 Temperature sensors
Four temperature sensors (NTC, 10 kΩ at 25°C) are included in the unit from factory and positioned in the correspond-
ing air chambers.
The sensors are connected to the main print card. See wiring diagram for more information.
10.2.1.7 Humidity sensor
Relative humidity sensor (RHS/EAT) is included in the unit at factory and positioned in the extract air chamber.
The sensor also measures the temperature of extracted air.
The sensor is connected to the main circuit board. See wiring diagram for more information.
10.2.1.8 Electrical Re-heater battery
The re-heater battery is positioned in the supply air chamber.
The re-heater is activated by a relay and switches on if the supply air temperature is lower than the set point and
switches off if one or more of the following conditions are met:
1. If the supply air temperature is above the set point.
2. If the over heat protection is activated or the sensor is malfunctioning.
3. If the emergency thermostat is triggered or broken.
