Phase 1 - stale and hot air is extracted from the room. While flowing through the heat exchanger ceramic, heats
it. So it moved up to 97% of the thermal energy. In 65 seconds the heat exchanger is heated and the unit switches
to the second phase.
Phase 2 - the fresh air from the outside flows through the heat exchanger ceramic that heats the air to room
temperature. In 65 seconds the ceramic exchanger cools and the unit switches to "Phase 1".
2.3 OPERATING LIMITS
The fan must only be used for indoor applications, with room temperature between -30° and +50° c, with relative
humidity below 97%.
3. OPERATION OF MORE UNITS CONNECTED TO EACH OTHER
When in a room more than one KERS is installed, their operation should be placed in sync so as not to generate
pressure imbalances in the environment. The devices must be connected in series between them (see section:
electrical connection), so that when half of them works in extraction (phase 1), the other half work in supply
(phase 2).
By connecting them in series, only one remote control which operates on the first device (“Master”), can control
all the KERS installed in sync. Also units that operate in separate rooms can be connected in series, on condition
that they have similar requirements between them and can be controlled by the same remote controller.
Up to 10 KERS units can be linked in this way.
4. ELECTRICAL CIRCUITS
4.1 ELECTRICAL EQUIPMENT
The board is constructed and wired in accordance with "Low Voltage ” and EMC directive.
The fans, equipped with EC reversible and low-power motors, adjustable between 3.6 W and 5.2 W are extremely
quiet. Once the fan is installed in the properly prepared opening (see section 9.4), connect to a power source
(230 V AC 50 Hz).
