The unit has the following operating principle:
Warm stale extract air from the room flows to the unit, where it is filtered.
Then the air is moved through the rotary heat exchanger and is exhausted outside with the exhaust fan.
Clean cold air from outside is moved to the supply filter. Then filtered air flows through the rotary heat exchanger and the electric heater (for the Komfort
Roto EC S(E) units) where it is warmed up to the set value and is moved to the room with the supply fan.
Heat energy of warm extract air is transferred to clean intake fresh air from outside and warms it up in the rotary heat exchanger.
Heat recovery minimizes heat and space losses, heating expenses in cold seasons and cooling expanses in warm seasons.
The unit is equipped with an additional extract spigot for connection of a kitchen hood.
The kitchen hood must be equipped with an air damper to shut off the exhaust duct when the kitchen hood is not in use.

AUTOMATIC CONTROL SYSTEM DESIGN AND OPERATION
The automatic control system comprises a Carel controller (PCO5 compakt), an outdoor air temperature sensor, a supply air temperature sensor, a temperature
sensor of an exhaust duct, a room temperature sensor (when using the th-Tune with the temperature sensor), a humidity sensor in an exhaust air duct, relays,
circuit breakers and a supply transformer.
The unit may be equipped with a humidity sensor (option) that helps maintaining humidity level in premises.
If the humidity level in the exhaust air duct (%) exceeds the set point the„AUTO“ speed mode is activated.
Fan speed is increased using a PID law for humidity reduction.
As the humidity drops down below the set point the unit returns to the previous operation mode.
The unit is controlled via the th-Tune (Komfort Roto EC S(E) S17) or pGD1 (Komfort Roto EC S2(E) S18) control panel.
The automatic control system enables safe automatic operation of the unit in the Auto or Ventilation mode (only with the pGD1 control panel).
In the Auto mode the unit maintains the indoor temperature at the set level by controlling operation of the heat exchanger, the heater and the condenser
unit.
In the Ventilation mode the heat exchanger and the heater are switched off.
The supply and exhaust fan speed is set for each speed stage as a percentage from the maximum rotation speed.
The temperature is set up by changing the„Setpoint“ parameter value.
The fans can be operated according to a daily schedule (up to 4 time ranges).
The Automatic Speed Drop mode is enabled when the air temperature is low. In this mode the fan speed is adjusted according to the supply air temperature.
The speed is reduced at temperature dropping and is restored to the initial setting if the set temperature permits.
