Summer bypass
Summer bypass is a supplementary bypass channel that directs supplied air around the exchanger during cooler summer nights.
This prevents warm exhausted air from transferring its heat to cooler outdoor air and heating it up. Bypass works in an automatic
mode and its use is based on the temperature setpoint. Bypass is not used at an outdoor temperature lower than +8 °C, during
active Drying, Circulation or Stand-by. Automatic bypass function can be enabled or disabled in a mobile application.

The heat recovery system can be supplemented with following optional accessories - CO
panels (up to 8 pieces), VAC material and distribution elements.

6 6 . . 1 1 . . Stand-by Stand-by
When the heat recovery unit is in Stand-by mode, the air exchange is not active. Information from all the connected sensors is
available, being continuously evaluated. Thanks to connection to Jablotron Cloud, the heat recovery unit can be activated and its
settings can be changed any time. The unit in Stand-by mode responds to Boost function.
6 6 . . 2 2 . . Constant power Constant power
Constant power mode lets user adjust level of fan speed (levels 1 – 5). Depending on the temperature and humidity setpoint, the
system controls the bypass flap and connected peripherals. It controls turning of the heat exchanger flaps and drying flap based
on the current temperature and humidity.
6 6 . . 3 3 . . Auto mode Auto mode
Default mode of the heat recovery unit. This mode uses information from the connected CO
based on updated values. The ventilation output is adapted to the requirements for quality of the indoor environment. The unit
remains in this mode until it is switched to the Time Schedule mode. The sensors control the operation of the heat recovery unit
automatically; fan speed is adjusted according to data from sensors. There can be up to 8 CO
the HVAC technician can set which ones will be used to control the fan speed.
6 6 . . 4 4 . . Time schedule Time schedule
A mode in which user schedules switching between Automatic Mode, Stand-by Mode or a preset fan speed within a range of
five levels: 1 (minimum) – 5 (maximum). Time schedule can be activated or deactivated. If Time schedule is activated while one
of the functions is running, the function is immediately deactivated and the unit starts to run according to the Time schedule
mode. However, Time schedule mode cannot be activated while the Vacation function is on.

7 7 . . 1 1 . . Boost (forced ventilation) Boost (forced ventilation)
A top speed (5) function used if a fast, forced ventilation of the indoor premises is required. The unit is temporarily switched to
the maximum level, the fans working at the top speed. This function is available in any mode. It can be activated from the mobile
application (for any time interval), from the wall-mounted control panel (for a preset interval) or with a Boost switch connected to
the unit (for two preset intervals, one for short press and one for a 3 second long press). Boost switches are typically installed in
rooms where forced ventilation is needed, such as bathroom, toilet or kitchen. The time interval for Boost switch (for both short
and long press) can be adjusted, but only by the HVAC technician. If Boost is active, the time remaining until the expiration of this
function is displayed next to the respective symbol. After expiration of the given time, the unit returns to the previous mode.
