Where the pressure transmitter is installed on the supply air transportation system, the hose must be plugged to “+”. Where the pressure transmitter
is installed on the extract air transportation system, the hose must be plugged to “-”.

Example
Supply air temperature can be adjusted according to the temperature measured by the supply or extracted air temperature sensor and the temperature
which is set by the user on the remote control panel. User selected supply air temperature is maintained by the plate (or rotor) heat exchanger and
additional electric and/or water heater (optional). When the supply air temperature is under the set temperature, by-pass valve is closed (fresh ambient
air passes through the plate heat exchanger). If the device has the rotor heat exchanger, then rotation is stopped. In case the set temperature is not
reached, the heater (electric or water) is switched on and operates (heater valve is opened/closed if water heater is used) until the set temperature is
reached. When supply air temperature exceeds the set temperature, the heater is switched off in the first place. If the temperature is still greater than
the set temperature, the by-pass valve is opened or rotation is stopped if the device has rotor heat exchanger.
In the remote controller, temperatures (the set and the measured) are displayed as degrees Celsius (°C).
Room air temperature can be adjusted not only according to the supplied air temperature sensor, but also according to the extracted air sensor (see
FLEX panel description II.6.5.3 for details on selecting this feature).
When control algorithm of the extracted air sensor is selected, then supply air temperature is adjusted based on estimated additional received heat
(heat emitted by the sun, electric heaters, etc.). Thus the energy for excessive heating of the supply air is saved. The room is heated based on the
estimated room temperature to provide the desired room temperature microclimate.
Supply air electric heater (resistance heating elements if the electric heater is used) is controlled by the ESKM (Triac electric heater control module)
controller using the PWM signal. If the water supply air heater is used, then the actuator is controlled using RG1 controller with analogous 0-10V DC signal.
“BOOST” feature
Fans are started at maximum speed and “BOOST” is displayed in the remote control panel (FLEX). “BOOST” feature is inactive if the heat exchanger
protection is triggered. When triggering signal for this function disappears, the desired operation period for this feature can be selected in the control
panel (FLEX) (see FLEX panel description II.6.6 for details on selecting this feature).
There is boost time setting in minutes (factory setting: Off) in the user menu item Add.Func. For example, if 5min is set, then in case the signal is lost
