PF14 = 500 and PF15 = 1500 ppm.
Speed 1 for measured value < 500 ppm
Speed 2 for measured value between 500 ppm (inclusive) and 1500 ppm Speed 3 for measured value

SETTING THE HEATING ON THE RETURN AIR TEMPERATURE
You can choose to control the temperature either using the return air or the supply air.
•
Pb01=0: supply air
•
Pb01=1: return air
Note.
If the return sensor is deactivated or in a fault state, the parameter
Pb01
will remain at value 0 and it will not be
possible to activate temperature management using the return air sensor.
7.3
OFFSETTING THE SETPOINT IN ECONOMY MODE
This function enables you to change the setpoint. In economy mode, it is possible to offset the setpoint (SHPM/SHPR
and SCPM/SCPR) by ± 5°C (parameter Pb05 Summer mode and parameter Pb06 Winter mode).
7.4
BOOST (STARTING THE APPLIANCE OUTSIDE OF THE TIME SLOT)
Press the LEFT and RIGHT buttons simultaneously to use a set speed (
parameter PF36)
during a given operating time
(
parameter PF27
). Activate the function via parameter
PF35
:
•
PF35 = 0: Disabled.
•
PF35 = 1: COMFORT Boost speed.
•
PF35 = 2: Boost speed determined by parameter PF36.
Press the same buttons (detection of rising edge) to stop the function. The machine remains in boost mode until the
end of boost mode or until the LEFT and RIGHT buttons are pressed. However, it does not allow the value to be changed
(speed, flow rate, etc.). Post-ventilation will be taken into account when the function is stopped.
7.5
NIGHT-TIME VENTILATION
The night-time ventilation function (parameter
PF30
) is based on energy savings during the summer season. This
function enables the room to be ventilated with outside air which is fresher than the return air. For this to happen, it
is necessary to bypass the exchanger.
The parameters to be entered are the start date (parameter
Pr12
,
Pr13
), the end date (parameter
Pr14
,
Pr15
), the
start time (parameter
Pr16
), the end time (parameter
Pr17
) and the fan speed (parameter
PF31
, speed V3 by default).
