Activate demand-controlled operation if you want to control the quality of the room air
automatically. In this mode, the measured values of the VOC, RH and/or CO
to control the quality of the room air. Therefore, the respective sensors must be connected for
demand-controlled operation. The CO
Accessory Controller (HAC).
Pressing and holding (five seconds) the Week/Auto button activates demand-controlled
operation. When demand-controlled operation is activated, this will be indicated by the
corresponding LED flashing slowly.
With the exception of the automatic bypass function, the temporary operating modes are
activated manually and temporarily override the settings of the selected main mode. The
temporary operating modes are stopped automatically by a timer or if certain conditions are
not met, but can also be deactivated manually (with the exception of the automatic bypass
function).
In bypass mode, the bypass damper is opened, which will guide the airflow around the heat
exchanger. The outdoor air is thus guided into the dwelling without heat recovery. The bypass
mode can be activated in two ways:
• Automatic bypass function
• Manual bypass function
When using the automatic bypass function, the bypass damper is automatically opened/
closed when the conditions for automatic bypass are met.
You can change the setpoints for the minimum outdoor temperature (Tmin, default setting:
15 °C) and max. indoor temperature (Tmax, default setting: 24 °C) via the PC Tool or the
Dantherm HRC3 remote control.
If the conditions for automatic bypass are met, the open status of the damper is indicated by
the continuous illumination of the corresponding LED.
Conditions for activating the automatic bypass function:
• The outdoor temperature is at least 2 °C below the extract air temperature
• AND the outdoor temperature is above the setpoint (Tmin)
• AND the extract air temperature is above the setpoint (Tmax).
If one of the following conditions are met, the bypass is deactivated:
• The outdoor temperature is above the extract air temperature.
• The outdoor temperature is at least 2 °C below the setpoint (Tmin).
• The extract air temperature is at least 1 °C below the setpoint (Tmax).
NOTICE
Waste of energy!
If the settings for the bypass temperature are too low, there is a risk that the unit will open the
bypass while the central heating inside the dwelling is active.
