6.2.7 Continuous running (low) speed
The unit will run at the speed set as indicated in table 6.2.1until the integral temperature sensor switches it to “Heat Recovery”
or “Summer Stand by” mode.
6.2.8 Maximum speed
The maximum speed can be activated by means of a remote dedicated switch (Fig.5.j) and can be set as shown in table 6.2.2.
6.2.9 Heat Recovery Mode
When the air in the loft is above a trigger temperature threshold the unit will automatically switch to an increased speed. The
trigger temperature threshold can be set using the dip switched as shown in table 6.2.4. It is usually adjusted to 1°C above the
temperature the home is heated to.
The increase of the speed can be set using the dip switch (see table 6.2.3).
For example: the low speed is set at 104m
3
/h and the intermediate speed is set in configuration 01 (i.e. +20%), when triggered
the intermediate speed will be 104-20,8=124,8m
3
/h.
6.2.10 Summer Stand-by Mode
When the air in the loft is above a trigger temperature threshold, the unit will switch off to prevent that undesirable warm air
being introduced unnecessarily in to the home. The trigger temperature threshold can be set using the dip switched as shown
in table 6.2.5.
6.2.11 Activation of the heating element
The unit is fitted with a heater that tempers incoming air when required. The desired temperature can be set using the dip
