9.6.2 Pre-/Reheating
AIR HEATER FOR HOT WATER
On selecting the exercising pump or pump+valve function,
the selected relay output will be activated if reheating
is needed and this starts the circulation pump of the air
heater.
If the outdoor temperature is low (colder than +12 °C),
the pump output contact is continuously activated. During
other times, the pump output contact is activated 2
min/24 hours for exercising of circulation pump.
ELECTRIC AIR HEATER
If “pump exercising mode inactive” has been selected, the
relay output is activated whenever heating is required.
The relay output can be used for indicating or blocking the
external function.

9.6.3 Heating BOOST
Heating boost means that the air handling unit, operating
in the normal flow regulation mode, increases both the
supply airflow and the extract airflow in order to carry
more heat into the premises.
The fans are allowed to work in the range between cur-
rent flows (low speed, high speed) and preset max speed
flow.
The function only works if the air handling unit is opera-
ting in the extract air regulation mode. If demand control
or boost is selected in combination with heating boost,
the flow is controlled by the function that transmits the
highest output signal to the fans.
This function cannot be combined with pressure regula-
tion.
A regulated ramp function begins and increases the air-
flow if the temperature exceeds its setpoint and it differs
2-10°C (3°C has been factory preset) to the preset max.
supply air temperature. The control reaction speed (ramp
time = % flow increase/minute) can be set. The highest
possible airflow is limited by the max. flow. For particulars
on setting the max. flow, see Section 7.2.
