Reheating; Heating Boost - Swegon GOLD PX Series Operation And Maintenance Instructions

8.5.2 Reheating

aIR HeateR FOR HOt WateR
If the "pump or pump + valve" exercising mode is
selected, the relay output is activated (control unit termi-
nals 5 and 6) whenever heating is required 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 (control unit terminals 5 and 6)
whenever heating is required.
The relay output can be used for indicating or blocking the
external function.

8.5.3 Heating BOOSt

Heating boost means that the air handling unit, operat-
ing 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 operat-
ing 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.
The flow increase starts steplessly when there is a differ-
ence of 2-10°C (3°C is factory preset) to preset max supply
air temperature. When max supply air temperature has
been reached, the unit runs at preset max flow (For par-
ticulars of how to set the max flow, see Section 6.3.2).
