to 0, the unit will run at the 3rd speed until a lower speed
has been selected manually.
18: Hour
If automatic stepdown at 3rd speed, is in use, the number
of hours at which the unit is to operate with forced
air, may be adjusted here. The set point may be adjusted
between 1 – 10 hours.
19: Suppl .heating (El. or water heated airflow)
By adjusting the set point to 0, the supplementary heat
will not cut in, even if there is a need for it. If the
set point is adjusted to 1, the supplementary heat will
cut in, as needed. This is controlled by the room sensor
in the control panel.
20: Solar col hyst
If a solar collector has been connected, a temperature
difference may be set, which must be between the
water temperature in the solar collector and the
operating thermostat of the hot water tank, before
the circulation pump of the solar collector is running.
When the set temperature of the operating thermostat
has been reached, the solar collector circulation
pump will not run, even if the temperature difference
is larger than the set value. The set point may be set
between 0 - 5°C.
21: Airflow 1 SUP
Level 1 is the lowest speed which may be used when
being out of the home, e.g. on holidays or weekends.
Both fans may be set independently at all levels, to
achieve the same air volume on the supply side as on the
extract side, thus giving optimum operation. Initial
adjustment of the unit must be performed with technical
air measurement equipment, and may be done without using
the main adjustment damper. Remember if the air volume is
set lower than the minimum air volume in point 16, the
heat pump will switch off. The provisional factory
setting is 40%.
22: Airflow 2 SUP
Level 2 is the normal operating speed for the unit,
providing the optimum internal climate and must be
regulated to the ventilation needs of the individual home.
The provisional factory setting is 70%.
12: Reduce sup. Air
If set point 1 has been selected under point 11, it is
recommended that the external temperature is set to -
10°C.The set point may be set between 0 - -15°C.
13: Airflow suppl.
It is recommended that the supply air volume is adjusted
to 20% lower than the set value in menu point 22.
14: Filter change
The control system contains an integral timer which
counts the time for which the unit has been in operation
since the last filter change. It is recommended that the
set point is initially set to 3, meaning three months. If the
filters are too dirty, the set point may be reduced. If it is
unnecessary to change the filters after three months,
the set point may be increased. The set point may be
adjusted between 1-6, equal to 1-6 months. When the
timer reaches the set value for filter change, the red
Genvex logo will begin to flash on the control panel and
the words “change filter” will appear on the display. The
Genvex logo will continue to flash until the filters are
changed. When the filters are changed the filter timer
can be reset by pressing ”enter ” in 10-15 sec. until the
Genvex logo begins to flash again and the equipment is
back in normal operation.
15: Hold ON-OFF
To avoid forgetting the change of filters allthough the
Genvex logo is flashing on the control panel, the set
point may be adjusted to 1. In this case, the unit will
automatically stop after 14 days, if the filters have not
been changed in the meantime. If this safety feature is
not desired, the set point may be adjusted to 0, and the
Genvex logo will keep on flashing until the filters are
changed.
16: Min. airflow
To achieve optimum operation of the unit, the unit air
volume must, as a minimum, conform to the values
described in the brochure dealing with the actual unit.
If the air volumes are set lower than the minimum
requirement, the heat pump will stop and only pre-heated
air will be blown from the heat exchanger into all rooms.
The minimum air volume is set by the initial adjustment
of the unit. The provisional factory setting, is meanwhile
30%.
17: Extended airflow
At 3rd speed, there is an option of making the unit step
down automatically to the 2nd speed, after a number of
hours, by adjusting to set 1. If the set point is adjusted
