1.3 Operating menu
E0: Factory default
If the system does not function as expected, even though the set points have
been adjusted, and the cause is impossible to locate, it is
recommended to note down the settings in the schedule. Thereafter the set point
must be adjusted to 1 and wait until the control returns to standard settings. Now
all the set points have been changed to the factory default. It is now possible to
start all over and adjust the set points.
Factory setting: 0
E2: T9 set temperature
This sensor is able to control the relay R9, which will be activated when the set-
point E2 is reached. The R9 relay can be used to control the three way damper
of the exhaust air. This three way damper can supply the living area with cool air,
if the room temperature reach the setpoint E2. For this function you will need a
separate sensor, which is not a within the standard delivering. The sensor shall
be connected to the control panel. For access to the control panel you have to
dismantle the top of the machine.
E2 can be set between 10-30°C
Factory setting: 21°C
E8: Disinfection function ON/OFF
By setting the point to 1, the electric cartridge will provide 65°C hot water, once a
week, in order to disinfect the tank (legionella protection function).
Factory setting: 0
E9: Operating in cold surroundings ON/OFF
If the setting is 0, the heat pump will run as long as there is a need of heat (=
exhaust air-operation).
Using the heat pump when taking the admission air from e.g. the cellar, there
is an option of making the compressor stop in case the room is getting to cold.
Instead, the electric heater will heat the water. The function is activated when the
value has been set to 1 (= circulating air-operation).
It is also possible to automatically let the electrical heater help heating the water
when the intake air temperature is below the temperature set in E10. The function
is activated when the value has been set to 2 (= fresh air operation). If the value
is 0, the function is not active.
Factory setting: 0
E10: Operating in cold surroundings
When activating the function menu E9, the temperature at which the compres-
sor will stop, or the heater will assist, may be set. The temperature is adjustable
between –10 and +10°C.
Factory setting: -5
E15: Hygrostat / stop unit
If the value is 0, the speed of the fans will change to 3 when the relative humidity
is above the preset value of the hygrostat. If the value is 1, the unit will stop when
the clips 25 and 26 are short-circuiting.
Factory setting: 0
E16: Min. airow
This value shows the minimum speed at which the fan is permitted to run when
operating. Notice that the cooling system may be overloaded,
resulting a drop out of the high-pressure switch, if the value has been set too
high. The value should not be chosen higher than necessary, in order to secure a
minimal airow through the cooling coil. Adjust this value between 0-100%.
Factory setting: 0
