45: Water reg sec (Water heated supply air)
If a water after-heating coil has been installed in the
supply air duct, it may be necessary to change the
regulator time, which has a standard setting of 20
seconds. The regulator time may be adjusted between 1
– 250 seconds.
46: Heating reg min (Electrical heated supply air)
If an electric pre-heating or electric after-heating
coil has been installed, it may be necessary to change
the regulator time, which has a standard setting of 3
minutes. The regulator time can be adjusted between 1 -30
minutes.
47: Print vers.
Here it is possible to se the vers.number of the operating
system
48: Not in use
The set point must be adjusted to 0.0
49: Not in use
The set point must be adjusted to 0.0
50: Stop defrosting
As standard, the defrosting period will stop when the
cooling surface has reached a temperature of 5°C, which
is the standard setting. In particular operating stages,
it may be necessary to change this temperature. The
temperature may be set between 0 - 10°C.
51: Temp dif.
As standard the temperature difference between start-
stop compressor is ±0,4°. Under special conditions,
it will be an advantage to change the temperature
difference. The difference may be set between 0,1-1,0°.
52: R9 function
This relay may be used as follows:
If the setting is 0, the relay is off.
If the setting is 1, the relay is on when the unit runs.
If the set point is 2, the relay is on when additional
heating is needed.
If the set point is 3, the relay is on when the lters
need to be changed.
If the set point is 4, the relay is on when extra
cooling is required.
If the set point is 5, the relay is on when T9 < the
lower set temperature in point 42, or when T9 > actual
temperature +1° and the adjusted temperature in point 2
+ 1°. Is used to control if the fresh air is obtained
through the ground collector or directly from the
outside.
38: Default values
Please notice: Before resetting the values please
ensure that the actual set points are noted in the
scheme page 43.
Here is an option for re-adjusting the set points to default,
in case the unit will not meet the requirements and
the cause is impossible to locate. Note all set points in
the schedule. Adjust the set point to 1 and press OK.
Hereafter all set points will be adjusted to factory default,
except the fan speeds and contrast settings.
To reset all to factory settings adjust the set point to 2 and
press OK. It is now possible to start all over and adjust
the set points. Remember to adjust fan speeds at Level 1,
2 and 3 as previous, as these are the numbers to which
the unit was initially adjusted.
39: Air +ON
In factory setting the heating priority is water tank rst. If
it is desired to heat the room before heating water, the
setting must be changed to 1.
40: Not in use
The set point must be adjusted to 0.0
41: Desinfection function ON/OFF
By setting the point to 1, the electrical heating element
will increase the water temperature to 65°C, once a week,
in order to desinfect the tank.
42: R9 Groundc temp
If a ground collector is connected to the equipment and
menu 52 point 5 is ON, it is possible to regulate, what
lower temperature the ground collector should be in
operation.
Setpoint can be set between 0° - 10° C.
43: T2 adjustment
It is possible to adjust the room sensor on the control
panel so that the display shows the correct room
temperature. The temperature may be set between -5
- 0°C.
44: Program info
The set point is always 0. If you press OK; the display will
show the installed program version for the heat pump. At
the same time, an automatic exit will be made from the
operating menu.
