E17: Extended airow ON
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 setpoint is
adjusted to 0, the unit will run at the 3rd speed until a lower speed has been
selected manually.
Factory setting: 0
E18: Hour
If automatic step-down 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 setpoint may be
adjusted between 1 - 10 hours.
Factory setting: 3
E19: Extra function
If the setpoint is 1 the extra function will be activated as soon as T9 reach the
setpoint (se E2). If the setpoint is 0, the function will be out of order.
E21: TX set
In order to avoid high operating pressures in the cooling system, the system out-
put must be reduced for the remaining part of the heating period. This parameter
indicates the water temperature at which the reduction should start. It may be set
to 0-55°C.
Factory setting: 50
E23: Tmop
This value indicates the maximum permitted evaporation temperature. This pre-
vents overloading of the compressor system at high ambient
temperatures.
Adjust this value between 0-25°C.
Factory setting: 25
E25: Vent level 2
If an extended period of extraction from the building is wanted, it is possible to
change to level 2. The fan will now run until another level has been selected.
This option is used to set the speed at which the fan should run, when level 2 is
selected. Please note that this setting also sets the maximum fan speed when
running in level 1. The speed may be set to 0-100%.
Factory setting: 100
E26: Vent level 3
If extraction from the building at a specic length of time is required, it is possible
to change to level 3. The fan will now run for the set period. Thereafter the sys-
tem will return to level 2. This menu option is used to specify the speed at which
the fans should run when the set period has been chosen. Please note that this
setting also sets the maximum fan speed when running in level 1 The speed may
be set to 0-100%.
Factory setting: 100%
E27:
Available function. Must at all times be 1.
E45: dTair-set
Here it is possible to choose minimum cooling of the air, while heating the water.
The control will adjust the speed of the fan to make sure the air will be cooled at
the exact temperature chosen. In case the control needs to cool the air due to
technical reasons, the value will be controlled by the automatic function. When
requiring a higher fan speed, the value may be reduced. Remember though, the-
fan will run faster, using more energy, if the values are set to low.
Factory setting: 1
