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
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
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
E21: TX set
In order to avoid high operating pressures in the cooling system, the system
output 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
prevents overloading of the compressor system at high ambient
temperatures.
Adjust this value between 0-25°C.
Factory setting: 25
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
