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. airow

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 airow 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
