What to do if a fault occurs

Example of an alarm:

When an alarm is triggered, an alarm window is displayed and a warning signal 
sounds. The alarm window displays the alarm causes and the time and date that 
the alarm occurred.

When you press the menu dial, 

Acknowledge

 is marked, the alarm symbol goes 

out in the menu window and in the alarm log and the warning signal is muted. 
The heat pump starts again within 15 minutes if heating is required. If the fault 
has not been rectifi ed the lamp will remain lit and the status lamp will stop 
fl ashing red and will light red continuously. Should several alarms have occurred 
on the heat pump, view the alarm log where all alarms are counted. For active 
alarms, the alarm symbol lights.

Protective anode

At the top of the hot water cylinder, under the insulation, there is an electronic 
protective anode. Its purpose is to prevent corrosion. The cylinder must be fi lled 
with water for the anode to work. There is a LED in the electric box that shows 
a red or a green light. If green, the protective anode is operating and working 
normally. 
Should large amounts of hot water be drawn off (when fi lling a bath for instance) 
the diode lamp may show a red light for a short time even though there is no 
fault. If the lamp shows red for more than 10 hours, the anode is faulty and a 
service engineer must be called. You can wait until the next working day if the 
fault occurs on a holiday.

Overheat protection electric element

The button for resetting the electric element overheat protection is on the front 
of the electric box. This is a protection device that should normally not trip. If, 
however, it does trip, reset it by pressing in the button fi rmly. If the overheat 
protection device trips frequently, call a service engineer to establish the cause.

Emergency operation

There is a switch on the top of the electric box that shows a green light in 
normal operation. If a fault occurs in the control unit and heat production stops, 
emergency operation can be activated manually using the switch, which then 
goes out. Emergency operation can also be activated automatically (and then the 
switch continues to be lit).

The additional heat takes over the heat production during emergency operation. 
Heating can therefore be obtained until the dealer or authorised service techni-
cian has remedied the fault.

This function must not be confused with Alarm mode, which means that the com-
pressor stops, for safety, due to an active alarm. Heat production is still controlled 
by the control unit.

Maintenance

The control unit has an advanced monitoring system that gives alarms if anything unforeseen happens in 
the system. Most alarms correct themselves. There is never a risk of affecting something when you reset 
an alarm once or twice. In the event of recurring alarms, contact your dealership/service technician. 

This is described further in the Optima guide and also describes what actions you can take.
