Commissioning the heat pump
Timer readings
There are a number of different menu displays to help you check the status
of the heat pump. The heat pump status is shown by the timer readings in
menu 6.
Reading the DHW peak timer
The function shows the status of when the next hot water peak will be
carried out. If the timer shows zero the hot water peak will be activated the
next time there is a hot water requirement.
Read the additional heat timer
The function shows the amount of time remaining before the additional
heat is activated. If there is no countdown then there is no need of ad-
ditional heat.
Reading the alarm timer
The function gives you information about an alarm. If the heat pump has
stopped, a countdown starts from 60 minutes (3600 seconds). When the
time has elapsed and the alarm has not been rectifi ed, the additional heat
starts so that the house will not be cold and to produce hot water.
Read the start delay
The function shows the time remaining until the heat pump starts again
after a previous stoppage. The heat pump will not start if there is no
heating or hot water need.
Setting the additional heat
Add. heat timer
The function gives you the possibility to set the time that should elapse
before the additional heat starts if the heat pump cannot produce suffi cient
heat on its own. On delivery the heat pump is set to one hour.
Ramp time open
Here you set the time that you would like the immersion heater to go from
0 to 100%. In some cases the ramp time open, may need to be adjusted to
eliminate overexciting the system.
Ramp time close
Here you set the time that you would like the immersion heater to go from
100 to 0%.
Show connected elec. capacity
