Meaning
Start temperature for hot water production. Shows the actual
weighted hot water temperature and the value within brackets
indicates the start temperature. (
Time for hot water production during combined hot water and
heating demand, in minutes.
Time for hot water production during combined heating and hot
water demand, in minutes.
Time interval between peak heating charging, anti-legionella function,
in days. Operating mode that permits auxiliary heater must be selected.
Stop temperature for peak heat charging. Operating mode that
permits auxiliary heater must be selected.
Water heater sensor's influence compared with the peak sensor's
at start of water heating.
The calculated value of the hot water sensor directed towards
the peak sensor.
Meaning
The integral's value for starting the heat pump. See figure in sec-
tion 11.5 Important parameters for further information.
If the difference between the actual supply temperature and the
calculated supply temperature is too great either the integral
value is set to start value A1 (the heat pump starts) or the value
is set to 0 (stops the heat pump).
Stop temperature at high return from the heating system.
Minimum tine interval between two heat pump starts in minu-
tes.
Sensor on the compressor's pressure pipe line. Value within brack-
ets indicates maximum permitted temperature. If this value is
exceeded, the compressor will stop and start again as soon as the
temperature has dropped. No alarm shown in the display, however,
a square is shown in the left, lower corner of the display.
Only appears if AIR is selected. Lowest outdoor temperature
when the outdoor sensor stops the compressor and heating or
hot water instead produce with auxiliary heater. Operating mode
that permits auxiliary heater must be selected.
Meaning
Maximum number of permitted steps for auxiliary heating.
= no auxiliary heater permitted (Means that only operating
modes AUTO, HEAT PUMP or
legionella operation is not possible.)
Two conditions must be fulfilled in order to start the auxiliary
heater: the integral's value to start must be less than integral A1
+ A2, and the supply temperature must be 2° lower than the cal-
culated temperature. See section 11.5 Important parameters for
further information.
