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 in hours that the legionella demand is to be fulfilled for
legionella operation to be considered complete.
Time for hot water production during combined heating and hot
water demand, in minutes.
Time interval between peak heating chargings (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 Important
parameters for more 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 time interval between two heat pump starts in
minutes.
Gives an alarm when the outgoing brine temperature falls
below the set value.
Sensor on the compressor's hot gas line. The 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 dis-
play.
Displayed only if AIR is selected. Lowest outdoor temperature
when the outdoor sensor stops the compressor and heating or
hot water are instead produced by the auxiliary heater.
