15.1.3 Heat pump Settings continued
Max. rps on noise reduction 50
Max. rps on noise limitation. The compressor’s
maximum speed when noise limitation is active.
NB: You should note that the maximum output of
the heat pump will fall and the need to add heat may
increase.
Noise reduction Yes/No
It is possible to start a schedule with limited compressor
speed to reduce the sound image.
Heating<>DHW Switching time (sec.) 120
Time in seconds during which the compressor maintains
a constant speed while switching from the upper to the
lower tank (or from the lower to the upper tank)
Charge pump 50 (In progress, 25,100)
Charge pump speed in %. Automatic mode strives for
∆t 7ºC. If a value of 100 is reached and displayed in red
there is insufficient flow in the heat pump.
If a value of 25 is reached and displayed in red then ∆t
<7ºC.
The speed is set using “Auto setting charge pump”.
When the test is running, “In Progress” is displayed.
If a value is selected it becomes a fixed value and is
displayed in red.
The value is also displayed in red on installation as “Auto
setting charge pump” has not been run.
Auto setting charge pump
This function starts the calculation of the optimal charge
pump speed. The function is activated by marking
the “Auto setting charge pump” line and pressing
“OK”. While calculation is in progress, “In progress”
is displayed below the “Charge pump” line. Once
calculation is compete the new value is placed in the
“Charge pump” line, e.g. 72%
The calculation takes approx. 5 minutes. Do not touch
the screen while “In progress” is displayed.
Different operating modes and seasons may produce
differing results. Any calculation should therefore be
repeated after 4 weeks.
The CTC EcoZenith i250 is supplied with suitable factory settings for the CTC EcoAir 520M.
Enertech AB recommend these for optimal operating economy.
