Nibe F2030, Руководство по установке

Страница: 25 / 56

Preparations
■
Ensure that the heat pump cannot be damaged
during transport.
■
Before commissioning, check that the heating circuit
is filled and well vented.
■
Check the pipe system for leaks.
Filling and venting the heating
medium system
1. The heating medium system is filled with water to
the required pressure.
2. Vent the system using the venting nipple on the
enclosed flexible pipe and possibly the circulation
pump.

Balance temperature
The balance temperature is the outdoor temperature
when the heat pump’s stated output is equal to the
building’s output requirement. This means that the
heat pump covers the whole building’s output require-
ment down to this temperature.
Set the balance temperature, additional heat, in chan-
nel A5.
Stop temperature
When the stop temperature (channel A7) is set
between -10 and -25 C the flow temperature is limited
linearly from -10 C / 65 °C to -25 °C / 63 °C (see diagram
on page 42).
If the ambient temperature is below the set value for
stop temperature heating must occur using the addi-
tional heat.
Soft-starter
F2030 is equipped with a soft-start (AA10) that limits
the inrush current for the compressor.
Compressor heater
F2030 is equipped with a compressor heater that heats
the compressor before start-up and when the com-
pressor is cold.
NOTE
The compressor heater must have been con-
nected for 6 – 8 hours before the first start, see
the section "Start-up and inspection".
Collar heater
F2030 is equipped with a collar heater that can heat
the fan collar if necessary (not activated upon delivery).
NOTE
The collar heater is only required in certain
cases where the ambient temperature is too
low for a long period.
Phase sequence control
BA1
The phase sequence sensor (BA1) starts as soon as the
power supply is connected to the heat pump. Check
the phase sequence as shown below.
■
Red LED is lit at correct phase sequence
■
If there is a fault in the phase sequence, the heat
pump receives an alarm 07 in channel S1 and the
LED flashes.
NOTE
Check the phase sequence when starting!
