Nibe BA-SVM 10-200 User Manual

23NIBE BA-SVM 10-200
For the heat pump to disconnect the electrical output
in the correct phase, the phase sequence must have
been detected during the installation. In the menu
5.1.12 the phase sequence must be detected after-
wards. An unsuccessful detection may be due to the
current sensors not being correctly connected or that
other electrical equipment started or stopped during
detection.
Menu Name Factory setting
5.1.12 fuse size 16A
1-phase inverter stepping out:
Variant of load monitor designed to be used in in-
stances where 1-phase inverters are used.
Compressors together with 3-phase disconnectable
additional heat:
Load monitor initially disconnects the immersion heat-
er’s output. Finally the heat pump frequency is reduced.
If this phase is used to drive 1-phase inverter com-
pressor:
Initially, the step-controlled additional heat is discon-
nected from this phase as per the section above regard-
ing disconnecting the step-controlled additional heat.
If the electrical power still exceeds the set value the
compressor slows to 20 Hz per 30 seconds until the
electrical power falls below the set value.
External connection options
AUX inputs
There are 5 x external inputs with selectable function.
Connected on AA3-X6:9-18.
The selectable functions are activated in menu 5.4.
Selectable functions that are active when the input is
connected:
AUX1-5
• Not used.
• Activate temporary lux
• External adjustment
• Block additional heat
• Blocking Compressor
• Block heating
• Block cooling
• Cooling/heat sensor (BT74)
• Tariff blocking
• SG ready A
• SG ready B
• External alarm (NC)
• External alarm (NO)
• +Adjust
NOTE
BA-SVM 10-200 must be filled with water before the
phase sequence is detected.
AUX outputs
The selectable functions on the AUX output AA3 -X7
(max 2 A) are activated in menu 5.4:
AA3-X7
• Not used
• Add heat in series
• Alarm output
• Cooling mode indication
• Hot water circulation
• Ext. heating medium pump
Extra additional heat in charge circuit
Controls (via the AUX output, terminal X7) additional
heat which is in series between heat pump and BA-
SVM 10-200. The additional heat controls in one step
and is intended to support the installation when the
heat pump is stationary.
The additional heat must be dimensioned so that it is
in proportion to the installed heat pump. Because the
additional heat output is not known and an output is
required for the pump regulator, 7,5 kW is assumed.
If ”add heat in series” is selected on the AUX output
and the degree minutes are less than the selected
value in menu 4.9.3 ”start compressor”, the AUX re-
lay opens during the following:
• Red light alarm from heat pump
• Communication alarm from heat pump.
• Cold outdoor air, heat pump.
• Only additional heat selected in menu 4.2.
The AUX relay must be off if the degree minutes are
greater or equal to 0 DM.
When the AUX relay is on, charge pump GP12 must
run:
• If the speed is set to ”manual speed” in menu
5.11.1.2, GP12 is run according to the menu set-
tings.
• If the speed is not set to ”manual speed” in menu
5.11.1.2, GP12 runs and calculates that the addi-
tional heat in the charge circuit produces 7,5 kW.
GP12 runs as if the internal additional heat is on.
