Programming
After expiry of the "Minimum standstill period", the heat pump is
restarted.
When the flow monitor is again triggered during the "Duration fault
repeat", the heat pump is switched to fault mode and can only be
re-operated after unlocking.
- Flow monitor source E15: Accepts the signal of a flow monitor of
the source. The source pump is switched off when the contact
closes for at least the delay set (2895) while the source pump is
running and the predefined monitoring (always or only during
heating mode) is active and the lead time has expired.
After expiry of the "Minimum standstill period", the heat pump is
restarted.
When the flow monitor is again triggered during the "Duration fault
repeat", the heat pump is switched to fault mode.
- Flow monitor consumer E24: Accepts the signal of a flow monitor of
the consumer. The flow monitor is only works with the condenser
pump. The compressor does not start when the monitor signal is
pending after the lead time and the delay set (2895) have expired.
After expiry of the "Minimum standstill period", the heat pump is
restarted.
When the flow monitor is again triggered during the "Duration fault
repeat", the heat pump is switched to fault mode.
It can only be re-operated after unlocking.
- Defrosting, manual E17: Activation of the appropriately defined Ex
input triggers manual defrosting of the heat pump.
- Collective fault WP E20: Accepts a collective fault and sets the heat
pump to fault mode. The collective fault must be removed and the
"Minimum standstill period" (2843) must have expired in order to re-
start the heat pump.
- Fault soft starter E25: Accepts fault messages of the compressor
soft starter. When a fault is pending, the controller switches off the
compressor. When the fault message is removed, the heat pump is
again released. For WGB 2N permanently set to EX5.
- Low pressure monitor E9: Input of a low pressure controller. For
AMBIFLO permanently set to EX6.
- High pressure monitor E10: Input of a high pressure controller. For
AMBIFLO permanently set to EX7.
- Overload Compressor 1 E11: Input of an overload protection signal
(230 V) at the compressor.
Fault/alarm message: Input of an external fault/alarm signal (230 V).
Effect of input EX3
(5985)
This function determines whether the input works with normally-
closed or normally-open signals.
