Functions
5-1
Switch stand-
by heating
Stand-by heating is enabled or not (0= off, 1=on).
5-2
Interval
stand-by
heating
Parameter 5-2 determines the interval time between
heating phases when stand-by heating was
enabled.
5-3
On-time
Stand-by
heating
Parameter 5-3 sets the heating on-time when
stand-by heating was enabled.
5-4
Basic relay
allocation
The basic relay features potential-free NC and NO
contacts across terminals 28,29 and 29,30, respec-
tively (contact capacity is 250 VAC/8A).
The relay is activated when a certain operating sta-
tus is achieved. Parameter 5-4 allows for allocating
a logical function, i.e. the relay is energised when a
certain operating status occurs. Factory setting is
„0“ defined as „collective fault“
The following allocations are supported:
(0) Collective fault: Relay is energised in case of
any fault.
(1) Stand-by: Relay is energised when the unit is in
stand-by.
(2) No demand: Relay is energised when input sig-
nal creates no demand.
(3) Humidifying: Relay is energised when humidify-
ing is active.
(5) Remote off: Relay is energised when safety
interlock was opened under software by means of
the building control system.
(30) Filling off: Relay is energised when filling is not
active.
(31) Filling on: Relay is energised when filling.
