Condensation fan control
<IMG INFO>
36,75
Condensation control is dependent on the condensation
temperature or pressure for the circuit.
Fan control will be on if:
at least one probe per circuit is configured as a
condensation probe (pressure or temperature);
if not, the fan for the circuit will come ON and go OFF
in response to the circuit
compressors
.
Fan control may be independent of the compressor, or
it may be carried out in response to requests from
HyperCodex152compressors;
Operating mode is determined by parameter
Pa F05
:
Value
0
1
Pa F05
:
If the compressor is off,
condensation control is
fan output mode
the fan is off
independent of the compressor
When the compressor is started up, if the proportional
control requests fan
cut-off
, the
cut-off
may be excluded
for an amount of time equal to
Pa F12
beginning when
the compressor is turned on. If the controller requests
cut-off
during this time period, the fan will run at
minimum speed.
If parameter
Pa F05
is set to 1, condensation control
will be dependent on condensation temperature or
pressure, depending on how the following
parameters
are set:
Silent speed :
The fan control unit may have a minimum speed, a
maximum speed, and a “silent” speed (for silent
operation, for instance during the night), as well as a
proportional band within these values.
The fan will always be off if:
there is an alarm indicating that a
condensation fan
has shut down (
refer to table of alarms
).
Energy 200 is on
stand-by
or off
CONDENSATION FAN CONTROL
IN COOL MODE :
Pa F06
= Minimum fan speed in COOL mode;
Pa F07
= Maximum silent fan speed in COOL mode
Pa F08
= Minimum fan speed temperature/pressure
set point
in COOL mode
Pa F09
= Fan prop. band in COOL mode
Pa F10
= Fan
cut-off
delta
Pa F11
=
Cut-off hysteresis
.
Pa F13
= Maximum fan speed in COOL mode
Pa F14
= Maximum fan speed temperature/pressure
set point
in COOL mode
An example of interaction of these
parameters
