REMKO RVS 60 H - Manual (Page 34)

■
Observe the manuals for the
system and all other compo-
nents when commissioning the
entire system.
Commissioning should only be
Carried out by trained person-
nel and after certification to be
documented.
NOTE
Commissioning
Working test for cooling
mode
1. Switch the power supply on.
2. Open all shut-off valves if
necessary.
3. Switch the system and the cor-
responding circulating pump on
to the highest stage.
The outlet temperature must lie
between +4 and +18°C.
4. Switch the unit on and select
the cooling operating mode.
If the return temperature is
warmer than the setting, the
compressor display will blink
and the compressor will begin
to work after approx. 3 to 5
minutes.
5. Please note that the supply
temperature at the nominal
medium flow lies approx. 5 K
below the return temperature.
- If the supply temperature falls
below the factory setting of
4°C, a fault signal is triggers. If
this is the case, a higher target
temperature must be selected.
If the spread is too great or too
small, the medium flow must
be checked.
- The circulation pump starts
and the controller checks the
medium flow over the flow
switch.
If the flow is insufficient, a
fault shut-down will be carried
out and the cooling cycle will
not work.
6. Measure and record all the
required values in the commis-
sioning report and check the
safety functions.
7. Check the system control using
the functions described in the
"Operation" chapter.
Working test for heating
mode
(only units with HP-function)
1. Switch the power supply on.
2. Open all shut-off valves if nec-
essary.
3. Switch the chilled water system
and the corresponding circulat-
ing pump to the highest stage.
The outlet temperature must lie
between +35 and +45°C.
4. Switch the unit on and select
the heating operating mode.
If the return temperature is
colder than the setting, the
compressor display will blink
and the compressor will begin
to work after approx. 3 min-
utes.
5. Please note that the supply
temperature at the nominal
medium flow lies approx. 5 K
above the intake temperature.
- The circulation pump starts
and the controller checks the
medium flow over the flow
switch.
If the flow is insufficient, a
fault shut-down will be carried
out and the cooling cycle will
not work.
6. Measure and record all the
required values in the commis-
sioning report and check the
safety functions.
7. Check the system control using
the functions described in the
"Operation" chapter.
Final tasks
■ Reassemble all disassembled
parts.
■ Familiarise the operator with
the system.
The system is delivered from
the factory with all parameters
set.
If during commissioning it is
necessary to change a param-
eter it can only be done by
authorised personnel.
NOTE
During the initialization of the
controller (after starting the
unit and displaying the soft-
ware version, e.g. “H 99”) do
not push the key-pad “Prg”
to avoid reprogramming the
controller!
