Shutdown - REMEHA Gas 310 ECO Technical Information

17. h Remove measuring equipment and seal test
points.
18. Check gas leakage control and minimum gas
pressure switch (if installed):
Parameter J must be set to a value greater than or
equal to 8, depending on the connected options (see
section 13.2.13).
Then set the gas leakage control pressure switch to
a switch pressure equal to 50% of the inlet pressure.
Check that the measured inlet pressure is not the
(higher) closing pressure.
19. Return the boiler to 'user level' by pressing the
reset key.
20. Heat the system to approximately 80ºC and
switch off the boiler.
21. Bleed the system and check the water pressure.
22. The boiler is now ready for operation.
23. Set the boiler controls to the required values.
24. Send the commissioning reports to Broag.

Note:
The Remeha Gas 210 ECO is supplied with a number
of factory default settings that should be correct for most
installations. If other setting values are required: see
sections 13.1. and 13.2.
The following operating situations are now possible:
25.a Modulating operation: The output of the boiler
modulates on the basis of the flow temperature,
asked by the modulating control (see 'Note' in
point 25c and section 8.6.2).
25.b High/low operation: The boiler is operating
at part load or full load, depending on the heat
demand (see section 8.6.5). On the safety
boundaries the boiler is going to modulate.
25.c On/off operation: the boiler modulates between
minimal and maximal output on the basis of the
flow temperature pre-set on the boiler (see sec-
tion 8.6.4).
g
Important!!
The boiler will initially operate in
forced part load. The factory setting for forced part load
time is 30 seconds. This setting is correct if modulating
controllers are used (see point 25a). A forced part load
time of 3 minutes is recommended for on/off operation
(setting mode, parameter *, see section 13.2.3).
25.d 0-10 V operation: Depending on the adjust-
ments, two situations are possible
(see section 8.6.3):
- The given off output varies linear with the sent signal,
2V = 20%, 10V = 100%
- The given off flow temperature varies linear with the
sent signal (depending on parameters a and B);
example: 0V = 0°, 10V = 100°.
The boiler modulates on the basis of the set flow tem-
perature (setting range 20ºC to 90ºC) and a maximum
∆T protection.

10.2 Shutdown

1. Switch off the on/ off switch of the boiler. With this, a
possible boiler control will be without tension also.
2. Close the gas cock.
