23. Set the boiler controls to the required values.
24. Send the commissioning reports to Broag.

Note:
The Remeha Gas 610 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
module modulates on the basis of the flow tem-
perature, asked by the modulating control (see
'Note' in point 25c and section 8.6.2).
25.b High/low operation: The boiler module is oper-
ating at part load or full load, depending on the
heat demand (see section 8.6.5). On the safety
boundaries the boiler module is going to modu-
late.
25.c On/off operation: the boiler module modulates
between minimal and maximal output on the
basis of the flow temperature pre-set on the
boiler module (see section 8.6.4).

Important!!
The boiler module 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 sec-
tion 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,
3V = 30%, 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 module modulates on the basis of the set
flow temperature (setting range 20ºC to 90ºC) and a
maximum ∆T protection.
10.2 Shutdown
1. Switch off the operation switch of the boiler module.
With this, a possible boiler control will be without ten-
sion also.
2. Close the gas cocks.
g
Important!!
When a boiler module is out of
operation, it is not protected against frost!
