11.1.2 LED indicators
Each instrument panel has 4 indicating LED's with the
following functions:
- The LED above the [-] key (in the h symbol); when
illuminated green confirms the boiler module is in
manual override (see section 11.2).
- The LED above the [e] key indicates that "24 hour
pump operation" has activated the heating pump (and
the shunt pump if required).
- The LED above the [+] key flashes if the optional
hydraulic pressure sensor detects that the water pres-
sure is too low.
- The LED above the [s] key flashes if there is no
communication with the code key (code key not con-
nected).
- Two LED's flash green when there is no communi-
cation anymore between code key and control unit.
The boiler module will keep on operating. Only after
the power supply was switched off and back on, the
boiler module will refuse to operate.
11.2 Switch function keys
Some keys on the instrument panels have dual func-
tions, i.e. a programming and a switch function.
The programming function is described in section 13.
The switch function (on or off) is activated by pressing
down the relevant key for 2 seconds. Whether the func-
tion is switched on or off is indicated by the indicator for
the key, which is either lit or not lit, or by the appearance
of a letter in the code window.
11.2.1 Manual/automatic operation
If the [-] key is pressed for 2 seconds the boiler module
will switch on, even if there is no heat demand from an
external control. The green LED above the key is on
continuously to indicate manual heat demand (central
heating bridged internally). When the [-] key is pressed
for 2 seconds again the boiler module will return to auto-
matic central heating operation (green LED off).
i
During manual operation the flow temperature
cannot exceed its pre-set maximum value. This is to
protect the boiler module and the system. Parameters
can be changed during manual operation.

Important!!
If an external heating pump is
not connected to the control unit, the pump will not be
switched.
11.2.2 Forced mode 'high' (h [[)
By pressing the m and [+]-key simultaneously in operat-
ing mode during 2 seconds, the boiler module will run at
maximum power. The letter h will now appear on the
display. To protect the boiler module and the system, the
flow temperature cannot exceed its pre-set maximum
value. This is. Parameters can be changed in this mode.
By pressing the [+]- and [-]-keys simultaneously, the
boiler module will return to operating mode.
Remeha Gas 610 ECO
Following a manual override the boiler module will return
to normal (auto control) if no keys are used within a 15-
minute period.
11.2.3 Forced mode 'low' (l [[)
By pressing the m and [-]-key simultaneously in operat-
ing mode, the boiler module will run at minimum power.
The letter l will now appear on the display. To protect
the boiler module and the system, the flow temperature
cannot exceed its pre-set maximum value. Parameters
can be changed in this mode. By pressing the [+]- and
[-]-keys simultaneously, the boiler module will return to
operating mode.
Following a manual override the boiler module will return
to normal (auto control) if no keys are used within a 15-
minute period.
11.3 Display of values
The display has only two digits available therefore val-
ues over this are displayed as follows:
- values from 00 to 99 will be indicated without any
punctuation marks
- values from 100 to 199 will be indicated by a dot
between both digits e.g. )0 = 100, !0 = 110,
(9 = 199
- values from 200 to 299 will be indicated by a dot
behind every digit e.g. )) = for 200, !) = 210,
(( = 299
- values over 300 will be indicated by showing the
thousands, hundreds, tens and units in separate alter-
nating pairs. (see section 12.2 and 12.5)
- negative values (for instance when using an external
sensor or when sensors are not connected) will be
indicated by a dot behind the last digit, e.g.
indicates -10.
