11.9 First start-up of the regulator
The regulator should be programmed to
cooperate with the given type of boiler and
central heating system.
Preparation for cooperation with the boiler:

Set the value of service parameter
minimal fan revolutions n2 in accordance
with point 12.3,

Preset minimum boiler temperature n3 in
accordance with point 12.4.

Preset maximum boiler temperature n4 in
accordance with point 12.15.

Select method of detecting fuel shortage
in accordance with point 12.21 and
12.10.

Select boiler regulation mode in
accordance with point 7.7
For
boiler regulation mode – 1 : select
value of parameters Maximum
revolutions and Minimum revolutions
, as well as value of the n7 parameter
as specified in point 12.8
For
boiler regulation mode = 2 and 3
(PID and PID - EMISSION): select value
of Maximum revolutions and
Minimum revolutions ..

Set the fan starting time P5, especially in
the case of fine coal boilers, as specified
in point 13.
Preparation for cooperation with central
heating system:

Set central heating pump activation
temperature, defined by parameter n0,
as specified in point 12.1,

If the hot utility water tank is to be filled
via hot utility water pump, select the hot
utility water pump operation mode, acc.
to point 7.9.
11.10 Connecting room thermostat
To make the boiler more economical, and the
temperature in the heated rooms more
stable, install a room thermostat.
The regulator is compatible with a
mechanical or electronic room thermostat,
which disconnects its contact after a preset
temperature
has been reached. The
thermostat should be connected in
accordance with Drawing 12.
After installing a room thermostat, you must
enable its support. To do so, set the service
parameter
Room thermostat (service
parameter n8 = 1).
After reaching the preset
temperature in the room, the room
thermostat disconnects its contacts,
and a symbol appears on the display
(symbol 7, Drawing 2)
When the temperature in the room in which
the room thermostat has been installed
reaches the preset value (the room
thermostat disconnects its contacts), then:
a) the ecoMAX 200 regulator lowers the
preset boiler temperature by the
value
Boiler preset temperature
decrease by thermostat (service
parameter r0), which is signalled by
symbol 10, Drawing 2.
b) the ecoMAX 200 regulator will block
the central heating pump for 30 s at
intervals
Central heating pump down-
time by thermostat (service
parameter n8). If n8 = 0, there is no
central heating pump blockade.
It is not recommended to block
the central heating pump if the
PID mode of regulation is
selected, in such case it suffices to
lower
the boiler preset
temperature. The regulator will
automatically
reduce its
revolutions.
Central heating pump blockade by
thermostat can be enabled only
after making sure that the boiler
will not overheat.
