Winter mode (CH)
When the control panel is switched to „Winter mode” the
icon is on. In this time
the control panel is in the main view display, the icons show current working mode of
boiler. The digital display shows the temperature of medium (for central heating). You
can check out the following working parameters by pressing the
button. A display
shows (in sequence): CH medium temp. setting (D and M indicators are on), inlet
temp. (D and K indicators are on), outlet temp. (D and L indicators are on), medium
flow rate through the boiler (B indicator is on), installation pressure (A indicator is on),
power with which the boiler currently heats (C indicator is on).
To set the temp. of medium press
or
(when you are in medium temp. setting
view). The temp. can be set between 20 – 85
0
C. A controller will switch over to the
main view, if you don’t use a buttons for 1 min. To automatically switch to the main
view press
(when you are in the medium temp. setting view).
To ensure smooth and economic boiler operation, the temperature of the medium (for
central heating) has to be set in accordance with current weather conditions (outdoor
temperature), taking into account the building parameters (e.g. compactness, insula-
tion, windowing etc.). Optimum settings of the medium temperature can reduce the
boiler operating costs.
Winter mode (CH + DHW) - EKCO.LN2 and EKCO.L2 only.
In this mode the three-way valve directs the medium to either central heating instal-
lation or cylinder coil. The priority is to heat the DWH cylinder, at the same time the
central heating system is off.
When
and
. icons are on it shows that the boiler is in C.H + DHW mode.
When you switch to this mode the control panel is in the main view display, an icons
show current working mode. The digital display shows the temperature of medium.
You can read and set the following working parameters by pressing the
button. A
display shows (in sequence): CH medium temp. setting (D and M indicators are on),
DHW temp. reading and setting (D and N indicators are on) or an exterior thermostat
status (N indicator is on), inlet temp. (D and K indicators are on), outlet temp. (D and
L indicators are on), medium flow rate through the boiler (B indicator is on), pressure
in the system (A indicator is on), power with which the boiler currently heats (C indica-
tor is on). A water temp. in cylinder is shown only if the WE-019/01 temp. sensor is
applied to the Tzas entry. To set the temp. of DHW press
or
button (when you
are in cylinder temp. setting view). The temp. can be set between 30 – 80°C (D,N,F
indicators are on). If you set temp. at 0°C it will switch off the DHW cylinder heating
(
indicator flickers). When an external thermostat is applied (instead of temp. sensor)
the contact status will be shown (instead of water temp.): 0 – open contact, 1- close
contact. The close-open contact of thermostat has to be connected to the Tzas entry
(see figure on page 6). A boiler heats the cylinder when the Tzas entry is closed. You
can activate or deactivate cylinder heating mode by pressing
or
button when
you read the thermostat contact status, 0- DHW mode is deactivated, 1 – DHW mode
is activated. The
icon flickers when you deactivate cylinder heating mode. To set
the temp. of medium press
or
(when you are in medium temp. setting view).
