The control panel consists of two working areas: the signalling area (elements: A-K) and
control area (L). The user can select the following working modes:
- stand-by,
- winter (CH or CH + DHW heating),
- summer (DHW heating),
Stand-by mode
To set the stand-by mode press and keep button for 2 seconds. Important: Do not
cut power supply off between heating season. When the control panel is switched to
„Stand-by” mode the control panel is off. In this mode the pump is activated every day
for 15 minutes (what protects the boiler and the whole central heating installation from
being blocked and silted up). The pump will run every day at the same time, it will be the
time of the day when you switch it to the „Stand-by” mode e.g. if you set the pump on
a „Stand-by” mode at 6 p.m. the timer will activate the pump everyday for 15 minutes
starting at around 6 p.m.
Winter mode (CH or CH + DHW heating)
To set the winter mode press , (when you switch from „stand-by” to „winter” mode).
The digital display shows the CH medium temperature. Indicator F is on when the
controller is in the CH medium temp. setting mode. To set the temp. of CH medium
value press or . The temp. can be set between 40 – 85oC. To ensure smooth and
economic boiler operation, the temperature of the medium has to be set in accordance
with current weather conditions (outdoor temperature), taking into account the building
parameters (e.g. compactness, insulation, windowing etc.). Optimum settings of the
medium temperature can reduce the boiler operating costs.
When the boiler works in winter mode (C.H + DHW heating) the three way valve directs
the heating medium to either central heating or feed cylinder circuit.
The priority is to heat the DHW Cylinder, at the same time the central heating circuit
is off. When the boiler heats the DHW Cylinder the boiler power is limited to 1/3 of its
nominal power. To change maximum boiler power (when the boiler heats the DHW
Cylinder) an advanced unit settings must be adjusted. If the WE-008 sensor for cylinder
water temperature control is applied (connected to the Tzas input on the ZIO board) you
can change the water temperature setting in cylinder by using button. The digital
display (J) will show the cylinder temp. setting. To set the temp. press or If the
thermostat for cylinder temperature control is applied (connected to the WZ input on
the ZIO board), the temperature setting on front panel is not available. You can set the
temp. directly on the cylinder thermostat. You can read the following working parameters
by pressing button.
A display shows (in sequence): inlet temp. (G,D,F indicators are on), outlet temp. (G,E,F
indicators are on), medium ow rate through the boiler (H indicator is on), estimated
power with which the boiler currently heats (I indicator is on). Pressing button again
allows you to set the the temperature of CH medium. Pressing button (when you
