SUMMER is not selected (symbol --). You
must set a temperature value (this tempe-
rature will have no effect on the equithermal
control mode).
2. Select the “equithermal mode – curve
slope” and set the E6 symbol – see page
6.
3. Select the “equithermal mode – parallel
shift” and set the symbol (P-).
4. By pressing the MODE button, save the
setting in the memory and return back to
the starting position.
After a few days (when the premises have
been heated up), readjust the curve slope
as required:
5. If the indoor temperature does not
signifi cantly changes with outdoor tempe-
rature changes, the curve selection was
correct. The temperature can be changed
to a higher or a lower value by changing
the size of the parallel shift – see the part
“Controls and signals – Equithermal mode
– Parallel shift”.
Important:
If the indoor temperature
changes signifi cantly with outdoor tem-
perature changes, with the indoor tempe-
rature increasing with a dropping outdoor
temperature, select a lower value curve
and vice versa.
Using the boiler with equithermal
control and room control unit
A room control unit extends the equivalent
control mode by time control and a heating
economy mode (e.g. at night).
Setup procedure:
• set the equivalent control as described
above.
• connect the room control unit to the boiler
(after removing the wiring terminal jumper)
and set the required temperature during
the comfortable temperature period on the
control unit to about 5˚C higher than the
temperature reached by the equithermal
control. For economy mode period (at night,
when absent), set on the room control unit
the actual required temperature – it must
be always at least 3˚C lower than the actual
comfortable temperature.
Example:
• the (comfortable) indoor temperature
maintained by the equithermal control is
21˚C.
• set the room control unit for the comfor-
table temperature period to 26˚C and for
the economy mode period to the actual
required temperature, e.g. 16˚C.
Setting the boiler output
The boiler is factory-set to its maximum
output.
Important: Output setting may be changed
only by an authorised technician.
Hot water heating in COMFORT
mode
In this mode the boiler automatically main-
tains the primary circuit preheated. Using
this function will result in getting the hot
water supply even faster.
Two control methods are available:
1. Permanent function – the setting is
described in section “Controls and signals”.
The hot water heat exchanger is continu-
ously preheated to approximately the set
hot water temperature value.
Important:
The permanent hot water pre-
heating function is enabled only when the
system is set to the SUMMER mode (with
heating turned off), or during intervals when
the boiler is turned off by the room control
unit and the equithermal control mode is
switched off.
2.
Single-action function – this function is
activated in the basic mode when the boiler
is not heating by opening a hot water tap for
a short while (time between opening and
closing the hot water tap 2 – 5 seconds).
