• Activate the warmstart system by briefly turning the
knob (1) all the way clockwise (position a). The green
LED (2) lights up. Then select the required tempera-
ture, e.g. setting b, see 4.5.1.
The water is kept at a constant temperature of 55 °C
and is available immediately as you turn on a tap.
• Switch off the warmstart system by briefly turning the
knob (1) all the way anti-clockwise (position c). The
green LED (2) goes out. Then select the required hot
water outlet temperature again, e.g. setting b.
4.5.3 Drawing hot water (ecoTEC combination
boilers only)
On opening a hot water tap (1) at a supply point (basin,
shower, bath, etc) the ecoTEC combination boiler will
automatically operate to deliver hot water.
On closing the tap the boiler switches OFF (or continues
to operate for central heating if required).

Fig. 4.13 Setting the maximum radiator temperature control
Set the maximum radiator temperature control to the
desired setting using the control knob (1).
We recommend the following settings:
– Left setting during spring and autumn,
– Middle setting during mild winter,
– Right setting during cold winter.
When you adjust the temperature, the set value is
shown in the display (2). After five seconds the display
returns to standard mode (the current heating flow tem-
perature). Normally you can adjust the knob (1) continu-
ously up to a flow temperature of 75 °C. However, high-
er temperatures can be set on your appliance, have
your engineer make adjustments so that you can oper-
ate the heating system at higher flow temperatures.
