START CONDENS 25 - 29 Kis
Adjusting the heating water temperature with an external
probe connected
When an external probe is installed, the delivery temperature is au-
tomatically selected by the system, which quickly adjusts the ambi-
ent temperature according to variations in the outside temperature.
If you want to alter the temperature value (increasing or reducing
the value automatically calculated by the electronic card), use the
heating water temperature selector: turn it clockwise to increase the
temperature, or anticlockwise to reduce it.
The correction possibility is between -5 and +5 levels of comfort,
shown on the digital display by rotating the knob.
6.2 - Summer
The standard domestic hot water-only mode is activated by turning
the selector to the summer symbol
in response to a request for domestic hot water. The digital display
indicates the temperature of the domestic hot water.
6.3 - Pre-heating (faster hot water)
Turning the domestic hot water adjustment knob to the symbol
activates the pre-heating function. Bring the domestic hot water tem-
perature adjustment knob back to the required position. This func-
tion keeps the water in the domestic hot water exchanger hot, to re-
duce standby times when a request is made. When the pre-heating
function is enabled, the display shows the symbol
The display indicates the outlet temperature of the heating water or
the domestic hot water based upon the request in progress. During
burner ignition, following a pre-heating request, the monitor shows
the flashing symbol. To deactivate the pre-heating function, rotate
the domestic hot water temperature adjustment knob back to the
symbol . The symbol switches off. Bring the domestic hot water
temperature adjustment knob back to the required position.
This function cannot be activated when the boiler is OFF: function
selector to off (OFF).
6.4 - Adjustment of the domestic hot water temperature
To adjust the domestic hot water temperature (for baths, showers,
kitchen etc.), turn the dial with the symbol clockwise to increase the
value, or anticlockwise to decrease the value (mi. value 37°C - max.
value 60 °C). The boiler is in standby until the burner switches on
following a heat request. The boiler continues to function until the
temperatures set on the boiler are reached, or the heat request ter-
minates; it will then go back to standby. In the case of a temporary
stop the digital display shows the fault code.
. The boiler lights automatically
.
6.5 - Heating Temperature Control function (H.T.C.)
Turn the heating water temperature selector into sector highlighted
with white markers to activate the H.T.C. self-adjusting system: de-
pending on the temperature set on the ambient thermostat and the
time taken to reach it, the boiler automatically varies the heating
water temperature by reducing operating time, thereby achieving in-
creased comfort and energy savings.
6.6 - Reset function
To restore normal operation, turn the function selector to off, wait 5-6
seconds, and then turn it to the required position. At this point, the
boiler will restart automatically.
NOTE - If the attempts to reset the appliance do not activate opera-
tion, contact the Technical Assistance Centre.
6.7 - Temporary switch-off
In the event of temporary absences(weekends, short trips, etc.) set
the mode selector to (OFF).
9 In this way (leaving the electricity and fuel supplies enabled), the
boiler is protected by the following systems:
• Antifreeze: when the temperature of the water in the boiler drops
below 5°C the circulator starts and, if necessary, the burner at
minimum output to being the water temperature to safety values
(35°C). During the antifreeze cycle, the symbol
digital display.
• Circulator antiblocking: an operation cycle is activated every 24 h.
6.8 - Switching off for lengthy periods
If the START CONDENS Kis boiler is not used for a long time, the
following operations must be carried out:
• Set the mode selector to off (OFF)
• Set the system's main switch to "off"
• Close the fuel and water taps of the heating and domestic hot
water system.
9 In this case, the anti-freeze and circulator anti-locking systems
are deactivated.
• Drain the heating and domestic water system if there is any risk
of freezing.
