OPERATION
BioClass iC 66
is set by default as an “Only Heating” boiler. Optionally, to increase the system's
performance, a Domestic Hot Water tank (
Sanit
) offered by
DOMUSA TEKNIK
may be connected.
5.1
“Only heating” operation
In this operation mode, it is needed to set a temperature of the boiler (see “Boiler temperature set
point selection”), of the room thermostat (
TA
1
) or of the
LAGO FB OT+
remote control (if there is any
connected) in order to start the boiler up. The burner will start running to heat the water of the boiler.
When the temperature of the boiler overtakes 60 ºC, the heating pump is switched on to heat the water
of the installation. The burner modulates the heat output level to maintain the set point temperature
selected and the pump continues running until the installation reaches to the temperature selected in
the room thermostat or remote control (if there is any connected). When the temperature in the boiler
overtakes 4 ºC the boiler set point temperature the burner stops until the temperature decreases 10
ºC behind the set point temperature, in this moment the burner is switched on again.
It is possible to disable the heating service (
Summer
mode
) by setting to "
OFF
" the boiler temperature
set point. In this operating mode only the DHW service is available if there is a DHW tank installed.
5.2
Operating with a Sanit DHW tank (Option)
BioClass iC 66
boiler could be installed together with a DHW tank
Sanit
, within the product range
offered by
DOMUSA TEKNIK
, to obtain Domestic Hot Water service. Follow the instructions described
in section “Installing a Sanit hot water tank” to assure a correct installation.
In this operating mode, it is needed to set a DHW temperature set point (see “DHW temperature set
point selection”) in order to start DHW service up. The burner will start running and the DHW pump or
valve will switch on if the boiler's temperature overtakes 60 ºC and it is higher than the one into DHW
tank. When DHW tank temperature reaches the set point temperature, after a poscirculation period of
time (parameter
P.16
of “Technical Menu”), the boiler will be able to heat the heating installation by
switching on the heating pump. The burner modulates the heat output level to maintain the boiler
temperature set point. The heating pump will stop when the room temperature reaches the set point
set at the room thermostat or remote control (if there is any connected).
It is possible to disable the DHW by setting to "
OFF
" the DHW temperature set point.
NOTE: To assure the optimal DHW service, the heating service will not be available while
the DHW service is activated to heat the DHW tank.
