Terminology
Heating water temperature
The heating water temperature is the radiator
flow temperature. The higher the heating water
temperature, the higher the heat transfer to
radiators.
Boiler
Gas fired boiler, which can be combined with a
DHW cylinder.
Combination boiler
Gas fired boiler with an instantaneous water
heater and DHW QuickStart.
DHW loading
Heating up the DHW cylinder.
DHW QuickStart
The heating water in the boiler will be held at
a certain temperature during summer mode,
to be able to supply hot water as rapidly as
possible from the instantaneous water heater
of the combination boiler. The day program
switches this function ON and OFF during
summer mode.
Heating program
Subject to program selection, the day program
switches the gas fired boiler from heating to
economy mode or from heating mode to
heating OFF and vice versa.
Domestic hot water program
In a combination boiler, the day program
controls the DHW QuickStart, and for a boiler
with a DHW cylinder, it switches the cylinder
loading ON and OFF.
4
Winter mode
Central heating and DHW according to the
day program.
Summer mode
Central heating OFF, DHW according to the
day program.
Heating mode/economy mode
In winter mode, two room temperatures can
be selected. One for central heating mode and
one for economy mode, when the room
temperature will be setback to economy
temperature.
The day program changes over between
heating and economy mode.
Standards and regulations
In gas fired combination boilers, the analog
room thermostat ART complies with the
following Directives:
- Low Voltage Directive: 73/23/EEC
- EMC Directive: 89/336/EEC
