Alpha Intec 50CS
EXTERNAL SENSOR:
Flow temperature depending on the external temperature and user
adjustments of the central heating temperature
.
Condensate drain:
To drain the condensate produced by the
appliance, it is necessary to connect to the
drainage system by means of acidic condensate
resistant pipes having a diameter of at least 22
mm. The system connecting the appliance to the
drainage system must be carried out in such a way
as to prevent freezing of the liquid contained in
it. Before appliance commissioning, ensure that
the condensate can be correctly removed. Also,
comply with national and local regulations on
discharging waste waters.
For further detail see Section 1.11.
Electrical connection:
The boiler has an IPX5D protection rating for the
entire appliance. Electrical safety of the appliance
is reached only when it is correctly connected
to an efficient earthing system as specified by
current safety standards.
The power supply cable must be connected to a
230V ±10% / 50Hz mains supply respecting L-N
polarity and earth connection , this network
must also have a multi-pole circuit breaker.
1.4 REMOTE CONTROLS ANd
PROGRAMMABLE ROOM
THERMOSTATS (OPTIONAL)
The boiler is suitable for use with programmable
room timer thermostats or remote controls,
which are available as optional kits.
Alpha programmable room thermostats are
connected with 2 wires only. Carefully read the
user and assembly instructions supplied with
the kit.
Installation on low temperature system:
The boiler can directly supply a low temperature
system by acting on parameter 'P66' (Service
Engineers Document - Programming the PCB)
and setting the flow temperature adjustment
range 'P66/A' and 'P66/B'. In this situation it is
good practice to insert a safety device in series
with the power supply and boiler. This device is
made up from a thermostat with a temperature
limit of 60°C. The thermostat must be positioned
on the system flow pipe at a distance of at least 2
metres from the boiler.
T = Central heating temperature
TE = External temperature.
TMAX - TMIN = Selected flow temp. range.
The following controls for the InTec50CS are also available from Alpha:
Part No. 3.021395, CAR V2 ....................InTec50CS wired modulating thermostat
Part No. 3.021622, Crono 7 .....................InTec50CS wired digital thermostat
Part No. 3.021624, Crono 7RF ................InTec 50CS wireless digital termostat
1.5 EXTERNAL TEMPERATURE SENSOR
(OPTIONAL)
The boiler is suitable for use with the external
sensor (Fig. 1-3), which is available as an optional
kit. The sensor can be connected directly to
the boiler electrical system and allows the
maximum flow temperature to be automatically
decreased when the external temperature
increases, in order to adjust the heat supplied to
the system according to the change in external
temperature. The external sensor always operates
when connected, regardless of the presence or
type of room thermostat used and can work
in combination with Alpha programmable
thermostats. The correlation between system
flow temperature and external temperature is
determined by the parameters set in menu 'M5'
under 'P66' according to the curves represented
in the diagram (Fig. 1-4). The external sensor
must be connected to terminals 38 and 39 on
the boiler PCB, (Fig. 3-2).
