Positioning probe T1
for antifreeze control
When using the electric coil, BEP or a pre-heating
hydronic coil, it is necessary to move the PT 1000
sensor on the fresh air intake to upstream of the
preheating element.
The PT 1000 sensor is provided in the preheating
accessory. You must drill a hole in the external
air intake duct and then insert the sensitive
element in the channel and then seal the hole.
The probe cable must be taken to the
electrical equipment and connected to Terminal
T1 in the place of the standard probe mounted
inside the unit. Then disconnect connector T1
of the internal probe and connect the connector
T1 of the external probe. When DIP 1 is ON,
the connector to replace is the T3.
Notes
on mounting the electric coil
The inlet of the heater must be
fitted with a fixed mesh or device that prevents
touching the air intake of the element.
The distance between the heater and an elbow,
a valve, a filter etc. must be at least
twice the diameter of the duct, otherwise the
flow of air through the heater might be irregular
and cause activation of the thermal overheat
protection.
The heater must be insulated as per the regulations
relating to ventilation ducts. The insulation material
must always be flame retardant. The cover of the
heater must be free of insulation, so that the
identification
tag
can
be
cle
-
arly seen and the cover can
be removed.
The installation area of the heater must remain
accessible to permit replacement and servicing.
The minimum distance between the metal casing
of the heater and any wood or other combustible
material must be 30 mm.
MAINTENANCE
The unit is maintenance-free and requires only
a periodic field test.
The electrical panel can be facing upwards or
sideways, at an angle of 90° max.
The panel must
NOT
face downwards.
OVERHEATING
When the thermal overheat protection with manual
reset is activated, you must take the following
measures: do not tamper with the heater in any
way, e.g. do not remove the cover. Refer to an
authorised electrician. Disconnect from the
mains power supply and identify the cause for
activation of the overload device. The overload
device can be reset once the fault has been
resolved.
