Assembly of transmitter should
be done by a person with proper
qualifications, according to valid
norms and regulations.
To activate control over additional boiler set
the
parameter Additional boiler
deactivation temperature on value
different than zero.

Additional boiler
Deactivating control over additional boiler is
done after setting zero value of switching off
for this parameter.
Controlling extension of the boiler
is co-shared with alarm extension.
Deactivating additional boiler
control will cause that this
extension will be controlled by
module of controlling alarms.
In case when terminals 39-40 are connected
with additional boiler and additional boiler
control is deactivated (by selecting zero
value of its switching off temperature) then it
is required that
Code of signalling active
alarms is set for value 0)
(Menu

Service settings
→

settings
→
Alarm).
It is to protect against situation when
reporting alarms compatible with alarm
signal codes causes activation of additional
boiler.
When pellet boiler is fired-up, and its
temperature exceeds preset value i.e. 25
degrees C, then controller switches off
additional boiler (it will give constant power
AC 6V for terminals 39-40). It will power the
coil of transmitter and disconnecting its
joints. After decreasing boiler temperature
below parameter temperature of additional
boiler switching off the controller stops giving
power to joints 39-40 which should activate
the additional boiler.
Switching the controller into
STAND-BY mode causes
deactivating the additional boiler.
