Reserve boiler
Deactivating control over additional boiler is
done after setting zero value of switching off
for this parameter.
Controlling extension of the boiler
is coshared with alarm extension.
Deactivating
additional
boiler
control will cause that this
extension will be controlled by
module of controlling alarms.
When main boiler is fired-up, and its
temperature exceedes preset value i.e. 25ºC,
then controller switches off additional boiler
(it will give constant voltage 6 VDC for
terminals 30-31). 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
voltage to terminals 30-31 which should
activate the additional boiler.
Switching the controller into “
Boiler
Off
” mode causes deactivating the
additional boiler.

Connection of alarm signaling
The controller can report alarms by
activating external devices like ring or GSM
device to short messages SMS sending.
Alarm signaling device must be connected
through a relay. On the matter that output is
shared with reserve boiler control output, in
order to activate the output for alarm
function, you must first disable the reserve
boiler control. To do this you should in the
menu:
Service settings
→
Boiler settings
→
Reserve boiler
set zero value of its deactivating temperature
and then set the H output (mod B) to
Alarm
in the menu:
Service settings
→
Output H (mod B)
The alarm signaling should be connected via
relay to terminals 30-31 additional B module.
