Example: connection of reserve boiler to regulator: 1-
regulator, 2 – reserve boiler (gas- or oil-fired), 3 – RM
84-2012-35-1012 relay and GZT80 RELPOL base plate.
Standard version of the regulator is not
equipped with a relay.
Reserve boiler control is switched off upon
setting the Output H1 (Output H2) function
to the Reserve boiler.

and then set the Temperature of reserve
boiler activation to a value different from
zero. Switching off the reserve boiler control
is performed after setting the zero value of
this parameter.
Once the boiler has been fired up, and its
temperature has exceeded the preset value
(e.g. 25ºC), regulator switches off the
reserve boiler and applies voltage 12VDC at
output H, which causes release of coil of
relay and opening its contacts. Once the
boiler temperature has dropped below the
value set in the parameter of Temperature of
reserve boiler activation, the regulator stops
to supply voltage to the output H, and the
reserve boiler switches on.
Entry of regulator to “Stand-by”
mode causes the reserve boiler
switches on.
It is recommended to change-over regulator
to “Stand-by” mode once the pellet boiler
has failed and there is a need to use reserve
boiler. In “Stand-by” mode, control of CH
system is disabled (mixer, HUW and boiler
pumps and mixer control are inactive).

valve in reserve boiler. 1 – regulator, 2 – reserve
boiler, 3 – relay, 5 – switching valve servo (with
limit switches). Note: terminals 22,21,24 have to
be galvanically insulated from terminals 12,11,14.
12.15 Connection of alarm signalling
Regulator may announce alarm conditions by
activating an external device (e.g. a bell or
GSM device to send a text message).
Connect alarm annunciator as shown in
below fig. through the relay. Due to the fact
that this output H is shared with the control
output of the reserve boiler, in order to
activate the alarm functions on this output, it
is necessary to first switch off the reserve
boiler control. To do this, please in the
menu:
