12.11 Connection of boiler's room
thermostat
Note: the boiler room thermostat
should be switched off if the whole
central heating system of the
building is supplied through a mixing
valve equipped with electric servo.
The regulator may work with mechanical or
electronic room thermostat, which opens the
contacts once the preset temperature has
been achieved.
Set-up the operation of room thermostat in:
Boiler settings
 Room thermostat 
Thermostat selection  Universal
Once the preset room temperature
has been reached, thermostat opens
its contacts and the display shows:
.
Once the temperature in the room, in which
the room thermostat is installed, has reached
the preset value, regulator reduces the
preset boiler temperature by the value set in
Inc. p. b. temp. thermostat and the display
shows . This will cause longer breaks in
boiler operation (the boiler will remain in
SUPERVISION mode) and the same,
temperature in heated rooms will drop.
Moreover, the boiler pump (CH pump) may
be interlocked for a certain time by opening
the contacts of the room thermostat in
heated rooms. To activate this function -
enter:
Boiler settings
→
Room thermostat
→
CH pump standstill
and set the value of this parameter >0.
Setting the value of e.g. ,,5” causes the
pump will be stopped by the room
thermostat for 5 min. When ,,0” is set, the
CH pump will not be stopped by the room
thermostat. Once this time has elapsed, the
regulator switches on CH pump for a time set
in CH pump op t. th. on e.g. 30s. This
feature prevents from excessive cooling of
the system caused by a pump stop.
The pump interlock by opening
the
contacts of the room
thermostat may be activated only
upon making sure the boiler will
not be overheated.
12.12 Connection of reserve boiler
The regulator can control a reserve boiler
(gas- or oil-), eliminating the necessity of
enabling or disabling this boiler manually.
The reserve boiler will be enabled if the
temperature of the pellet boiler drops, and
disabled when the pellet boiler reaches an
appropriate temperature. Connection to a
reserve boiler, e.g. oil-boiler one, should only
be made by a qualified fitter, in accordance
with the technical documentation of this
boiler.
The reserve boiler should be connected via
relay to terminals 43-44 (Output H).
Model diagram of layout for connecting a reserve
boiler to the regulator, where: 1- regulator, 2 –
reserve boiler (gas- or oil-), 3 – module U3,
consisting of relay RM 84-2012-35-1012 and base
GZT80 RELPOL.
In a standard version, the regulator is not
equipped with the U3 module.
It should to perform assembly and
installation of the module by
yourself, in conformity with the
applicable standards.
Set the temperatures of reserve boiler switch
on/off:
Service settings
 Boiler settings 
Reserve boiler  Reserve boiler 
Reserve boiler activation temp.
Control of reserve boiler is off upon setting
this parameter at ,,0”.
Then should set the support for output H for
reserve boiler:
Service settings
 Output H = Reserve
boiler
Once the boiler has been fired up, and its
temperature has exceeded the preset value
(e.g. 25
 C), regulator switches off the
reserve boiler and applies voltage 12V DC at
output H, which causes release of coil of U3
module relay and opening its contacts. Once
the boiler temperature has dropped below
