Example of connecting an external alarm device: 1 -
regulator, 2 - external alarm device, 3 - relay RM 84-
2012-35-1012.
5.8 Connecting the damper actuator
The air damper actuators are connected in
accordance with the electric diagram. The
regulator cooperates only with single-phase
air damper actuators of the open / close type
(ON-OFF).
5.9 Connecting the STB temperature
limiter
If the furnace temperature exceeds 95 ° C,
the power supply to the fuel feeder and the
burner fan is cut off by the safety
temperature limiter. Restarting requires
resetting the limiter. To do this, unscrew the
nut (1) covering the reset button (2) and
press the button.
Resetting the STB temperature limiter: 1 - cover nut, 2 -
reset button.
The button can be pressed only after the
furnance temperature drops below 95 ° C.
The fan and fuel feeder power will be
restored.
If the regulator is not factory-equipped with
a safety temperature limiter, it should be
connected to the regulator terminals 1-2 as
an external device.
The safety temperature limiter
must have a rated operating
voltage of at least ~ 230 V and
should
have the applicable
approvals.
Dangerous voltage is present on
terminals 1-2.
If the STB is not installed on terminals 1-2 of
the regulator, a bridge must be used, which
should be made with an insulated wire with a
cross-section of at least 0.75 mm2, with
insulation thick enough to meet the safety
requirements for the boiler.
The regulations require the use of
the STB limiter.
5.10 Connecting the room panel
The maximum length of the wires connecting
the room panel (room thermostats) with the
regulator should not exceed 30 m. This
length can be longer, when wires with a
cross-section greater than the recommended
0.5 mm2 are used.

• Four-wire connection
Connect according to the electric diagram.
• Two-wire connection
Two-wire connection requires a 5… 12 VDC
power supply with a minimum current of 200
mA. Power supply points: GND and VCC
connect to an external power supply, which
is not a standard regulator equipment.
Connect the D + and D- lines as shown in
the
electric diagram.
