3.2.2. OpenTherm control
You must connect the OpenTherm
control to the green connector block
ports (1) - (2)
The setpoint is calculated by the actual ambient
temperature and the temperature set. The OpenTherm
control sends the setpoint value to the boiler.
OpenTherm control with outdoor sensor.
The value of the outdoor sensor (connected to the green
connector block ports 3-4) is sent to the PCB. The PCB
passes on the outdoor sensor value to the OpenTherm
control, which calculates the setpoint with the value of
the outdoor sensor and sends the setpoint to the boiler.
3.2.3. 0÷10V control
Ports (1) - (2) of the green connector
block must be open.
You must connect
the 0÷10V control to
of the connector
block, mounted on
the electronics
casing ports 6 and 7
In the menu structure you can set the configuration either
on temperature or on heating power (parameter u).
The 0÷10V control sends the setpoint value to the boiler.
3.2.4. Outdoor sensor
When using the outdoor sensor the option of OpenTherm
control expires.
When using the outdoor sensor the option of 0÷10V
control expires.
Connect the outdoor sensor (NTC of
12kOhm @ 25°C) to the green
connector block ports (3) - (4)
Take in account by placing the sensor that sunshine can
influence the reading temperature of the outdoor sensor
significantly.
The setpoint is calculated by the actual outdoor
temperature and in the menu structure adjustable
parameters. The outdoor sensor sends the setpoint value
to the boiler.
Parameter C: Maximal flow temperature (default
82°C).
Parameter O/b: Minimal flow temperature (default
40°C).
Parameter O/S: Slope, the change of flow temperature
depending on the outside temperature (default 20 = 2:1).
Parameter O/d: This parameter sets specific point; the
flow temperature at outdoor temperature of 20°C (default
40°C).
Parameter O/t: Summer/winter switch blocks the
burner on ports (1) – (2) of the green connector block
when the outdoor temperature is above the O/t-value
(default 40°C).
The burner is off. After the after run time also the pump is
off.
