The 0–10 V signal controls the boiler flow temperature in a linear way. This
control modulates on the basis of flow temperature. The output varies
between the minimum and maximum value on the basis of the flow
temperature set point calculated by the controller.
Connect the telephone connector as follows:
1 + 2 0–10 V / status input
3 + 4 status output
Connecting room thermostats per zone
The SCB-10 is fitted with three R-Bus connectors. They can be used to
connect room thermostats per zone. The R-bus connectors are related to
the other zone-specific connectors on the SCB-10.The R-Bus connector
supports the following types:
R-Bus thermostat (for example, the Smart TC°)
OpenTherm thermostat
OpenTherm Smart Power thermostat
On/off thermostat
The software recognizes which type of thermostat is connected.
Connecting system sensors
Connecting system sensors (NTC 10k Ohm/25°C) for circuits (zones).
Connecting the domestic hot water (DHW) sensor
Connecting the domestic hot water (DHW) sensor (NTC 10k Ohm/25°C).
Connecting contact temperature sensors
Connecting contact temperature sensors (NTC 10k Ohm/25°C) for system
flow, DHW temperatures or zones (groups).
Connecting the calorifier tank anode
Connecting a TAS anode (Titan Active System) for a calorifier tank.
