Connection possibilities for the standard PCB (CB-01)
Standard PCB CB-01 can be found in the connection box. Various
thermostats and regulators can be connected to the standard PCB.
Connecting the system pump
1. Connect a system pump to the Pump terminals of the connector.
Important
The maximum power consumption is 300 VA.
The function of the system pump can be changed using parameters
PP015, PP016 and PP018.
For more information, see
Parameters - FSB-WHB-HE-150-300, page 50
Changing the parameters, page 49
Connecting a PWM system pump
A PWM system pump can be connected to the boiler and can be
controlled in a modulating way from the boiler
1. Connect the PWM pump to the PWM terminals of the connector.
Important
Contact us for more information.
Connecting an outdoor sensor
An outdoor sensor can be connected to the Tout terminals of the
connector. In the case of an on/off thermostat, the boiler will control the
temperature with the set point from the internal heating curve.
1. Connect the two-wire cable to the Tout terminals of the connector.
Important
OpenTherm regulators can also use this outdoor sensor. In such
cases, the desired heating curve must be set on the regulator.
