The CB-01 connection PCB
The CB-01 is placed in the control box. It provides easy access to all the
standard connectors.
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.
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 temperature sensor
An outdoor temperature sensor can be connected to the Tout connector.
1. Connect the two-wire cable to the Tout connector.
Use below mentioned sensors, or sensors with identical characteristics.
Set parameter AP056 to the installed outdoor temperature sensor type.
AF60 = NTC 470 Ω/25°C
QAC34 = NTC 1000 Ω/25°C
When an on/off thermostat is also connected, the boiler will control the
temperature with the set point from the internal heating curve. OpenTherm
controllers can also use the outdoor temperature sensor. In that case, the
desired heating curve must be set on the controller.
Frost protection combined with outdoor sensor
The central heating system can also be protected against frost in
combination with an outdoor sensor. The radiator valve in the frost-
sensitive room must be open.
1. Connect the outdoor sensor to the terminals Tout of the connector.
The frost protection works as follows with an outdoor sensor:
At outside temperatures below -10 °C: the circulation pump switches on.
At outside temperatures above -10 °C: the circulation pump continues to
run and then switches off.
