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.
Analogue input
This input has two modes: control based on temperature or based on heat
output. If this input is used, the OT communication from the boiler is
ignored.
1. Connect the input signal to terminals 0–10 of the connector.
Change the mode of the analogue input using the parameter EP014.
0-10 Volt analogue temperature regulation (°C)
The appliance can be controlled by a 0-10 Volt input signal. When
configured to temperature-based, the 0–10 V signal controls the boiler
supply temperature.
