Analogue input
A choice can be made with this control between control based on temper­
ature or heat output. If this input is used for 0-10 V control, the OT commu­
nication 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

2 Parameter
3 Maximum flow temperature
4 Calculated value
The 0–10 V signal controls the boiler supply temperature. 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.

Analogue output-based control
The 0 - 10 V signal controls the boiler output. This control modulates on
the basis of the heat output. The minimum output is linked to the boiler's
modulation depth. The output varies between the minimum and maximum
value on the basis of the value defined by the controller.

Blocking input
The boiler has a blocking input. This input relates to the BL terminals of
the connector.
Change the function of the input using parameter
Warning
Only suitable for potential-free contacts.
Important
First remove the bridge if this input is used.
