n Flue gas damper control (FgV)
Not applicable.
n Hydraulic valve control (HdV)
In a cascade configuration, a hydraulic valve prevents heat loss when
the boiler is not running. Connect the hydraulic valve to the HdV
terminals of the terminal strip. The running time of the hydraulic valve
must be programmed with parameter p30.
n Control of external gas valve (EgV)
If there is a heat demand, an alternating voltage of 230 VAC, 1 A
(maximum) becomes available on the EgV terminals of the connector
to control an external gas valve.
