n Control of external central heating pump (Pump)
An external central heating pump can be connected to the Pump
terminals of the connector. The maximum input power is 400 VA.
n Control of external three-way valve (3wV)
The external three-way valve (230 VAC) can be used when
connecting an indirectly heated calorifier. The neutral position of the
three-way valve can be set using parameter p34.
The three-way valve is connected as follows:
4 N = neutral
4 C = central heating
4 D = tank
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.
n Operation signal and failure signal (Status)
The alarm or operation signal is selected using parameter p40.
4 If the boiler is operating, the operation signal can be switched via
a potential-free contact (maximum 230 VAC, 1 A) on the No and
C terminals of the connector.
4 If the boiler locks out, the alarm can be transmitted via a potential-
free contact (maximum 230 VAC, 1 A) on the Nc and C terminals
of the connector.
n Pressure switch minimum (Gps)
The minimum gas pressure switch shuts the boiler down if the inlet
gas pressure becomes too low. Connect the minimum gas pressure
switch to the Gps terminals of the connector. The presence of the gas
pressure switch must be set using parameter p41.
n Heat Recovery Unit (Hru)
Connect the wires from the heat recovery unit to the Hru terminals of
the connector. The presence of the heat recovery unit must be set
using parameter p4".
