49 EXTERNAL CONTROLS VIA SWITCHED LIVE, 0-10V INPUT OR OPENTHERM
Note that the boiler requires a 4 minute pump overrun
period.
The boiler warranty will be invalid if this is not provided.
It is recommended that the pump overrun functionality is
achieved by connecting the pump to the boiler CH Pump
connections (see diagram), although this functionality can
be replicated with external controls (for example a Building
Management System).

If the CH Pump connection is used and the electrical current
draw is 1.3A inductive or less then the pump can be connected
directly into the CH Pump connection (a Grundfos 40/50 UPS is
OK).
If the current draw is more than this (eg a Grundfos 40/120
UPS) then an external relay should be operated by the CH
Pump connection, with the external relay then powering the
pump.
