Pump Connection
Milborne boiler regulation system includes the simultaneous management of up to three circulators.
Therefore, if a low temperature circuit supplied by its own circulator is present and a general pump is to be
installed on the system, it will be necessary to choose which one of the two devices should be managed by the
Boiler Master Control.
This operation is carried out by setting the relevant parameter during commissioning.
The pumps shall be installed using an adequate contactor, as shown in Figure B.1.2
Figure B.1.2
BMS Connections
For 0 - 10v connection, the input signal must be connected to terminals 13 & 14 - see figure B.1.3
Note:
any safety interlocks MUST be wired across the 0– 10v circuit using suitable low voltage contact ratings.
For connection of an external alarm device, use terminals 18 & 19, which are volt free and rated at 230v - see
figure B.1.3
For an optional programmable room thermostat, use terminals 9 & 10 for the high temperature heating room
sensor and terminals 11 & 12 for the low temperature heating room sensor - see figure B.1.3
