Boiler start/stop control output.
See section 5.13.
The contacts are used for unit start/stop and
heat/cool control. They are only taken into
account if the unit is under remote operation
control (rEM).
These dry contacts are used for demand
limit selection. See description of these
contacts in section 3.6.2.
The remote demand limit selection contact
is active whatever the operating type of the
unit.
These dry contacts are used for setpoint
selection.
They are only taken into account if the unit
is in remote control operating type (rEM).
See the description of these contacts in
sections 3.6.4.
This contact is mounted in series with the
water flow control contact. It can be used for
any customer safety loop that requires that
the unit is stopped, if it is open.
If it is unused this contact must be bridged.
A RS-485 bus is used for connection to the
CCN.
