Function definition
The module allows an alternative heat source with water routing to be
connected to a EMS 2 control system.
Cylinder charging/discharging:
the availability of and demand for heat
in the cylinder is measured via two cylinder temperature sensors. By
controlling valves and pumps accordingly, the module ensures that heat
energy demand is met by charging and discharging the cylinder. If
required, the module also controls a mixer with temperature sensor in
the system flow.
Return temperature increase:
the module controls the pump and valve
via the flow temperature and, if applicable, the return/flue gas
temperature at the alternative heat source in order to maintain a
minimum return temperature at the alternative heat source.
Control of active alternative heat source:
the module can switch
electrically activatable alternative heat sources (e.g. pellet stove with
boiler function) on/off directly depending on the heat energy demand, or
modulate these if possible.
Blocking/releasing:
if there is sufficient heat in the buffer cylinder, the
conventional heat source is blocked and bypassed via a bypass valve.
If the alternative heat source cannot supply enough heat to the buffer
cylinder, the conventional heat source is released. When using a heat
source with electronics EMS 2 electronics (e.g. MX 25 from V1.44), the
interlock can be applied for the DHW and heating separately.
Heating circuit pump for heating circuit 1 (Heating circuit installed):
in a system with a stand-alone alternative heat source (ME 200 address
9 or 10), the module ME 200 can switch the pump of the first heating
circuit on or off. The heating circuit pump is either connected to ME 200
(At the boiler) or MM 100 with address 1 (At the module).
Integration on a cascade system with MC 400(from 3 heat sources):
in a cascade system with MC 400, the alternative heat source must be
placed at the last position of the cascade.
