Integration with Building Management Systems (BMS)

Over 95% of all M2G installations are to boilers and buildings where a Building Management Systems (BMS) is already in place. M2G works in harmony with your existing BMS, whether the BMS is providing time scheduling, boiler sequencing, weather compensation (variable temperature control) or demand control. There are no conflicts or duplication with these control strategies. Remember M2G is addressing the issue of dry cycling.

When the M2G is integrated with a BMS, the M2G is interlocked by fail safe relays that are connected in series to the burner/boiler control or stat circuit. The BMS is also connected into this circuit via volt free contacts.

The BMS system will give a ‘call for heat’ or an enable signal; the M2G will in turn check for boiler demand and the boiler memorised load profile (heating demand). The M2G’s patented adaptive algorithms will ensure that the best firing stage is established for the current load conditions. This will involve either enabling the boiler to fire to meet a genuine demand for heat from the building(s), or invoking a ‘save mode’ when the demand for heat is simply the result of standing heat losses from the boiler(s).

To further complement the operation of BMS with M2G, it is possible to interface the inputs/outputs of the M2G using M2GConnect, to volt free relays and in this way it would be possible for the BMS system to directly monitor the M2G operations if required.

Building management systems control various and well defined strategies for heating, cooling and lighting etc. In many cases the BMS will have a central control and a number of outstations connected to all the required elements of the building facilities. To understand what control strategies are in place with your BMS your FM provider, maintenance provider or BMS company will help.
