 "summary": "The MV311 is a thermal energy converter that pairs with a flow sensor and two temperature probes to measure heating and cooling energy. On BACnet MS/TP it gives the energy and volume totals both as integer counters (Positive Integer Values) and as real numbers (Analog Values), live power, flow and temperatures as Analog Inputs, alarm states as Multistate Values and error bit strings.",

 "notes": [
  "Counters exist twice: PIV 0-11 (integer) and AV 0-11 (real) with matching names ending _C and _V.",
  "Units follow the converter's unit settings; all energy counters share one unit and all volume counters another. Object descriptions change with the selected units.",
  "The four error objects are BitString Value objects (listed as type Other). Bit texts for RTD_ERROR and SUPP_ERROR are not clearly printed.",
  "P_TYPE_SEL is writable only if the local settings allow it; RST_SEL_CNT is write-only (write Active to reset, reads Inactive).",
  "Aux input counters (instance 10-11) can be volume, gas volume or electrical energy depending on the aux input setup."
