Path - First page - Products - Optimising Compensator - DTE 611

APPLICATION

Designed for control of small and medium-size heating plant rooms comprising:

• 1 single- or two-stage boiler, or double furnace (two single-stage burners).

• 1 centralised heating plant room.

• 1 calorifier for DHW.

• Telemanagement enabled via   : to allow communications to a local or remote PC via a modem .

• Communications with other controllers via serial connection to share sensor information.

Essential detectors:

• 1 outside sensor.

• 1 heating flow sensor.

• 1 boiler sensor.

Optional accessories:

• 1 room sensor.

• 1 DHW sensor.

• 1 or 2 flue gas sensors.

• 1 remote override.

FEATURES

• Power supply: 230V~.

• Consumption: 5VA.

• DIN 105 x 115 modular enclosure.

• Protection: IP 40.

• Digital programming by means of 4 keys and alphanumeric display.

• Setting dates for heating season and automatic switching between GMT – BST.

• Seven 24hour programs, two 7day programs, 25 holiday periods and one special period with dates.

• Fixed point or variable control of boiler according to max. temperature requested by heating, etc zones:

  • On-Off control of one single- or two-stage burner or 2 single-stage burners.

  • Control boiler anticondensing (closure of heating valve).

  • Theoretical metering of operating hours of the two burner stages.

• Compensated control of centralised heating plant room:

  • Modulating control of valve by 3-wire reversible actuator.

  • Control of heating pump in relation to times and demand for heat.

  • Optimisation of start and stop times.

  • Minimum and maximum limits of flow temperature.

  • Manual correction heating curve point of origin (compensation for intermediate seasons).

  • Automatic adjustment of heating curve in relation to room temperature (ambient authority).

  • Eco Off function: switching off heating zones when weather mild.

  • Remote override for changing program in use (as alternative to temperature flue gases & On-Off alarm).

• Control production of DHW:

  • On-Off control of calorifier pump by timed programs independent of heating.

  • "DHW priority" (closure heating valve).

  • Antibacteria function: once a week at 70 °C for 90 minutes.

• Summer exercise function for valves and pumps.

• Three inputs On-Off alarms.

• One configurable input: remote control or flue gases temperature Pt 1kΩ and On-Off alarm.

• One configurable input: measurement 4 ... 20mA or flue gases temperature Pt 1 kΩ and On-Off alarm.

• Alarms for plant malfunctioning and for open or short sensor circuit.

• Degree-days metering.
