An Ecopilot system is a system affecting the indoor climate. Estimated savings are based on all central systems for heating, cooling and ventilation being included in Ecopilot. It is recommended to have 3 or more temperature sensors per zone. It is recommended to have approximately one sensor/100m². A reference room sensor can only be active/selected in one zone.


PowerPilot is designed to level and limit the power for water-based heating systems during the day.
The primary target is not to reduce the total energy usage, but to level the power outtake by borrowing and returning energy from a slow system like a water-based radiator system. Normally this strategy has a very small impact on the the indoor climate, but depending on how the peak power limit is set, it can have.

For a cooling system the peak power will probably occure in the afternoon just before ventilation units are turned off in a normal office building.

If PowerPilot this is used for cooling systems, it would probably only act as a limiter as the chilled water usually is distributed via ventilation.


  • Configured Ecopilot.
  • Main heat energy meter with:
  • power reading in [kW].
  • update time < 5min.
  • One or more water based radiator heating systems with flow temperature control [°C].

Target group:

  • Building heated by district heating.
  • Building with larger temporary loads during the day.
    (Like Multi residential buildings were the domestic hot water is a momentary significant load).
  • Customer who benefits from reducing the power peaks.


Heatmaps is an addon to the dynamical floor plans and require Ecopilot. The feature uses the Ecopilot zone settings for temperature and CO2 level to color the surrounding area of each sensor. Surrounding area will fade between blue, none and red depending on the actual value being close or outside the low or high limit.
Relative feature will not be colored as humidity sensors can't be selected in Ecopilot.

Heatmaps function require that point names are described on the following form:

  • b[building number]fl[floor number]z[zone number].room[medium][room number].cm
  • b[building number]fl[floor number]z[zone number].roomtempcont[room number].ms
  • b[building number]fl[floor number]z[zone number].roomtempcont[room number].cs

Building and zone number may be excluded if not applicable.

Supported [medium] types:

  • temp for temperature.
  • carbon for CO2-level.
  • hum for relative humidity.

Supported units:

  • [°C] for temperature.
  • [ppm] for CO2-level.
  • [%rH] or [%] for relative humidity.

WDC Room Controllers

This feature is an ability to automatically create room controllers using the settings from the corresponding Ecopilot zone. Outputs for heating, cooling and air volume are automatically paired with a room sensor selected in Ecopilot by their point names. The controller is energy efficiant and harmonises well with the indoor climate.

  • Sensor and output are pared by point name depending on building, zone, floor and room number.
  • Temperature and CO2 level sensors are supported.
  • The controller will use the settings in the cooresponding Ecopilot zone.
  • A temperature setpoint offset is generated for personal adjustment of +/- 1°C.
  • One temperature sensor can only be paired with one heating output signal.
  • One temperature sensor can only be paired with one cooling output signal.
  • An average room temperature of multiple sensors can be automatically generated.
  • Cooling and air volume will follow each other based on temperature demand.
  • For damper outputs a minimum and maximum damper position is automatically generated for adjustment.
  • Easy to maintain as it has no control loop settings.
  • Wireless sensors can be used.

Room sensors

The function supports temperature and CO2 level sensors named as below.

Point name Description
.roomtempcont[room number].ms Room temperature
.roomtempcont[room number].cs Room CO2 level

Multiple room sensors can be automatically averaged to control the same outputs. First sensor is named .ms1 second .ms2 and so on. A new average sensor .ms will be generated and used for the control loop.

sensor 1 = fl01.roomtempcont101.ms1
sensor 2 = fl01.roomtempcont101.ms2
sensor 3 = fl01.roomtempcont101.ms3

A new sensor for the average room temperature will be automatically generated as

Possible output types

Output Description
.out Standard analog 0-100% output.
.out Standard analog 0-100% output.
.pwm Pulse width modulated digital output.
Cycle time is 15min and shortest activation time is 1min.
This gives 1/15 = 6,7% as smallest output

Cooling signals

Point name Description
.aircooler[room number]. Cooling sequence active when ventilation is active. Chilled beams, cooling coils, Fan Coils
.cooler[room number]. Cooling sequence active when cooling systems are
.fancooler[room number]. Stand alone fan cooler

Heating signals

Point name Description
.airheater[room number]. Heating sequence active when ventilation is active. Heating coils, Fan Coils
.heater[room number]. Heating sequence active heating systems are
.fanheater[room number]. Stand alone fan heater
.radheater[room number]. Radiator valve
.floorheater[room number]. Under floor heating

Air quality signals

Point name Description
.vavdamper[room number]. Supply/Extract air damper.
This signal assumes an air flow control in the device
.supdamper[room number]. position-controlled supply air damper.
Min and max damper position will be generated for adjustment
.exhdamper[room number]. position-controlled extract air damper.
Min and max damper position will be generated for adjustment

Cold air down draught protection

The generated controllers has a built-in cold air draught protection for the following outputs.

  • heater
  • fanheater
  • radheater
  • floorheater

The function kicks in when the heating demand for the cooresponding Ecopilot zone is above 15% and the room temperature is below the zones comfort temperature with hysteresis. When the protection is active the output is controlled partly depending on heating demnad and partly on room temperature. The controller reverts back to normal control, room temperature, when the heating demand decrease below 10% or the room temperature decrease above the zones comfort temperature with hysteres.
