7.5 Definitions

The definitions apply to the ECL Comfort 210 / 296 / 310 series.
Consequently, you might come across expressions that are not
mentioned in your guide.
Accumulated temperature value
A filtered (dampened) value, typically for room and outdoor
temperatures. Is calculated in the ECL controller and is used
to express the heat stored in the walls of the house. The
accumulated value does not change so rapidly as the actual
temperature.
Air duct temperature
Temperature measured in the air duct where the temperature
is to be controlled.
Alarm function
Based on the alarm settings, the controller can activate an output.
Anti-bacteria function
For a defined period, the DHW temperature is increased in order
to neutralize dangerous bacteria, e.g. Legionella.
Balance temperature
This setpoint is the basis for the flow / air duct temperature. The
balance temperature can be adjusted by the room temperature,
the compensation temperature and the return temperature. The
balance temperature is only active if a room temperature sensor
is connected.
BMS
Building Management System. A supervisory system for remote
control and monitoring.
Comfort operation
Normal temperature in the system controlled by the schedule.
During heating the flow temperature in the system is higher to
maintain the desired room temperature. During cooling the flow
temperature in the system is lower to maintain the desired room
temperature.
Comfort temperature
Temperature maintained in the circuits during comfort periods.
Normally during daytime.
Compensation temperature
A measured temperature influencing the flow temperature
reference / balance temperature.
Desired flow temperature
Temperature calculated by the controller on basis of the outdoor
temperature and influences from the room and / or return
temperatures. This temperature is used as a reference for the
control.
Desired room temperature
Temperature which is set as the desired room temperature. The
temperature can only be controlled by the ECL Comfort controller
if a room temperature sensor is installed.
If a sensor is not installed, the set desired room temperature
however still influences the flow temperature.
In both cases the room temperature in each room is typically
controlled by radiator thermostats / valves.
Desired temperature
Temperature based on a setting or a controller calculation.
Dew point temperature
Temperature at which the humidity in the air condensates.
