Definitions
Air duct temperature
Temperature measured in the air duct where the temperature is
to be controlled.
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.
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.
Controller mode indicator
Black arrow to the right of the symbols indicating the present
mode.
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.
Factory settings
Settings stored on the ECL Card to simplify the set up of your
controller the first time.
Flow temperature
Temperature measured in the flow at any time.
Flow temperature reference
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.
Heating circuit
The circuit for heating the room / building.
Heat curve
A curve showing the relationship between actual outdoor
temperature and required flow temperature.
DHW circuit
The circuit for heating the domestic hot water (DHW).
