Definitions
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 heating / DHW circuit during comfort periods.
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.
DHW circuit
The circuit for heating the domestic hot water (DHW).
Factory settings
Settings stored in the controller to simplify the setup of your controller the first time.
Flow / DHW temperature
Temperature measured in the flow at any time.
Heating circuit
The circuit for heating the room / building.
Heat curve
A curve showing the relationship between actual outdoor temperature and required
flow temperature.
Humidity, relative
This value (stated in %) refers to the indoor moisture content compared to the max.
moisture content. The relative humidity is measured by the ECA 62 / 63.

Limitation temperature
Temperature that influences the desired flow / balance temperature.
Pt 1000 sensor
All sensors used with the ECL Comfort controller are based on the Pt 1000 type. The
resistance is 1000 ohm at 0 °C and it changes with approx. 3.9 ohm / degree.
Optimization
The controller optimizes the start / stop time of the scheduled temperature periods.
Based on the outdoor temperature, the controller automatically calculates when to start
/ stop in order to reach the comfort temperature at the set time. The lower the outdoor
temperature, the earlier the start time. During optimization the comfort / setback
symbol will blink.
Return temperature
The temperature measured in the return can influence the desired flow temperature.
Room temperature sensor
Temperature sensor placed in the room (reference room, typically the living room)
where the temperature is to be controlled.
Room temperature
Temperature measured by the room temperature sensor, room panel or remote
control. The room temperature can only be controlled directly if a room temperature is
measured. The room temperature can influence the desired flow temperature.
Schedule
Schedule for periods with comfort and setback temperatures. The schedule can be made
individually for each week day and it consists of 2 comfort periods per day.
Setback temperature
Temperature maintained in the heating / DHW circuit during setback temperature
periods.
Time bar
The time bars illustrate scheduled periods with comfort temperature.
Weather compensation
Flow temperature control based on the outdoor temperature. The control is related to a
user-defined heat curve.
The definitions apply to the Comfort 110 series. Consequently, you might come across
expressions that are not mentioned in your guide.
