The ECA 110 is a supplement to the ECL Comfort 110 versions without a timer program, e.g., the code nos. 087B1261 and
087B1251 (see page 1). With the ECA 110 it will be possible to set personal schedules in terms of start and stop times of
the system and thereby optimize the energy supply.
Domestic hot water (DHW)
(Application 116)
Application 116 example
Constant DHW temperature control with heat exchanger
Basic principles
Constant DHW temperature control with heat
exchanger or storage tank
Typically, the flow temperature is adjusted
according to the desired flow temperature.
• Adjustment of DHW temperature
If the measured DHW temperature is lower
than the desired temperature, the motorized
control valve is opened gradually and vice
versa.
• Return temperature limitation
The return temperature to the district heating
supply should not be too high. If so, the
desired flow temperature can be adjusted
(typically to a lower value) thus resulting in a
gradual closing of the motorized control valve.
In boiler-based heating supply the return
temperature should not be too low (same
adjustment procedure as above).
• Circulation pump control
The circulation pump is ON when the desired
DHW temperature is higher than a user-
defined value (factory setting: 20 °C).
