    It is only necessary to set the correct date and time in connection with the first use of the ECL Comfort 110 controller or after a power break of more than 36 hours (see the chapter on Adapting the ECL Comfort 110 controller).

  • Page 12: Room T Limit (Room Temperature Limitation) 3000

    This section is a general description for Room temperature limitation and is only relevant if you have installed a room temperature sensor (S2). The ECL Comfort 110 adjusts the desired flow temperature to compensate for the difference between the desired and the actual room temperature.

  • Page 13: Comfort T (Desired Room Temperature In Comfort Mode) 3180

    The “Intgr. time” function can correct the desired flow temperature with max. 8 degrees. OFF: The control function is not influenced by the ‘Intgr. time’. Minor value: The desired room temperature is adapted quickly. Major value: The desired room temperature is adapted slowly. VI.LV.A1.02 © Danfoss | 2016.05 | 13...
  • Page 14 The actual room temperature is 2 degrees too high. The ‘Gain - max.’ is set to -3.5. The ‘Gain - min.’ is set to 2.0. Result: The desired flow temperature is changed by 2 x (-3.5) = -7.0 degrees. 14 | © Danfoss | 2016.05 VI.LV.A1.02...

  • Page 15: Compensation 1 And 2 4000

    The example shows that the desired flow temperature can be influenced when the compensation temperature gets below “Compensation temperature value 1”. Also, the desired flow temperature can be influenced when the compensation temperature gets above “Compensation temperature value 2”. VI.LV.A1.02 © Danfoss | 2016.05 | 15...

    Setting the compensation temperature value 1. When the temperature, measured by S1, falls below or gets higher than the set compensation value, the ECL Comfort 110 changes the desired flow temperature. The influence is set in ‘Gain - max.’ and ‘Gain - min.’.

  • Page 17: Compensation 2 5000

    Setting the compensation temperature value 2. When the temperature, measured by S1, falls below or gets higher than the set compensation value, the ECL Comfort 110 changes the desired flow temperature. The influence is set in ‘Gain - max.’ and ‘Gain - min.’.

  • Page 18: Intgr. Time (Integration Time) 5065

    ‘Gain. min.’ (4063) is set to 2.5. The actual compensation temperature is 2°C (3 degrees below the limit value). Result: The desired flow temperature is changed by 2.5 x 3 = 7.5 degrees. 18 | © Danfoss | 2016.05 VI.LV.A1.02...

  • Page 19: Return T Limit (Return Temp. Limitation) 6000

    This section is a general description for Return temperature limitation and is only relevant if you have installed a return temperature sensor (S4). The ECL Comfort 110 adjusts the desired flow temperature to compensate for the difference between the limitation temperature and the actual return temperature.

  • Page 20: Limit (Return Temperature Limitation Value) 6030

    Minor value: The desired flow temperature is changed quickly. Major value: The desired flow temperature is changed slowly. If the ‘Gain’ is too high and / or the ‘Intgr. time’ too low, there is a risk of unstable control. 20 | © Danfoss | 2016.05 VI.LV.A1.02...
