Installation Guide ECL Comfort 210 / 310, application A275 / A375 7.2 Application Ch.-o. valve / P (changeover valve / pump) 13051 Circuit Setting range Factory setting 3 OFF / ON ON Choose whether the DHW heating control is based on a changeover valve or a pump. OFF: Changeover valve ON: Pump Tank, sec. / prim. 13053 Circuit Setting range Factory setting 3 OFF / ON OFF Choose whether the heating of the DHW tank is dependent on the flow temperature at S3. OFF: The DHW tank is heated by means of the S3 temperature. ON: The DHW tank is heated separately. The S3 temperature has no influence on the DHW heating. DHW P post-run 13041 Circuit Setting range Factory setting 3 0 ... 30 m 0 m Set the DHW pump (P3) post-run time (minutes). The DHW pump can continue to be switched ON after the DHW heating procedure in order to utilize the remaining heat in the heat exchanger / boiler. 0 ... 30: Set the number of minutes for the post-run. Send desired T 13500 Circuit Setting range Factory setting 3 OFF / ON ON When the controller acts as a slave controller in a master / slave system, information about the desired flow temperature can be sent to the master controller via the ECL 485 bus. OFF: Information about the desired flow temperature is not sent to the master controller. ON: Information about the desired flow temperature is sent to the master controller. Frost pr. T (frost protection temperature) 13093 Circuit Setting range Factory setting 3 5 ... 40 °C 10 °C Set the desired flow temperature to protect the DHW system against frost. 5 ... 40: Desired frost protection temperature. When the changeover valve is chosen, pump P1 is ON at heating as well as at DHW heating demand. When the pump is chosen, pump P1 is ON at heating and OFF at DHW heating demand. In the master controller, 'Demand offset' must be set to a value in order to react on a desired flow temperature from a slave controller. 150 DEN-SMT/DK VI.GU.L1.02 Danfoss District Energy
Installation Guide ECL Comfort 210 / 310, application A275 / A375 Ext. input (external override), ECL 210 13141 Circuit Setting range Factory setting 3 OFF / S1 ... S8 OFF Choose the input for 'Ext. input' (external override). By means of a switch the controller can be overridden to Comfort or Saving mode. OFF: No inputs have been selected for external override. S1 ... S8: Input selected for external override. If S1...S6 is chosen as override input, the override switch must have gold-plated contacts. If S7 or S8 is chosen as override input, the override switch can be a standard contact. See the drawing for a connection example of an override switch to input S8. Ext. input (external override) — ECL 310 13141 Circuit Setting range Factory setting 3 OFF / S1 ... S10 OFF Choose the input for 'Ext. input' (external override). By means of a switch the controller can be overridden to ‘Comfort’ or ‘Saving’ mode. OFF: No inputs have been selected for external override. S1 ... S10: Input selected for external override. If S1... S6 is chosen as override input, the override switch must have gold-plated contacts. If S7 ... S10 is chosen as override input, the override switch can be a standard contact. See the drawing for a connection example of an override switch to input S9. The two drawings (override to comfort mode and override to saving mode) show the functionality. Choose only an unused input for override. If an already used input is applied for override, the functionality of this input is also neglected. See also ‘Ext. mode’. Choose only an unused input for override. If an already used input is applied for override, the functionality of this input is also neglected. See also ‘Ext. mode’.
