It is recommended to avoid fully opened thermostats on some radiators and fully shut-off on others. Higher temperature at the top and lower temperature at the bottom part of radiators means that the system operation is correct. - Page 25 Danfoss ECL Comfort 210 or 310 The temperature for the heating circuits can be controlled electroni- cally by a Danfoss ECL 210 or 310 controller. The ECL controller is supplied with an ECL Application Key , which contains information about application, language and factory settings, adapted to the type of system, for which it is ordered.

For start-up follow the above start-up instructions. It is recommend- able to vent the system after the summer period again. Substation with Danfoss ECL: The circulation pump for heating is automatically switched off in periods without heat demand. To prevent the pump from block- ing in periods without heat demand, the controller automatically switcheson the pump for some minutes every third day. -

If rinsing with clean water is not sufficient, the exchanger can also be cleaned by circulating a cleaning agent approved by Danfoss (e.g. Kaloxi or Radiner Fl cleaning fluid) through the exchanger. Both these cleaning fluids are environmentally friendly and can be disposed off through the standard sewer system. -
