For wall-mounting and with variable connection possibilities. The HE supply temperature is controlled either by a self-acting ther- mostat T°C 200 or by a Danfoss ECL controller in combination with an electronic actuator. The ECL controller acts as the brain of the heating system.
Electronic control The temperature for the heating circuit can be controlled electroni- cally by either a Danfoss ECL 210 or a Danfoss ECL 310 controller (Fig. 3). The supply temperature ist calculated by the controller on basis of the outdoor temperature.
The substation is made of materials that cannot be disposed of together with household waste. Close all energy sources and disconnect all connection pipes. Disconnect and dismantle the product for disposal in accordance with the applicable local regulations for the disposal of the individual components. 16 DKDHR VI.GP.P2.02 Danfoss District Energy...

In rooms with radiators, the temperature is regulated using the radiator thermostats. Alternatively, the heating circuits can be regulated using fully auto- matic Danfoss ECL weather compensation equipment, - a Danfoss VX Solo II H2 (ECL 210/A260) VX Solo II HWP (ECL 210/A237)) ECL controller in combination with electronic actuator(s).
Always lead the blow-off pipes from the safety valves to a drain in accordance with applicable legislation. Expansion vessel The VX Solo II substations are equipped with an expansion vessel, which is factory set to 0,5 bar. 19 19 Danfoss District Energy VI.GP.P2.02 DKDHR...

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.

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.

ALPHA2 L, Installation and operating instructions Summer operation Substations with Danfoss T°C Thermostat In the summer, you can stop the pump by switching it off at the mains. However, remember to start the pump (briefly) at least once a month during the summer.
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.
The temperature in the DHW cylinder can be controlled by the Danfoss ECL controller in combination with an actuator + valve. Danfoss ECL Comfort 210/310 The application Key contains information about application, language and factory settings, adapted to the type of system, for which it is ordered.

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.
