11. Installation instructions – specially for S substations
Controller ECL 210
Supply voltage:
230 V AC – 50 Hz
Power consumption: 5 VA
Actuator AMV 150
Supply voltage:
230 V AC – 50 Hz
Power consumption: 8 VA
Pump (Wilo Yonos Para / Alpha2)
Supply voltage:
230 V AC – 50/60 Hz
Power consumption: Max. 40 Watt / max. 25 Watt
Electrical connection (only for S substations)
The electrical connection of the unit must be performed by authorised
personnel.
The unit is to be connected to a 230 V AC mains power supply.
The power supply/connection must be carried out in accordance
with the applicable regulations and instructions.
The substation must be connected to an external switch so that it
can be disconnected in connection with maintenance, cleaning and
repairs or in the event of an emergency.
S substations are available with Danfoss ECL 210 as extra equipment.
Installation of outdoor sensor (only for S substations ordered
with Danfoss ECL)
The outdoor temperature sensor is delivered separately with the
substation.
It is to be mounted on site as shown in the drawings to the right.
Always mount the sensor on the coldest side of the building (normally
the north side).
It must not be exposed to morning sunlight, and must not be po-
sitioned above windows, doors, ventilation ducts, balconies under
overhanging roof sections, or close to any other heat source.
Installation height: approx. 2.5 m above ground level.
Temperature range: -50 to 50° C
Electrical connection
The cables can be connected to the sensor in any order.
Connection cable: 2 x 0.4 - 1.5 mm²
Connect the cable ends in terminals 29 and 30 in the ECL 210
controller.
(For ECL 110 - terminals 1 and 2).
Connections for radiator circuit
S substations are fitted with connections for direct connection of a
radiator circuit before the mixing loop.
The connections are typically used to connect one or more radiators
that are not to be regulated by the mixing loop.
The connections are positioned as shown in the photo to the right.
The connections are sealed with blind plates, which you must remove
if you wish to use the connections.
Connections with a red arrow are for radiator supply, while connec-
tions with a blue arrow are for radiator return.
Connections for radiator circuit – (cut-out in insulation cover)
On fully insulated system types, it is necessary to cut a section out
of the insulation cover (for the connection pipes to the connection
pieces) as shown in the photo to the right.
