Substation for indirect heating for single-family, semi-detatched
and terraced houses as well as flats. With two heating circuits and
instantaneous domestic water heater. Designed for wall-mounting
with connections in top and bottom of substation.
The temperature for the heating circuits is controlled by a Danfoss ECL
310 controller in combination with electronic actuators. The supply
temperature is calculated by the controller on basis of the outdoor
temperature.
The domestic hot water temperature is also controlled by the ECL
310 in combination with an electronic actuator.
Please note:
Your substation may look different than the substation shown, as vari-
ants with other components may be supplied.
Instructions for the fitted components will always be supplied to-
gether with the substation.
Heating circuit
The temperature for the heating circuit is controlled electronically by
the Danfoss ECL controller. The supply temperature ist calculated by
the controller on basis of the outdoor temperature.
The ECL Comfort 310 controller is loaded with a selected application
by means of an ECL Application Key (Plug-&-Play). The Application
Key contains information about application, languages and factory
settings.
The controller is factory preset to turn off the heating automatically
in the summer period.
The controller settings can be changed in accordance with the en-
closed producer instructions for the mounted controller.
