General information
PLEASE NOTE! Some models may have a slightly different appearance,
but the control function is in principle the same as described below.
Commissioning
Commission the unit in accordance with instructions on page 6 -7.
Filling the system
Filling of water to the heating system must be done according to the
instructions on page 6 (item 5 - GETTING STARTED).
Check and tighten all connections before adding water to the system,
as vibrations during transport may have caused leaks. After having
added water to the system, tighten all the connections before per-
forming leak test.
Then heat up the system, check the connections and tighten once
again if necessary.
Before adding water to the system and first start-up, check if:
- pipes are connected according to the circuit diagram,
- heat meter is mounted,
- shut-off valves are closed,
- threaded and flanged connections are tightened.
Differential pressure controller (common return pipe
- only Application A266)
The differential pressure controller, Danfoss AVP-F reduces the high
fluctuations in pressure in the district heating network, ensuring a
small and constant operating pressure across the unit. This ensures
optimum operating conditions for the control equipment.
The differential pressure controller closes on rising differential
pressure. The differential pressure controller is preset to a fixed value
from factory and should not be adjusted afterwards.
Please refer to enclosed producer instructions for further information.
Instructions AVP-F
Danfoss ECL Comfort 310
The substation is supplied with an Danfoss ECL 310 controller. The ECL
controller is supplied with an ECL Application Key A266. The application
Key contains information about application, language and factory set-
tings, adapted to the type of system, for which it is ordered.
Note! Various applications can be loaded.
The controller is factory-set for local language and the running time for
the actuator (heating circuit) is preset for the actual application.
General controller settings such as “Time and Date” must be entered
during commissioning of the controller. And also the desired supply
flow temperature must be set.
Please refer to enclosed manufacturer instructions for the ECL 210/310
controller to set the required temperature for the heating circuit :
ECL Application Key Box with ECL Comfort 210/310 user guide and
mounting guide, for further information.
We recommend that your order commissioning of the controller with your
local Danfoss representative.
Note, in systems that feature only floor heating it is important that the
supply temperature does not exceed 35°C, and ALWAYS check the in-
structions from the floor supplier ( typically for wooden floors).
Ac valve, unit with control of heating- and DHW circuits,
Application A266
For controlling the heating circuit the S 22, A266 is supplied with a
Danfoss AMV 10 actuator with Danfoss valve type VM2, placed on the
primary return flow pipe. The AMV actuator is electrically wired to the
controller from factory.
Please refer to enclosed producer instructions for further information.
Instructions AMV10
Factory setting
The actuator has undergone a functional test and is preset from factory.
In the event of operating disturbances the actuator can be shut off man-
ually in accordance with enclosed instructions, by turning the manual
override knob on top of the actuator clockwise. Please note that the
knob can be “tight” to turn.
