How to use these instructions
These instructions describe how the Danfoss district heating controller
ECL Apex 10 is set up.
Heating system example
In this user guide we describe the setup by means of an example comprising a
weather compensated heating circuit and a domestic hot-water (DHW) circuit.
Please note that the system diagrams in this instruction are principle drawings
and they do not contain all components that are necessary in your system.

ECL Apex 10
The heating supply is provided with a strainer and a differential pressure
switch / filter guard (DI1), as well as sensors to monitor primary temperature
(ST2) and pressure (SP1).
The heating circuit consists of a motorized control valve (M1), a heat exchanger
with flow (ST3) and return (ST4) temperature sensors, two sequentially
controlled pumps (P1 and P2) with flow (SP2) and return (SP3) pressure
transmitters. The heating circuit as such is weather compensated by means of
the outdoor temperature sensor (ST1).
The DHW comprises a motorized control valve (M2), a heat exchanger with flow
(ST5) and return (ST6) temperature sensors, one set of twin-pump controlled
pumps (P3 and P4) supervised by a differential pressure switch (DI2).

Mounting and wiring
Mounting of an analog output extension module
1. Disconnect the ECL Apex 10 from the mains supply.
2. Remove the processing unit from the base part by pressing in the plates on
both sides.
3. Mount the extension module in the base part.
4. Remount the processing unit on the base part.

ECL Apex 10
Mounting of an additional I/O module
1. Move the protective cap from the ECL Apex 10 to the I/O module.
Remove the protective cap
from the connection plug on
the right-hand side of the base
part.
Place the cap on the connection
plug of the I/O module, which is
to be mounted on the far right-
hand side of the array.
2. Assemble the I/O module and the ECL Apex 10.

Connect service tool
The service tool is connected to the
controller by placing the plug from
the PC or PDA into the service tool
socket on the controller.
The controller has to be switched
ON before the service tool program
is started.
The first time the service tool is connected to a new controller version, the
start-up of the service tool will take longer than usual.
Login with user name SUPV
To change the controller
configuration you have logon as
SUPV (supervisor) and enter the
belonging access code.
On delivery the controller is
supplied with the access code 123.

When you are logged on to
the controller, you will get this
overview. Normally it will be empty
until one or more circuits have
been configured. It will always be
possible to return to the overview
by pressing the button at the
bottom left.
If there is a red bell at the bottom
right, it tells you that there is an
active alarm.
