Sketch your application
The ECL Comfort controller series is designed for a wide
range of heating and hot-water systems with different
configurations and capacities.
If your system differs from the diagrams shown in section
10, you may want to make a sketch of the system about to
be installed. This makes it easier to use the Installer’s Guide,
which will guide you step-by-step from installation to final
adjustments before the end-user takes over.
The controller is pre-programmed with factory settings that are
shown in the relevant sections of this guide.
However, you might come across some settings that are not listed
in this instruction. These settings could be related either to recent
updates or the use of optional modules (which are described in
the instructions in question).
How to use this guide
This guide is divided into two parts:
• User’s Guide: Yellow sections 1-7
• Installer's Guide: Grey sections 10 and onwards
The application P30 is very flexible. These are the basic principles:
Typically, the flow temperature is always adjusted according to
your requirements.
The flow temperature sensor (S3) is the most important sensor.
The desired flow temperature at S3 is calculated in the ECL
Comfort controller, based on the outdoor temperature (S1). The
lower the outdoor temperature, the higher the desired flow
temperature.
The motorized control valve (M1) is opened gradually when the
flow temperature is lower than the desired flow temperature and
vice versa.
The return temperature (S4) to the district heating supply should
not be too high. If so, the desired flow temperature can be
adjusted (typically to a lower value) thus resulting in a gradual
closing of the motorized control valve. In boiler-based heating
supply the return temperature should not be too low (same
adjustment procedure as above).
If the measured room temperature does not equal the desired
room temperature, the desired flow temperature can be adjusted.
The circulation pump, P1, is ON when the desired flow
temperature is higher than 20 °C or the outdoor temperature is
lower than 2 °C.
Before you start

Installation
The ECL Comfort controller is a universal controller that can
be used for various systems. Based on the shown standard
systems, it is possible to configure additional systems.
In this section you find the most frequently used systems. If
your system is not quite as shown below, find the diagram
which has the best resemblance with your system and make
your own combinations.

System diagrams in this instruction are principal drawings and do
not contain all components which are necessary in your systems.

Installation
For easy access, you should mount the ECL Comfort
controller near the system. Select one of the three
following methods:
• Mounting on a wall
• Mounting on a DIN rail
• Mounting in a panel
Screws and rawlplugs are not supplied.
Mounting on a wall
Socket for mounting on wall: Order code No. 087B1149.
Mount the terminal box on a wall with a smooth surface.
Establish the electrical connections and position the
controller in the box. Secure the controller with the fixing
screw.
Mounting on a DIN rail
Mounting kit: Order code No. 087B1145.
A mounting kit is necessary to mount the box with the
controller on a DIN rail.
Mounting in a panel
Connector set: Order code No. 087B1148.
The panel plate thickness must not exceed 3 mm.
Prepare a cut-out with the dimensions 93 x 139 mm. Pull off
the right side of the lid by means of a screwdriver.
Insert the controller into the panel cut-out and fix it with the
two locks which are placed diagonally in two corners of the
controller.

14a

Installation
It is important that the sensors are mounted in the correct
position in your system.
The temperature sensor mentioned below are sensors used
for the ECL Comfort 200 and 300 series which not all will be
needed for your application!
Outdoor temperature sensor (ESMT)
The outdoor sensor should be mounted on that side of the
building where it is less likely to be exposed to direct
sunshine. It should not be placed close to doors, windows or
air outlets.
Flow temperature sensor (ESMU, ESM-11 or ESMC)
Place the sensor max. 15 cm from the mixing point. In
systems with heat exchanger, Danfoss recommends that the
ESMU-type to be inserted into the exchanger flow outlet.
Make sure that the surface of the pipe is clean and even
where the sensor is mounted.
Return temperature sensor (ESMU, ESM-11 or ESMC)
The return sensor should always be placed in / on a pipe with
return water flow.
Room temperature sensor (ESM-10, ECA 60 / 62 room
panel or ECA 61 / 63 remote control)
Place the room sensor in the room where the temperature is
to be controlled. Do not place it on outside walls or close to
radiators, windows or doors.
DHW temperature sensor (ESMU or ESMB-12)
Place the DHW temperature sensor according to the
manufacturer’s specification.
Boiler temperature sensor (ESMU, ESM-11 or ESMC)
Place the sensor according to the boiler manufacturer’s
specification.
Flow / air duct temperature sensor (ESM-11, ESMB-12,
ESMC or ESMU types)
Place the sensor so that it measures a representative
temperature.
Surface temperature sensor (ESMB-12)
Place the sensor in the surface of the floor.
Valid for ESM-11: Do not move the sensor after it has been
fastened in order to avoid damage to the sensor element.

Installation

Connecting the room panel / remote control
The ECA 60 / 61 / 62 / 63 is activated by the setting in line 10
(section 32).
The ECA 60 / 61 / 62 / 63 is powered by the system device bus
which means that the bus must be active. The bus is activated by
setting the controller address to 15 (section 32, line 199).
Override
For an active override, you have to choose the mode
“scheduled operation”! Input S1 ... S4 can be used for override
purposes (section 32, line 141).
Connection example without ECA 9010
If the override switch has goldplated contacts, you can
choose one of the following solutions or a combination of
both:
Closed switch: Closed switch:
Comfort temperature Setback temperature
Open switch: Open switch:
Scheduled operation Scheduled operation
Connection example with ECA 9010
The ECA 9010 module is powered by the system device
BUS, which means that the BUS must be active. The BUS is
activated by setting the controller address to 15 (line 199). To
avoid influence from contact resistance, the use of ECA 9010
is recommended.
