The shown diagram is a fundamental and simpliﬁed example and

does not contain all components that are necessary in a system.

If the system you are about to install diﬀers from the shown

diagram of a standard heating system, feel free to sketch an outline

for comparison. Adaptation of systems, see section 10.

Sketch your application

The ECL Comfort controller series is designed for a wide

range of heating, hot-water and cooling 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 C14 is very ﬂexible. These are the basic principles:

The most important temperature sensor in the system is S3, which

measures the ﬂow / air duct temperature. A constant comfort or

setback temperature is kept at S3 according to schedule.

Additional temperature sensors have the following

functions:

S1: Compensation temperature sensor:

Can correct the S3 reference temperature. The compensation

temperature could be the outdoor temperature.

S2: Room temperature sensor (typically):

When used, the temperature at S3 is considered as

the balance temperature. This means that the comfort or

setback temperature now is related to S2 instead of S3.

S4: Limitation temperature sensor:

Can correct the S3 reference temperature. The limitation

temperature could be the return temperature.

Fan and pump are controlled according to the schedule.

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.

The functions can only be realized with ECL Comfort 300 and as

of controller version 1.04.

10.1 Unit heater system with constant room

temperature control

Control principle:

PI control of the ﬂow temperature (S3) and P control of the

room temperature (S2). The adjusted ﬂow temperature is

controlled by the motorized valve M1. The P1 fans are

controlled by relay R1, and the circulation pump P2 by

relay R2.
