Sketch your applicationThe 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 guideThis guide is divided into two parts:• User’s Guide: Yellow sections 1-7• Installer's Guide: Grey sections 10 and onwardsThe 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 1.04.10.1Unit heater system with constant room temperature controlControl 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.System settingsCircuitLineDescriptionRecomm.settingICBalance temperature60 °CI2Temperature at S3 limit min/max30 °C / 90 °CI85Application selection0I89Relay output status R20System diagrams in this instruction are principal drawings and do not contain all components which are necessary in your systems.Identifying the system type10a

The temperature is held at a constant level by the motorized valve M1 in the primary circuit of the air heater. Fan P1 is controlled by relay R1, damper P2 by relay R2. System settingsThe desired temperature at S3 is set in display A (with the yellow side of the card facing you). The setting of the balance temperature (grey side, line C) has no function in this application.CircuitLineDescriptionRecomm.settingI85Application selection0I87R2 relay cut-in delay180 sec.
