Placing The Temperature Sensors - Danfoss ECL Comfort 210 Installation Manual

Installation Guide

2.4 Placing the temperature sensors

2.4.1 Placing the temperature sensors
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 210 and 310 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 temperature sensor should always be placed so that it
measures a representative return temperature.
Room temperature sensor
(ESM-10, ECA 30 / 31 Remote Control Unit)
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.
Boiler temperature sensor (ESMU, ESM-11 or ESMC)
Place the sensor according to the boiler manufacturer's
specification.
Air duct temperature sensor (ESMB-12 or ESMU types)
Place the sensor so that it measures a representative temperature.
DHW temperature sensor (ESMU or ESMB-12)
Place the DHW temperature sensor according to the manufacturer's
specification.
Slab temperature sensor (ESMB-12)
Place the sensor in a protection tube in the slab.

ESM-11: Do not move the sensor after it has been fastened in order to
avoid damage to the sensor element.
ESM-11, ESMC and ESMB-12: Use heat conducting paste for quick
measurement of the temperature.
ESMU and ESMB-12: Using a sensor pocket to protect the sensor will,
however, result in a slower temperature measurement.
