HVAC APPLICATIONS
The room heaters, available in the different forms of radiators, decorative radiators and
towel warmers, represent the most common heat exchange terminals in residential
buildings. The heaters are used in hydronic systems for room heating only, which uses
small terminals for the convection heat exchange (with prevailing natural effect), thanks
to a relevant temperature difference between the heat transfer fluid and the room air.
The system shown in the example is intended for a residential building and provides for
the distribution of the heat transfer fluid to zones by means of two distribution manifolds.
Control with Ekinex
The room air temperature is controlled by room thermostats EK-E72-TP (D), installed
in the pilot rooms of the two zones, in combination with the actuator EK-HE1-TP (C)
which controls the ON / OFF servomotors of the zone valves (3).
The EK-TM1-TP time / astronomical digital switch (A) ensures that the system operate
according to predefined time scheduling and is constantly synchronised with date and
time by the (optional) GPS module EK-GPS-1 (B).
The optional supervision by means of the Delégo Server (E) allows you to monitor and
control the home automation system by means of an App for mobile devices (9) and/
or a Delégo touch-panel (F).
Mounting position for room thermostats
For optimum adjustment, Ekinex® room thermostats should preferably be installed on
an interior wall at a height of 1.5 m and at least 0.3 m from the doors. Thermostats
may not be installed near heat sources such as radiators or appliances or in locations
subject to direct sunlight. If necessary, a weighted average between the temperature
value measured by the sensor integrated in the room thermostat and the value received
via bus from another device (e.g. from an Ekinex® pushbutton or multisensor) can be
used for adjustment.
