Power Supply - ECOFOREST ecoSMART e-source Manual Deusuario, Instalador Y Servicio Técnico

The relay terminal block provides digital outputs to control external equipment, such as circulator pumps, fans or open/closed
valves. Each relay should be powered externally with the operating voltage of the component to be controlled. Power is supplied to
each relay separately, so different operating voltages can be used in each. The following figure shows an example of an installation
of a relay power supply.
Each relay allows independent pole switching; it can thus control the switching on/off of the units, including those powered with a
different voltage. The capacity of the relays is 8A/250Vac per pole. If the equipment to be controlled exceeds this capacity, an
external relay or contactor must be installed. Shown below are examples of connections between circulator pumps and 3-way
valves with controls at 2 or 3 points.

Pay special attention to the maximum consumption allowed by each relay. Use an intermediate relay
or a contactor for the connection, if necessary.

4.2. Power supply

The e-source manager only requires one electrical connection. The power supply to the 24Vac transformer connects to it to power
the controller and other devices with low power consumption. The following table shows the characteristics of the necessary
