class=\"wp-block-heading\" id=\"connections\">Connections<\/h2>\n\n\n\n<p><strong>NOTE &#8211;&nbsp;<span style=\"color: #ff0000;\">The mains supply to the ESCTBE\/B MUST be from the same source as the heating systems programmer, this will ensure that there is only one point of electrical isolation for safe working.<\/span><\/strong><\/p>\n\n\n\n<p>I used 1mm 4 core and earth from the ESCTDE\/B to the heating connection box, the ESCTDE\/B does not have an earth connection, so this wire was parked, the unit requires a permanent 230v feed, the temperature calling relay changeover contacts are <strong>NOT<\/strong> volt free, although they are simply wired in series with the existing cylinder thermostat.<\/p>\n\n\n\n<p>If the <b>Legionella&nbsp;<\/b>setting is active on the ESCTDE\/B, the unit will automatically switch 230v to the Domestic Hot Water motorised valve (NOTE- this overrides any programmer settings), which in turn will bring on the heating, the output from the ESCTDE\/B will remain on for 1 hour when the tank temperature is above 61\u2103.<\/p>\n\n\n\n<p>As the bending radius of the connecting wires within the unit is quite tight, I used ferrules on the end of the wires, this ensures that no &#8216;whiskers&#8217; can cause problems later.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><a
