Page: 21 / 149

VI.13 Direct duct expansion coil (this function must be specified at the time of ordering)
A maximum 24 V 2A output is provided to control the start/stop of your cold unit, to be connected between terminals DO7
and 2 (provide a relay on the condensation unit).
You should also shift the supply air probe after the direct expansion coil.
VI.14 Electric coil associated with VORT NRG EC FIRST (specified at the time of ordering)
It is possible to add an electric coil to the VORT NRG EC FIRST unit. In this case we provide you with a heating signal 0-
10V (terminal 21-22) as well as the terminals 18-19 to bring your safety thermostat’s NF contact (break contact by
temperature rise). If the VORT NRG EC unit is linked to an electric coil provided with a CAB-CBE (electric coil housing),
follow the diagram as given below.
VI.15 VORT NRG EC PREMIUM BE and VORT NRG EC INFINITE BE electric heating coil
On the PREMIUM BE and INFINITE BE versions, the electric coil is already installed in the unit. The safety thermostat and
the 0-10V control are connected.
