Iv.15. Electric Heater Battery - Vortice VORT NRG 600 EC Manuel D'utilisation Et De Mise En Marche

ENGLISH
Terminal 15 to +24 V (G) of the valve servomotor
Terminal 16 to 0 V (G0) of the valve servomotor
Terminal 17 to brown wire of the plate (hot signal)
Terminal 30 to black wire of the plate (cold signal)
Connect the NF contact (C and 2) of the THA (antifreeze thermostat ) to 5 and 6.
Possibility to connect the circulator to terminals DO3 of the controller and 18 of the terminal block (higher temperature
required) and to terminals DO4 of the controller and 19 of the terminal block (lower temperature required). (Caution:
the 24 V output is to be connected via a relay)
WARNING: in this case use one relay for each output and wire them in parallel to the M/A of the circulator
IV.14. Direct expansion coil for cooling only or reversible coil
For systems equipped with DX coil, the supplementary module is equipped with a condensate collector. Provision
must be made for collection of condensate via a siphon.
We provide :
• a 24 V output for system heating or cooling requirements
• a 0-10 V hot output and a 0-10 V cold output.
Heating requirement :
• 24 V output : Connect to terminals DO3 of the controller and 18 of the terminal block; allows a startup signal to be
sent to control a DX module (Caution: max. 12 V 2 A to be connected via relay)
• 0-10 V output : Connect to terminals 15 and 16 (15 = 0 V and 16 = 0/10 V)
Cooling requirement :
• 24 V output : Connect to terminals DO4 of the controller and 19 of the terminal block; allows a startup signal to be
sent to control a DX module (Caution: max. 12 V 2 A to be connected via relay)
• 0-10 V output : Connect to terminals 29 and 30 (29 = 0 V and 30 = 0/10 V)
WARNING : If the 24 V outputs are used, use one relay for each output and wire them in parallel to the M/A of the
DX module
WARNING : The 24 V and 0-10 C startup signals do not in any case control the anti-cycle safety function of the
direct expansion coil.

IV.15. Electric heater battery

The electric heater batteries are single-phase units on all the models in the range with the exception of the INFINITE BC
series 2000 and 2500, on which are they are three-phase units.
