1. General Advice











1.1 Please Read Before Using This

Manual

This manual is part of the product and should be kept near the instrument for easy and quick reference.

The instrument shall not be used for purposes different from those described hereunder. It cannot be used as a safety device.

Check the application limits before proceeding.

1.2 Safety Precautions









Check the supply voltage is correct before connecting the instrument.

Do not expose to water or moisture: use the controller only within the operating limits avoiding sudden temperature changes with high atmospheric humidity to prevent formation of condensation

Warning: disconnect all electrical connections before any kind of maintenance.

The instrument must not be opened.

 In case of failure or faulty operation send the instrument back to the distributor or to “Dixell s.r.l.” with a detailed description of the fault.







Consider the maximum current which can be applied to each relay (seeTechnical Data).

Ensure that the wires for probes, loads and the power supply are separated and far enough from each other, without crossing or intertwining.

Fit the probe where it is not accessible by the end user.

 In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel with inductive loads could be useful.

Full Manual

Dixell S.r.l. reserve to itself the right to modify this instruction manual without any warning.

Analog Inputs

Pressure or temperature analogue input functioning

0 = Temperature / pressure NTC – 4÷20 mA :

The condensing temperature is controlled with NTC probe while for the evaporating pressures of the circuits 1 and 2 and the pressure probe configured as auxiliary output 1 and 2 are controlled with 4÷20mA transducers.

1 = Pressure control with 4÷20 mA:

To control the evaporating and condensing pressures it is necessary a 4÷20mA transducer.

2 = Temperature / pressure NTC – 0÷5Vdc:

The condensing temperature is controlled with NTC probe while for the evaporating pressures of the circuits 1 and 2 and the pressure probe configured as auxiliary output 1 and 2 are controlled with 0÷5Vdc transducers.

3 = Pressure control with 0÷5Vdc:

To control the evaporating and condensing pressures it is necessary a ratiometric 0÷5Vdc transducer.

Anti-freeze alarm delay in HP for low outlet air temperature

(air/air)

Attention

If during the Stand-by or remote off there is an anti-freeze alarm event, and the AL35 <>0, starting the heat pump mode, from keyboard or digital input. In this case the anti-freeze alarm is aborted and the compressor starts for the AL35 time to heat the air or the water.

After the AL35 time if the antifreeze probe value is still lower than

AL33 setpoint, for maximum AL36 seconds, the unit is stopped and the anti-freeze alarm is generated again.

Anti-freeze alarm delay for low air ambient temperature or low outlet air temperature in heat pump normal condition.

The detected temperature must be lower than AL33 for the time
