OPERATION

OMNIA UL PC fancoils are delivered ready to operate

in standard configuration, though can be adjusted by the

installation technician to specific requirements by means of

dedicated accessories and configuration of functions at the

internal dipswitches (see DIPSWITCH CONFIGURATION).

Response to controls is immediate, except in special cases.

Unit types

OMNIA UL PC fancoils are designed for twin-tube units, in

the following types:

- without valve;

- with 2-way valve (water probe below valve);

- with 3-way valve (water probe above valve).

Ventilation

Ventilation speed can be controlled either manually by set-

ting the selector switch A to position V1, V2 or V3 (the fan

operates in on-off cycles according to the speed selected),

or automatically when the selector switch is set to the AUTO

position (fan speed is controlled by the thermostat according

to room temperature detected).

On systems with a valve (dip1 = ON) and a Water Probe

installed upstream of the valve (dip2 = ON), a delay (maxi-

mum 2'40'') can be set between the valve switching on and

the fan starting up (pre-heating of the heat exchanger).

Ventilation can only take place with the louvers open. On

models where the louvers are not motorised these must be

opened manually.

Season changeover

The thermostat changes seasonal operation automatically.

Season changeover takes place according to the water tem-

perature detected in the unit.

According to the dipswitch settings, two types of season

change (water side) are possible:

- Dip1 = OFF, Dip2 = OFF (standard configuration) with

minimum/maximum temperature control only;

- Dip1 = ON, Dip2 = ON (configuration with three-way

valve and probe before the valve) with minimum/maximum

temperature control and coil preheating (fan operation delay

maximum 2'40").

n the case of special units with water probe below the valve

or fitted with 2-way valve, season change takes place from the

air side, through operation of the temperature selector switch.

Though this setting allows use of the fancoil in pre-existing 2-

way valve plants, it is not recommended, given that it hampers

the operation of the electronic thermostat (the Heating/Cooling

mode status display by LED is altered, depending on the tem-

perature selected and the room air temperature).

Water temperature controls

The thermostat only enables fan operation when the water

temperature is suitable for Heating or Cooling mode.

Both the hot and cold starting up temperatures can be set to

suit the conditions under which the system operates.

The hot starting up threshold can be selected using Dip 5:

OFF position for normal Heat (39°C) and ON position for

reduced Heat (35°C).

The cold starting up threshold can be selected using Dip 6:

OFF position for normal Cold (17°C) and ON position for

reduced Cold (22°C).

If the water temperature is not suitable for the operating

mode selected, LED lamp C on the control panel flashes

alternately pink, red and blue next to the relative mode; this

display is switched off when Dip1 = ON and Dip 2 = OFF.

Valve control

La valvola può essere controllata in due modalità:

- optimised: this mode exploits the capacity of the fancoil

(Heating) to supply heat even when fan operation has been

shut down; during Cooling, ventilation continues for control

of room temperature by the valve.

- normal: the valve opens or closes, depending on whether

the fan starts up or shuts down.

Probe correction

The required correction to be applied to the ambient probe

can be selected.

Frost Protection

This function prevents room temperature from dropping

below an ambient temperature of 7°C (even when the fan-

coil is off and selector switch A is in the OFF position).

In the event that room temperature drops below 7°C, the

thermostat starts up the fancoil in heating mode at a tem-

perature setting of 12°C and fan operation set to AUTO (if

permitted by water temperature, the unit is connected to

the power supply and the louvers are open, in the case of

manual units).

Frost protection mode is deactivated when room temperatu-

re rises above 9°C.

Emergency mode

In the event of failure of the SA ambient sensor, the thermo-

stat goes into Emergency mode as indicated by the yellow

LED (D) flashing. Under these conditions the control panel

operates in the following way:

- with selector switch (A) in OFF position: la valvola acqua è

chiusa ed il fan off.

- with selector switch (A) in AUTO, V1, V2 or V3 position: la

valvola acqua è sempre aperta ed il the fan performs on-off

cycles; in this case, the power supplied by the terminal is

controlled manually by means of the temperature selector

switch (B): rotate the switch to right to increase cycle dura-

tion, or to the left to reduce it.

Plasmacluster

The Plasmacluster air purifier is activated at the same time as

the ventilation whether hot or cold.

The functioning of the device is indicated by a yellow Led

coming on the control panel.

The Plasmacluster purification breaks down the water and

oxygen molecules normally present in ambient air ("damp-

ness" and "oxygen"), into positive and negative ions. These

ions liberated into the air will stick to the molecules of the

polluting substances and by being recombined (once activa-

ted) decomposes them into non-toxic sub-products (water,

oxygen and carbon dioxide etc..).

PACKAGING

The fancoils are sent with standard packaging consisting of

protective shells and boxes.

INSTALLATION OF THE UNIT

WARNING: before carrying out any work, put the proper

individual protection devices on.

WARNING: before carrying out any work, make sure the

electrical power is unplugged.

CAUTION: electrical connections, the installation of the

fan coils and their accessories must only be carried out

by people with the proper technical and professional qua-

lifications for the installation, conversion, expansion and

maintenance of the machinery and able to check that it is

working properly and safe.

Install the fancoil in a position that will facilitate routine

(filter cleaning) and special maintenance, and easy access

to the air breather valve on the side of the unit (connections

side).

Note that certain operating conditions could lead to the for-

mation of condensate on the unit housing with subsequent

dripping, or faults to the water circuit or condensate draina-

ge could cause liquids to overflow. For these reasons, avoid

installing the unit on surfaces damageable by moisture.

Make sure that the unit is installed in a site where the

ambient temperature is inside the minimum and maximum

limits 0 - 45°C (<85% R.H.).

To install the unit, proceed as follows:

- Remove the cover by unscrewing the screws in the head

piece under the doors.

- In the case of wall mounting, ensure a minimum distance

of 80 mm from the floor. For free-standing installation on

feet, refer to the instructions provided with the unit.

- Use expansion plugs (not supplied) when mounting the
