26. FUNCTIONING FEATURES

26.1. SET POINT IN COOLING MODE

(factory set) = 7°C, ∆t = 5°C.

26.2. SET POINT IN HEATING MODE

(factory set) = 45v, ∆t = 5°C.

If the unit power supply is restored after a tempo

rary interruption, the set mode will be kept in the

memory.

26.3. COMPRESSOR START-UP DELAY

Two functions have been prepared to prevent

compressor start-ups that are too close.

− Minimum time from last switch-off 180 sec

onds.

− Minimum time from last switch-on 300 sec

onds.

26.4. CIRCULATION PUMP

The circuit board envisions an output for pump

management, which starts on commissioning and

remains on for at least 150 seconds and controls the

state of the probes.

After the first 40 seconds that the pump functions,

when the water flow rate is in normal working

conditions, the water flow rate alarm functions

are activated (differential pressure switch or flow

meter).

When the machine enters stand-by mode, the

pump remains on for 30 sec and controls the flow

meter or the pressure switch

26.5. FAN SPEED CONTROL

(DCPX ACCESSORY)

To allow correct functioning of the unit at different

external temperatures, the MODUCONTROL by

reading the pressure via the pressure probe, con-

trols the rotation speed of the fans, thus allowing

to increase and/or decrease heat exchange, keep-

ing the condensation or evaporation pressures

more or less constant. The fan functions independ

ently with respect to the compressor.

Remember that the DCPX is mandatory for the

production of DHW

26.6. ANTI-FREEZE ALARM

The anti-freeze alarm is never active if the machine

is off or in stand-by mode. In order to prevent

breakage of the plate heat exchanger due to freez-

ing of the water it contains, the MODUCONTROL

blocks the compressor and ignition of the resist

ance (ACCESSORY) if the temperature detected

by the probe positioned at the outlet of the heat

exchanger and in inlet to the chiller is below +4°C.

THIS ANTI-FREEZE SET TEMPERATURE CAN ONLY

BE VARIED BY AN AUTHORISED AFTER-SALES

CENTRE AND ONLY AFTER HAVING CHECKED THAT

THERE IS ANTI-FREEZE SOLUTION IN THE WATER

SYSTEM.

The intervention of this alarm determines com

pressor block and not pump block, which remains

active along with the switch-on of the resistance

if installed.

To restore normal functions the temperature of

the outlet water must rise above +4°C. Rearm is

manual.

WHENEVER THIS ALARM INTERVENES, WE

ADVISE YOU CALL THE NEAREST AFTER-SALES

SERVICE IMMEDIATELY.

26.7. WATER FLOW RATE ALARM

The MODUCONTROL manages a water flow rate

alarm controlled by the differential pressure switch

installed in series on the machine.

This type of safety device intervenes after the first

40 seconds of pump functioning, if the water flow

rate is not sufficient.

The intervention of this alarm determines com

pressor and pump block.

WARNING

Inspection, maintenance and

eventual repair work must be car-

ried out only by a legally qualified

technician.

Lack of control/maintenance can

cause damage to persons or things.

For appliances installed near to

the sea, the maintenance intervals

must be halved.

27. MAINTENANCE

All cleaning is prohibited until the unit has been

disconnected from the electric power supply mains.

Make sure there is no voltage present before

operating.

Periodic maintenance is fundamental to keep the

unit perfectly efficient under a functional and ener

getic point of view.

It is therefore essential to carry out periodic yearly

controls for the:

27.1. HYDRAULIC CIRCUIT

− Refilling of water circuit

− Cleaning the water filter

− Control of flow switch

−

Bleed the air from the circuit.

− Verify that the water flow rate to the evapora

tor is constant.

− Verify the thermal insulation of the hydraulic

piping.

−

Check the percentage of glycol where neces-

sary.

27.2. ELECTRIC CIRCUIT CHECKS

− Safety efficiency

−

Electric supply pressure

−

Electrical Input

− Connection tightness

− Verify the operation of the carter compressor

resistance

27.3. COOLING CIRCUIT CHECKS

−

State of compressor

− Efficiency of the plate heat exchanger resist

ance if envisioned

−

Work pressure

− Leak test for watertightness control of the cool

ing circuit

− Functioning of high and low pressure pressure

switches

−

Carry out the appropriate checks on the filter

dryer to check efficiency

27.4. MECHANICAL CHECKS

− Check the tightening of the screws the

compressors and the electrical box, as well as

the exterior panelling of the unit. Insufficient

fastening can lead to undesired noise and
