1. GENERAL DE CRIPTION
The
DIAMIX - COMPAMIX - COMPAMIX e DIAMIX L - COMPAMIX L series valves are motorized
mixing ball valves consisting of ball valve and actuator.
CAUTION
ixing-thermoregulating valves must be installed by qualified personnel according to the specifica-
tions of this manual, in compliance with local standards and IEE regulations. COMPARATO will not be
held responsible for any problems arising from the non-compliance with these instructions. Before
the assembly, the installer shall read the instructions carefully. The manufacturer shall not be held lia-
ble, both contractually and non-contractually, for any damage to people, animals or things arising
from the misuse or from any mistake made during the installation or special maintenance. Likewise,
no liability shall derive from any operation performed by unqualified personnel and from all actions
infringing the provisions for the operation and laying instructions.
CAUTION! Risk of short-circuit or damage to the device! Before performing any operation, discon-
nect the power supply. The supply network must be disconnectable by means of a magnetothermic
switch and secured with a residual current-operated circuit breaker. This device must be protected by
an earthing equipment.

U E OF DIAMIX-COMPAMIX
ixing/thermoregulating valves are specifically used for:
• sanitary hot water mixing with recirculation system
• underfloor heating system
• under-bench heating system in greenhouses
• thermoregulations in general
U E OF DIAMIX L - COMPAMIX L
ixing/thermoregulating valves are specifically used for mixing hot sanitary water in systems where
a programmed thermal disinfection of the circuit is needed, in order to significantly reduce the pre-
sence and proliferation of legionella bacteria.
Thermal disinfection is compliant with what stated in national guidelines for the prevention and con-
trol of the Legionellosis.
N.B.: The multiple variables connected to the realization of plants where this equipment can be instal-
led are so numerous that it is impossible to totally exclude the risk.
NOTE ON OPERATION: fo DIAMIX - DIAMIX L and COMPAMIX - COMPAMIX L to ope ate co ectly
with plumbing and sanita y fittings, the use of eci culation loop is essential.

3.2. ACTIVATION
3.1. ELECTRICAL CONNECTION
Before making the electrical connections the supply power must be properly disconnected. To make
the connections, it is not necessary to remove the actuator cover: just connect the preset power chord
to the mains.
PHASE – brown • NEUTRAL – blue • GROUND – yellow/green
CAUTION: THI DEVICE MU T BE PROTECTED BY AN EARTHING EQUIPMENT. The earthing wire connec-
tion shall be secured in order to avoid accidental disconnections. The electrical installation shall be perfor-
med only by qualified personnel and according to current standards.
When the equip-
ment is powered,
the installed soft-
ware version is
shown on the
display for a few
seconds.
Immediately afterwards, if
the equipment was "off" the
last time it was powered
(default condition at the time
of purchase), the “OFF” mes-
sage appears. To turn it on,
press the “ON/OFF” button
once: the display will be
similar to the one described
in the following step.
The display shows the temperature measured by the probe; the mixing valve
is working. In case of power shortage, no operator action is needed when
the power is restored: the mixing valve starts working again according to
the last settings. In order to turn it off, press the “ON/OFF” button: if the
equipment is still powered, the “OFF” sign will appear.

TEMPERATURE REGULATION
To change the set temperature, press either the “A” or the “B” button: the
display will show the chosen value. Press “A” to decrease it or “B” to
increase it. During this step, the displayed number blinks. Adjustment
range: -15 / +85 °C.
Then, press “ENTER” or wait for 20 seconds in order to set the value. The
device starts working again automatically.

To reset the alarm (3digital outlet activation, optional), turn
the device off and then on again with the “ON/OFF” button.

set the value. Press “ENTER” to save the value and exit the
sub-menu. The adjustment range is from 2.0 sec. to 10.0 sec.
(default, 3.0 sec).
P2 MMM Indicates the number of minutes after which the "set tempera-
ture not reached” alarm is triggered. Press “A” or “B” to set
the minutes; if the value is P2=0, the “set temperature not
reached” alarm is disabled. Press “ENTER” to save the minutes
value and exit the sub-menu.

WARNING
The total cable length shall not exceed 30 meters.
NOTE:
In floor heating systems it is advisable to use the digital inlet 3– forcing towards cold – in order to
position the mixing valve passageway towards the return to the floor heating system when the circu-
lation pump stops.
This configuration prevents any high-temperature peak in the radiating panel circuit when the pump
is restarted.

4.1. DI INFECTION CYCLE OPERATION
DIAMIX L and COMPAMIX L deal with the thermal disinfection cycle of the recirculation ring of the
DHW distribution plant, as per the national guidelines for the prevention and control of the
Legionellosis. Disinfection timing and modes are automatically set on the basis of the user's needs
and the plant's features.
Programming is realised through a display and a keyboard; the cycle can be activated once a week
or on a daily basis. The user will have to program hour and day of disinfection cycle's repetition ( if
weekly programmed).
During the disinfection process, the temperature control is disactived and the valve is oriented
towards the hot water inlet; the water's temperature reading is realised by the second temperature
probe ( Legionella probe on sanitary circuit), the pump relay is triggered ( optional) and activated by
the Disinfection Cycle digital outlet ( optional).
CAUTION
During the disinfection cycle the hot sanitary water supplied to users can reach dangerous tempera-
tures which could cause scalds. Set the time and day of disinfection when it is unlikely that someo-
ne needs to use hot sanitary water.
During the cycle, the display toggles between the “SAni” message, the water temperature detected
by the legionella probe “C XX” and the progress percentage of the disinfection cycle “P XX”. The dura-
tion of the disinfection cycle will depend on the hot water temperature reachable by the system: the
higher the temperature, the shorter the cycle.
The disinfection can be programmed once a week.
The following table shows the cycle duration depending on the temperature:
If during the disinfection cycle the water is not hot enough (temperature below 55°C for more than
60 minutes), the "disinfection cycle temperature too low" alarm is triggered, the cycle is aborted, the
valve returns to the mixing mode and the display toggles between the "AL bt" message and the tem-
perature detected by the mixing probe.
In case of power shortage, the “power shortage during disinfection cycle” alarm is triggered, the cycle
is aborted, the valve returns to the mixing mode and the display toggles between the “AL d” messa-
ge and the temperature; the 2digital outlet “Disinfection alarm” is triggered (optional).
The maximum duration of the disinfection cycle is 5hours; if the cycle is not over after the afore-
mentioned amount of time, the actuator goes back to its thermoregulating function, the “Disinfection
cycle duration time exceeding 5hours” alarm is triggered and the display toggles between the “AL
ot” message and the temperature.

In order to achieve the correct positioning of the Actuator on the ball valve, please proceed as follows:
- Get the Actuator on the "completely hot" position ( flashing red led)
by setting the set point temperature on a higher value than the probe's temperature
- Wait for the achievement of the limit switch.
- If necessary, turn the ball valve's control rod until the notches on the rod are as in the picture:
