REMOTE MANAGEMENT
DIAMIX PR
and
COMPAMIX PR
are equipped with a MODBUS RTU interface; using the RS485 serial connection, it is possible to modify all the operating parameters, send commands to the valve, receive in-
formation on the operating status and perform diagnostics.
The
DIAMIX PR / COMPAMIX PR
mixing valves can be connected to the modern Building Management Systems (BMS).
TECHNICAL FEATURES OF THE ACTUATOR

Tracking cooling adjustment
The delivery temperature Tset_point for cooling is automatically calculated by the software as a function of the dew point temperature. The dew point temperature is calculated by means of the relative humidity
and ambient temperature sensor (optional cod. RFTRUEE10).
T_setpoint = Tr CI3 where:
Trujade = Dew temperature calculated from relative humidity and ambient temperature.
CI3 = temperature constant adjustable between -3°C and +3°C.
The function also regulates the relative humidity in the environment: the dehumidifier can be activated by means of a digital output when the relative humidity falls below the “CI1” threshold. Thanks to the special
digital output it is possible to activate the integration mode of the dehumidifier: When the ambient temperature exceeds the value “CI2”, the contact is closed so that the dehumidifier injects dry air into the house
at a temperature lower than the ambient temperature.
Electronic security:
It is possible to set two limit temperature for the fluid: one for winter heating and one for summer cooling.
P3 = heating mode max temperature, adjustable between 50°C and 60°C
P4 = cooling mode min temperature, adjustable between 5°C and 13°C
When these values are exceeded, the mixing valve enters the “safety” mode: it stops the pump and connects the common (mixed) way to the system return and then blocks any active function.
The display alternatively shows the "ALt" notice and the real-time temperature detected by the outlet sensor.
The system resumes normal operation only when the temperature is back within the normal operation range.
