About the product
“Triple control, cutting-edge technology”
OCV3 Version 1 Window Regulator
Electronic device designed to open or close air inlets / windows / dampers, etc.
Manages 3 OSMO lift motors.
Digital temperature probe included (1 per motor).
Motor 3 recommended for chimneys or ridge vents.
Multiprogram microcontroller (since July 2024).
Able to adapt to different types of installations.
Natural ventilation (With our digital temperature probe)
Temperature control from 0ºC to 85ºC with 1ºC hysteresis.
Easy programming and reading of limit switches and control and operating parameters: temperature, battery voltage, window position, maximum opening and minimum closing, etc.
Fault detection system and parameter storage during power outages.
Programmable thermal jump detection (recommendation: NOT LESS THAN 2º).
– Motor 1 and 2: emergency priority command: programmable window positioning with an external device and our auxiliary input.
In the absence of 230 V: we take control by temperature.
– Motor 3: recommended for chimneys or ridge vents.
In the absence of 230 V: two options, take control by temperature or emergency opening
Forced ventilation (in addition to the previous operation):
Motor 1 and 2:
– By adding our CVA* accessory (DP3 PROGRAM) and using the digital temperature probes already installed in our regulator, we activate the connection and disconnection of external devices for: ventilation, cooling, heating, or any type of device.
– Programmable emergency temperature.
Motor 3:
– Different operating possibilities. In the absence of 230 V, two options: take control by temperature or emergency opening.
