Ventil 1D

It is a control for fancoil, equipped with the powerful ARM Cortex-M0 processor, a breakthrough in technology and 32-bit architecture.

Thanks to its advanced technology, it generates a high efficiency and achieves a low power consumption of the installation, with maximum comfort level.

Installing a 1D Fan achieves optimized management of the processes of activation / deactivation of the air conditioner that provide a considerable greater savings, up to 30% savings compared to other thermostats on the market.

With a larger opening at the back, that is to say, more space for better wiring.

You have the possibility of an optional remote probe. Switching from winter mode to summer mode by master wire.

Technical Characteristics

• Power supply 90Vac…250Vac 50/60Hz
• Internal temperature sensor with scale from 0 to 50°C
• Heating and cooling differential of 0.5°K
• Display 26 x 12.5mm
• Fan speed adjustment by switch (1, 2, 3 or automatic)
• Neutral Zone adjustable in 2K or 4K
• User adjustable range 5°C to 30°C ( 41°F to 86°F)
• Internal temperature sensor with scale from 0 to 50°C
• Heating and cooling differential of 0.5°K
• 5A relays
• Measures 125 x 77 x 35mm ( 4.92 x 3.03 x 1.41 inch )

Operative

• Digital control of fan speeds and Stop/Start
• Power supply according to model 90Vac…250Vac 50/60Hz (code 10.269) or 24Vac 50/60Hz (code 10.270)
• The display in the stop position indicates OFF. In operation it indicates the temperature (running) and speed 4 digital buttons. Without mechanical switches
• Temperature in °C (Celsius) or °F (Fahrenheit)
• Switching on and running
• Regulates the local or remote ambient temperature
• Suitable for both heating and cooling installations
• Centralised control of the changeover Remote heating / cooling per built plant (or sector) via additional input for an external switch
• Manages installations with both 1 and 2 valves without the need for programming, by means of microswitches, (2 or 4 tubes respectively)
• Fan speed adjustment by means of selected scheme
• Automatic adjustment of the fan speed, according to how far the setpoint is from the detected temperature, the fan will be set to maximum speed, and will be reduced as it approaches the setpoint
• Indication for operation in heating or cooling mode
• Possibility to manually force ventilation, (switches off the ventilation linked to the thermostat)
• In Automatic position the fan works in thermostatic mode (linked to the thermostat)
• Thanks to the different relays, even if the thermostat is supplied at 90Vac…250Vac 50/60Hz, the fan can be of another voltage, both alternating and direct, the same applies to the valve
• The remote probe, overrides the interior of the thermostat
• In case of using the remote cool/heat changeover, it cancels the possibility for the user to put the device into cool/heat respectively, the remote contact commands the selected on the device.
• It is ideal for large installations such as hotels, since it is not necessary to make the changeover one by one.
• Card control: when you close the card contact (= empty room), the system switches to economy setting according to the position of the internal microswitch (in off heating = 18°C and cooling = 28°C, in on heating = 20°C and cooling = 26°C)
• Window control: when you close the window contact (i.e. the window is open) the system stops (therefore it goes to OFF, anti-frost setting)

Standard

External input for remote summer/winter changeover (diagrams 2, 3 and 4, terminal 1)

Optional

Remote temperature sensor Sonamb 201 PTC2000 (76 x 76 x 30mm) and the TA trim plate to be fixed on a Ø60mm (85 x 85mm) box and 3m double insulation PTC2000 D.A. probe, sensor measures 26mm x Ø 7mm.
