IVAR.B10 control for IVAR.FARNA, BIG fan coils – control board for 0–10 V thermostats, 230 V – SALE
Code: B10042IIRelated products
Product detailed description
The IVAR.B10 board, code B10042II, is a dependent control for IVAR.FARNA and IVAR.FARNA BIG fan coils in a two-pipe system. Fitted inside the unit, it drives the DC Inverter fan motor in modulating mode – the speed follows the 0–10 V analogue signal from the connected thermostat or a higher-level control system without steps. Without one of the recommended controls the fan coil will not operate.
How the board responds to the signal
- below 1 V DC the fan motor is off,
- from 1.1 V to 10 V DC the speed rises linearly from 400 to 1500 rpm,
- the Y1 output, 230 V / 50 Hz, 1 A, for the electrothermal actuator switches on above 1 V and off below 0.9 V.
Several units on one signal
The analogue input has an impedance of 25 kΩ. Take this value into account when choosing the controller output, especially if one signal is to drive several fan coils connected in parallel.
Control and signalling
As a signal source the manufacturer names the IVAR.TFZ01M thermostat; the board also suits higher-level smart home systems. The LED stays off with a signal below 0.9 V, lights during normal operation above 1 V and reports a motor alarm with a double flash, for example when the fan is blocked by dirt or the speed sensor fails. Power supply is 230 V / 50 Hz; connection should be left to a qualified electrician.

Frequently asked questions
Which controller connects to the B10042II board?
A thermostat or control system with a 0–10 V analogue output, for example the IVAR.TFZ01M thermostat or a smart home management system.
Can one 0–10 V signal control several fan coils?
Yes, the boards can be connected in parallel. However, the 25 kΩ input impedance of each board must be taken into account and the controller output chosen accordingly.
At what voltage does the fan stop?
Below 1 V DC the fan motor is off. Between 1.1 V and 10 V the speed rises linearly from 400 to 1500 rpm.

IVAR designs, develops and manufactures highly energy-efficient heating and plumbing systems. We have over 10,000 catalogue items - mass-produced products and unique items - in addition to customised systems and combinations of complex products. And it’s all “Made in Italy”.
Vision
To make life easier for our clients, our clients' customers and our employees, thanks to our ability to be constantly innovative.
Mission
To design and manufacture advanced hydronic solutions that reduce installation complexity and energy consumption.
“Made in Italy” adds value
IVAR has been producing heating and plumbing system components since 1985: valves for heating bodies, direct heat metering modules, heat cost allocators, pipes and fittings, substations for heating systems, distribution manifolds, radiant panel systems, and components for solar and geothermal systems. And it’s all “Made in Italy”.
Over 200 people are employed at our manufacturing facilities in Prevalle (in northern Italy’s Brescia province). The site has been designed to streamline our many production and operational stages.
The Italian headquarters also acts as a hub for the wider IVAR Group, set up with the goal of distributing products beyond Italy’s borders. The group now has 11 branches, in Australia, Belgium, China, Germany, the United Kingdom, the Czech Republic, Romania, Slovakia, Spain, the United States and Tunisia.
Know How
Research, development and numerous laboratory tests guarantee that our clients’ requests can be translated into new high-efficiency products.
The stages required for production take place internally, beginning with hot forming, which is carried out at our subsidiary Valmon Stampati. Our continuous implementation of projects under the Industry 4.0 initiative also allows us to take full advantage of new releases in technology and IT to improve our manufacturing efficiency.
As a company, IVAR is constantly evolving. Every day, we invest in strengthening our products, in improving our production processes and in attaining new patents and certifications.
