IVAR.B4V - dependent el. 4-speed control

The IVAR.B4V category includes dependent electrical 4-speed controls designed for integration with two-pipe fancoil systems. These controls operate at 230V, 50 Hz and are used to regulate fan speed in response to temperature settings. They are typically used in HVAC systems where precise airflow control is required, such as in commercial buildings, offices, or industrial environments. The controls work in conjunction with compatible thermostats or controllers, such as the IVAR.TFM, or with third-party systems via higher-level control units.

How to choose

• Confirm compatibility with the fancoil model and control system in use.
• Verify the supply voltage (230V) matches the system requirements.
• Ensure the control is suitable for the intended number of fan speed levels (up to four).

Frequently asked questions

Can IVAR.B4V be used with non-IVAR control systems?
Yes, it can be used with other manufacturers' systems if a higher-level control unit is available to manage the fan speed settings.

What is the operating principle of IVAR.B4V?
It adjusts fan speed in four power levels based on the temperature difference between the setpoint and the actual room temperature, using signals from a compatible control unit.
