Accessories for Vaillant fan coils

Accessories for Vaillant aroVAIR fan coils complete the VA 2 CN range of sill-mounted fan convectors with the control and hydraulic components needed for full operation. Here you will find room controllers at various levels – from the simple analogue dial controller VA 1-WC DC through the electronic controller VA 2-WC C with 7 fan speeds up to the digital controller VA 2-WC D with a display and automatic Auto/Heating/Drying/Cooling/Fan mode.

In a two-pipe installation, where a single circuit alternately supplies both hot and chilled water, a kit with a 3-way diverter valve is also required; it switches between heating and cooling mode according to the controller's demand. For installations away from a wall or ceiling, the VAZ-015-070-F1 feet are used, allowing the fan coil to stand freely on the floor beneath a window (sill position).

Frequently asked questions

• Which controller should I choose? For the simplest operation the analogue VA 1-WC DC is sufficient, for more operating modes and finer fan control the electronic VA 2-WC C, and for comfort with a display and automatic operation the digital VA 2-WC D.
• When do I need a kit with a 3-way valve? In a two-pipe system, where switching between heating and cooling takes place at the heat/cold source and the fan coil must be able to have its circuit switched in a controlled way.
• Are the feet included with the fan coil? No, they are supplied separately and are needed only for free-standing (floor) installation instead of wall or under-ceiling mounting.
• Is this accessory compatible with all output series? The controllers are, but the kit with the 3-way valve and the feet are always tied to a specific output range of the fan coil – check compatibility in the product description.
