This Smart Controller is an additional controller, designed to fit our Bobil Hydronic Kits and is useful if you have multiple heat exchangers in different rooms, and are wanting thermostatic control over individual rooms.
 
The standard Smart Controller that comes with the Bobil Hydronic kit has space for 3 PWM fan wires, which will be enough for most van systems, but if you have a very large motorhome or horsebox with multiple rooms, or even a canal boat or other application where you'd require more than 3 fans or would like individual control over each room, then you'll need one of these controllers per room.
 
This Controller also has space for 3 PWM fan connections. It cannot control the diesel heater, only at which temperature the air matrix should turn on and off at to keep the room a stable temperature.
 
This kit contains only the controller, if you require extra air matrices, you can purchase those here.
