All FLOWAIR water heaters can be controlled by two control systems:
S -TYPE CONTROL
control of devices that operate in an ON/OFF system
M SYSTEM smooth rotational speed control of the fan
Water heaters with the M SYSTEM in standard version have been equipped with a controller built on the fan allowing smooth adjustment of airflow efficiency ranging from 0 up to 100%. This adjustment simultaneously regulates the heating power of the device. The use of this type of electronics (a controller with a continuously sampling temperature sensor) ensures the fan’s self-adjustment to current conditions. The minimal amount of heat required to sustain the desirable temperature is supplied this way (see the graph below). In addition, it increases heat comfort and reduces the noise level in the room being heated.
