Solid fuel boiler controller FK, with three sensors

• For solid fuel boilers
• For standard and high-efficiency circulation pumps with PWM signal
• With 4 inputs and 2 outputs

• The FK solid fuel boiler controller was specifically developed for systems with solid fuel boilers, water-bearing wood-burning stoves, or pellet heating systems. Its integrated PWM outputs allow it to control the speed of two high-efficiency pumps.

With easily configurable selection functions, the versatile software enables, for example, the control of an electronic mixer for return flow mixing, thermostatic reheating, target temperature control and much more.
