RESOL - Model FK - Solid Fuel Boiler Controller
From Solar and Heating Controllers
The DeltaTherm® FK Solid fuel boiler controller has been especially developed for systems with solid fuel boilers, water heating stoves or pellet stove heating systems. With the integrated PWM outputs, the DeltaTherm® FK can manage the speed control of 2 high-efficiency pumps. With its easily configurable optional functions, the versatile software allows e. g. for the control of an electronic mixer for the return mixing function, a thermostatic backup heating, a target temperature control function and many more.
