Wall-mounted heating controller DELTATHERM® FK

for boiler

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. 2 relay outputs, 4 temperature sensor inputs 2 PWM outputs for the speed control of high-efficiency pumps Control of an electronic mixer for the return mixing function Heating backup Heat exchange function Thermostatic backup heating Temperature sensor inputs:4 Sensor type:Pt1000 Semiconductor relays:2 Potential-free relay:- PWM/0-10 V outputs:2 Software Pre-configured systems:8 Mixed heating circuits:- Mixer control weather-compensated:- Mixer control with target temperature:check Operating modes:- Heating circuit antifreeze function:- Heating circuit chimney sweeper function:- Screed drying function:- Room thermostats:- Thermal disinfection:- DHW heating:check Circulation:- Solid fuel boilder:check Heating circuit return preheating:check Return mixing function:check Thermostatic afterheating:check Weather-compensated afterheating:- Night correction:- Boiler protection:check Start-up/Overrun:- Afterheating suppression:- DHW priority:- Heat exchange:check Mixer:check Parallel relay:- Irradiation switch:- Error relay:- Function block:- Zone loading:- HQM:- 0-10 V boiler control: Room control: Remote access with VBus®Touch HC:
