Room temperature controller with solar control FR120 8737707188

Digital room temperature controller for all heaters with BUS-capable Heatronic 3 or analogue 1-2-4 interface.  The heating circuit temperature input provides for a continuous adjustment of the burner output to the required heat output. This allows for the individual adjustment of the heating system to daily temperature needs. Addionally, in conjunction with an ISM1 solar switch module the solar hot-water preparation can be optimised. FR120 provides a wekk programme, a hot-water programme with individually adjustable temperature levels in the time programme, a time programme for the control of a circulation pump, a holiday and a thermal disinfection function. Moreover, other heating and hot-water programme settings as well as display options can be adjusted. For quick comprehension, error and service codes are displayed in clear text. Thanks to the ex-factory pre-programming, the controller is instantly ready-to-use. The menu-guided clear-text display makes the operation particularly easy.
