Primary temperatures: supply up to 130°C, return up to90°C.2. Secondary temperatures: supply up to 90°C, return upto 70°C.3. System provides a SSF temperature depending on theoutdoor temperature according to a reset schedule(Fig. 139).4. Heat demand dependent pump switching, with one fullcycle of the pump per day to prevent seizing.5. Diagnostic functions via connector.6. PRF temperature limitation with fixed and variable valueavailable. The control valve reduces the flow until the PRFtemperature is below the parameter value. The setpoint canbe fixed or floating with a certain ∆T below the PSF.7.
