TECHNICAL DATA AND FUNCTION OVERVIEW

• 7 relay outputs and 10 inputs for Pt1000, Pt500 or KTY temperature sensors
• Up to 3 extension modules via VBus
• Inputs for analogue Grundfos Direct Sensors™ as well as for FRH humidity sensors
• Integrated control of up to 4 high-efficiency pumps via PWM outputs
• Data logging, storing, easy transfer of controller adjustments prepared and firmware updates
via SD card
• Cooling over the heating circuit with condensation detection
• Dew point calculation by means of the FRH humidity sensor to avoid condensation
• Simplified timer, 0-10 V boiler control and DHW preheating
• Remote access to the heating circuits with room control unit(s) or the VBus
• Extended optional functions, e.g. solid fuel boiler function with mixer and target temperature
control
