Page 4: Safety Instructions
If you are connecting the FRISTAR3 to an electrical system via a residual current device (RCD), use an RCD of type A which will detect pulsating direct currents and bears the following marking: Checking using a high voltage insulation tester may cause damage to the pump and the control elec- tronics. -
Page 5: Mode Of Operation
The cooled tank water is returned to bottom layer of the buffer tank. The speed control of the primary circuit pump takes place in the FRISTAR3 controller based on the readings from the volume flow sensor in the hot water line (flow rate VWW and temperature TWW) and the temperature sensors in the cold water line (TKW) and the primary flow (TPri). -

Page 7: Installation
Installation Preparation • A safety valve (max. 6 bar) must be installed in the cold water supply corresponding to stand- ards DIN 1988 and 4753, part 1 and TRD 721. • If the cold water pressure > 6 bar, fit a diaphragm pressure reducer max. 6 bar. •... -

Page 9: Interchanging Connections
Interchanging connections For optimum matching of the pipelines to the freshwater station it is possible to interchange the con- nections (right/left). This does not change venting of the primary circuit, however. Version Version „Pump right“ „Pump left“ Pump connection-plug Procedure: 1. -

Page 11: Connection Of A Circulation Line
Primary pump Circulation pump (optional) If an external DHW circulation pump is connected directly to the FRISTAR3 controller, it will operate in pulse mode. While water is being drawn off (once or continually), the DHW circulation pump runs until the temperature at sensor T... -
Page 12: Cascade Switching
Cascade switching The FRISTAR3 is designed for a maximum water draw-off of 30 l/min. For a greater draw-off of do- mestic hot water, multiple freshwater stations can be used in a cascade. The first module is fed directly, all others stations are added with stop valves, if necessary. These valves must open or close in at least 30 seconds. -

Page 15: Schematic Diagram For Activating The Dhw Circulation Pump With A Different Switching Device
If the DHW circulation pump is also to be switched on and off according to temperature, the maxi- mum possible number of FRISTAR3 modules is three. This is done using the program 480 for switch- ing modules 2 and 3 on and off via outputs A1 and A2. The DHW circulation pump can be switched at output A3 via the differential S5 –... -
Page 16: Data Transfer With Cora-Dl
The FRISTAR3 controller has a connection for CORA-DL (electrical connection on page 19). This makes it possible to read out and preset various values. Datalogging of the values is also possible. To work with CORA-DL, the CORA device FRISTAR3 is used on the freely programmable controller. Input variables Set temperature [°C]... -
Page 17: Status
DL bus The address is set with DIP switches on the PCB of the FRISTAR3 controller, which are labelled 1, 2 and 4. These are located on the outer edge of the PCB. If the DIP switches are not in the ON position, address 1 is assigned to the FRISTAR3 controller (factory setting). -
Page 18: Index
Index DL inputs A value can be read out from the FRISTAR3 controller via a DL input on the controller. The index of each value is fixed: Index: Measurement: Actual DHW temperature T [°C] Cold water temperature T [°C] Flow rate [l/h] Primary temperature T [°C]... -
Page 19: Electrical Connection
The polarity of the DL bus connections (DL and "Earth") is not interchangeable and must be observed. Safety instructions If you are connecting the FRISTAR3 to an electrical system via a residual current device (RCD), use an RCD of type A which will detect pulsating direct currents and bears the following marking: Checking using a high voltage insulation tester may cause damage to the pump and the control elec- tronics. -

Pump LED Temperature selection Manual/automatic switch The temperature can only be selected on the FRISTAR3 controller if no set value has been issued by a freely programmable controller (e.g. UVR16x2) via the DL bus. Manual-automatic changeover switch AUS (off) The pump is permanently off and the valve is closed. -

LED status displays In the following, all possible status display of every LED is listed, in descending order of priority. Only topmost (= highest priority) active status will be displayed. The LED will flash in the presented colours from left to right and then repeat the process of as long as the corresponding status (and no other status with higher priority) is active. -

Page 23: Pressure Loss Characteristic Curve Plate Heat Exchanger
Pressure loss characteristic curve plate heat exchanger Pump curve (1 kPa = 10 mbar) The pump operates in heating mode, meaning that at a 5 % PWM value, the pump will run at full speed. A break in the PWM lead therefore results in full pump speed. The eight curves shown correspond to the following PWM values: 5 % (max.), 20 %, 31 %, 41 %, 52 %, 62 %, 73 %, 88 % (min.). -
