If you are connecting the FRISTAR3-WP 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
Mode of operation Through use of the instantaneous heating concept, drinking water is heated both hygienically and with low energy consumption in the FRISTAR freshwater station. If water is drawn from the mains, the primary circuit pump transports tank water from a buffer tank through the plate heat exchanger. -

Page 11: Connection Of A Circulation Line
Primary pump Circulation pump (optional) If an external DHW circulation pump is connected directly to the FRISTAR3-WP controller, it will op- erate in pulse mode. While water is being tapped, the circulation pump runs provided the temperature set at sensor T lies below the set temperature by the difference set with the potentiometer. -
Page 12: Cascade Switching
Cascade switching The FRISTAR3-WP is designed for a maximum water draw-off of 30 l/min. For a greater draw-off of domestic 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. -

If the DHW circulation pump is also to be switched on and off according to temperature, the maxi- mum possible number of FRISTAR3-WP modules is three. This is done using the program 480 for switching 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 22: 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.). -
