- Page 2 1. Introduction CSE SOL G SRS1 T-K Solar Pump Station is fitted with a solar pump of the latest generation that permits flow control either internally by selecting a suitable mode or externally through PWM signal. The complicated setting of the right flow rate is not needed when the PWM signal is used, the pump station keeps adjusting it automatically, depending on the actual solar radiation.

Page 5: Check Valve
4.1 Check Valve The non-return valve prevents the tank from cooling down due to gravity circulation when the sun is not shining. It is located between the ball valves and can therefore be removed and cleaned without having to drain the solar fluid from the entire circuit. If the mark is on the left, the check valve is set to the position for normal operation. -

6. Installation Options The solar pump station is designed to be mounted on a wall or on a tank. There are two fixing ope- nings in the rear part of the insulation. The lower one is accessible only when the electronic contro- ller is removed from rear part of the insulation (see the pic. - Page 7 7.1 Overview of Hydraulic Variants...

8. UPM3 HYBRID 25-70 Pump Pump control The circulation pump can be controlled: • internally without PWM signal by selecting a proper mode and pump curve. • externally by PWM C control signal (profile for solar systems) WARNING – IMPORTANT The pump permits to be controlled also by PWM A signal (profile for use in heating systems). - Page 9 Description of Pump Frofiles a) INTERNAL CONTROL - Proportional pressure • Head (pressure): reduced with growing system pressure drop and increased with sinking system pressure drop. • Pump operating point: moves up or down on the selected proportional pressure curve depending on the current system pressure drop.
