Broag Pressurisation equipment Compact wall mounted and free standing pressurisation units, utilising the latest microprocessor control. For use on sealed heating and cooling systems, offering accurate control and reliability. Digital equipment comes with a 4 digit bright LED display with scrolling messages including pump operation and alarm modes. Single or twin pump configurations. Complete with integral water break tank utilising an AB airgap and a WRAS approved float valve. Twin pump equipment operates as cyclic duty standby with automatic changeover. Internal alarm with mute function. Security password protected. Auto resetting low water detection, for pump protection. Auto resetting high and low pressure alarm. Digital pressure setpoint with adjustable differential. Flood protection through a pump run limit timer. Normally closed, common fault, volt free contact (Boiler interlock). Normally open, individual volt free contacts for pump trip, high pressure, low pressure and sensor health.

Wiring details for all Digital Pressurisation Units Supply Voltage 30- v- Single Phase. Fuse Rating - 5 Amps Max Full Load Current - 4.5 Amps Under normal operation there is a permanent live feed back to the boiler, the water temperature is regulated by the operation of the motorised valve feeding the internal coil. To control the heating times, connect the electrical feed to the thermostat from the program or time clock (L). When the Remtank Calorifier is at the desired temperature, the motorised valve will close and the boiler, itself, will register no demand from the cylinder and shut down if appropriate. Note: Control of hot water via Rematic 945ck and Broag Priority Kits. When using the Rematic 945ck controller and Broag Priority Kits in conjunction with the supplied HWS immersion sensor, fit the supplied brass pocket in the secondary return connection and connect immersion sensor into pocket, the secondary return connection should then be connected into the cold feed supply at the base of the calorifier between the safety group and the calorifier. Sensor wiring connections can be found in the boiler control wiring details. The port valve must be wired as detailed in the diagrams above, with the electrical supply coming from the Priority Kit/Boiler controls. To ensure the correct operation of the Priority Kit set the control thermostat (connected to the port valve) 0 o C higher than the boiler or controller hot water temperature. 3
