Pressure Safe System Pressure Release Valve Safety System Safety first The pump collects condensates. Thanks to the diffuser reducing the pressure, it also allows the safe discharge of the pressure relief valve inside the property. The pump safety switch can detect if filling loop is left open, or a failure of plate-to-plate heat exchanger, or a failure of the pressure release valve. If a failure occurs, the pump sends a signal to the regulation box. The regulation box closes the solenoid valve and stops cold water entering the boiler. The heating stays on, hot water is stopped. A red light is activated informing the end user he must call contractor to solve the problem and reset the installation. AVANTAGES ● Safe installation - No risk of house floods. - No risk of heating system shutting down due to frozen PRV discharge pipes. - Notices failures and informs when contact with the contractor is needed. ● Easy and quick installation - No long expensive copper pipe runs. - No ladder work, no drilling through wall ● Preserve the environment - No water loss. - No energy loss.
