Instruction Manual for Streamline Heatwave Thermo 2-D Hot Water System

Quick Guide

The Streamline Heatwave Thermo 2-D is a hot water system designed for window cleaning. It utilizes diesel fuel and a 12V power source. The system is controlled via the SFC6 Red Thermo Controller. Key operational steps include ensuring the controller is switched on, activating the heater, and monitoring the system for error messages.

Operating the System

To operate the Thermo 2-D, ensure the SFC6 Red Thermo Controller is switched on and the Heater Setting is enabled:

• Activate Heater: Press the up and down arrows together for 2 seconds. When 'HTR' appears on the screen, press the up arrow to switch it on and the left arrow to set.
• Start-up: With the vehicle engine running, turn the Thermo 2-D on using the left-hand switch on the front cover. Allow the heater to warm up for approximately 10 minutes.
• Water Pumps: Switch on the pure water pumps using the arrow on the controller.
• Cold Weather Use: If operating in temperatures below 10°C, it is advised to run the system on a colder setting to prevent damage to glass. This is activated by the right-hand Red Toggle switch on the front cover.

Anti-Frost Mode

The system includes an anti-frost mode to prevent freezing:

• Press the up and down arrows together for 2 seconds to enter the menu.
• Scroll using the left arrow until 'FST' appears.
• Press the up arrow to switch it on and the left arrow to set.
• Set the pump speed (normally between 10-20) and press the left arrow to set.
• If the water temperature drops below 2°C, the pump and heater will automatically activate for 13 minutes. Ensure the hose is attached to the tank return for this to function.

Dead-End Detection

This feature prevents pressure build-up and hose damage by shutting down the pump when flow is stopped (e.g., kinked hose or removed pole).

• Calibration: Press and hold the up and down arrows simultaneously until 'Cal' displays.
• Adjustment: While 'Cal' is displayed, use the up arrow to decrease sensitivity (turns off at higher pressures) or the down arrow to increase sensitivity (turns off at lower pressures).
• Save: Press the Enter button to save the setting.

Troubleshooting Messages

The controller displays specific codes to indicate system status:

• dE: Dead-end detected; pump turned off automatically.
• PS: Pressure switch activated; reduce pressure to restart.
• Bat (Pump working): Battery voltage below 11.5V; recharge as soon as possible.
• Bat (Pump stopped): Battery voltage below 11.0V; pump stopped to protect battery. Recharge immediately or start the engine if a split charge relay is fitted.
