The Davies Craig Gen II Digital Thermatic EWP / Fan Switch lets you automatically switch electric cooling fans or an electric water pump on and off at your chosen coolant temperatures. You can set the switching temperature from 5-110°C using the controls on the unit, with dual relay outputs providing independent dual fan operation.The key features provide practical control over your electric cooling system:Adjustable 5-110°C Switching Temperature: You can select your required switching temperature using the button on the front of the unit, allowing your fan or electric water pump to operate automatically when the set coolant temperature is reached.5-Second Twin Fan Start-Up Delay: When controlling twin cooling fans, the switch delays the second fan by five seconds after the first fan starts, providing staged fan activation and helping your cooling system respond to rising coolant temperature.Dual Manual Override: Manual override functionality lets you switch your fans or electric water pump manually when required, giving you direct control independently of the automatic temperature switching.Digital Temperature Display: A large digital display provides clear coolant temperature readings in °C or °F, helping you monitor temperature and set the required switching point directly from the unit.IP67-Rated Housing: The switch unit is dust and water resistant to an IP67 rating, helping protect its electronics when installed in areas exposed to dirt, dust and moisture.Multiple Temperature Sensor Options: You can choose a probe sensor or a probe with a thermatic coolant temperature sensor, allowing you to select a sensing arrangement to suit your installation.Flexible Probe Installation: You can install the probe directly into the cooling system through the top radiator hose or position it between the radiator fins, giving you practical installation options for different cooling system layouts.Thermatic Sensor Installation: The optional thermatic coolant temperature sensor can screw into an engine or radiator waterway, or you can install it into a coolant hose using a separately available adaptor for direct coolant temperature measurement.12V Operation: You can use the switch with 12V systems as supplied or for 24V systems the relays need to be replaced with 2x suitable 24V relays (part number 10534).The Gen II Digital Thermatic EWP / Fan Switch helps you automate fan or electric water pump operation according to the coolant temperatures you set. Its adjustable switching range, independent relay outputs and sensor options give you a practical way to configure temperature-based cooling control around your installation. It makes a useful addition to your cooling system when you want automatic switching with the option of manual control when required.Please note: When used with an electric water pump, the switch only turns the pump on and off and does not control pump speed. For pump speed control, a Davies Craig EWP / Digital Fan Controller is required.Kit contents - Gen II Switch Unit, Ring Terminals, Self Tapping Screws, Wiring Connector, probe sensor mounting kit, probe sensor or probe and thermatic sensors.Dimensions - 95 x 65 x 56mm
