The SST Soft Start Timer is a fully weatherproof solution for controlling up to 4kW of electric heaters (such as infrared quartz halogen). It provides timed heat on demand delivering energy savings of up to 30%* by switching off automatically when unattended. The timer will also prolong the life of the heating elements through soft-start and soft-stop technology, thus reducing maintenance costs.

The SST4-PB is operated using an integral pushbutton, which features an LED indicator to ensure the button is easily located in the dark.  When triggered, power is gradually applied to the heater over 3 seconds so avoiding large inrush currents and reducing stress to both the heating element and the electrical supply. The heater remains powered for the pre-set time period, set by an internal dial (fully adjustable from 5 to 60 minutes), before being automatically turned off in a similar manner.

The integral LED blinks to notify room users when there is less than 1 minute remaining of the time delay before the heater automatically switches off. The time delay may be reset with a brief press of the pushbutton. The timer can be cancelled at any time with a prolonged button press.

The unit is designed for outdoor installation, rated to IP65 and housed in a robust high-quality polycarbonate enclosure. All connections are made through preinstalled cable glands, and wall mounting is achieved via pre-drilled holes in the enclosure which maintain its ingress protection rating.

The SST4-PB can control a maximum load of 4kW.

This 4kW Soft Start Timer is ideally suited to a number of applications, including retrofitting to existing equipment to achieve significant savings on energy usage and lamp replacement costs.

• Pub and beer gardens
• Restaurants and Hotels
• Patio and gardens
• Smoking shelters
