Page 23: Control Systems
Control Systems Ambient Sensing The ambient sensing control systems activate the heating cable when the ambient temperature falls below the thermostat set point. It is important that these devices are installed above ground at the pipe segment that is subject to the lowest tempera- tures and fastest wind speeds. - Page 24 Line Sensing The line sensing control systems activate the heating cable when the pipe temperature drops below the desired setpoint. The sensor must be secured to the pipe with aluminum tape and the insulation must be sealed where the capillary comes through. The device should be mounted above ground in an area without heavy pedestrian or equipment traffic.
