The Envirostat FP4E controller provides energy-efficient protection against damage caused by low temperatures, frost and damp. It can either be used on its own or in parallel with the CC3 4kW controller to provide a combination of automatic 24 hour frost protection and comfort warmth when an area is in use. The FP4E features a soft-start circuit that prolongs the operating life of the heaters and prevents any risk of nuisance tripping at the MCB caused by inrush current. It will bring the heaters on only when it is essential to raise the temperature for frost-protection duties. In addition to working with quartz halogen infrared heating, the FP4E works with trace heating installed to protect pipework. Supplied with a thermistor temperature sensor on a 2m long lead. The control set point is adjustable from -10°C to +10°C.
* also compatible with Infreso P,S & T 4kW controllers.
PRODUCT SETUP
Connect the mains supply and load to the controller using appropriately sized round section cable. Position the sensor to measure the air temperature where required, or use cable ties to fix the sensor to a pipe etc. Set the set-point temperature dial.
