1. Advice regarding thermostats and regulators Electrical floor heating gives a very comfortable and economical heat Floor heating is somewhat slower to regulate than wall mounted heating and the best results are achieved when using an electronic thermostat for temperature control In wet rooms it is common to use a thermostat with a floor sensor only Comfortable bare foot temperature is usually around 26 C 79 F User manual The heating cable system should not be turned on before the floor has hardened naturally The thermostat or control system must be used according to the manufacturer s instructions Avoid drilling cutting attaching bolts or similar in the heated floor If this must be done contact an electrician who can help locate heating cables Documentation of the heating system received from the installer should provide information on where the cables are located In rooms with an area power of 100 W m or more for example in a bathroom carpets are not to be used Caution is to be taken when placing insulating items on the floor such as diaper packages heaps of clothes and so on Such items should preferably be placed in other areas In rooms with an area power of 100W m or less pay attention when placing insulating items on the floor for example carpets or furniture without feet Permanent installations covering a room area should always be installed in non heated areas The heating cable is tested in conformity with IEC 608002.
