IMPORTANT SAFETY NOTE
This product uses mains voltage electricity and work should only be carried out by a qualified electrician. You should always isolate the power
supply before attempting to install or repair the 3IE thermostat. The thermostat should not be put into operation unless you are certain that the
entire heating installation complies with current general safety requirements for electrical installations. Electrical installation to be in
accordance with latest IEE Wiring Regulations and appropriate Statutory Regulations.
Location of Thermostat:
The thermostat should be installed inside a single gang electrical wall box that is at least 30mm deep. For optimal performance the thermostat
should be located in an area with good ventilation. It should not be beside a drafty window/ door, in direct sun-light or above another heat
generating device (e.g. radiator or TV).
The thermostat is designed for operation between 0°C and 55°C with relative humidity less than 80%.
Location and installation of floor sensor:
The optimum location of the floor sensor is described in each ProWarm
sensor location.
The floor sensor provided with the 3IE thermostat enables accurate temperature control of the floor heating system. When the thermostat is being
used to control floor heating under a wooden floor or other delicate floor coverings such as carpet or vinyl the floor sensor MUST be installed.
The floor sensor must be at least 300mm from the wall and should be placed centre of two heating element runs. When positioning the floor
sensor avoid placing the sensor in areas where it may be exposed to sunlight or draughts. Avoid areas where there are hot water pipes that may
affect the temperature reading.
As the warranty does not cover the floor, it is recommended that the floor sensor is installed into a non-conductive conduit. This will allow for
easy replacement of sensor after the flooring has been laid.
Make sure the conduit has a gradual bend when it enters floor, this will ensure the sensor cable can be easily inserted or withdrawn. Seal the end
with tape to prevent adhesive/screed from entering the conduit.
Route the conduit to the connection box. The end of the conduit should be easily accessible after the flooring has been fixed.
Warning: Do not attempt to cut conduit with sensor installed. This could lead to irreparable damage to your sensor.
