3iE Installation Guide V4 © Warmup plc - 2013
Introduction:
The 3IE thermostat is designed to aid in the comfort of your home by providing timed regulation of your Warmup
underfloor heating system. The thermostat is designed to receive temperature input signals from the following
sensors:
1. Air sensor located inside thermostat
2. Floor sensor installed in floor to be heated (see Warmup heater instructions for details)
3. Optional 2nd sensor (either installed in floor or outside house)
The thermostat is not a safety device and should only be used with Warmup heating products. In order to avoid dam-
aging your flooring the correct floor type should be selected during the thermostat programming process.
Electrical Specification:
• Supply voltage: 230V +/-15% at 50Hz
• Thermostat is not designed for use with intermittent power supply.
• Maximum Switch Load: 16A resistive
• Insulation Class : II
• Housing : IP20 (IP32 when used with gasket- see fitting instructions)
• Standards: EN60730-1 & EN60730-2-9 standards
WARNING – 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 Warmup heater installation manual. Refer to that manual
when selecting floor 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.
