Warmup 3iE WU-3IE-CC Programmable Thermostat Installation Guide

Warmup 3iE WU-3IE-CC Programmable Thermostat

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 the thermostat
2. Floor sensor installed in the floor to be heated (see Warmup heater instructions for details)
3. Optional 2nd sensor (either installed in the floor or outside the house)

The thermostat is not a safety device and should only be used with Warmup heating products. In order to avoid damaging your flooring the correct floor type should be selected during the thermostat programming process. Electrical Specification:

• Supply voltage: 230V +/-15% at 50Hz
• The thermostat is not designed for use with an intermittent power supply.
• Maximum Switch Load: 16A resistive
• 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 the latest IEE Wiring Regulations and appropriate Statutory Regulations.

Location of Thermostat

The thermostat should be installed inside a standard 55mm wall socket 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 a relative humidity of 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. A conduit has been provided with this 3IE thermostat. The use of this conduit will protect the sensor and will allow easier repair of the sensor in the case of sensor damage after the flooring has been laid. When installing the floor sensor, it is recommended to use
the following process:

1. Work out the desired locations of the thermostat and floor sensor. Measure the distance of the conduit required and cut the conduit to the correct length. The end of the conduit should be located somewhere easily accessible even after all flooring material has been fixed. It is recommended to minimize the length of the conduit and avoid sharp corners.
2. Straighten both sensor cable and conduit. Push the sensor all the way through the conduit and ensure the sensor protrudes from the protective conduit by 3-4 cm.
3. Place a metal cap over the sensor and then push back ensuring a firm fit between the conduit and the metal cap Warning: Do not attempt to cut the conduit with a sensor installed. This could lead to irreparable damage to your sensor.

Installation

Separate the front housing of the thermostat from the wall module:

1. Un-screw both closing screws (bottom of stat) until they will not turn any further.
2. Release the front housing by gripping the lower half of the outer frame and pulling outwards then upwards
3. Place front housing somewhere safe
4. Run all wires to the wall box. Check to ensure that you have included the following:
   • Power (Live and Neutral)
   • Heater (Live and Neutral)
   • Floor sensor
   • Fil pilote (if necessary)
   • External/2nd-floor Sensor (if necessary)

Pull wires through the wall box and complete terminal wiring.
IMPORTANT: Ensure that multi-strand wires are fully inserted into the terminal and secured tightly. Any loose strands should be trimmed as they could cause a short circuit.

Normal electrical installation (see numbers on the diagram to right)

• Connect to Power Supply (Live – MAX 240V)
• connect to Power Supply (Neutral – MAX 240V)
• Connect to Warmup heater(s) (Neutral – MAX 3600W/ 16 Amps)
• Connect to Warmup heater(s) (Live – MAX 3600W/ 16 Amps)
• Connect to 1st wire of the floor sensor (the color is not important)
• Connect to 2nd wire of the floor sensor (the color is not important)

Special installations
(should only be performed under the supervision of Warmup)
Fil Pilote installation: (only for use in France)

1. Connect to fil pilot (F.P.)
2. Second sensor installation: (2nd-floor probe or exterior probe)
3. Connect to 1st wire of external sensor/2nd-floor sensor
4. Connect to 2nd wire of external sensor/2nd-floor sensor Master/Relay installtion: (connecting 2 stats together)
5. Connect to terminal 6 on another thermostat
6. Connect to terminal 7 on another thermostat

Mounting thermostat into the wall box

1. Push excess wire back through the wall box and insert the thermostat back module into the wall box.
2. Put fixing screws through mounting holes and tighten.
3. Ensure that the thermostat is straight before tightening completely.
4. Replace the thermostat front housing align and sit the front housing on to hinges, push the lower half of the front housing until a ‘click’ is heard.
5. Ensure front housing is securely fixed.
6. IMPORTANT: Tighten both retaining screws

Powering-up
You can now power up the thermostat and begin the programming process. An easy-to-follow menu will guide you through the rest. If you want to turn on / off the thermostat and heating system then hold down the recessed button on the bottom of the stat for 3 seconds When you have ensured that both the floor sensor and heating elements are working correctly you can complete the installation of floor covering and removing the protective cover on the front of the thermostat.

Error Messages
Your thermostat can give you four error indications:

1. heater error”: This will occur if the heater is not correctly connected to the thermostat
2. “overload”: This will occur if more than 3.6kW (16 Amps) has been connected to the thermostat
3. “er1”: This will occur if no floor sensor is detected
4. “er2”: This will occur if the floor sensor has a short circuit
