A, Installation & Mounting:1, Installation Location:The thermostat (Transmitter) should be mounted on an inner wall 1.5mabove the floor in a position where it is readily affected by changes in theambient room temperature. Prevent direct exposure sunlight and moisture.Do not place this unit where air circulation is low, or where it is susceptibleto rapid temperature changes (e.g. near a door or window). Do not positionnear heating/cooling appliances.3Caution:Turn off the ET4 and any electrical devices that are to beconnected after installation. The installation must be carriedout by a qualified electrician and conform to current IEEregulations.TFC Group LLP, Tower House,Vale Rise, Tonbridge, Kent TN9 1TBhttp://www.tfc-group.co.ukET4RF ThermostatINSTRUCTION MANUAL1Transmitter Battery Installation / Replacement:Caution: Turn off electrical devices and disconnect the supply to anyconnected appliances before installing or replacing batteries. Replace onlywith the same (AAA Alkaline) or equivalent batteries. Do not dispose of usedbatteries with household waste. Refer to your local area for correct disposalmethod.ET4 Installation1, Pull out the battery draw.2, Place new batteries taking note oforientation of +/- on battery drawer.3, Dispose old batteries properly.4, Slide battery draw into position.5, Check operation and press reset(RST) if not functioning correctly.5(Figure 1)2, Wiring:There are four terminals on the receiver. L , N , 1 & 2.Volt free connection:If connecting to a volt free system 220-240 VAC should be connected toL & N and the switched pair into terminals 1 & 2. If the circuit has a sendand return, the send should be connected to terminal 2 and the return toterminal 1.Mains switching:Connect 220-240 VAC to L & N, Link Live (L) to terminal 2. Terminal 1gives a 230V AC switched live output when heating is in demand.• Refer to the circuit diagram printed on rating label on the back of theproduct.• Push all wiring into wall prior to mounting to avoid trapping wires.The thermostat should be protected by a fuse with a current rating nolarger than 10A.3, Mounting:Mount the ET4 Thermostat using the screw accessories provided throughslots/holes on rear face of the unit. Mount the receiver into back-boxprovided.4ET4 RF Programmable Thermostat1, The system includes one wireless thermostat controller (Tx) plus one RFreceiver (Rx).2, Transmits up to 20 meters indoors.3, Communicates at 433.92MHz(USA/European Standard) and is designedfor unlicensed operation under FCC Part 15.Warning:1, There may be a dead zone in the RF communication. That means thereceiver may not be able to receive the message from the transmitter.Before the installation, check the communication first. If thecommunication fails, relocate the wireless thermostat.2, If there is interference in communication, Follow the set-up procedure tochange the coding between the RF thermostat and receiver.3, It is recommended that the RF thermostat and Receiver are mounted atleast 2 meters from electrical devices such as, radio, TV, PC etc. Do notmount the RF thermostat or receiver on metal wall boxes as this willinterfere with the RF signal and reduce the range.2334466789/10/1111/12121314/1518181920TABLE OF CONTENTSA.

Place 2 newAAA 1.5V alkaline batteries ensuring correct orientation of batterypolarity. LCD display will show.2, Press ‘RST’ to reset. The ET4 is now ready to control the heater/cooler.3, Switch on the heater/cooler. The heater/cooler will remain off until theET4 activates the output, with or displayed depending onconfiguration for a heating or cooling application.C, Normal Time Mode:1, Temperature detection starts and LCD displays the room temperature.2, If the battery is low, will be flashing. If has been flashing for 48hours and the batteries have not been replaced, the ET4 will stopmeasuring the room temperature and the LCD will go blank. The ET4 willturn off the output and the heater/cooler will cease to operate. Thesystem will only function once the discharged batteries are removed andnew batteries are fitted.6 |
