Index3 Installation Instructions Important note RF products: Ensure that there are no large metal objects, such as boiler cases or other large appliances, in line of sight between the transmitter and receiver as these will prevent communication between thermostat and receiver. Product Speci cation Please Note: This product should only be installed by a quali ed electrician or competent heating installer and should be in accordance with the current edition of the IEEE wiring regulations. Thermostat features RT51/52 RT51/52-RF Power supply 2 x AA/MN1500/LR alkaline cells Memory back-up 1 min. for battery change Switching action of output relay 1 x SPDT, Type 1B N/A Switch rating of relay contact 3(1)A, 10-230Vac N/A Transmission frequency (RF model) N/A 433.92MHz Transmitter range (RF model) N/A 30m max Temperature range 5-30°C Dimensions, mm 110 wide, 88 high, 28 deep Design standard EN60730-2-9 (EN300220 for RF) Rated impulse voltage 2.5Kv Ball hardness test 75°C Control pollution situation Degree 2 Temperature accuracy ±1°C Installation Instructions GB4 Installation First, remove the wallplate from the back of the unit. From the top left hand corner of the wallplate, there must be clearances of at least 140mm to the right, 15mm to the left, 30mm above and 100mm below in order to mount the plug- in module. Installation Instructions GB5 Prior to mounting the unit should be set in either ON/OFF or chrono-proportional control mode (see below). ON/OFF - boilers switches ON when below set temperature and OFF when above. Chrono-Proportional - energy saving feature which res the boiler at regular intervals to maintain a set temperature, achieving a constant ambient environment for the user. Some existing thermostats will have a Neutral wire and/or Earth wire connected. These are not required by the RT51/52 and must NOT be connected to any RT51/52 terminals. Instead they should be made electrically safe and coiled in the recess at the back of the RT51/52.

RX Receiver Wiring (RF models only) N L NB. For mains voltage operated systems link terminal 2 to mains live supply. Installation Instructions GB7 Commissioning (RF models only) If the thermostat and the receiver have been supplied together in a combined pack, the units have been paired in the factory and no commissioning is required (RX1 only). To tune the RX receiver to the frequency of the thermostat signal, follow steps 1-5 below. Step 1 RT51/52-RF Reset the unit by removing the batteries for 2 minutes, then replace. Step 2 Press and hold V and + buttons for 3 seconds (Thermostat now transmits unique signal continuously for 5 minutes). Step 3 RX1 Press and hold buttons PROG and CH1 for 3 seconds until green light ashes once. Step 4 RX2 (if applicable) Stat 1 - perform steps 1-3. Stat 2 - wait 5 mins, perform steps 1-2 and then press PROG and CH2 on RX2. RX3 (if applicable) Stat 1 - perform steps 1-3. Stat 2 - wait 5 mins, perform steps 1-2 and then press PROG and CH2 on RX3. Stat 3 - wait 5 mins, perform steps 1-2 and then press PROG and CH3 on RX3. Step 5 RT51/52-RF Press Λ or V to select temperature - unit will revert back to operating mode.

What is a programmable room thermostat? ... an explanation for householders A room thermostat simply switches the heating system on and o as necessary. It works by sensing the air temperature, switching on the heating when the air temperature falls below the thermostat setting, and switching it o once this set temperature has been reached. Turning a room thermostat to a higher setting will not make the room heat up any faster. How quickly the room heats up depends on the design of the heating system, for example, the size of boiler and radiators. Neither does the setting a ect how quickly the room cools down. Turning a room thermostat to a lower setting will result in the room being controlled at a lower temperature, and saves energy. The heating system will not work if a time switch or programmer has switched it o . The way to set and use your room thermostat is to nd the lowest temperature setting that you are comfortable with, and then leave it alone to do its job. The best way to do this is to set the room thermostat to a low temperature – say 18°C – and then turn it up by one degree each day until you are comfortable with the temperature. You won’t have to adjust the thermostat further. Any adjustment above this setting will waste energy and cost yo u more money. If your heating system is a boiler with radiators, there will usually be only one room thermostat to control the whole house. But you can have di erent temperatures in individual rooms by installing thermostatic radiator valves (TRVs) on individual radiators. If you don’t have TRVs, you should choose a temperature that is reasonable for the whole house. If you do have TRVs, you can choose a slightly higher setting to make sure that even the coldest room is comfortable, then prevent any overheating in other rooms by adjusting the TRVs. Room thermostats need a free ow of air to sense the temperature, so they must not be covered by curtains or blocked by furniture. Nearby electric res, televisions, wall or table lamps may prevent the thermostat from working properly.9 Your room thermostat RT51 The RT51 is a simple to use room thermostat which allows you to programme a Day and a Night temperature, and to switch between the two settings simply by pressing 2 buttons. RT52 The RT52 has the same functionality as the RT51 with the added bene t of a built-in timer, which will return the thermostat to Day temperature at a time chosen by you. Wireless RF versionsBoth models are available in wireless versions - RT51-RF and RT52-RF - which o er exactly the same functions as the hard-wired models. Each thermostat communicates with an RX receiver, which can be located up to 30m away. Reading your display User Instructions

DAY modeNIGHT modeActual room temperature Required room temperature Room temperature is lower than required temperature, therefore thermostat has switched on and is calling for heat User Instructions GB10 Before you start To reset the unit, open the ap on the front of the programmer. Remove the batteries for 2 minutes, then replace.The display will automatically default to DAY mode (d shown top left of display) and show actual temperature in the large characters and required temperature in the smaller characters. DAY temperature Use the and buttons until the required DAY temperature is shown. NIGHT (set-back) temperature Press and buttons together once to select NIGHT mode (n shown top left of display). Use the and buttons until the required NIGHT (set-back) temperature is shown (between 5-30°C or O ). Setting the DAY & NIGHT temperatures

All models User Instructions GB11 Pressing the and buttons together once allows you to toggle between DAY and NIGHT mode as required. Setting the clock Press PROG button once. Use and buttons until the correct TIME is shown. Press PROG button again. Use and buttons to select the time you wish the unit to return to DAY mode. RUN Mode Moving between DAY and NIGHT mode RT52 / RT52-RF only Setting the Return to Day Time i2 00 Press PROG again to return to RUN mode. The unit will now control your heating at the temperatures you have set. User Instructions GB12

All models Battery Replacement When batteries are low a battery symbol will ash in the LCD display. You have 15 days to replace the battery before the unit will switch o . When changing batteries, remove old batteries and insert new ones within ONE MINUTE and programming will not be lost.
