INSTALLING BATTERY

WIRING

All electrical installation work should be carried out by a suitably qualified Electrician or other competent person. If you are not sure how to install this programmer consult either with a qualified electrician or heating Engineer. Do not remove or refit the appliance onto the backplate without the mains supply to the system being isolated.
All wiring must be in accordance with IEE regulations. This product is for fixed wiring only.

Recommended locations for your thermostat.
To ensure that your thermostat provides accurate readings and controls effectively, it must be installed approximately 1.5 m above floor level on an inside wall, away from direct sunshine and any other sources of heat or cold such as radiators, cold draughts, etc.

NB: In order to ensure proper operation of the product, ensure that the thermostat is not positioned near to an area which could be affected by interference from another source. E.g.: a wireless transmitter or receiver, TV, PC, etc.
Important: The thermostat measures the temperature of the place where it is installed. It does not take into account the temperature differences that may exist between different locations in the house if the temperature is not uniform.

PAIRING PROCEDURE

The programmer and the thermostat are not bonded together at the factory.
To bond the programmer and the thermostat together, proceed as below:

Move the 2 mode sliders on both sides of the programmer to the OFF position and then move the program slider to the RUN position. Once this is done, press and hold the RF test button until Pair is shown in the display (approx. 5 seconds). The pairing icon will be flashing.
Within 1 minute, press and hold the RF Test button on the thermostat until PAir is shown in the display (approx. 5 seconds). The pairing Icon will be flashing.
Programmer and Thermostat RF icon will be solid when pairing is complete and normal display is returned.
Note: the programmer is usually located near your boiler. If you want to check the signal strength, press and release the RF test button on the thermostat. RF icon blinks for 10 seconds then signal strength appears. 10 is the best signal strength.

TROUBLESHOOTING

Display disappears on programmer:
• Check fused spur supply.

Heating does not come on:

If the CH Indicator light is on then it is unlikely to be a fault with the programmer.
If CH indicator light is NOT ON then check programme then try BOOST as this should operate in any position.
Check that your room thermostat is calling for heat.
Check that the boiler is on.
Check that your pump is working.
Check that your motorised valve if fitted has opened.

Hot water does not come on:

If the HW Indicator light is on then it is unlikely to be a fault with the programmer.
If HW indicator light is NOT ON then check programme then try BOOST as this should operate in any position.
Check that your Cylinder thermostat is calling for heat.
Check that the boiler is on.
Check that your pump is working.
Check that your motorised valve if fitted has opened.

The boiler is not heating:

Check that the thermostat is calling for heat if yes then the thermostat would appear to be working check that the boiler has not switched itself off. If no increase set temperature.
Check the position of the batteries. Remove them for 30 seconds and reinsert them. If the problem persists, replace the 2 batteries.

Nothing in the display:
• Check the position of the batteries. Remove them for 30 seconds and reinsert them. If the problem persists, replace the 2 batteries.

The room temperature is not high enough, the boiler is not providing enough heat:
• Check the active desired temperature and increase it if need be (see page 3).

You made a mistake while setting:
• You just need to restore factory settings, as explained in the “Factory settings” section (see page 4). This will reverse any changes you might have made.

The system is not heating but is on:
• If and indicator light is on but the system remains cold, then you should contact your installer.

If the problem persists contact your installer.
Note: If Service due soon or service due appears in display please contact your landlord.

TECHNICAL SPECIFICATIONS

Please refer to the installing instructions for any informations about standards and product environment.

NOTE

In some instances the unit may have been set with the service interval function enabled.
By Law in rented accommodation, your gas boiler should be inspected/serviced annually to ensure it is working correctly.
This option is designed to remind the end user to contact the relevant person to have the annual service carried out on the boiler.
This function will be enabled and programmed by your Installer, maintenance Engineer, or Landlord.
If it has been set to do so, the unit will display a message on the screen to remind you that a boiler service is due.
The Service Due Soon countdown will be indicated up to 50 days before the Service is due to allow time to arrange for an engineer to attend, normal functions will continue during this stage. At the end of this service due soon period, the unit will go to Service Due OFF at which point only the 1hour boost will operate on TMR7 and PRG7, if the unit is a thermostat RT1/RT7, it will operate at 20°C during this hour. If PRG7 RF, Thermostat has no function.

WHAT IS A PROGRAMMER ?

…an Explanation for Householders. Programmers allow you to set ‘On’ and ‘Off’ time periods. Some models switch the central heating and domestic hot water on and off at the same time, while others allow the domestic hot water and heating to come on and go off at different times. Set the ‘On’ and ‘Off’ time periods to suit your own lifestyle. On some programmers you must also set whether you want the heating and hot water to run continuously, run under the chosen ‘On’ and ‘Off’ heating periods, or be permanently off. The time on the programmer must be correct. Some types have to be adjusted in spring and autumn at the changes between Greenwich Mean Time and British Summer Time. You may be able to temporarily adjust the heating programme, for example, ‘Advance’, or ‘Boost’. These are explained in the manufacturer’s instructions. The heating will not work if the room thermostat has switched the heating off. And, if you have a hot-water cylinder, the water heating will not work if the cylinder thermostat detects that the hot water has reached the correct temperature.

WHAT IS PID

The PID feature works by using a formula to calculate the difference between the desired temperature setpoint and current ambient temperature, the PID feature then predicts how much power to use to ensure the ambient temperature remains as close to the temperature setpoint as possible by eliminating the impact of environmental temperature changes.
