NB: In order to ensure proper operaon of the product, ensure that the thermostat is
not posioned near to an area which could be aected by
interference from another source. E.g.: a wireless transmier 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 dierences that may exist
between dierent locaons in the house if the temperature is not uniform.

Display disappears on programmer:
- Check fused spur supply.
Heang 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 pro-
gramme then try BOOST as this should ope-
rate in any posion.
- 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 ed 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 posion.
- 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 ed has
opened.
The boiler is not heang:
- 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 o. If no increase set temperature.
- Check the posion of the baeries. Remove
them for 30 seconds and reinsert them. If the
problem persists, replace the 2 baeries.
Nothing in the display:
- Check the posion of the baeries. Remove
them for 30 seconds and reinsert them. If the
problem persists, replace the 2 baeries.
The room temperature is not high enough, the
boiler is not providing enough heat:
- Check the acve desired temperature and in-
crease it if need be (see page 3).
You made a mistake while seng:
- You just need to restore factory sengs, as ex
-
plained in the “Factory sengs” secon (see
page 4). This will reverse any changes you mi
-
ght have made.
The system is not heang 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.
...an Explanaon for Householders. Program
-
mers allow you to set ‘On’ and ‘O’ me pe-
riods. Some models switch the central heang
and domesc hot water on and o at the same
me, while others allow the domesc hot water
and heang to come on and go o at dierent
mes. Set the ‘On’ and ‘O’ me periods to suit
your own lifestyle. On some programmers you
must also set whether you want the heang
and hot water to run connuously, run under
the chosen ‘On’ and ‘O’ heang periods, or be
permanently o. The me on the programmer
must be correct. Some types have to be adjusted
in spring and autumn at the changes between
Greenwich Mean Time and Brish Summer
Time. You may be able to temporarily adjust the
heang programme, for example, ‘Advance’, or
‘Boost’. These are explained in the manufactu
-
rer’s instrucons. The heang will not work if
the room thermostat has switched the heang
o. And, if you have a hot-water cylinder, the
water heang will not work if the cylinder ther
-
mostat detects that the hot water has reached
the correct temperature.
