to the appliance. The device should be mounted in an
open area, no closer than 30cm from metal objects,
including wall boxes.
Mount the Digistat+RF on a wall which is not subject to
direct sunlight or draughts, preferably on an inside wall,
1.5 metres above the oor. The Digistat+RF must also not
be directly inuenced by radiators or other appliances
giving off heat.
Mounting the Digistat +RF room thermostat
1. Loosen the single screw from the bottom of the
transmitter using a small at bladed screwdriver.
2. Carefully insert the screwdriver into the slot
located at the back of the digistat near the top and
very gently lever upwards a fraction to release
the tab securing the front of the transmitter to the
back cover. The back cover can now be secured to
the wall.
3. Replace the front by locating in position and
pushing fully onto the back cover until the tab
engages at the top of the transmitter.
4. Retighten the screw at the bottom of the unit to
fully secure the front to the back cover.
To cancel signal strength mode:
1. Remove the batteries from the Digistat+RF
transmitter to cancel the constant transmission.
2. After a few seconds the receiver display will show
‘---’ .
3. Press ‘OK’ on the LP20RF receiver and the display
will return to the time with the ‘CH and Antenna’
ashing.
4. Re-insert the batteries into the transmitter and the
RF link will be re-established.

User Guide Digistat+RF Room Thermostat
What is a room thermostat?
A room thermostat simply switches the heating system
on and off 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 off 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 affect 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 off.
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, at 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 may waste energy.
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 different 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 flow of air to sense the
temperature, so they must not be covered by curtains or
blocked by furniture. Nearby fires, televisions, wall or table
lamps may prevent the thermostat from working properly.

User Guide LP20RF Programmer & Receiver
If the engineer has set your program and timings – you do
not need to do anything else. Just keep this guide in a safe
place for future reference.
Introduction
The programmer will automatically switch your central
heating and hot water on and off at times that suit you.
The green light on the front of the programmer shows
when each one is on. LP20RF has a 7-day program
allowing for different timings on each day of the
week, with central heating and hot water working
independently for up to 3 heating periods each day.
If the engineer hasn’t set your timings for you, your
programmer will work with a standard program that has
been set at the factory. If this doesn’t suit you, it’s very
easy to change it.
Normal Operation
During normal operation the receiver will flash the red
LED, approximately every five minutes. This indicates that a
radio signal is being received from the Digistat transmitter.
Radio Signal Loss
If the red LED does not ash approximately every ve
minutes then the receiver will show a ashing green
LED together with the ashing antenna symbol and the
Central Heating indicator arrow will point to OFF. This
situation indicates that the radio signal link from the
Digistat transmitter has been lost. This may be remedied
by tting new batteries in the Digistat transmitter. If
tting new batteries does not restore the link, then
temporarily move the Digistat transmitter close to the
appliance, if this does not restore the link, then technical
