What does it do?
The terrier i-temp is a programmable radiator control
(PRC) that gives you time and temperature control of
each individual radiator and is designed as an upgrade
to existing thermostatic radiator valves. Heating the
whole house when you don’t need to increases your
carbon footprint and can also cost you hundreds of
pounds on wasted fuel every year – money that you
could save with the terrier i-temp.
So – you only heat rooms at times when you need to!

How does it work?
The terrier i-temp is a simple add-on to
your heating system – you don’t need to
change the way your master programmer
works as this will continue to control the
overall heating times for the whole house.
As such, terrier i-temp brings an extra
element of control, allowing you to fine-
tune your heating room-by-room.

The radiator thermostat can be operated
in three different modes:
Manual mode (Manu)
The set-point temperature can be changed
with the thumb wheel. The terrier i-temp holds
the set temperature.
Automatic mode (Auto)
The temperature will be controlled automatically in
accordance to the stored weekly program. In
automatic mode the temperature can be modified at
any time using the thumb wheel. terrier i-temp will
return back to stored program at the next switching
time.
Holiday mode/Timed override
The terrier i-temp can be set to maintain a specific
temperature. This temperature will be maintained up
to a user defined date and time.
Operating modes
The programming will define temperatures for a time
range from 0:00 until 23:59. You can decide if you want

Sofa programming
As a feature, you can programme the terrier i-temp
before the installation or removed from the valve.
HOW?
After inputting the date time and programme, “Ins”
will appear, wait until the “O” stops, then follow
the installation process.
Increasing your temperature 
or reducing the temperature 
The terrier i-temp uses the concept of a comfort and
set-back temperature. These temperatures are pre-
defined as a factory default but you have the
flexibility to change these two temperature points to
suit your needs.
HOW?
By pressing once or twice the temperature
will alternate and switch between these two higher
(comfort) and lower (set-back) temperature points.
To set your own comfort and set-back temperature
simply hold for 3 seconds, select a comfort
temp, press “OK”, then select your set-back temp
and press “OK”.
Simple optional settings Child-proof lock
A key combination activates a key lock.
HOW?
Select “MENU” and together. The same
combination deactivates the key lock.
Manual temperature adjustment
When you want to operate the terrier i-temp in
manual function without using the time element.
HOW?
Press “MENU” to enter manual mode, then rotate
the thumb wheel to your desired temperature.
Holiday/Timed override
If you want a fixed temperature to be maintained for
a set period of time, for example while you are on
holiday or during a party, make use of the
Holiday/Timed Override function. The set temperature
will remain in force until the user specified time.
After which, the terrier i-temp will adopt Auto mode.
HOW?
Press and release the “MENU” button twice until the
suitcase symbol ( ) appears on the display. Use
the thumb wheel to set the end of the time period.
Press “OK” to confirm. Use the thumb wheel to set

20 21

Simple optional settings
press “OK” to confirm. The display will flash to
confirm your settings.
Heating break (summer)
In the summer-time, most heating systems are turned
off. During this time, the valve can be opened
completely to reduce battery consumption.
HOW?
Select “MENU” to activate manual mode, turn thumb
wheel clockwise until “ON” appears. To revert back
select “MENU” and switch back to auto or turn the
thumb wheel anticlockwise.
Valve closing
The valve can also be completely closed, however the
frost protection remains active.
HOW?
Select “MENU” to activate manual mode. Turn thumb
wheel anticlockwise until “OFF” appears. To revert
back, select menu and switch back to auto or turn
the thumb wheel anticlockwise.
Automatic time adjustment ( )
The terrier i-temp will automatically adjust itself
when time settings change between British Summer
Time and Greenwich Mean Time.
Automatic open window detection ( )
terrier i-temp recognises a sudden fall in
temperature, as caused by a window being opened,
and saves energy by automatically reducing the
temperature for 15 minutes. The window-symbol
displays while this ‘ventilation function’ is activated.
Automatic frost protection
If the room temperature drops below 5°C, terrier
i-temp switches the radiator on at a 5°C temperature
(assuming the heating system is on). This feature
prevents pipes or radiators freezing in extreme cold
and prevents condensation forming.
Automatic self check
(decalcification) ( )
An automatic self test takes place once a week. This
ensures that the connections are aligned. This feature
cannot be deactivated.
Automatic settings have the ability to be modified.

Temperature compensation offset
(toF)
terrier i-temp measures the temperature at the
location of the radiator, but other parts of the room
may be warmer or colder. To compensate for this, you
can set a temperature offset of ±3.5°C. If, for example,
terrier i-temp is set to 20°C and a temperature of
18°C is measured elsewhere in the room, an offset of
-2.0°C should be configured.
HOW?
Press and hold down “MENU” for more than
3 seconds. Use the thumb wheel to select the “tOF”
menu item. Confirm with “OK”. Use the thumb wheel to
modify the temperature (offset). Press “OK” to confirm.
Temperature limitation (tLi)
This is used in situations where you may want to limit
the maximum temperature that can be set for a
particular room.
HOW?
1 Hold “MENU” for 3 seconds until “Pro” appears
2 Use thumb wheel to scroll to “reS”
3 Hold “MENU” and at the same time
4 “tLI” will appear, adjust maximum temperature
to your choice.
Restore factory settings
You can reset the actuator to its initial state
manually. This will clear all the settings that
have been made manually.
HOW?
Press and hold down “MENU” for more than 3
seconds. Use the setting thumb wheel to select
the “reS” menu item. “ACC” will appear.
Confirm with “OK”.

Radio functionality – learning device
terrier i-temp is ‘future-ready’ with the ability to
integrate with accessories such as window sensors
or remote controls, and can be programmed from a
home computer to four such components using the
teaching-in function.
HOW?
The teaching in function can be activated by pressing
“OK” for 3 seconds. The display then shows a
countdown of 30 seconds; during this time terrier
i-temp ‘listens’ for new devices. If a device such as a
remote control emits a signal with the specific
protocol during this time, terrier i-temp will have
“taught-in” this remote control and will accept
commands from it.

Installation – using adaptors
1Remove the valve head by
unscrewing the fixing ring.
2Select the appropriate
adaptor for the
thermostatic valve and
attach to the valve body.
Note: you will need to
open the adaptor with a
screwdriver for it to fit
fully onto the body
3Use the small bolt and
nut to secure the adaptor
to the body.
4Place the i-temp head
onto the valve body.
5Turn the fixing screw by
hand until tight. Note: Do
not use grips or other
tools which may damage
the fixing ring.
An example of installation
using adaptor AD1.
36 37

Valve installation
We recommend that a competent installer is used
to install valve bodies.
Fitting
1. Thoroughly clean any pipe work to be connected
to the valve
2. Drain down existing system, connecting a
hosepipe to the lowest drain off point available
3. Screw 1
/
2" BSP tail into radiator tapping, using
suitable jointing material, e.g. PTFE tape
4. Connect valve body to tail and tighten nut
5. Cut and fit copper tube to valve body –
tightening nut and cone
6. Remove manual shut off cap and store safely
PLEASE NOTE:
To avoid the problem of hydronic (water flow) noise,
it is recommended that the differential pressure
valve should be fitted to any system with TRVs
(Pegler order code for differential pressure valve
678021/22mm) will be suitable for most domestic
installations. Larger sizes are available if required.
What is a thermostatic radiator
valve (TRV)?
TRVs sense the air temperature around them and
regulate the flow of water through the radiator which
they are fitted to. They do not control the boiler.
They should be set at a level that gives you the room
temperature you want. These settings may have to
be different in each room, and you should set the
TRVs to suit each room and then leave them to do
their job.
Turning a TRV to a higher setting will not make the
room heat up any faster. How quickly the room heats
up depends on the boiler size and setting, and
radiator size. Turning a TRV to a lower setting will
result in the room being controlled at a lower
temperature, and saves energy.
TRVs need a free flow of air to sense the temperature,
so they must not be covered by curtains or blocked
by furniture.
TRVs cannot turn off the boiler when the whole house
is warm. To do that, you will need a room thermostat
as well. The radiator in the room with the room
thermostat should not normally have a TRV, but,
if it does, keep the TRV on the maximum setting
and adjust the room thermostat as explained with
the instructions.
