Getting the most from your evohome system

Thanks for choosing an evohome Wireless Radiator
Zoning Kit. By adding Wireless Radiator Zoning Kits
to your evohome system you are creating smart
zones which means more comfort, more control
and savings of up to 40% on heating your home*.
Energy savings by smart zoning
Heating the whole house as one zone is like
turning all your lights on from one switch. With
an evohome Connected Pack and a Wireless
Radiator Zoning Kit on each radiator you can
divide your home into separate areas based on
your lifestyle, so you only need to heat areas
depending on when and where you spend time.
Working with zones
A zone can be one room or a number of rooms. For
example you may want to group all of your bedrooms
as one zone and control them together. Alternatively,
if you have several radiators in a single room or
open space, they can be grouped into a single zone
so you don’t need to control them individually.
Getting the most from your evohome system
*Source: Energy Saving Research Unit (ESRU), Strathclyde University 2013 & TACMA 2013 - Energy savings quoted were calculated
using a 3 bedroom, 2 level home, located in the UK, modelling a family of 4 over a typical week’s activity, comparing an evohome smart
zoning system, with recommended settings, to a system comprising of a simple timer, single non-programmable room thermostat and
no Thermostatic radiator valves. Individual Energy savings gained are dependent upon existing controls, environment and lifestyle.

Set up your Radiator
Controller
If you are adding one or more Wireless Zoning Radiator
Kits to an evohome Connected Pack you need to power
up the Radiator Controllers and then bind them to the
evohome Controller using the ‘Installation Menu’.
It may be easier to power up and bind the
Radiator Controllers while they are close to
the evohome Controller – you can install
them in their assigned zones later.
When you bind a Radiator Controller to the
evohome Controller it permanently stores the
connection and there should never be a need
to rebind them even after a power cut.

12 Set up your Radiator Controller

Using your Radiator
Controller
The Radiator Controller will operate your smart
zone according to the programmed settings from
the evohome Controller and you shouldn’t need
to make many adjustments at the radiator.
There are however some basic adjustments and display
information you can do on the Radiator Controller.

Replacing the batteries 15
Automatic monitoring functions 16
Emergency operation 17
13Installation & User Guide

Manually override a room’s
scheduled temperature
The sheduled temperature for the room can
be changed by turning the adjustment dial.
This remains active until the Radiator Controller
receives the next scheduled temperature
change from the evohome Controller.
The symbol on the display shows
that the temperature was changed
manually and remains until the next
scheduled temperature change.
Turn the radiator OFF
By turning the adjustment dial
anticlockwise until OFF is displayed, the
valve will be closed permanently.
With the Radiator Controller set to OFF
it will no longer follow the programed
schedule from the evohome Controller.
It will still operate according to the frost
protection setting and will still run its valve
cycle to prevent the valve seizing.
To resume the heating schedule you need to
set a temperature on the Radiator Controller.
When the next set temperature is received from
the evohome Controller the Radiator Controller
will then follow the programmed schedule.

Window open function
In order to save energy, if a window or
door gets opened and causes a sudden
temperature drop in the room, the Radiator
Controller closes the radiator valve.
window is displayed on the Radiator Controller
and the symbol is displayed on the
evohome Controller for that room.
When the temperature begins to rise again
the Radiator Controller will reopen the
radiator valve after 30 minutes (default).
Valve protection
To prevent the radiator valve from seizing, if
the valve has not been fully opened within a
period of two weeks the Radiator Controller
will cycle the valve open and closed. This
will happen on the Monday after the two
week period has been detected.
cycl is displayed on the Radiator
Controller during the valve cycle.
Frost protection
To prevent the water in the heating pipes from
freezing, if the room temperature drops below 5°C
the Radiator Controller opens the radiator valve
and closes it again when the temperature rises
to 6°C. It will maintain this cycle until the room
temperature rises above the frost protect level.
frost is displayed on the Radiator Controller
during the frost protection period.
Automatic monitoring functions
The heating system
must be switched
on for the frost
protection function
to operate.
