eTRV
Thank you for buying the MiHome eTRV (electronic Thermostatic
Radiator Valve). Please read through this manual before using the
product, and follow the instructions.
This eTRV can be installed as part of the MiHome smart home
network.
The eTRV can only be fitted to a radiator that
already has a thermostatic radiator valve, as
shown opposite. It has been designed to fit most
standard radiators. In this case, the eTRV is easy
to fit and there is no plumbing work involved.
If you have a manual radiator valve, as shown
opposite, you will need to have a normal
thermostatic radiator valve fitted first. You may
need professional help from a heating engineer
or registered plumber.

What is a thermostatic radiator valve (TRV)
TRVs sense the temperature of the air around them and regulate
the flow of water through the radiator accordingly. They do not
control the boiler.
TRVs 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
and the size and type of radiator. 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, your boiler will need to be controlled by a thermostat in a
room. The radiator which is in the room that the boiler thermostat
is in should not normally have a TRV. If it does, keep the TRV on the
maximum setting and adjust the boiler’s thermostat as explained
in the instructions for your boiler.
This manual explains how to install, use and maintain the eTRV.
Please keep this manual in a safe place so you can refer to it in the
future if you need to. If you need this guide in large print, download
the instructions from www.MiHome4u.co.uk.

Using Your eTRV
Each eTRV controls a radiator valve to regulate the heating in the
room. This is based on timed programmes and set temperatures
under control of the MiHome network. Using the eTRV improves
your comfort and saves energy.
The MiHome eTRV is controlled remotely via radio which has a
range of 25 metres approximately in open air.

Contents
The box should contain the following items and accessories.
You will need:
•a Phillips screwdriver
You may need:
•an adjustable spanner (to remove the existing TRV)
6
The eTRV is compatible with valves made by:
•Barlo
•Myson
•Braukmann
•Pegler
•Drayton
•Regis (B&Q)
•Honeywell
•Siemens
•Landis & Gyr DuoGyr
and many others.
Installation
The first step is to remove your existing TRV head.
Step 1 - Turn the TRV thermostat anticlockwise as far as it will go.
Step 2 - Release the base by turning it anticlockwise, by hand or
with a spanner.
Step 3 - Pull the existing TRV thermostat off the valve.

Inserting the Batteries
Step 1 - Using a Phillips screwdriver
(one with a cross tip), unscrew the
screw at the top of the battery-
compartment, but do not remove the
screw.
Step 2 - Remove the battery
compartment cover, with the screw
still in it.
Step 3 - Insert the two AA (LR6)
batteries that came with the eTRV into
the battery compartment as shown.
Make sure you put the batteries the
right way round. Inside the battery
cover there is a diagram showing which
way to fit the batteries when looking
from the front of the eTRV.
Step 4 - Put the battery compartment cover back on. Hold it in
place while you gently tighten the screw. Overtightening may crack
the screw seating.
After 5 seconds the motor will start up to exercise the valve stem.
You may need to wait several minutes for this process to complete.
You will see the LED lamp on the unit flashing red as this motor is
driven. You will then see the green led flash 3 times when the stem
is finally full retracted. The LED lamp should then flash orange
slowly indicating it is ready to install on the radiator.
Important - The batteries provided with the eTRV will last for up to
1½ years, depending on how often the motor runs. When you need
8
to replace the batteries, insert new high-quality AA alkaline
batteries. Do not use rechargeable batteries.
Choosing and fitting a base ring
The base-rings and spacers allow your eTRV to fit to either 28mm
or 30mm radiator valves, whichever is already on your radiator. The
28mm ring has notches inside it.
It is important that you use the correct size base ring for your valve.
To check which one to use, remove the existing TRV as shown
earlier.
9
To identify which base ring to use, take
one and screw it onto the radiator valve,
before attaching to the eTRV, to see if it
fits.
When you have found the correct base-
ring, unscrew it so you can attach it to the
eTRV.
Important - Test which base ring fits each radiator valve before
attaching it to the eTRV.
Choosing and fitting a spacer
In most cases (where
the valve pin is taller
than 14mm), you will
need to fit a spacer
inside the base ring.
The spacer comes in
two thicknesses, 2mm
and 3.5mm. It is
important that you
use the correct size
spacer.
Tip –the 3.5mm-thick
spacer is the same
thickness as a £1 coin
10
If you need to use a
spacer, put it in place in
the base ring before you
attach the base-ring to
the eTRV.
Once the spacer is in
place, attach the base-
ring to the eTRV.
Step 1 - Put the correct
spacer (if one is needed)
in the base ring.
Step 2 - Fit the base ring
onto the eTRV.
Step 3 - Firmly push the
three base-ring pegs into
the slots on the base ring.
