What is a cylinder thermostat?
... an explanation for householders
A cylinder thermostat switches on and off the heat
supply from the boiler to the hot-water cylinder. It
works by sensing the temperature of the water inside
the cylinder, switching on the water heating when the
temperature falls below the thermostat setting, and
switching it off once this set temperature has been
reached.
Turning a cylinder thermostat to a higher setting will
not make the water heat up any faster. How quickly the
water heats up depends on the design of the heating
system, for example, the size of boiler and the heat
exchanger inside the cylinder.
The water heating will not work if a time switch or
programmer has switched it off. And the cylinder
thermostat will not always switch the boiler off,
because the boiler sometimes needs to heat the
radiators.
Cylinder thermostats are usually fitted between one
quarter and one third of the way up the cylinder. The
cylinder thermostat will have a temperature scale
marked on it, and it should be set at between 60C and
65C, then left to do its job. This temperature is high
enough to kill off harmful bacteria in the water, but
raising the temperature of the stored hot water any
higher will result in wasted energy and increase the
risk of scalding.
If you have a boiler control thermostat, it should
always be set to a higher temperature than that of the
cylinder thermostat. In most boilers, a single boiler
thermostat controls the temperature of water sent
to both the cylinder and radiators, although in some
there are two separate boiler thermostats.

Battery Handling
Batteries, rechargeable or not, should not be disposed
of into ordinary household waste. Instead, they must be
recycled properly to protect the environment and cut down
the waste of precious resources.
Your local waste management authority can supply details
concerning the proper disposal of batteries.
In compliance with the EU Directive 2006/66/EC, the button
cell battery located on the printed circuit board inside the
product, can be removed at the end of the product life, by
professional personnel only.
Step 4: Changing the Batteries
How do I know when to change
the batteries?
When the batteries start to run low a battery icon will
flash in the display to indicate “low bat tery”, during
this time the MiStat will function normally. When
the battery icon alone is shown in the display, the
batteries are completely exhausted and the MiStat will
cease to function (see below). Re-activate by replacing
the batteries.
How to replace the batteries
Remove the battery covers as shown. Replace the batteries with 2 x 1.5V IEC LR6 (AA) Alkaline batteries ensuring
correct orientation. Replace the battery covers pressing fully home.

INSTALLATION Guide Step 3: Signal Strength
The MiStat Cylinder thermostat is prebound to the MiStat
receiver in the factory so they just need to be positioned
in the best place for wireless communication. To help
with this there is a built in Signal strength indicator,
available in the Installer settings menu on the MiStat
thermostat, as shown.
It is recommended that the signal strength is Good
or Very Good to ensure ongoing communication is
maintained.
To enter signal strength menu (see step 5 for more detail)
Press + & - for approx. 5 secs, then scroll (+/-) to show
INST-S,
• press ( ) to enter the installer menu,
• Press +/- until 11 WIRELESS is shown,
• press to enter, ( )
• press +/- to show 13 SIG-LEVEL as shown,
• press to see the current signal strength.( )
Step 4 (Continued) Step 5: Installer Settings
Customize the MiStat according to application needs.
Step 1: Mounting the Wallplate Step 2: Wiring
! IMPORTANT:
Installation must only be carried out by a
qualified electrician or heating engineer.
Make sure mains input has a 3 amp fuse.
! CAUTION! Before installation, make sure the
mains supply is switched off!
Option 2: Using an existing wall-plate
Loosen the securing screws on the old receiver
and unplug it. Check that there’s 20mm clearance
to the right of the wall-plate and 25mm above it.
Check the wiring diagram for your product model
to compare terminals and, if necessary, change
the wiring of the wall-plate to suit. Now plug the
MiStat R unit into the wall-plate and tighten the
securing screws.
Check the 3A fuse, and switch on the mains.
Option 1: Fitting a new wall-plate
The ideal location is close to the boiler or central
heating system. For the best performance install
in an open space, at least 30cm distance from
any metal objects including wall boxes and the
boiler housing. It is recommended that the
MiStat R is mounted on the wall nearest the final
location of the MiStat C room unit and not less
than 30cm from the boiler side panel.
Loosen the securing screws, remove the
wallplate and, if surface wiring is to be used,
snap out the cable entry strip on the bottom
edge of the wallplate with a pair of pliers. Fix the
wallplate, terminals at the top, either direct onto
the flat wall using wall plugs and no 6 x1” wood
screws or on a plastic flush mounting single
conduit box using M3.5 x 14 screws. Check that
there’s 20mm clearance to the right of the wall-
plate and 25mm above it. Complete the wiring
to the MiStat R wallplate in accordance with the
wiring diagram in step 2, to comply with current
IEE regulations. Place the MiStat R onto the
wallplate and tighten the securing screws.
Check the 3A fuse, and switch on the mains.
Warning: Installing the MiStat R too close to the
metal side panel or mains cables may interfere
with the radio signal.
→ →
! DO NOT
use a surface
mounting box
This product is double insulated and
does not require an earth connection.
The MiStat R should be wired to the
boiler or central heating wiring using the
correct type of cable or flex. The MiStat
R should be wired to replace hard wired
room or programmable thermostats,
as shown on the system or boiler wiring
diagrams.
Always check other manufacturers
instructions for compatibility.

To exit Installer Settings
Press +/- until ‘DONE’ is shown, then press ‘Select’ or
press + & – keys for approx. 5 seconds to exit. If there
is no key pressed for 2 Minutes, the system will exit the
menu, any changes will be saved.
1. Turn on power for the receiver. The red lamp will
come on. (if green lamp is visible, the device is
already bound, no further action needed here)
(If a separate programmer/Timer is fitted, ensure
that it is switched on)
2. Push the button for >5 Seconds and the LED will
flash red yellow green --- -red yellow - green
3. Enter binding mode on the corresponding
MiStat room unit, see Step 5: Installer settings ,
item 11
Important: It is essential, that the binding is
carried out between the corresponding room
unit and the receiver
4. If binding is successful, the signal strength will
be indicated on both the MiStat room unit and
the MiStat receiver as follows. If unsuccessful,
FAILED will be displayed. If POOR SIGNAL
is displayed, look for a better location. If NO
SIGNAL is displayed, try connecting again with
the room unit in a different position.
MiStat Room Unit
MiStat Receiver
Immediately after binding, these signals will indicate
the signal quality for 1 minute.
three green flashes = Very good signal
double amber flashes = Good signal
single red flashes = Poor signal
steady red = No signal
To check the wireless connection
A green lamp on the receiver will indicate a good RF
connection.
To enter Installer Settings
Press + & – keys for approx. 5 Seconds to enter the
settings menu as shown.
Note: If not bound, the bind screen will be visible.

Step 4: Mounting Options
The MiStat C should be located in a convenient position
for the end user, close to the domestic hot water cylinder
being controlled.
Once the best position has been identified, the MiStat
C should bexed to the wall using the wall bracket as
shown.

Cylinder Thermostat Sensor
Locate the external sensor terminal block on the lower
edge of the MiStat C thermostat, connect a 2-core
cable, cut to the required length to reach the sensor
position. Connect to the sensor in the position shown
and fold wires back through the cable grip & out
through the cable entry, re-assemble the housing.
Clip the spacer
provided onto
the sensor
housing
The sensor should be installed approximately one
third of the way up the hot water cylinder. With pre-
insulated cylinders, mark the position and size, and
remove just enough insulation to allow the sensor to fit
against the metal of the cylinder in the recess formed.
The plastic covered spring fixing cable should be cut
to an un-stretched length of approximately 60-75mm
(2½”-3”) less than the circumference of the cylinder
and the hook and eyelet should be screwed into the
ends. Stretch the cable round the cylinder, over the
insulation, and position it in the groove across the front
of the sensor housing, Engage the hook and eyelet.
