Step 6:
Commissioning
Note:
Only needed if not already bound, ie if
replacing either the MiStat thermostat or the
MiStat receiver.
1.
Turn on power for the receiver. The red LED will
come on.
If LED is green or Off, the device is already
bound, no further action needed here
(If a
separate programmer/Timer is fi tted, ensure
that it is switched on)
2.
Push the button for >5 Seconds and the LED
will fl ash red – yellow – green --- -red – yellow -
green…
3.
Enter binding mode on the corresponding
MiStat room unit, see Step 5: Installer settings
Important:
It is essential, that the binding is
carried out between the corresponding room
unit and the receiver
4.
The possible results are as follows;
1.
‘
Bind OK’ will be indicated on the MiStat
room unit if binding was successful.
After a few seconds the Signal strength will be
indicated on both the MiStat room unit and the
MiStat receiver, see below.
2
. ‘
Bind Failed’ will be displayed if
unsuccessful.
3.
If ‘Poor’ signal is displayed, look for a better
location.
4.
If ‘No Signal’ is displayed, try connecting
again with the room unit in a different position.

MiStat Receiver
Immediately after binding, these signals will indicate
the signal quality for 1 minute.
•
three green fl ashes = Very good signal
•
double amber fl ashes = Good signal
•
single red fl ashes = Poor signal
•
steady red = No signal
To check the wireless connection
A green LED on the receiver will indicate a good RF
connection.
From the Home screen, select
Settings
, then
Installer settings
as shown.
From here you can edit the
assigned zones, rename them if
required and adjust the Service
settings.
If using the Service feature,
remember to set the
Password
when complete.
Step 4:
Mounting Options
Once the best position has been identifi ed, the MiStat
should be fi xed to the wall using the wall bracket as
shown.
Care should be taken to mount the thermostat in a
position which is not subject to direct sunlight or
draughts. Preferably it should be mounted on an inside
wall about 1.2m (4ft) above the fl oor in a position where
it can respond to room temperature but away from the
direct infl uence of radiators or other appliances giving
off heat.
NB. MiStat can also be positioned using the table
stand included.

It has to be placed in a location where it will be able to
control the room temperature.
