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

qualiﬁ ed 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 ﬁ nal

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 ﬂ at wall using wall plugs and no 6 x1” wood

screws or on a plastic ﬂ ush 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 ﬂ ex. 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 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 ,

it em 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 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 lamp on the receiver will indicate a good RF

connection.

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 identiﬁ ed, the MiStat

C should be ﬁ xed to the wall using the wall bracket as

shown.

Wiring

Cylinder Thermostat

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 ﬁ t

against the metal of the cylinder in the recess formed.

The plastic covered spring ﬁ xing 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.
