Programmable Thermostat WA-XSTAT
I N S T R U C T I O N S
English
The electronic comfort controller is a clock
thermostat that can be programmed to function
as a floor temperature controller and room
temperature controller with a limitation function.
The thermostat is intended for mounting in a
55 mm standard wall socket. The operating area
ranges from +0° to +30°C. The thermostat
incorporates a clock enabling the programming
of several setback functions.
Controller setting WA-XSTAT
Program choice:
Floor temperature control
Floor temperature control with 2 sensors
Air temperature control
Air temperature control with floor
temperature limit
Regulator control
External control
The controller is designed in accordance
with current product standard EN 60730-
2-9, and fulfill hereby the requirements to both
LVD and EMC directives.
The controller must not be put into operation
until it has been ascertained that the entire
installation complies with current general safety
requirements for electrical installations.
The warranty is only valid if the controller has
been put into operation in accordance with the
operating instructions supplied with the
controller and these installation instructions.

The controller is maintenance-free.
Control pollution degree: 2
Pollution degree 2 is representative of normal
household air circulation.
Overvoltage category: III
Classification
The product is a class II device (reinforced
insulation) and the product must be connected
to the following conductors:
1) Phase (L)
2) Neutral (N)
The thermostat is constructed to store the clock
up to 4 hours at an occasional voltage
interruption. It is not suitable for use by regular
voltage interruptions. (Example: Power term
applications). At such conditions a constant
power supply for the thermostat must be
ensured.
WARNING – Important Safety Instructions
Isolate supply before carrying out any
installation or maintenance work on this control
unit and associated components. This control
unit and associated components should only be
installed by a competent person (i, e qualified
electrician). Electrical installation to be in
accordance with latest IEE Wiring Regulations
and appropriate Statutory Regulations.
Mounting of sensor
Floor sensor: Placed in an approved non
conductive installation pipe in accordance with
EN 61386-1, which is embedded in the floor.
(fig. 3). The pipe is closed in the end and placed
as high as possible in the concrete layer. The
installation pipe must be centered in between
the heating cable.
The enclosed 3 meter sensor cable can be
extended up to 100 m by means of a separate
cable. If the extension cable is lighter than
H05VV-F, it shall equally be installed in an
unbroken installation pipe between the sensor
cable and the extension cable. Two remaining
cores of a multi-core cable which, for example,
supplies current to the heating wires of a floor
heating system, must not be used. The
switching peaks of such current supply lines
may create interfering signals that prevent
optimum controller function. The two-corecable
must be placed in a separate pipe.
Controller installation site
The controller must be mounted on the wall so
that air can circulate freely around it (fig. 4). An
installation site must be selected where the
controller is not exposed to foreign energy
sources, e.g. solar radiation. The controller must
not be exposed to draughts coming from, for
example, windows, doors or cold outer walls.
The controller has a built-in fault interrupter
circuit which interrupts the heating in case of
disconnected or short-circuited sensor.
Mounting of controller
The single gang mounting box must have a
debt of no less than 25 mm.
1. Use a screwdriver in both sides to open the
lock.
The cover must be dismounted (fig. 1).
2. Connect cables according to the diagram
(fig. 2a-2b).
All electrical connections must be performed by
a fully qualified and Part P certified electrician.
3. The thermostat is mounted in the wall
socket. The cover is remounted.
Programming
(See user manual)
The controllers are delivered with a pre-installed
setback programme.
If the pre-installed setback programme is not
used, there are different programmes which can
be selected and used on the required days.
The controllers calculate when the heating is to
be switched on to make sure that the comfort
temperature is obtained to the required time.
Fault location
If the sensor is disconnected or short-
circuited, the heating system is switched off.
The sensor can be checked according to the
resistance table fig. 5.
Environment and recycling
