Hiwell HT01-16RF Installation & Operating Instructions

HT01-16RF Electronic Heating Thermostat
The controller is designed in accordance with current product standard EN 60730-2-9, and hereby fufills 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 legislation applying to
electrical installations.
The warranty is only valid if the controller has been put into operation in accordance with the operating and installation instructions supplied with this
controller.
The HT01-16RF is an electronic on/off thermostat for control of temperature by means of an NTC sensor either placed externally or internally in the
thermostat.
The floor sensor should be installed within an approved non conductive
installation pipe in accordance with EN 61386-1, which is embedded in the
floor. The pipe (flexible conduit) should be placed as high as possible in the
subfloor. The floor sensor should be located equidistant between two runs of
the heating element with the tip at least 300mm away from the outside edge
of the heater.
The enclosed 3 meter sensor cable can be extended up to 50m 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. The installation pipe must not
contain any other cables, such as the supplies to the heating wire. The
switching peaks of such current supply lines may create interfering signals
that prevent optimum thermostat function. The heating supply cable should
be placed in a separate pipe.
In the event of sensor failure, replacement of the sensor can be carried out
with ease providing the sensor is installed within flexible conduit.
The floor sensor should never cross the heating element.

Placement of Thermostat

The thermostat is to be mounted on the wall with free air
circulation around it. Furthermore it has to be placed where it is
not influenced by any other heating sources (e.g. the sun), draft
from doors or windows, or by the temperature of an exterior wall.
The thermostat must be installed outside of rooms containing a
bath or shower. (Protective housing – IP20)

Electrical Connection

Electrical connections are to be made as detailed on
diagram.
The circuit supplying this controller must be protected by a
30mA RCD.
All electrical connections must be performed by a fully
qualified and part P certified electrician.
Any doubts surrounding the installation of this controller
should be passed to the distributer prior to installation.
Testing of all under-floor heating systems should take place
prior to floor coverings being installed.
IMPORTAT: ALWAYS DISCONNECT THE MAINS SUPPLY VIA THE SWITCH IN THE MAIN FUSE BOARD, CONSUMER UNIT BEFORE COMMENCING ANY
ELECTRICAL WORK. WHEN CONNECTING CABLES TO THE THERMOSTAT, ENSURE THAT ALL TERMINAL SCREWS ARE FULLY TIGHTENED AND THAT EARTH
WIRES ARE SLEEVED AND THAT NO BARE WIRES ARE SHOWING.
