a Mounting of temperature sensor
ON CYLINDER: To ensure accurate control of your cylinder, the temperature
sensor should be mounted on the bottom 1/3 of the cylinder. It is essential
that the sensing element is in direct contact with the cylinder and that there
is no insulation between it and the cylinder. 60°C is the temperature level
required in order to prevent the build up of legionella bacteria. The
temperature sensor can be fixed to the cylinder using the provided foil tape.
ON PIPEWORK: To ensure accurate control, the temperature sensor should be
mounted on the pipework as tightly as possible. It is essential that the
sensing element is in direct contact with the pipework and that there is no
insulation between it and the pipework. The temperature sensor can be fixed to
the pipework using the provided foil tape. !
b Mounting of thermostat
The thermostat should be mounted in a position that will make reading the
display conventient.
The thermostat can be fitted to:
- Recessed conduit boxes
- Surface mounting boxes
- Directly on walls !

the Code button. This is located inside the housing on the Printed Circuit
Board.
On the timeswitch / programmer, the available zones will begin to flash. Press
the button for the zone you wish to connect the thermostat to.
The wireless symbol appears on the screen.
The thermostat will count upwards to the number of the zone that it is paired
with. When it reaches the number of the zone that it is paired with press the
hand wheel on the thermostat.
The timeswitch / programmer is now operating in the wireless mode.
The temperature of the wireless thermostat is now displayed on the programmer.
Repeat this process for the second, third and fourth zone if required.
To disconnect the RF thermostat with the programmer
Lower the cover on the front of the timeswitch / programmer. Move the selector switch to the RUN position.
On the timeswtich/ programmer, press the ) button for 5 seconds.
This will take you into the Wireless Connect screen.
