Mounting
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.
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
Installation
- Press the button on the bottom of the thermostat.
- The front housing will detach from the baseplate.
- Insert the batteries (provided) into the thermostat.
- Mount the unit as described in section 3. Ensure the cable sensor is connected to terminals Con 3 and Con 4.
- Offer the baseplate up to the thermostat. Snap it into position to close.
CAUTION!
Only qualified electricians or authorised service staff are permitted to open
the thermostat.
Ensure that this wireless enabled thermostat is installed 1 metre from any
metalic object, television, radio or wireless internet transmitter.
