Press the reset button on the PCB to initiate the reset
process.
Rotate the hand wheel clockwise until ‘YES’ appears on the
screen.
Press the hand wheel once to confirm the setting.
The thermostat has now been reset, and the current temperature
will appear on the screen.

Boost Function

To boost the heating for a specific duration:

Press the boost button once, twice, or three times to boost the
heating for 1, 2, or 3 hours respectively.
‘+1H’, ‘+2H’, or ‘+3H’ will appear on the screen to indicate
the boost duration.

3a Mounting of temperature sensor

Code button

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.
3b Mounting of thermostat
The thermostat should be mounted in a position that will make reading the display conventient. The thermostat can be fitted to: 1. Recessed conduit boxes
2. Surface mounting boxes 3. Directly on walls
4. Installation
