Step 1 - Identify Suitable Location
Step 2 - Installation and Wiring Connection
Before making any permanent xtures it is recommended identifying your preferred location for the thermostat. It
should be located in an area with good ventilation. It should not be beside a window/door, in direct sunlight or above
another heat generating device (e.g. radiator or TV).
BATHROOM INSTALLATIONS: When installing the thermostat within a bathroom it MUST be mounted outside of Zone 2
in accordance with Wiring Regulations. If it is not possible to identify a suitable location outside of Zone 2 within the
bathroom, then it is recommended that the thermostat is installed in the adjacent room and set to control the heating
by oor temperature only. When installed in this way, it is not possible to directly control the heating based on the
room air temperature, only the oor surface temperature.
IMPORTANT INFORMATION: Installation should only be carried out by a qualied and competent electrician. The
P-Stat + requires a permanent power supply from a 30mA RCD protected circuit in accordance with the current edition
of the Wiring Regulations. The thermostat and its power supply should be isolated from the mains supply throughout the
installation process. Ensure that wires are fully inserted into the terminals, with no bare wire visible and secured. Any
free strands should be trimmed, as they could otherwise cause a short-circuit.

Open Window Function - The P-Stat + features open window function which detects when there is a sudden drop in
temperature (1.5°C or more within 3 minutes) when a window is opened and will switch your heating o saving you
energy. The heating will reactivate if the temperature increases again (1.5°C in 30 minutes). PRESS any button to
return to heating schedule mode.
