Safety Information
IMPORTANT INFORMATION: Installation should only be carried out by a qualified 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.
Installation
Step 1 - Identify Suitable Location
Before making any permanent fixtures 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 floor temperature only. When installed in this way, it is not possible to directly control the heating based on the
room air temperature, only the floor surface temperature.
Step 2 - Installation and Wiring Connection
Gently press a flat head screwdriver
into the plastic release clips
highlighted above and pull face
outwards, unclipping from the base.
Place the frame and thermostat
face somewhere safe.
