INSTALLATION
Please read the important safety information at the start of this manual
before you begin to install the device.
The ideal position to locate the EP101 programmable heating controller is
about 1.5m above floor level. It should be mounted in a location where the
controller is easily accessible, reasonably lit and free from extremes of
temperature.
The electrical connections to the EP101 are made to the supplied industry
standard backplate. This simplifies installation, as no connections are made
to the controller itself. Connection details are shown below - no Earth
connection is required for the correct and safe operation of the EP101, but
a parking terminal is provided to connect an Earth wire if one is present.

After installing the backplate in a suitable location, wiring connections can be
made as shown above. The following criteria apply to the installation:
•
The incoming AC mains supply should be 230V AC and fused at 6 amps.
•
Optimum cable size for installation is 1.5 mm2; wiring colours should be
in accordance with the current requirements of the IEE Wiring Regulations.
•
Cable entry should be from the rear of the backplate.
•
All wiring connections should be securely made, and be firmly
gripped beneath the terminal square brass washer.
Do not restore the mains supply to the system until all associated items are fully
installed.
NOTE: All electrical installation work should be carried out
by a suitably qualified Electrician or other competent person.
If you are not sure how to install this programmable thermostat consult either
with a qualified electrician, heating engineer or your boiler / heating system
supplier for advice on how to continue.
Do not remove or refit the EP101 onto the backplate without the mains
supply to the system being isolated.

changing the jumper setting on the rear of the controller, as previously
described within the Installation section of this manual.

Normal mode. This will change the unit status to Programme Setting
mode.
The display will show programme number 1 and SET PROG, with all other
indicators cleared. The weekdays will be flashing to indicate they are the
selected item and are ready to be adjusted:
Press the UP or DOWN key to select the
