EUROSTER 2510
Introduction
Congratulations on the purchase of your new Digital Thermostat. Thanks to the latest microprocessor
technology, the thermostat offers many convenient and energy-saving features. Please read the following
instructions fully before installing your thermostat.
B: Overview of fe tures & functions
Your Digital Thermostat incorporates preset daily programs to suit different user lifestyles. The
thermostat can be programmed easily to accommodate e acting user needs. This user guide shows how
to get the best from your Digital Thermostat. It is powered by 2 AA batteries and can replace most
domestic thermostats.
C ution! The Digital Thermostat has been designed to switch a 230VAC supply. The ma imum load is 6
Amps (resistive)/ 2 Amps (inductive).
Inst ll tion
C ution! Electricity can be lethal. Before beginning any work, ensure that the electricity supply is turned
off at the mains. If in any doubt, contact a qualified electrician. If you currently have a thermostat
connected by two wires, you can replace it directly with your new Digital Thermostat. If you are not
replacing an e isting thermostat, you must install a two-wire cable to your heating system.
1. Before carrying out any installation work, choose an appropriate location for Digital Thermostat
using the following guidelines:
a) Mount the Digital Thermostat appro imately 1.6m above the
floor.
b) Only mount on interior walls (the thermostat is not for
outdoor use)
c) Avoid any location where the Digital Thermostat could be
e posed to direct sunlight.
d) Avoid any location in pro imity to a heater, cooker, ventilation
outlet or any appliance/fitting that generates heat.
e) Avoid any location where there may be concealed boilers, pipework or chimney flues.
f) Mount away from doors and the corners of rooms.
2. Detach the front cover by sliding it to the left. Remove screw in battery compartment. Open the
front housing from the base by lifting from the left hand side.
3. Unscrew the retaining screw to open the protective cover.
4. Mount the Thermostat base on the wall in the desired location, ensuring that the hole in the wall
is completely covered by the base. Check the wires come in through the protective cover hole.

5. Connect the two wires into terminals 1 & 2. The standard connections are shown on the pictures
(without neutral and earth conductor)
Note! If the e isting installation has neutral or earth conductors, these must not be connected to
the Digital Thermostat. They must be made electrically safe.
6. Reattach the protective cover to the Digital Thermostat's base and secure it with the retaining
screw.
7. Reattach the front housing to the Digital Thermostat's base and secure it with the retaining
screw.
8. Insert 2 AA batteries making sure they are the right way round as indicated and replace the
front cover.
Note: when replacing the batteries, the programs are held in memory for appro . 20 seconds
only.
9. Press the RESET key once and ensure the Digital Thermostat is in the INITIAL mode

Oper tion nd Progr mming
1. To set clock and day:
After inserting the batteries, or pressing the RESET key or key. The
thermostat will enter TIME ADJUSTMENT mode and the HOUR will start

C.
The Digital Thermostat is a weekly programmable thermostat, with 7
day/24 hour programs that can be set as required. For each hour you can set the Digital
Thermostat so that either the CT (COMFORT) or ET (EVENING) temperature mode
operates. The Digital Thermostat comes with a preinstalled program that will accommodate many
users' requirements

ET, or vice versa) until the temperature mode is programmed to activate again. If the thermostat is
currently running in ET mode, press the key to change to CT mode the thermostat will run CT mode

EUROSTER 2510 – USER MANUAL 5
until the ne t ET program period activates. Similarly if CT is running, press the key to change to ET
mode. The thermostat will continue to run in ET mode until the ne t CT program period activates.
Note: the first hour of override will only run for a ma imum of 45 minutes. Each subsequent hour of
override will function for the full hour. For e ample, 2 hours of override will function for 1 hour 45
minutes
Setting perm nent/v c tion temper ture override
The Digital Thermostat program can be overridden to give one constant temperature for any period
between 1 and 99 days. This is particularly useful if you are going on holiday. Press the key and the
day bar on LCD will flash. Use the +/- keys to set the number of days override required. Press the
key to confirm. Use the +/- keys to select the required temperature. Press the key to confirm.

Further djustment
The Digital Thermostat incorporates twin DIP switches on the circuit board at the rear of the front
housing.
DIP switch 1 adjusts the sensitivity of the thermostat. In the DOWN position if the temperature
variation is greater than 0.5°C the thermostat is activated. In the UP position it will activate if the
variation is greater than 0.2°C.
DIP switch 2 switches between HEATING and AIR CONDITIONING. DOWN position selects HEATING
control, UP position selects AIR CONDITIONING control.
Sensor oper tion
Your Digit l Thermost t uses n dv nced NTC thermistor to detect the temperature, located on
the lower left-hand side of the circuit board. If the sensor is accidentally touched, you must allow a few
minutes for the sensor to return to the normal temperature. The sensor measures the temperature once
a minute.
