How your programmable thermostat works
When the thermostat is in the AUTO mode, it will operate according to the
times and temperatures that have been programmed. The user can select
from 6 dierent programs per day - each with a time and a temperature.
There is no OFF time, only a higher and a lower temperature.
If the user wants the thermostat to be OFF at a certain time, set the
temperature for this time to be low. The thermostat will turn ON if the room
temperature is lower than the setpoint for the current period.
Example: If P1 is set to be 21˚C at 6am, and if P2 is set to be 10˚C at 8am, the
thermostat will look for the temperature to be 21˚C between 6am and 8am.
3. Mounting
The mounting height should be 1.5 metres above the oor level.
The thermostat should be wall mounted in the room where the heating is to
be controlled.
The place of installation should be chosen so that the sensor can measure the
room temperature as accurately as possible.
Choose the mounting location to prevent direct exposure to sunlight or other
heating / cooling sources when mounted.
The unit can be tted to:
1. Directly on walls.
2. Table mounting with stand provided.
Operating Instructions
CAUTION!
The thermostat must not be left unsupervised
when open. (Prevent non specialists and especially
children from gaining access to it.)

22. Installer menu (without OpenTherm® connected)
To access the installer menu, you must hold Prog and OK for 5 seconds.
When in the installer menu, press + - and OK to navigate and select. Use
AUTO, MAN or OFF to go back a step.

P0 6: Exit
P0 1: Mode (Normal / Optimum Start / Tpi)
Normal Mode (Nor)
When the thermostat is in Normal mode, the thermostat will try to reach the
target temperature after the program changes.
Example: Program 1 on the thermostat is 21°C for 06:30am and the room
temperature is 18°C. The thermostat will start the heating at 06:30am and the
room temperature will start to increase then.
Optimum Start Mode (OS)
When the thermostat is in Optimum Start mode, the thermostat will try to
reach the target temperature by the start time of the next switching time.
This is done by setting the Ti (time interval) on the thermostat in this menu
to 10, 15 or 20. This will allow the thermostat 10 mins, 15 mins or 20 mins to
increase the room temperature by 1°C.
Ti can be set when OS is selected in the installer menu.
To achieve the target temperature when the program starts, the thermostat
will read:
1. The Room Temperature (RT)
2. The Setpoint Temperature (ST)
3. The Target Temperature Dierence (TTD) is the dierence between
the setpoint temperature and the room temperature .
The time (in minutes) that it will take to overcome (TTD) is called Optimum
Start Time (OST) and its maximum value is 3 hours = 180 mins. This is
subtracted from the start time.
As the temperature increases the thermostat will recalculate the OST if the
temperature is increasing too quickly.

Time Proportional Integral Mode (TPi)
When the thermostat is in TPi mode and the temperature is rising in the
zone and falls into the Proportional Bandwidth section, TPi will start to
aect the thermostats operation. The thermostat will turn on and o as it
gains heat so that it doesn’t overshoot the setpoint by too much. It will also
turn on if the temperature is falling so it doesn’t undershoot the setpoint
which will leave the user with a more comfortable level of heat.
There are 2 settings that will aect the thermostats operation:
1. The Number of Heating Cycles Per Hour
2. The Proportional Bandwidth
CyC - Number of Heating Cycles per Hour:
This value will decide how often the thermostat will cycle the heating on
and o when trying to achieve the setpoint temperature. You can select
2/3/6 or 12.
Pb - Proportional Bandwidth:
2˚C
This value refers to the temperature below the setpoint at which the
thermostat will start to operate in TPi Control. You can set this temperature
from 1.5˚C to 3.0˚C in 0.1˚C increments.

Heating On Heating O
Example – Program 1 on the thermostat is 21°C for 06:30am and the room temperature is
18°C. The thermostat will start the heating at 06:30am and the heat will start to increase
then but will switch itself o before it reaches temperature and allow the room temperature
to increase naturally – this cycle may begin again if the thermostat isn’t reaching
temperature.
This menu allows the installer to change the minimum and maximum
temperature range that the thermostat can be set at. Defaults are 35°C for
Hi and 5°C for Lo.
This menu allows the installer to change the switching dierential of the
thermostat when the temperature is rising and falling.
HOn is the fall in temperature – Default – 0.4°C. This will allow a fall of 0.4°C
from the setpoint before the thermostat turns on again.
HOFF is the rise in temperature – Default – 0.0°C. This will allow the
temperature to rise 0°C above its setpoint.
This menu allows the installer to re-calibrate the thermostat. The current
temperature will be displayed on the screen and can be adjusted by
pressing the up and down buttons.
ON
This menu allows the installer to activate or de-activate frost protection.
When frost protection is activated the thermostat will switch on the boiler
when the temperature drops below 5˚C.
This menu allows the installer to return to the main interface. It is also
possible to exit the installer menu by pressing AUTO, MAN or OFF whilst in
the installer menu.
