Description
By connecting the T3M to an OpenTherm® appliance various specific data can be viewed. The
data is depending on what the appliance is providing.
The normal lower temperature limit of 5 °C can be increased up to 21 °C
to protect the inhabitants from cold. Useful if the inhabitants include the elderly, children or
disabled. The normal upper temperature limit of 37 °C
can be reduced down to 21 °C to save the homeowner energy. Useful if the homeowner rents
to tenants.
The thermostat has the 7 days by default, however it can be change to 7 days for different
schedule each day of the week or 1 day for having the same schedule during the week
An external temperature sensor can be fitted, allowing the thermostat to control the
temperature from another room or space, where it is inconvenient to locate the thermostat.
It will read the remote sensor every 1 minute. The sensor can be connected up to 50 meters
from the unit. Useful for commercial premises where the public may tamper with the product
Optimum Start: learns how long it takes your system to reach the temperature you want. It
turns on the heating system earlier to make sure it's comfortable at the scheduled time.
Optimum Stop: Saves energy and money by switching off a little bit earlier than the normal
programmed time. If the home is up to temperature, it will not notice the effect on the
temperature, but will show a difference in the fuel bill.
Delayed start: Saves energy by slightly delaying the start of heating depending on the
difference between the scheduled temperature and the actual room temperature.
Change display format (default 24hr) and adjust time and date.
If the Thermostat is located in a hot/cold location and cannot be moved because of wiring
then the measured/ displayed temperature can be adjusted by +/‐ 3 °C. Useful if the
homeowner wants the reading to match another appliance temperature display.
Menu to bind the Thermostat and the Receiver box, test the RF signal strength of the radio
communication and to clear an existing binding.
Reset the thermostat back to factory default settings, reset the schedule to default.
When the temperature sensor fails(T3,T3M) or the radio communication between the
Thermostat and the Receiver box is lost the device will cycle the demand 20% On / 80% Off
