Special Features
Description
Optimisation (optimal
start, optimal stop and
delayed start)
Optimal Start: learns how long it takes your system to reach the programmed temperature. It
turns on the heating system earlier to make sure it’s comfortable at the scheduled time.
Optimal 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
Clock setting
Change display format (default 24hr) and adjust time and date.
When connected to Internet time and date will be synchronized
Low Load Control
If the Receiver box is connected to an OpenTherm appliance this setting is used in the
demand control. When an appliance is no longer able to modulate lower the control switches
from modulating control to low/off control.
Temperature Offset
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 +/- 1,5
o
C. This feature is
useful if the homeowner wants the reading to match another appliance temperature display.
Binding
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
Menu to reset the thermostat back to factory default settings, reset the schedule to default
settings, reset the Wi-Fi and Homekit settings.
Failsafe
When the radio communication between the Thermostat and Receiver box is lost for longer
than 1 hour the Receiver box will start to cycle the demand 20% on / 80% off.
OPENTHERM® COMMUNICATION
OpenTherm® is a manufacturer independent communication protocol between modulating appliances (boilers, air heaters
and heat recovery units) and room thermostats.
Via the OpenTherm® protocol, the Receiver box of the T6 / T6R thermostat constantly communicates with the connected
appliance.
Modulating
The T6/T6R thermostat controls, via the Receiver box, the OpenTherm® communicating appliance modulating. This means
that, depending on the heat demand, the burner capacity is adjusted in the appliance. This creates a very accurate control
of the room temperature.
On top of that, this method of temperature control is more energy-efficient and environmentally friendly.
Low Load Control
When a boiler is no longer capable of modulating back it will stop the burner and then will be a cycling on it's own
continuously during this low control setting (requested water temperature).
In order to have a proper performance and to switch the pump on/off as well we created low load control. This is cycling
between off and min modulation level.
The cycle rate is related to the time the water temperature is cooling off below the control setpoint (demand) and the on
time of the boiler to get heated to the control setpoint.
It's an algorithm which optimizes the cycle rate and tries to get the boiler on for the longest time.
Hot water control
Most
OpenTherm®
Combi-boilers have a small internal storage for hot tap water or are connected to a large storage tank
which is kept on temperature. With a longer period of none use or absence, for example away during the day, sleep or
holiday, the hot water storage does not have to be kept at a high temperature.
The T6R-HW thermostat can provide additional savings here with a dedicated Hot water schedule. The schedule provides 3
on periods per day which can be programmed. Also during the Holiday the hot water status can be set to off.
OpenTherm® data
De T6/T6R thermostat offers the ability to view some appliance data via de OpenTherm® communicatie.
See table on page 6 which data can be viewed.
Note: Depending on the connected appliance, more or less data is displayed on the T6/T6R thermostat and certain
settings of the appliance may or may not be changed from the thermostat. Refer to the instruction manual of the
appliance for specific information.
