2XT6R SMART THERMOSTAT & 2-CHANNEL RECEIVER BOX
APPLICATION MANUAL
With the new 2-channel Receiver box (R6H911RF) and
2x a T6R wireless smart thermostats (T6H700RW)
automatic time and temperature control of 2 heating
zones and a boiler for homes and apartments can be
managed.
It’s compatible with 24-230V on/off and OpenTherm®
appliances such as gas boilers, combi-boilers and heat
pump. Also works with zone valve applications but not
with electric heating (240V).
The solution is designed with the installer in mind.
The 2-channel Receiver box offers mounting options for
directly on the wall or on a wall box. Wiring can be from
below or from the back by lifting the terminal platform,
which makes installation quick and easy.
The T6R wireless thermostat has a high contrast PMVA
display with dynamic text line and touch screen buttons.
The thermostat has a simple programming philosophy to
make it easier to install and very user friendly.
The 2-zone solution is ideal for consumers who want to
split the comfort control of their home in 2 areas, like
upstairs and down-stairs or a living and working area.
The solution offers remote comfort control of both zones
via the Honeywell Home app.

Special Features
Description
Heat Range
The normal lower temperature limit of 5 oC can be increased up to 21 oC to protect the
inhabitants from cold conditions. This is a useful feature aimed at supporting the elderly,
children and disabled inhabitants.
The normal upper temperature limit of 35 oC can be reduced down to 21 oC to save energy. This
feature is useful for leased homes and apartments.
Schedule options
The thermostat has 2 default schedules: daily (every day) and 5+2 (week + weekend days)
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 oC. 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 Combi-boilers have a small internal storage for hot tap water. By keeping a number of liters of hot water, the
appliance can supply hot tap water directly without having to heat it up first. With a longer period of none use or absence,
for example sleep or holiday, the hot water storage does not have to be kept at a high temperature.
The T6/T6R thermostat can provide additional savings here. With the last programmed period (sleeping)
the hot water status can easily be switched to a saving level or completely be switched off.
With these Combi-boilers, a menu "Hot water during sleep" (on/off) will be available in the installer menu (page 6).
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.

HEAT DEMAND CONTROL
The control of the heat demand of the 2 zones depends on the applied boiler type.
An on/off boiler or an OpenTherm® modulating boiler can be applied.
The 2-channel Receiver box receives from both zone thermostats the heat demand and will control the
corresponding zone valve via the relay contact to open.
For the cycle rate setting recommend the standard setting 6x per hour.
When an on/off boiler is applied, it can only be controlled on/off by means of the zone valve end switches
For an OpenTherm® boiler, use the OpenTherm® connection on the 2-channel Receiver box.
ON/OFF controlled boiler
The boiler will be switched on when one of the zone valves is completely opened and the end switch switches.
When both end switches are not switched, the boiler is off.
The cycle rate setting determines also the cycle rate of the boiler.
There is no synchronization of the heat demand of the 2 zone thermostats, which could cause the boiler to
switch off (end demand of a zone) and almost instantly switch on again by the demand of the other zone.
Some boilers have an anti-cycle time, which prevents them from switching on directly again.
OpenTherm® controlled boiler
When one of the zone thermostats communicates a demand the OpenTherm® will also be receiving a heat
demand. When both zones no longer require heat the demand is taken away and the boiler will switch off.
The 2-channel Receiver box constantly compares the demand of both zones and communicates the highest
demand to the OpenTherm® boiler.
