Special Features		Description
Opentherm®		By connecting the T4M to an OpenTherm® appliance various specific data can be viewed. The data is depending on what the appliance is providing.
Heat range		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.
Schedule options		The thermostat has the 5+2 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
External temperature sensor (only for wired versions)		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
Optimisation (optimum start, optimum stop and delayed start)		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.
Clock setting		Change display format (default 24hr) and adjust time and date.
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. Useful if the homeowner wants the reading to match another appliance temperature display.
Binding (only for T4R)		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		Reset the thermostat back to factory default settings, reset the schedule to default.
Failsafe		When the temperature sensor fails(T4,T4M) or the radio communication between the Thermostat and the Receiver box is lost the device will cycle the demand 20% On / 80% Off

INSTALLATION

To ensure your safety, always make sure mains power is switched OFF before accessing wiring.
Before removing the old thermostat take a picture of the old thermostat’s wiring as a reference then proceed to installation.

The T4 thermostat should not be placed near draughts, in direct sunlight or near heat sources. It should be at least 1.2 – 1.5 meters from the floor.

Prepare Receiver Box (T4R only)

Needed during installation:

• Cable with 2 wires from boiler to Receiver Box (R4H910RF1004).
• The Receiver Box requires 230V power.

Find a suitable location near the boiler. Leave at least 30cm distance from any metal objects including wall boxes and boiler housing.
Loosen the front screw to remove cover or tighten it when the cover is back in position.

Install Receiver Box (T4R only)

• A. Wall box or Rear wiring
  Hinge open the terminal block flap to access the cables and wall box screw holes
• B. Surface wiring
  Hinge open the terminal block flap to access the cables and wall box screw holes
• C. Replace cover
  Locate the hinges at the top of the cover and wall plate, close the cover and secure with the screw.

Complete installation(T4R)
Turn mains powers ON to the heating application and the receiver box

Install Thermostat(T4 and T4M only)

• A. Wall plate
  Using a screwdriver open wall plate terminal cover to connect wires.
• B. Surface wiring
  Connect wires according to wiring diagrams and clip the cover closed.
• C. Place thermostat
  Attach the thermostat to the wall plate when finished

Power Up the Thermostat (T4 and T4R only)
Remove the battery tab and clip the
thermostat onto the wall-plate.

Setup and Configuration
After power up, the language selection is displayed on the thermostat’s screen.

BINDING(T4R only)
The T4R thermostat wireless kit comes pre-bound from the factory. The binding operation described below is only required if:

• The T4 thermostat or the Receiver box is replaced
• The T4 thermostat or the Receiver box has incorrect or no binding data stored

To bind/rebind
Note: When the Receiver box has been bound before, first press with a small pin the pinhole for approximately 3 seconds to reset the binding, LEDs will flash amber for a moment.

1. Put the Receiver box into binding mode by pressing the button for 3 secs. The LED will flash amber.
2. Enable binding on thermostat:
   Enter binding menu by pressing and hold the for 3 secs and the press the – button.
   Change parameter 14A to 1 and press to confirm
3. When binding is successful:
