T4R Thermostat
Wireless Programmable Thermostat
 Quick Start Installation Guide

Compatible with 24-230V on/off & OpenTherm appliances such as gas boilers, combi-boilers, and zone valve applications. Not compatible with 230V electric heating.

Installation in 3 steps…

Must be installed by a competent person.
To ensure your safety make sure the mains power is switched OFF before accessing wiring.

Wire the Receiver Box

Find a suitable location near to the boiler, leaving at least 30cm distance from any metal objects including metal wall boxes and boiler housing.

A) Wall box or Rear
Wiring Hinge opens the terminal block flap to access the cables and wall box screw holes.		 B) Surface
Wiring Use the cable clamps to secure the surface wiring.
C) Replace the cover
Locate the hinges at the top of the cover and wall plate, close the cover and secure with the screw.

To prevent a short circuit from a loose wire 

  • When using multi-core cables: Only remove enough outer insulation to allow secure fixing of the cores into the terminal block.
  • When using single-core cables: Secure them together with a cable tie as close as possible to the terminal block.

Power Up and Test

A) Power Up the Thermostat
Remove the battery tab and clip the thermostat onto the table stand or wall bracket. Find a suitable location for the thermostat away from draughts, direct sunlight, or other heat sources.
B) In the Power Up Menu that appears, by pressing + and –  select your language and adjust the year, month, day, time, and the number of periods.
C) Power Up the Heating System and Receiver Box and do a quick functional test of the receiver box to check that it switches the boiler.

Configure the System

Specific settings for the thermostat and heating system can be configured in the advanced menu.
Press and hold and then buttons together until the display changes (approx. 3sec).

A) Press√ and buttons to navigate through the parameter list B) Press+ and- buttons to change a parameter
C) Press√ the button to save the change (or press to cancel the change) D) Press the button to exit the advanced menu and save any changes

To rebind the thermostat and receiver box
The thermostat and receiver box in this pack are pre-bound. Follow these instructions only if a binding is required.
To enter the binding menu press and hold and then– buttons together until the display changes (approx. 3sec), and follow steps A) to C) above to navigate the binding parameters. Keep at least 1m between devices during binding.

No Description Settings (default in bold)
RF Binding Mode 0, 1 = Enter bind mode
RF Signal Strength Test 0, 1 = Perform Signal Test
Delete RF Binding Data 0, 1 = Delete Bind Data

A) Clear the binding data from the Receiver Box:
Press & hold the reset ‘pinhole’ button for 3sec.
B) Put the Receiver Box into bind mode:
Hold button for 3sec – button lights ORANGE for 3sec followed by LED flashing ORANGE.
C) Clear the binding data from the Thermostat:
Change parameter No 14 C (Delete RF Binding Data) to ‘1’ and press
D) Put the Thermostat into bind mode:
Change parameter No 14 A (RF Binding Mode) to ‘1’ and press
If successful the Receiver Box LED will turn solid  GREEN and the Thermostat will show

Troubleshooting

What’s happening? What it could mean… How to fix it…
The thermostat display is blank Batteries exhausted installed incorrectly or the tab hasn’t been removed Pull thermostat from wall bracket or table stand and check battery installation –  replace batteries if necessary
Display = Battery power is critically low Pull thermostat from wall bracket or table stand and check battery installation – replace batteries if necessary
Display = Faulty temperature sensor Replace thermostat or check the wiring to remote temperature sensor if fitted
The thermostat shows heat demand but the boiler doesn’t respond Boiler (water) already t temperature Normal behavior – wait for the water temperature to drop
Faulty wiring connection Check wiring at thermostat and boiler terminals
Thermostat display shows and Receiver Box LED is flashing RED Wireless communication with Receiver Box is lost Move thermostat to a location where wireless communication is reliable
Thermostat display shows and Receiver Box LED is OFF Thermostat and Receiver Box not bound Follow the Wireless Binding Instructions
Receiver Box LED is flashing ORANGE Receiver Box is in bind mode Wait for bind mode to time out (3min) or bind a Thermostat
